gone out again in places. The wind dropped as suddenly as it had arisen soon after midnight.

In the evening Simpson gave us his first meteorological lecture–the subject, ‘Coronas, Halos, Rainbows, and Auroras.’ He has a remarkable power of exposition and taught me more of these phenomena in the hour than I had learnt by all previous interested inquiries concerning them.

I note one or two points concerning each phenomenon.

_Corona_.–White to brown inside ring called Aureola–outside are sometimes seen two or three rings of prismatic light in addition. Caused by diffraction of light round drops of water or ice crystals; diameter of rings inversely proportionate to size of drops or crystals–mixed sizes of ditto causes aureola without rings.

_Halos_.–Caused by refraction and reflection through and from ice crystals. In this connection the hexagonal, tetrahedonal type of crystallisation is first to be noted; then the infinite number of forms in which this can be modified together with result of fractures: two forms predominate, the plate and the needle; these forms falling through air assume definite position–the plate falls horizontally swaying to and fro, the needle turns rapidly about its longer axis, which remains horizontal. Simpson showed excellent experiments to illustrate; consideration of these facts and refraction of light striking crystals clearly leads to explanation of various complicated halo phenomena such as recorded and such as seen by us on the Great Barrier, and draws attention to the critical refraction angles of 32 deg. and 46 deg., the radius of inner and outer rings, the position of mock suns, contra suns, zenith circles, &c.

Further measurements are needed; for instance of streamers from mock suns and examination of ice crystals. (Record of ice crystals seen on Barrier Surface.)

_Rainbows_.–Caused by reflection and refraction from and through _drops of water_–colours vary with size of drops, the smaller the drop the lighter the colours and nearer to the violet end of the spectrum–hence white rainbow as seen on the Barrier, very small drops.

Double Bows–diameters must be 84 deg. and 100 deg.–again from laws of refraction–colours: inner, red outside; outer, red inside–i.e. reds come together.

Wanted to see more rainbows on Barrier. In this connection a good rainbow was seen to N.W. in February from winter quarters. Reports should note colours and relative width of bands of colour.

_Iridescent Clouds_.–Not yet understood; observations required, especially angular distance from the sun.

_Auroras_.–Clearly most frequent and intense in years of maximum sun spots; this argues connection with the sun.

Points noticed requiring confirmation:

Arch: centre of arch in magnetic meridian.

Shafts: take direction of dipping needle.

Bands and Curtains with convolutions–not understood.

Corona: shafts meeting to form.

Notes required on movement and direction of movement–colours seen–supposed red and possibly green rays preceding or accompanying movement. Auroras are sometimes accompanied by magnetic storms, but not always, and vice versa–in general significant signs of some connection–possible common dependents on a third factor. The phenomenon further connects itself in form with lines of magnetic force about the earth.

(Curious apparent connection between spectrum of aurora and that of a heavy gas, ‘argon.’ May be coincidence.)

Two theories enunciated:

_Arrhenius_.–Bombardments of minute charged particles from the sun gathered into the magnetic field of the earth.

_Birkeland_.–Bombardment of free negative electrons gathered into the magnetic field of the earth.

It is experimentally shown that minute drops of water are deflected by light.

It is experimentally shown that ions are given off by dried calcium, which the sun contains.

Professor Stoermer has collected much material showing connection of the phenomenon with lines of magnetic force.

_Thursday, May_ 4.–From the small height of Wind Vane Hill (64 feet) it was impossible to say if the ice in the Strait had been out after yesterday’s wind. The sea was frozen, but after twelve hours’ calm it would be in any case. The dark appearance of the ice is noticeable, but this has been the case of late since the light is poor; little snow has fallen or drifted and the ice flowers are very sparse and scattered.

We had an excellent game of football again to-day–the exercise is delightful and we get very warm. Atkinson is by far the best player, but Hooper, P.O. Evans, and Crean are also quite good. It has been calm all day again.

Went over the sea ice beyond the Arch berg; the ice half a mile beyond is only 4 inches. I think this must have been formed since the blow of yesterday, that is, in sixteen hours or less.

Such rapid freezing is a hopeful sign, but the prompt dissipation of the floe under a southerly wind is distinctly the reverse.

I am anxious to get our people back from Hut Point, mainly on account of the two ponies; with so much calm weather there should have been no difficulty for the party in keeping up its supply of blubber; an absence of which is the only circumstance likely to discomfort it.

The new ice over which I walked is extraordinarily slippery and free from efflorescence. I think this must be a further sign of rapid formation.

_Friday, May_ 5.–Another calm day following a quiet night. Once or twice in the night a light northerly wind, soon dying away. The temperature down to -12 deg.. What is the meaning of this comparative warmth? As usual in calms the Wind Vane Hill temperature is 3 deg. or 4 deg. higher. It is delightful to contemplate the amount of work which is being done at the station. No one is idle–all hands are full, and one cannot doubt that the labour will be productive of remarkable result.

I do not think there can be any life quite so demonstrative of character as that which we had on these expeditions. One sees a remarkable reassortment of values. Under ordinary conditions it is so easy to carry a point with a little bounce; self-assertion is a mask which covers many a weakness. As a rule we have neither the time nor the desire to look beneath it, and so it is that commonly we accept people on their own valuation. Here the outward show is nothing, it is the inward purpose that counts. So the ‘gods’ dwindle and the humble supplant them. Pretence is useless.

One sees Wilson busy with pencil and colour box, rapidly and steadily adding to his portfolio of charming sketches and at intervals filling the gaps in his zoological work of _Discovery_ times; withal ready and willing to give advice and assistance to others at all times; his sound judgment appreciated and therefore a constant referee.

Simpson, master of his craft, untiringly attentive to the working of his numerous self-recording instruments, observing all changes with scientific acumen, doing the work of two observers at least and yet ever seeking to correlate an expanded scope. So the current meteorological and magnetic observations are taken as never before by Polar expeditions.

Wright, good-hearted, strong, keen, striving to saturate his mind with the ice problems of this wonderful region. He has taken the electrical work in hand with all its modern interest of association with radio-activity.

Evans, with a clear-minded zeal in his own work, does it with all the success of result which comes from the taking of pains. Therefrom we derive a singularly exact preservation of time–an important consideration to all, but especially necessary for the physical work. Therefrom also, and including more labour, we have an accurate survey of our immediate surroundings and can trust to possess the correctly mapped results of all surveying data obtained. He has Gran for assistant.

Taylor’s intellect is omnivorous and versatile–his mind is unceasingly active, his grasp wide. Whatever he writes will be of interest–his pen flows well.

Debenham’s is clearer. Here we have a well-trained, sturdy worker, with a quiet meaning that carries conviction; he realises the conceptions of thoroughness and conscientiousness.

To Bowers’ practical genius is owed much of the smooth working of our station. He has a natural method in line with which all arrangements fall, so that expenditure is easily and exactly adjusted to supply, and I have the inestimable advantage of knowing the length of time which each of our possessions will last us and the assurance that there can be no waste. Active mind and active body were never more happily blended. It is a restless activity, admitting no idle moments and ever budding into new forms.

So we see the balloons ascending under his guidance and anon he is away over the floe tracking the silk thread which held it. Such a task completed, he is away to exercise his pony, and later out again with the dogs, the last typically self-suggested, because for the moment there is no one else to care for these animals. Now in a similar manner he is spreading thermometer screens to get comparative readings with the home station. He is for the open air, seemingly incapable of realising any discomfort from it, and yet his hours within doors spent with equal profit. For he is intent on tracking the problems of sledging food and clothing to their innermost bearings and is becoming an authority on past records. This will be no small help to me and one which others never could have given.

Adjacent to the physicist’s corner of the hut Atkinson is quietly pursuing the subject of parasites. Already he is in a new world. The laying out of the fish trap was his action and the catches are his field of labour. Constantly he comes to ask if I would like to see some new form and I am taken to see some protozoa or ascidian isolated on the slide plate of his microscope. The fishes themselves are comparatively new to science; it is strange that their parasites should have been under investigation so soon.

Atkinson’s bench with its array of microscopes, test-tubes, spirit lamps, &c., is next the dark room in which Ponting spends the greater part of his life. I would describe him as sustained by artistic enthusiasm. This world of ours is a different one to him than it is to the rest of us–he gauges it by its picturesqueness–his joy is to reproduce its pictures artistically, his grief to fail to do so. No attitude could be happier for the work which he has undertaken, and one cannot doubt its productiveness. I would not imply that he is out of sympathy with the works of others, which is far from being the case, but that his energies centre devotedly on the minutiae of his business.

Cherry-Garrard is another of the open-air, self-effacing, quiet workers; his whole heart is in the life, with profound eagerness to help everyone. ‘One has caught glimpses of him in tight places; sound all through and pretty hard also.’ Indoors he is editing our Polar journal, out of doors he is busy making trial stone huts and blubber stoves, primarily with a view to the winter journey to Cape Crozier, but incidentally these are instructive experiments for any party which may get into difficulty by being cut off from the home station. It is very well to know how best to use the scant resources that nature provides in these regions. In this connection I have been studying our Arctic library to get details concerning snow hut building and the implements used for it.

Oates’ whole heart is in the ponies. He is really devoted to their care, and I believe will produce them in the best possible form for the sledging season. Opening out the stores, installing a blubber stove, &c., has kept _him_ busy, whilst his satellite, Anton, is ever at work in the stables–an excellent little man.

Evans and Crean are repairing sleeping-bags, covering felt boots, and generally working on sledging kit. In fact there is no one idle, and no one who has the least prospect of idleness.

_Saturday, May_ 6.–Two more days of calm, interrupted with occasional gusts.

Yesterday, Friday evening, Taylor gave an introductory lecture on his remarkably fascinating subject–modern physiography.

These modern physiographers set out to explain the forms of land erosion on broad common-sense lines, heedless of geological support. They must, in consequence, have their special language. River courses, they say, are not temporary–in the main they are archaic. In conjunction with land elevations they have worked through _geographical cycles_, perhaps many. In each geographical cycle they have advanced from _infantile_ V-shaped forms; the courses broaden and deepen, the bank slopes reduce in angle as maturer stages are reached until the level of sea surface is more and more nearly approximated. In _senile_ stages the river is a broad sluggish stream flowing over a plain with little inequality of level. The cycle has formed a _Peneplain._ Subsequently, with fresh elevation, a new cycle is commenced. So much for the simple case, but in fact nearly all cases are modified by unequal elevations due to landslips, by variation in hardness of rock, &c. Hence modification in positions of river courses and the fact of different parts of a single river being in different stages of cycle.

Taylor illustrated his explanations with examples: The Red River, Canada–Plain flat though elevated, water lies in pools, river flows in ‘V’ ‘infantile’ form.

The Rhine Valley–The gorgeous scenery from Mainz down due to infantile form in recently elevated region.

The Russian Plains–Examples of ‘senility.’

Greater complexity in the Blue Mountains–these are undoubted earth folds; the Nepean River flows through an offshoot of a fold, the valley being made as the fold was elevated–curious valleys made by erosion of hard rock overlying soft.

River _piracy–Domestic_, the short circuiting of a _meander_, such as at Coo in the Ardennes; _Foreign_, such as Shoalhaven River, Australia–stream has captured river.

Landslips have caused the isolation of Lake George and altered the watershed of the whole country to the south.

Later on Taylor will deal with the effects of ice and lead us to the formation of the scenery of our own region, and so we shall have much to discuss.

_Sunday, May_ 7.–Daylight now is very short. One wonders why the Hut Point party does not come. Bowers and Cherry-Garrard have set up a thermometer screen containing maximum thermometers and thermographs on the sea floe about 3/4′ N.W. of the hut. Another smaller one is to go on top of the Ramp. They took the screen out on one of Day’s bicycle wheel carriages and found it ran very easily over the salty ice where the sledges give so much trouble. This vehicle is not easily turned, but may be very useful before there is much snowfall.

Yesterday a balloon was sent up and reached a very good height (probably 2 to 3 miles) before the instrument disengaged; the balloon went almost straight up and the silk fell in festoons over the rocky part of the Cape, affording a very difficult clue to follow; but whilst Bowers was following it, Atkinson observed the instrument fall a few hundred yards out on the Bay–it was recovered and gives the first important record of upper air temperature.

Atkinson and Crean put out the fish trap in about 3 fathoms of water off the west beach; both yesterday morning and yesterday evening when the trap was raised it contained over forty fish, whilst this morning and this evening the catches in the same spot have been from twenty to twenty-five. We had fish for breakfast this morning, but an even more satisfactory result of the catches has been revealed by Atkinson’s microscope. He had discovered quite a number of new parasites and found work to last quite a long time.

Last night it came to my turn to do night watchman again, so that I shall be glad to have a good sleep to-night.

Yesterday we had a game of football; it is pleasant to mess about, but the light is failing.

Clissold is still producing food novelties; to-night we had galantine of seal–it was _excellent_.

_Monday, May_ 8–Tuesday, May 9.–As one of the series of lectures I gave an outline of my plans for next season on Monday evening. Everyone was interested naturally. I could not but hint that in my opinion the problem of reaching the Pole can best be solved by relying on the ponies and man haulage. With this sentiment the whole company appeared to be in sympathy. Everyone seems to distrust the dogs when it comes to glacier and summit. I have asked everyone to give thought to the problem, to freely discuss it, and bring suggestions to my notice. It’s going to be a tough job; that is better realised the more one dives into it.

To-day (Tuesday) Debenham has been showing me his photographs taken west. With Wright’s and Taylor’s these will make an extremely interesting series–the ice forms especially in the region of the Koettlitz glacier are unique.

The Strait has been frozen over a week. I cannot understand why the Hut Point party doesn’t return. The weather continues wonderfully calm though now looking a little unsettled. Perhaps the unsettled look stops the party, or perhaps it waits for the moon, which will be bright in a day or two.

Any way I wish it would return, and shall not be free from anxiety till it does.

Cherry-Garrard is experimenting in stone huts and with blubber fires–all with a view to prolonging the stay at Cape Crozier.

Bowers has placed one thermometer screen on the floe about 3/4′ out, and another smaller one above the Ramp. Oddly, the floe temperature seems to agree with that on Wind Vane Hill, whilst the hut temperature is always 4 deg. or 5 deg. colder in calm weather. To complete the records a thermometer is to be placed in South Bay.

Science–the rock foundation of all effort!!

_Wednesday, May_ 10.–It has been blowing from the South 12 to 20 miles per hour since last night; the ice remains fast. The temperature -12 deg. to -19 deg.. The party does not come. I went well beyond Inaccessible Island till Hut Point and Castle Rock appeared beyond Tent Island, that is, well out on the space which was last seen as open water. The ice is 9 inches thick, not much for eight or nine days’ freezing; but it is very solid–the surface wet but very slippery. I suppose Meares waits for 12 inches in thickness, or fears the floe is too slippery for the ponies.

Yet I wish he would come.

I took a thermometer on my walk to-day; the temperature was -12 deg. inside Inaccessible Island, but only -8 deg. on the sea ice outside–the wind seemed less outside. Coming in under lee of Island and bergs I was reminded of the difficulty of finding shelter in these regions. The weather side of hills seems to afford better shelter than the lee side, as I have remarked elsewhere. May it be in part because all lee sides tend to be filled by drift snow, blown and weathered rock debris? There was a good lee under one of the bergs; in one corner the ice sloped out over me and on either side, forming a sort of grotto; here the air was absolutely still.

Ponting gave us an interesting lecture on Burmah, illustrated with fine slides. His descriptive language is florid, but shows the artistic temperament. Bowers and Simpson were able to give personal reminiscences of this land of pagodas, and the discussion led to interesting statements on the religion, art, and education of its people, their philosophic idleness, &c. Our lectures are a real success.

_Friday, May_ 12.–Yesterday morning was quiet. Played football in the morning; wind got up in the afternoon and evening.

All day it has been blowing hard, 30 to 60 miles an hour; it has never looked very dark overhead, but a watery cirrus has been in evidence for some time, causing well marked paraselene.

I have not been far from the hut, but had a great fear on one occasion that the ice had gone out in the Strait.

The wind is dropping this evening, and I have been up to Wind Vane Hill. I now think the ice has remained fast.

There has been astonishingly little drift with the wind, probably due to the fact that there has been so very little snowfall of late.

Atkinson is pretty certain that he has isolated a very motile bacterium in the snow. It is probably air borne, and though no bacteria have been found in the air, this may be carried in upper currents and brought down by the snow. If correct it is an interesting discovery.

To-night Debenham gave a geological lecture. It was elementary. He gave little more than the rough origin and classification of rocks with a view to making his further lectures better understood.

_Saturday, May_ 13.–The wind dropped about 10 last night. This morning it was calm and clear save for a light misty veil of ice crystals through which the moon shone with scarce clouded brilliancy, surrounded with bright cruciform halo and white paraselene. Mock moons with prismatic patches of colour appeared in the radiant ring, echoes of the main source of light. Wilson has a charming sketch of the phenomenon.

I went to Inaccessible Island, and climbing some way up the steep western face, reassured myself concerning the ice. It was evident that there had been no movement in consequence of yesterday’s blow.

In climbing I had to scramble up some pretty steep rock faces and screens, and held on only in anticipation of gaining the top of the Island and an easy descent. Instead of this I came to an impossible overhanging cliff of lava, and was forced to descend as I had come up. It was no easy task, and I was glad to get down with only one slip, when I brought myself up with my ice axe in the nick of time to prevent a fall over a cliff. This Island is very steep on all sides. There is only one known place of ascent; it will be interesting to try and find others.

After tea Atkinson came in with the glad tidings that the dog team were returning from Hut Point. We were soon on the floe to welcome the last remnant of our wintering party. Meares reported everything well and the ponies not far behind.

The dogs were unharnessed and tied up to the chains; they are all looking remarkably fit–apparently they have given no trouble at all of late; there have not even been any fights.

Half an hour later Day, Lashly, Nelson, Forde, and Keohane arrived with the two ponies–men and animals in good form.

It is a great comfort to have the men and dogs back, and a greater to contemplate all the ten ponies comfortably stabled for the winter. Everything seems to depend on these animals.

I have not seen the meteorological record brought back, but it appears that the party had had very fine calm weather since we left them, except during the last three days when wind has been very strong. It is curious that we should only have got one day with wind.

I am promised the sea-freezing record to-morrow. Four seals were got on April 22, the day after we left, and others have been killed since, so that there is a plentiful supply of blubber and seal meat at the hut–the rest of the supplies seem to have been pretty well run out. Some more forage had been fetched in from the depot. A young sea leopard had been killed on the sea ice near Castle Rock three days ago, this being the second only found in the Sound.

It is a strange fact that none of the returning party seem to greatly appreciate the food luxuries they have had since their return. It would have been the same with us had we not had a day or two in tents before our return. It seems more and more certain that a very simple fare is all that is needed here–plenty of seal meat, flour, and fat, with tea, cocoa, and sugar; these are the only real requirements for comfortable existence.

The temperatures at Hut Point have not been as low as I expected. There seems to have been an extraordinary heat wave during the spell of calm recorded since we left–the thermometer registering little below zero until the wind came, when it fell to -20 deg.. Thus as an exception we have had a fall instead of a rise of temperature with wind.

[The exact inventory of stores at Hut Point here recorded has no immediate bearing on the history of the expedition, but may be noted as illustrating the care and thoroughness with which all operations were conducted. Other details as to the carbide consumed in making acetylene gas may be briefly quoted. The first tin was opened on February 1, the second on March 26. The seventh on May 20, the next eight at the average interval of 9 1/2 days.]

_Sunday, May_ 14.–Grey and dull in the morning.

Exercised the ponies and held the usual service. This morning I gave Wright some notes containing speculations on the amount of ice on the Antarctic continent and on the effects of winter movements in the sea ice. I want to get into his head the larger bearing of the problems which our physical investigations involve. He needs two years here to fully realise these things, and with all his intelligence and energy will produce little unless he has that extended experience.

The sky cleared at noon, and this afternoon I walked over the North Bay to the ice cliffs–such a very beautiful afternoon and evening–the scene bathed in moonlight, so bright and pure as to be almost golden, a very wonderful scene. At such times the Bay seems strangely homely, especially when the eye rests on our camp with the hut and lighted windows.

I am very much impressed with the extraordinary and general cordiality of the relations which exist amongst our people. I do not suppose that a statement of the real truth, namely, that there is no friction at all, will be credited–it is so generally thought that the many rubs of such a life as this are quietly and purposely sunk in oblivion. With me there is no need to draw a veil; there is nothing to cover. There are no strained relations in this hut, and nothing more emphatically evident than the universally amicable spirit which is shown on all occasions.

Such a state of affairs would be delightfully surprising under any conditions, but it is much more so when one remembers the diverse assortment of our company.

This theme is worthy of expansion. To-night Oates, captain in a smart cavalry regiment, has been ‘scrapping’ over chairs and tables with Debenham, a young Australian student.

It is a triumph to have collected such men.

The temperature has been down to -23 deg., the lowest yet recorded here–doubtless we shall soon get lower, for I find an extraordinary difference between this season as far as it has gone and those of 1902-3.

CHAPTER X

In Winter Quarters: Modern Style

_Monday, May_ 15.–The wind has been strong from the north all day–about 30 miles an hour. A bank of stratus cloud about 6000 or 7000 feet (measured by Erebus) has been passing rapidly overhead _towards_ the north; it is nothing new to find the overlying layers of air moving in opposite directions, but it is strange that the phenomenon is so persistent. Simpson has frequently remarked as a great feature of weather conditions here the seeming reluctance of the air to ‘mix’–the fact seems to be the explanation of many curious fluctuations of temperature.

Went for a short walk, but it was not pleasant. Wilson gave an interesting lecture on penguins. He explained the primitive characteristics in the arrangement of feathers on wings and body, the absence of primaries and secondaries or bare tracts; the modification of the muscles of the wings and in the structure of the feet (the metatarsal joint). He pointed out (and the subsequent discussion seemed to support him) that these birds probably branched at a very early stage of bird life–coming pretty directly from the lizard bird Archaeopteryx of the Jurassic age. Fossils of giant penguins of Eocene and Miocene ages show that there has been extremely little development since.

He passed on to the classification and habitat of different genera, nest-making habits, eggs, &c. Then to a brief account of the habits of the Emperors and Adelies, which was of course less novel ground for the old hands.

Of special points of interest I recall his explanation of the desirability of embryonic study of the Emperor to throw further light on the development of the species in the loss of teeth, &c.; and Ponting’s contribution and observation of adult Adelies teaching their young to swim–this point has been obscure. It has been said that the old birds push the young into the water, and, per contra, that they leave them deserted in the rookery–both statements seemed unlikely. It would not be strange if the young Adelie had to learn to swim (it is a well-known requirement of the Northern fur seal–sea bear), but it will be interesting to see in how far the adult birds lay themselves out to instruct their progeny.

During our trip to the ice and sledge journey one of our dogs, Vaida, was especially distinguished for his savage temper and generally uncouth manners. He became a bad wreck with his poor coat at Hut Point, and in this condition I used to massage him; at first the operation was mistrusted and only continued to the accompaniment of much growling, but later he evidently grew to like the warming effect and sidled up to me whenever I came out of the hut, though still with some suspicion. On returning here he seemed to know me at once, and now comes and buries his head in my legs whenever I go out of doors; he allows me to rub him and push him about without the slightest protest and scampers about me as I walk abroad. He is a strange beast–I imagine so unused to kindness that it took him time to appreciate it.

_Tuesday, May_ 16.–The north wind continued all night but dropped this forenoon. Conveniently it became calm at noon and we had a capital game of football. The light is good enough, but not much more than good enough, for this game.

Had some instruction from Wright this morning on the electrical instruments.

Later went into our carbide expenditure with Day: am glad to find it sufficient for two years, but am not making this generally known as there are few things in which economy is less studied than light if regulations allow of waste.

Electrical Instruments

For measuring the ordinary potential gradient we have two self-recording quadrant electrometers. The principle of this instrument is the same as that of the old Kelvin instrument; the clockwork attached to it unrolls a strip of paper wound on a roller; at intervals the needle of the instrument is depressed by an electromagnet and makes a dot on the moving paper. The relative position of these dots forms the record. One of our instruments is adjusted to give only 1/10th the refinement of measurement of the other by means of reduction in the length of the quartz fibre. The object of this is to continue the record in snowstorms, &c., when the potential difference of air and earth is very great. The instruments are kept charged with batteries of small Daniels cells. The clocks are controlled by a master clock.

The instrument available for radio-activity measurements is a modified type of the old gold-leaf electroscope. The measurement is made by the mutual repulsion of quartz fibres acting against a spring–the extent of the repulsion is very clearly shown against a scale magnified by a telescope.

The measurements to be made with instrument are various:

The _ionization of the air_. A length of wire charged with 2000 volts (negative) is exposed to the air for several hours. It is then coiled on a frame and its rate of discharge measured by the electroscope.

The _radio-activity of the various rocks_ of our neighbourhood; this by direct measurement of the rock.

The _conductivity of the air_, that is, the relative movement of ions in the air; by movement of air past charged surface. Rate of absorption of + and – ions is measured, the negative ion travelling faster than the positive.

_Wednesday, May_ 17.–For the first time this season we have a rise of temperature with a southerly wind. The wind force has been about 30 since yesterday evening; the air is fairly full of snow and the temperature has risen to -6 deg. from -18 deg..

I heard one of the dogs barking in the middle of the night, and on inquiry learned that it was one of the ‘Serais,’ [22] that he seemed to have something wrong with his hind leg, and that he had been put under shelter. This morning the poor brute was found dead.

I’m afraid we can place but little reliance on our dog teams and reflect ruefully on the misplaced confidence with which I regarded the provision of our transport. Well, one must suffer for errors of judgment.

This afternoon Wilson held a post-mortem on the dog; he could find no sufficient cause of death. This is the third animal that has died at winter quarters without apparent cause. Wilson, who is nettled, proposes to examine the brain of this animal to-morrow.

Went up the Ramp this morning. There was light enough to see our camp, and it looked homely, as it does from all sides. Somehow we loom larger here than at Cape Armitage. We seem to be more significant. It must be from contrast of size; the larger hills tend to dwarf the petty human element.

To-night the wind has gone back to the north and is now blowing fresh.

This sudden and continued complete change of direction is new to our experience.

Oates has just given us an excellent little lecture on the management of horses.

He explained his plan of feeding our animals ‘soft’ during the winter, and hardening them up during the spring. He pointed out that the horse’s natural food being grass and hay, he would naturally employ a great number of hours in the day filling a stomach of small capacity with food from which he could derive only a small percentage of nutriment.

Hence it is desirable to feed horses often and light. His present routine is as follows:

Morning.–Chaff.

Noon, after exercise.–Snow. Chaff and either oats or oil-cake alternate days.

Evening, 5 P.M.–Snow. Hot bran mash with oil-cake or boiled oats and chaff; finally a small quantity of hay. This sort of food should be causing the animals to put on flesh, but is not preparing them for work. In October he proposes to give ‘hard’ food, all cold, and to increase the exercising hours.

As concerning the food we possess he thinks:

The _chaff_ made of young wheat and hay is doubtful; there does not seem to be any grain with it–and would farmers cut young wheat? There does not seem to be any ‘fat’ in this food, but it is very well for ordinary winter purposes.

N.B.–It seems to me this ought to be inquired into. _Bran_ much discussed, but good because it causes horses to chew the oats with which mixed.

_Oil-cake_, greasy, producing energy–excellent for horses to work on.

_Oats_, of which we have two qualities, also very good working food–our white quality much better than the brown.

Our trainer went on to explain the value of training horses, of getting them ‘balanced’ to pull with less effort. He owns it is very difficult when one is walking horses only for exercise, but thinks something can be done by walking them fast and occasionally making them step backwards.

Oates referred to the deeds that had been done with horses by foreigners in shows and with polo ponies by Englishmen when the animals were trained; it is, he said, a sort of gymnastic training.

The discussion was very instructive and I have only noted the salient points.

_Thursday, May_ 18.–The wind dropped in the night; to-day it is calm, with slight snowfall. We have had an excellent football match–the only outdoor game possible in this light.

I think our winter routine very good, I suppose every leader of a party has thought that, since he has the power of altering it. On the other hand, routine in this connection must take into consideration the facilities of work and play afforded by the preliminary preparations for the expedition. The winter occupations of most of our party depend on the instruments and implements, the clothing and sledging outfit, provided by forethought, and the routine is adapted to these occupations.

The busy winter routine of our party may therefore be excusably held as a subject for self-congratulation.

_Friday, May_ 19.–Wind from the north in the morning, temperature comparatively high (about -6 deg.). We played football during the noon hour–the game gets better as we improve our football condition and skill.

In the afternoon the wind came from the north, dying away again late at night.

In the evening Wright lectured on ‘Ice Problems.’ He had a difficult subject and was nervous. He is young and has never done original work; is only beginning to see the importance of his task.

He started on the crystallisation of ice, and explained with very good illustrations the various forms of crystals, the manner of their growth under different conditions and different temperatures. This was instructive. Passing to the freezing of salt water, he was not very clear. Then on to glaciers and their movements, theories for same and observations in these regions.

There was a good deal of disconnected information–silt bands, crevasses were mentioned. Finally he put the problems of larger aspect.

The upshot of the discussion was a decision to devote another evening to the larger problems such as the Great Ice Barrier and the interior ice sheet. I think I will write the paper to be discussed on this occasion.

I note with much satisfaction that the talks on ice problems and the interest shown in them has had the effect of making Wright devote the whole of his time to them. That may mean a great deal, for he is a hard and conscientious worker.

Atkinson has a new hole for his fish trap in 15 fathoms; yesterday morning he got a record catch of forty-three fish, but oddly enough yesterday evening there were only two caught.

_Saturday, May_ 20.–Blowing hard from the south, with some snow and very cold. Few of us went far; Wilson and Bowers went to the top of the Ramp and found the wind there force 6 to 7, temperature -24 deg.; as a consequence they got frost-bitten. There was lively cheering when they reappeared in this condition, such is the sympathy which is here displayed for affliction; but with Wilson much of the amusement arises from his peculiarly scant headgear and the confessed jealousy of those of us who cannot face the weather with so little face protection.

The wind dropped at night.

_Sunday, May_ 21.–Observed as usual. It blew from the north in the morning. Had an idea to go to Cape Royds this evening, but it was reported that the open water reached to the Barne Glacier, and last night my own observation seemed to confirm this.

This afternoon I started out for the open water. I found the ice solid off the Barne Glacier tongue, but always ahead of me a dark horizon as though I was within a very short distance of its edge. I held on with this appearance still holding up to C. Barne itself and then past that Cape and half way between it and C. Royds. This was far enough to make it evident that the ice was continuous to C. Royds, and has been so for a long time. Under these circumstances the continual appearance of open water to the north is most extraordinary and quite inexplicable.

Have had some very interesting discussions with Wilson, Wright, and Taylor on the ice formations to the west. How to account for the marine organisms found on the weathered glacier ice north of the Koettlitz Glacier? We have been elaborating a theory under which this ice had once a negative buoyancy due to the morainic material on top and in the lower layers of the ice mass, and had subsequently floated when the greater amount of this material had weathered out.

Have arranged to go to C. Royds to-morrow.

The temperatures have sunk very steadily this year; for a long time they hung about zero, then for a considerable interval remained about -10 deg.; now they are down in the minus twenties, with signs of falling (to-day -24 deg.).

Bowers’ meteorological stations have been amusingly named Archibald, Bertram, Clarence–they are entered by the initial letter, but spoken of by full title.

To-night we had a glorious auroral display–quite the most brilliant I have seen. At one time the sky from N.N.W. to S.S.E. as high as the zenith was massed with arches, band, and curtains, always in rapid movement. The waving curtains were especially fascinating–a wave of bright light would start at one end and run along to the other, or a patch of brighter light would spread as if to reinforce the failing light of the curtain.

Auroral Notes

The auroral light is of a palish green colour, but we now see distinctly a red flush preceding the motion of any bright part.

The green ghostly light seems suddenly to spring to life with rosy blushes. There is infinite suggestion in this phenomenon, and in that lies its charm; the suggestion of life, form, colour and movement never less than evanescent, mysterious,–no reality. It is the language of mystic signs and portents–the inspiration of the gods–wholly spiritual–divine signalling. Remindful of superstition, provocative of imagination. Might not the inhabitants of some other world (Mars) controlling mighty forces thus surround our globe with fiery symbols, a golden writing which we have not the key to decipher?

There is argument on the confession of Ponting’s inability to obtain photographs of the aurora. Professor Stormer of Norway seems to have been successful. Simpson made notes of his method, which seems to depend merely on the rapidity of lens and plate. Ponting claims to have greater rapidity in both, yet gets no result even with long exposure. It is not only a question of aurora; the stars are equally reluctant to show themselves on Ponting’s plate. Even with five seconds exposure the stars become short lines of light on the plate of a fixed camera. Stormer’s stars are points and therefore his exposure must have been short, yet there is detail in some of his pictures which it seems impossible could have been got with a short exposure. It is all very puzzling.

_Monday, May_ 22.–Wilson, Bowers, Atkinson, Evans (P.O.), Clissold, and self went to C. Royds with a ‘go cart’ carrying our sleeping-bags, a cooker, and a small quantity of provision.

The ‘go cart’ consists of a framework of steel tubing supported on four bicycle wheels.

The surface of the floes carries 1 to 2 inches of snow, barely covering the salt ice flowers, and for this condition this vehicle of Day’s is excellent. The advantage is that it meets the case where the salt crystals form a heavy frictional surface for wood runners. I’m inclined to think that there are great numbers of cases when wheels would be more efficient than runners on the sea ice.

We reached Cape Royds in 2 1/2 hours, killing an Emperor penguin in the bay beyond C. Barne. This bird was in splendid plumage, the breast reflecting the dim northern light like a mirror.

It was fairly dark when we stumbled over the rocks and dropped on to Shackleton’s Hut. Clissold started the cooking-range, Wilson and I walked over to the Black beach and round back by Blue Lake.

The temperature was down at -31 deg. and the interior of the hut was very cold.

_Tuesday, May_ 23.–We spent the morning mustering the stores within and without the hut, after a cold night which we passed very comfortably in our bags.

We found a good quantity of flour and Danish butter and a fair amount of paraffin, with smaller supplies of assorted articles–the whole sufficient to afford provision for such a party as ours for about six or eight months if well administered. In case of necessity this would undoubtedly be a very useful reserve to fall back upon. These stores are somewhat scattered, and the hut has a dilapidated, comfortless appearance due to its tenantless condition; but even so it seemed to me much less inviting than our old _Discovery_ hut at C. Armitage.

After a cup of cocoa there was nothing to detain us, and we started back, the only useful articles added to our weights being a scrap or two of leather and _five hymn-books_. Hitherto we have been only able to muster seven copies; this increase will improve our Sunday Services.

_Wednesday, May_ 24.–A quiet day with northerly wind; the temperature rose gradually to zero. Having the night duty, did not go out. The moon has gone and there is little to attract one out of doors.

Atkinson gave us an interesting little discourse on parasitology, with a brief account of the life history of some ecto- and some endo-parasites–Nematodes, Trematodes. He pointed out how that in nearly every case there was a secondary host, how in some cases disease was caused, and in others the presence of the parasite was even helpful. He acknowledged the small progress that had been made in this study. He mentioned ankylostomiasis, blood-sucking worms, Bilhartsia (Trematode) attacking bladder (Egypt), Filaria (round tapeworm), Guinea worm, Trichina (pork), and others, pointing to disease caused.

From worms he went to Protozoa-Trypanosomes, sleeping sickness, host tsetse-fly–showed life history comparatively, propagated in secondary host or encysting in primary host–similarly malarial germs spread by Anopheles mosquitoes–all very interesting.

In the discussion following Wilson gave some account of the grouse disease worm, and especially of the interest in finding free living species almost identical; also part of the life of disease worm is free living. Here we approached a point pressed by Nelson concerning the degeneration consequent on adoption of the parasitic habit. All parasites seem to have descended from free living beasts. One asks ‘what is degeneration?’ without receiving a very satisfactory answer. After all, such terms must be empirical.

_Thursday, May_ 25.–It has been blowing from south with heavy gusts and snow, temperature extraordinarily high, -6 deg.. This has been a heavy gale. The weather conditions are certainly very interesting; Simpson has again called attention to the wind in February, March, and April at Cape Evans–the record shows an extraordinary large percentage of gales. It is quite certain that we scarcely got a fraction of the wind on the Barrier and doubtful if we got as much at Hut Point.

_Friday, May_ 26.–A calm and clear day–a nice change from recent weather. It makes an enormous difference to the enjoyment of this life if one is able to get out and stretch one’s legs every day. This morning I went up the Ramp. No sign of open water, so that my fears for a broken highway in the coming season are now at rest. In future gales can only be a temporary annoyance–anxiety as to their result is finally allayed.

This afternoon I searched out ski and ski sticks and went for a short run over the floe. The surface is quite good since the recent snowfall and wind. This is satisfactory, as sledging can now be conducted on ordinary lines, and if convenient our parties can pull on ski. The young ice troubles of April and May have passed away. It is curious that circumstances caused us to miss them altogether during our stay in the _Discovery._

We are living extraordinarily well. At dinner last night we had some excellent thick seal soup, very much like thick hare soup; this was followed by an equally tasty seal steak and kidney pie and a fruit jelly. The smell of frying greeted us on awaking this morning, and at breakfast each of us had two of our nutty little _Notothenia_ fish after our bowl of porridge. These little fish have an extraordinarily sweet taste–bread and butter and marmalade finished the meal. At the midday meal we had bread and butter, cheese, and cake, and to-night I smell mutton in the preparation. Under the circumstances it would be difficult to conceive more appetising repasts or a regime which is likely to produce scorbutic symptoms. I cannot think we shall get scurvy.

Nelson lectured to us to-night, giving a very able little elementary sketch of the objects of the biologist. A fact struck one in his explanation of the rates of elimination. Two of the offspring of two parents alone survive, speaking broadly; this the same of the human species or the ‘ling,’ with 24,000,000 eggs in the roe of each female! He talked much of evolution, adaptation, &c. Mendelism became the most debated point of the discussion; the transmission of characters has a wonderful fascination for the human mind. There was also a point striking deep in the debate on Professor Loeb’s experiments with sea urchins; how far had he succeeded in reproducing the species without the male spermatozoa? Not very far, it seemed, when all was said.

A theme for a pen would be the expansion of interest in polar affairs; compare the interests of a winter spent by the old Arctic voyagers with our own, and look into the causes. The aspect of everything changes as our knowledge expands.

The expansion of human interest in rude surroundings may perhaps best be illustrated by comparisons. It will serve to recall such a simple case as the fact that our ancestors applied the terms horrid, frightful, to mountain crags which in our own day are more justly admired as lofty, grand, and beautiful.

The poetic conception of this natural phenomenon has followed not so much an inherent change of sentiment as the intimacy of wider knowledge and the death of superstitious influence. One is much struck by the importance of realising limits.

_Saturday, May_ 27.–A very unpleasant, cold, windy day. Annoyed with the conditions, so did not go out.

In the evening Bowers gave his lecture on sledging diets. He has shown great courage in undertaking the task, great perseverance in unearthing facts from books, and a considerable practical skill in stringing these together. It is a thankless task to search polar literature for dietary facts and still more difficult to attach due weight to varying statements. Some authors omit discussion of this important item altogether, others fail to note alterations made in practice or additions afforded by circumstances, others again forget to describe the nature of various food stuffs.

Our lecturer was both entertaining and instructive when he dealt with old time rations; but he naturally grew weak in approaching the physiological aspect of the question. He went through with it manfully and with a touch of humour much appreciated; whereas, for instance, he deduced facts from ‘the equivalent of Mr. Joule, a gentleman whose statements he had no reason to doubt.’

Wilson was the mainstay of the subsequent discussion and put all doubtful matters in a clearer light. ‘Increase your fats (carbohydrate)’ is what science seems to say, and practice with conservativism is inclined to step cautiously in response to this urgence. I shall, of course, go into the whole question as thoroughly as available information and experience permits. Meanwhile it is useful to have had a discussion which aired the popular opinions.

Feeling went deepest on the subject of tea versus cocoa; admitting all that can be said concerning stimulation and reaction, I am inclined to see much in favour of tea. Why should not one be mildly stimulated during the marching hours if one can cope with reaction by profounder rest during the hours of inaction?

_Sunday, May_ 28.–Quite an excitement last night. One of the ponies (the grey which I led last year and salved from the floe) either fell or tried to lie down in his stall, his head being lashed up to the stanchions on either side. In this condition he struggled and kicked till his body was twisted right round and his attitude extremely uncomfortable. Very luckily his struggles were heard almost at once, and his head ropes being cut, Oates got him on his feet again. He looked a good deal distressed at the time, but is now quite well again and has been out for his usual exercise.

Held Service as usual.

This afternoon went on ski around the bay and back across. Little or no wind; sky clear, temperature -25 deg.. It was wonderfully mild considering the temperature–this sounds paradoxical, but the sensation of cold does not conform to the thermometer–it is obviously dependent on the wind and less obviously on the humidity of the air and the ice crystals floating in it. I cannot very clearly account for this effect, but as a matter of fact I have certainly felt colder in still air at -10 deg. than I did to-day when the thermometer was down to -25 deg., other conditions apparently equal.

The amazing circumstance is that by no means can we measure the humidity, or indeed the precipitation or evaporation. I have just been discussing with Simpson the insuperable difficulties that stand in the way of experiment in this direction, since cold air can only hold the smallest quantities of moisture, and saturation covers an extremely small range of temperature.

_Monday, May_ 29.–Another beautiful calm day. Went out both before and after the mid-day meal. This morning with Wilson and Bowers towards the thermometer off Inaccessible Island. On the way my companionable dog was heard barking and dimly seen–we went towards him and found that he was worrying a young sea leopard. This is the second found in the Strait this season. We had to secure it as a specimen, but it was sad to have to kill. The long lithe body of this seal makes it almost beautiful in comparison with our stout, bloated Weddells. This poor beast turned swiftly from side to side as we strove to stun it with a blow on the nose. As it turned it gaped its jaws wide, but oddly enough not a sound came forth, not even a hiss.

After lunch a sledge was taken out to secure the prize, which had been photographed by flashlight.

Ponting has been making great advances in flashlight work, and has opened up quite a new field in which artistic results can be obtained in the winter.

Lecture–Japan. To-night Ponting gave us a charming lecture on Japan with wonderful illustrations of his own. He is happiest in his descriptions of the artistic side of the people, with which he is in fullest sympathy. So he took us to see the flower pageants. The joyful festivals of the cherry blossom, the wistaria, the iris and chrysanthemum, the sombre colours of the beech blossom and the paths about the lotus gardens, where mankind meditated in solemn mood. We had pictures, too, of Nikko and its beauties, of Temples and great Buddhas. Then in more touristy strain of volcanoes and their craters, waterfalls and river gorges, tiny tree-clad islets, that feature of Japan–baths and their bathers, Ainos, and so on. His descriptions were well given and we all of us thoroughly enjoyed our evening.

_Tuesday, May_ 30.–Am busy with my physiological investigations. [23] Atkinson reported a sea leopard at the tide crack; it proved to be a crab-eater, young and very active. In curious contrast to the sea leopard of yesterday in snapping round it uttered considerable noise, a gasping throaty growl.

Went out to the outer berg, where there was quite a collection of people, mostly in connection with Ponting, who had brought camera and flashlight.

It was beautifully calm and comparatively warm. It was good to hear the gay chatter and laughter, and see ponies and their leaders come up out of the gloom to add liveliness to the scene. The sky was extraordinarily clear at noon and to the north very bright.

We have had an exceptionally large tidal range during the last three days–it has upset the tide gauge arrangements and brought a little doubt on the method. Day is going into the question, which we thoroughly discussed to-day. Tidal measurements will be worse than useless unless we can be sure of the accuracy of our methods. Pools of salt water have formed over the beach floes in consequence of the high tide, and in the chase of the crab eater to-day very brilliant flashes of phosphorescent light appeared in these pools. We think it due to a small cope-pod. I have just found a reference to the same phenomena in Nordenskioeld’s ‘Vega.’ He, and apparently Bellot before him, noted the phenomenon. An interesting instance of bi-polarity.

Another interesting phenomenon observed to-day was a cirrus cloud lit by sunlight. It was seen by Wilson and Bowers 5 deg. above the northern horizon–the sun is 9 deg. below our horizon, and without refraction we calculate a cloud could be seen which was 12 miles high. Allowing refraction the phenomenon appears very possible.

_Wednesday, May_ 31.–The sky was overcast this morning and the temperature up to -13 deg.. Went out after lunch to ‘Land’s End.’ The surface of snow was sticky for ski, except where drifts were deep. There was an oppressive feel in the air and I got very hot, coming in with head and hands bare.

At 5, from dead calm the wind suddenly sprang up from the south, force 40 miles per hour, and since that it has been blowing a blizzard; wind very gusty, from 20 to 60 miles. I have never known a storm come on so suddenly, and it shows what possibility there is of individuals becoming lost even if they only go a short way from the hut.

To-night Wilson has given us a very interesting lecture on sketching. He started by explaining his methods of rough sketch and written colour record, and explained its suitability to this climate as opposed to coloured chalks, &c.–a very practical method for cold fingers and one that becomes more accurate with practice in observation. His theme then became the extreme importance of accuracy, his mode of expression and explanation frankly Ruskinesque. Don’t put in meaningless lines–every line should be from observation. So with contrast of light and shade–fine shading, subtle distinction, everything–impossible without care, patience, and trained attention.

He raised a smile by generalising failures in sketches of others of our party which had been brought to him for criticism. He pointed out how much had been put in from preconceived notion. ‘He will draw a berg faithfully as it is now and he studies it, but he leaves sea and sky to be put in afterwards, as he thinks they must be like sea and sky everywhere else, and he is content to try and remember how these _should_ be done.’ Nature’s harmonies cannot be guessed at.

He quoted much from Ruskin, leading on a little deeper to ‘Composition,’ paying a hearty tribute to Ponting.

The lecture was delivered in the author’s usual modest strain, but unconsciously it was expressive of himself and his whole-hearted thoroughness. He stands very high in the scale of human beings–how high I scarcely knew till the experience of the past few months.

There is no member of our party so universally esteemed; only to-night I realise how patiently and consistently he has given time and attention to help the efforts of the other sketchers, and so it is all through; he has had a hand in almost every lecture given, and has been consulted in almost every effort which has been made towards the solution of the practical or theoretical problems of our polar world.

The achievement of a great result by patient work is the best possible object lesson for struggling humanity, for the results of genius, however admirable, can rarely be instructive. The chief of the Scientific Staff sets an example which is more potent than any other factor in maintaining that bond of good fellowship which is the marked and beneficent characteristic of our community.

CHAPTER XI

To Midwinter Day

_Thursday, June_ 1.–The wind blew hard all night, gusts arising to 72 m.p.h.; the anemometer choked five times–temperature +9 deg.. It is still blowing this morning. Incidentally we have found that these heavy winds react very conveniently on our ventilating system. A fire is always a good ventilator, ensuring the circulation of inside air and the indraught of fresh air; its defect as a ventilator lies in the low level at which it extracts inside air. Our ventilating system utilises the normal fire draught, but also by suitable holes in the funnelling causes the same draught to extract foul air at higher levels. I think this is the first time such a system has been used. It is a bold step to make holes in the funnelling as obviously any uncertainty of draught might fill the hut with smoke. Since this does not happen with us it follows that there is always strong suction through our stovepipes, and this is achieved by their exceptionally large dimensions and by the length of the outer chimney pipe.

With wind this draught is greatly increased and with high winds the draught would be too great for the stoves if it were not for the relief of the ventilating holes.

In these circumstances, therefore, the rate of extraction of air automatically rises, and since high wind is usually accompanied with marked rise of temperature, the rise occurs at the most convenient season, when the interior of the hut would otherwise tend to become oppressively warm. The practical result of the system is that in spite of the numbers of people living in the hut, the cooking, and the smoking, the inside air is nearly always warm, sweet, and fresh.

There is usually a drawback to the best of arrangements, and I have said ‘nearly’ always. The exceptions in this connection occur when the outside air is calm and warm and the galley fire, as in the early morning, needs to be worked up; it is necessary under these conditions to temporarily close the ventilating holes, and if at this time the cook is intent on preparing our breakfast with a frying-pan we are quickly made aware of his intentions. A combination of this sort is rare and lasts only for a very short time, for directly the fire is aglow the ventilator can be opened again and the relief is almost instantaneous.

This very satisfactory condition of inside air must be a highly important factor in the preservation of health.

I have to-day regularised the pony ‘nicknames’; I must leave it to Drake to pull out the relation to the ‘proper’ names according to our school contracts! [24]

The nicknames are as follows:

James Pigg Keohane
Bones Crean
Michael Clissold
Snatcher Evans (P.O.)
Jehu
China
Christopher Hooper
Victor Bowers
Snippets (windsucker)
Nobby Lashly

_Friday, June_ 2.–The wind still high. The drift ceased at an early hour yesterday; it is difficult to account for the fact. At night the sky cleared; then and this morning we had a fair display of aurora streamers to the N. and a faint arch east. Curiously enough the temperature still remains high, about +7 deg..

The meteorological conditions are very puzzling.

_Saturday, June_ 3.–The wind dropped last night, but at 4 A.M. suddenly sprang up from a dead calm to 30 miles an hour. Almost instantaneously, certainly within the space of one minute, there was a temperature rise of nine degrees. It is the most extraordinary and interesting example of a rise of temperature with a southerly wind that I can remember. It is certainly difficult to account for unless we imagine that during the calm the surface layer of cold air is extremely thin and that there is a steep inverted gradient. When the wind arose the sky overhead was clearer than I ever remember to have seen it, the constellations brilliant, and the Milky Way like a bright auroral streamer.

The wind has continued all day, making it unpleasant out of doors. I went for a walk over the land; it was dark, the rock very black, very little snow lying; old footprints in the soft, sandy soil were filled with snow, showing quite white on a black ground. Have been digging away at food statistics.

Simpson has just given us a discourse, in the ordinary lecture series, on his instruments. Having already described these instruments, there is little to comment upon; he is excellently lucid in his explanations.

As an analogy to the attempt to make a scientific observation when the condition under consideration is affected by the means employed, he rather quaintly cited the impossibility of discovering the length of trousers by bending over to see!

The following are the instruments described:

Features

The outside (bimetallic) thermograph.

The inside thermograph (alcohol)
Alcohol in spiral, small lead pipe–float vessel.

The electrically recording anemometer Cam device with contact on wheel; slowing arrangement, inertia of wheel.

The Dynes anemometer
Parabola on immersed float.

The recording wind vane
Metallic pen.

The magnetometer
Horizontal force measured in two directions–vertical force in one–timing arrangement.

The high and low potential apparatus of the balloon thermograph Spotting arrangement and difference, see _ante_.

Simpson is admirable as a worker, admirable as a scientist, and admirable as a lecturer.

_Sunday, June_ 4.–A calm and beautiful day. The account of this, a typical Sunday, would run as follows: Breakfast. A half-hour or so selecting hymns and preparing for Service whilst the hut is being cleared up. The Service: a hymn; Morning prayer to the Psalms; another hymn; prayers from Communion Service and Litany; a final hymn and our special prayer. Wilson strikes the note on which the hymn is to start and I try to hit it after with doubtful success! After church the men go out with their ponies.

To-day Wilson, Bowers, Cherry-Garrard, Lashly, and I went to start the building of our first ‘igloo.’ There is a good deal of difference of opinion as to the best implement with which to cut snow blocks. Cherry-Garrard had a knife which I designed and Lashly made, Wilson a saw, and Bowers a large trowel. I’m inclined to think the knife will prove most effective, but the others don’t acknowledge it _yet_. As far as one can see at present this knife should have a longer handle and much coarser teeth in the saw edge–perhaps also the blade should be thinner.

We must go on with this hut building till we get good at it. I’m sure it’s going to be a useful art.

We only did three courses of blocks when tea-time arrived, and light was not good enough to proceed after tea.

Sunday afternoon for the men means a ‘stretch of the land.’

I went over the floe on ski. The best possible surface after the late winds as far as Inaccessible Island. Here, and doubtless in most places along the shore, this, the first week of June, may be noted as the date by which the wet, sticky salt crystals become covered and the surface possible for wood runners. Beyond the island the snow is still very thin, barely covering the ice flowers, and the surface is still bad.

There has been quite a small landslide on the S. side of the Island; seven or eight blocks of rock, one or two tons in weight, have dropped on to the floe, an interesting instance of the possibility of transport by sea ice.

Ponting has been out to the bergs photographing by flashlight. As I passed south of the Island with its whole mass between myself and the photographer I saw the flashes of magnesium light, having all the appearance of lightning. The light illuminated the sky and apparently objects at a great distance from the camera. It is evident that there may be very great possibilities in the use of this light for signalling purposes and I propose to have some experiments.

N.B.–Magnesium flashlight as signalling apparatus in the summer.

Another crab-eater seal was secured to-day; he had come up by the bergs.

_Monday, June_ 5.–The wind has been S. all day, sky overcast and air misty with snow crystals. The temperature has gone steadily up and to-night rose to + 16 deg.. Everything seems to threaten a blizzard which cometh not. But what is to be made of this extraordinary high temperature heaven only knows. Went for a walk over the rocks and found it very warm and muggy.

Taylor gave us a paper on the Beardmore Glacier. He has taken pains to work up available information; on the ice side he showed the very gradual gradient as compared with the Ferrar. If crevasses are as plentiful as reported, the motion of glacier must be very considerable. There seem to be three badly crevassed parts where the glacier is constricted and the fall is heavier.

Geologically he explained the rocks found and the problems unsolved. The basement rocks, as to the north, appear to be reddish and grey granites and altered slate (possibly bearing fossils). The Cloudmaker appears to be diorite; Mt. Buckley sedimentary. The suggested formation is of several layers of coal with sandstone above and below; interesting to find if it is so and investigate coal. Wood fossil conifer appears to have come from this–better to get leaves–wrap fossils up for protection.

Mt. Dawson described as pinkish limestone, with a wedge of dark rock; this very doubtful! Limestone is of great interest owing to chance of finding Cambrian fossils (Archeocyathus).

He mentioned the interest of finding here, as in Dry Valley, volcanic cones of recent date (later than the recession of the ice). As points to be looked to in Geology and Physiography:

1. Hope Island shape.

2. Character of wall facets.

3. Type of tributary glacierscliff or curtain, broken.

4. Do tributaries enter ‘at grade’?

5. Lateral gullies pinnacled, &c., shape and size of slope.

6. Do tributaries cut out gullies–empty unoccupied cirques, hangers, &c.

7. Do upland moraines show tesselation?

8. Arrangement of strata, inclusion of.

9. Types of moraines, distance of blocks.

10. Weathering of glaciers. Types of surface. (Thrust mark? Rippled, snow stool, glass house, coral reef, honeycomb, ploughshare, bastions, piecrust.)

11. Amount of water silt bands, stratified, or irregular folded or broken.

12. Cross section, of valleys 35 deg. slopes?

13. Weather slopes debris covered, height to which.

14. Nunataks, height of rounded, height of any angle in profile, erratics.

15. Evidence of order in glacier delta.

Debenham in discussion mentioned usefulness of small chips of rock–many chips from several places are more valuable than few larger specimens.

We had an interesting little discussion.

I must enter a protest against the use made of the word ‘glaciated’ by Geologists and Physiographers.

To them a ‘glaciated land’ is one which appears to have been shaped by former ice action.

The meaning I attach to the phrase, and one which I believe is more commonly current, is that it describes a land at present wholly or partly covered with ice and snow.

I hold the latter is the obvious meaning and the former results from a piracy committed in very recent times.

The alternative terms descriptive of the different meanings are ice covered and ice eroded.

To-day I have been helping the Soldier to design pony rugs; the great thing, I think, is to get something which will completely cover the hindquarters.

_Tuesday, June_ 6.–The temperature has been as high as +19 deg. to-day; the south wind persisted until the evening with clear sky except for fine effects of torn cloud round about the mountain. To-night the moon has emerged from behind the mountain and sails across the cloudless northern sky; the wind has fallen and the scene is glorious.

It is my birthday, a fact I might easily have forgotten, but my kind people did not. At lunch an immense birthday cake made its appearance and we were photographed assembled about it. Clissold had decorated its sugared top with various devices in chocolate and crystallised fruit, flags and photographs of myself.

After my walk I discovered that great preparations were in progress for a special dinner, and when the hour for that meal arrived we sat down to a sumptuous spread with our sledge banners hung about us. Clissold’s especially excellent seal soup, roast mutton and red currant jelly, fruit salad, asparagus and chocolate–such was our menu. For drink we had cider cup, a mystery not yet fathomed, some sherry and a liqueur.

After this luxurious meal everyone was very festive and amiably argumentative. As I write there is a group in the dark room discussing political progress with discussions–another at one corner of the dinner table airing its views on the origin of matter and the probability of its ultimate discovery, and yet another debating military problems. The scraps that reach me from the various groups sometimes piece together in ludicrous fashion. Perhaps these arguments are practically unprofitable, but they give a great deal of pleasure to the participants. It’s delightful to hear the ring of triumph in some voice when the owner imagines he has delivered himself of a well-rounded period or a clinching statement concerning the point under discussion. They are boys, all of them, but such excellent good-natured ones; there has been no sign of sharpness or anger, no jarring note, in all these wordy contests! all end with a laugh.

Nelson has offered Taylor a pair of socks to teach him some geology! This lulls me to sleep!

_Wednesday, June_ 7.–A very beautiful day. In the afternoon went well out over the floe to the south, looking up Nelson at his icehole and picking up Bowers at his thermometer. The surface was polished and beautifully smooth for ski, the scene brightly illuminated with moonlight, the air still and crisp, and the thermometer at -10 deg.. Perfect conditions for a winter walk.

In the evening I read a paper on ‘The Ice Barrier and Inland Ice.’ I have strung together a good many new points and the interest taken in the discussion was very genuine–so keen, in fact, that we did not break up till close on midnight. I am keeping this paper, which makes a very good basis for all future work on these subjects. (See Vol. II.)

Shelters to Iceholes

Time out of number one is coming across rediscoveries. Of such a nature is the building of shelters for iceholes. We knew a good deal about it in the _Discovery_, but unfortunately did not make notes of our experiences. I sketched the above figures for Nelson, and found on going to the hole that the drift accorded with my sketch. The sketches explain themselves. I think wall ‘b’ should be higher than wall ‘a.’

My night on duty. The silent hours passed rapidly and comfortably. To bed 7 A.M.

_Thursday, June_ 8.–Did not turn out till 1 P.M., then with a bad head, an inevitable sequel to a night of vigil. Walked out to and around the bergs, bright moonlight, but clouds rapidly spreading up from south.

Tried the snow knife, which is developing. Debenham and Gran went off to Hut Point this morning; they should return to-morrow.

_Friday, June_ 9.–No wind came with the clouds of yesterday, but the sky has not been clear since they spread over it except for about two hours in the middle of the night when the moonlight was so bright that one might have imagined the day returned.

Otherwise the web of stratus which hangs over us thickens and thins, rises and falls with very bewildering uncertainty. We want theories for these mysterious weather conditions; meanwhile it is annoying to lose the advantages of the moonlight.

This morning had some discussion with Nelson and Wright regarding the action of sea water in melting barrier and sea ice. The discussion was useful to me in drawing attention to the equilibrium of layers of sea water.

In the afternoon I went round the Razor Back Islands on ski, a run of 5 or 6 miles; the surface was good but in places still irregular with the pressures formed when the ice was ‘young.’

The snow is astonishingly soft on the south side of both islands. It is clear that in the heaviest blizzard one could escape the wind altogether by camping to windward of the larger island. One sees more and more clearly what shelter is afforded on the weather side of steep-sided objects.

Passed three seals asleep on the ice. Two others were killed near the bergs.

_Saturday, June_ 10.–The impending blizzard has come; the wind came with a burst at 9.30 this morning.

Simpson spent the night turning over a theory to account for the phenomenon, and delivered himself of it this morning. It seems a good basis for the reference of future observations. He imagines the atmosphere A C in potential equilibrium with large margin of stability, i.e. the difference of temperature between A and C being much less than the adiabatic gradient.

In this condition there is a tendency to cool by radiation until some critical layer, B, reaches its due point. A stratus cloud is thus formed at B; from this moment A B continues to cool, but B C is protected from radiating, whilst heated by radiation from snow and possibly by release of latent heat due to cloud formation.

The condition now rapidly approaches unstable equilibrium, B C tending to rise, A B to descend.

Owing to lack of sun heat the effect will be more rapid in south than north and therefore the upset will commence first in the south. After the first start the upset will rapidly spread north, bringing the blizzard. The facts supporting the theory are the actual formation of a stratus cloud before a blizzard, the snow and warm temperature of the blizzard and its gusty nature.

It is a pretty starting-point, but, of course, there are weak spots.

Atkinson has found a trypanosome in the fish–it has been stained, photographed and drawn–an interesting discovery having regard to the few species that have been found. A trypanosome is the cause of ‘sleeping sickness.’

The blizzard has continued all day with a good deal of drift. I went for a walk, but the conditions were not inviting.

We have begun to consider details of next season’s travelling equipment. The crampons, repair of finnesko with sealskin, and an idea for a double tent have been discussed to-day. P.O. Evans and Lashly are delightfully intelligent in carrying out instructions.

_Sunday, June_ 11.–A fine clear morning, the moon now revolving well aloft and with full face.

For exercise a run on ski to the South Bay in the morning and a dash up the Ramp before dinner. Wind and drift arose in the middle of the day, but it is now nearly calm again.

At our morning service Cherry-Garrard, good fellow, vamped the accompaniment of two hymns; he received encouraging thanks and will cope with all three hymns next Sunday.

Day by day news grows scant in this midwinter season; all events seem to compress into a small record, yet a little reflection shows that this is not the case. For instance I have had at least three important discussions on weather and ice conditions to-day, concerning which many notes might be made, and quite a number of small arrangements have been made.

If a diary can be so inadequate here how difficult must be the task of making a faithful record of a day’s events in ordinary civilised life! I think this is why I have found it so difficult to keep a diary at home.

_Monday, June_ 12.–The weather is not kind to us. There has not been much wind to-day, but the moon has been hid behind stratus cloud. One feels horribly cheated in losing the pleasure of its light. I scarcely know what the Crozier party can do if they don’t get better luck next month.

Debenham and Gran have not yet returned; this is their fifth day of absence.

Bowers and Cherry-Garrard went to Cape Royds this afternoon to stay the night. Taylor and Wright walked there and back after breakfast this morning. They returned shortly after lunch.

Went for a short spin on ski this morning and again this afternoon. This evening Evans has given us a lecture on surveying. He was shy and slow, but very painstaking, taking a deal of trouble in preparing pictures, &c.

I took the opportunity to note hurriedly the few points to which I want attention especially directed. No doubt others will occur to me presently. I think I now understand very well how and why the old surveyors (like Belcher) failed in the early Arctic work.

1. Every officer who takes part in the Southern Journey ought to have in his memory the approximate variation of the compass at various stages of the journey and to know how to apply it to obtain a true course from the compass. The variation changes very slowly so that no great effort of memory is required.

2. He ought to know what the true course is to reach one depot from another.

3. He should be able to take an observation with the theodolite.

4. He should be able to work out a meridian altitude observation.

5. He could advantageously add to his knowledge the ability to work out a longitude observation or an ex-meridian altitude.

6. He should know how to read the sledgemeter.

7. He should note and remember the error of the watch he carries and the rate which is ascertained for it from time to time.

8. He should assist the surveyor by noting the coincidences of objects, the opening out of valleys, the observation of new peaks, &c._19_

_Tuesday, June_ 13.–A very beautiful day. We revelled in the calm clear moonlight; the temperature has fallen to -26 deg.. The surface of the floe perfect for ski–had a run to South Bay in forenoon and was away on a long circuit around Inaccessible Island in the afternoon. In such weather the cold splendour of the scene is beyond description; everything is satisfying, from the deep purple of the starry sky to the gleaming bergs and the sparkle of the crystals under foot.

Some very brilliant patches of aurora over the southern shoulder of the mountain. Observed an exceedingly bright meteor shoot across the sky to the northward.

On my return found Debenham and Gran back from Cape Armitage. They had intended to start back on Sunday, but were prevented by bad weather; they seemed to have had stronger winds than we.

On arrival at the hut they found poor little ‘Mukaka’ coiled up outside the door, looking pitifully thin and weak, but with enough energy to bark at them.

This dog was run over and dragged for a long way under the sledge runners whilst we were landing stores in January (the 7th). He has never been worth much since, but remained lively in spite of all the hardships of sledging work. At Hut Point he looked a miserable object, as the hair refused to grow on his hindquarters. It seemed as though he could scarcely continue in such a condition, and when the party came back to Cape Evans he was allowed to run free alongside the sledge.

On the arrival of the party I especially asked after the little animal and was told by Demetri that he had returned, but later it transpired that this was a mistake–that he had been missed on the journey and had not turned up again later as was supposed.

I learned this fact only a few days ago and had quite given up the hope of ever seeing the poor little beast again. It is extraordinary to realise that this poor, lame, half-clad animal has lived for a whole month by himself. He had blood on his mouth when found, implying the capture of a seal, but how he managed to kill it and then get through its skin is beyond comprehension. Hunger drives hard.

_Wednesday, June_ 14.–Storms are giving us little rest. We found a thin stratus over the sky this morning, foreboding ill. The wind came, as usual with a rush, just after lunch. At first there was much drift–now the drift has gone but the gusts run up to 65 m.p.h.

Had a comfortless stroll around the hut; how rapidly things change when one thinks of the delights of yesterday! Paid a visit to Wright’s ice cave; the pendulum is installed and will soon be ready for observation. Wright anticipates the possibility of difficulty with ice crystals on the agate planes.

He tells me that he has seen some remarkably interesting examples of the growth of ice crystals on the walls of the cave and has observed the same unaccountable confusion of the size of grains in the ice, showing how little history can be gathered from the structure of ice.

This evening Nelson gave us his second biological lecture, starting with a brief reference to the scientific classification of the organism into Kingdom, Phylum, Group, Class, Order, Genus, Species; he stated the justification of a biologist in such an expedition, as being ‘To determine the condition under which organic substances exist in the sea.’

He proceeded to draw divisions between the bottom organisms without power of motion, benthon, the nekton motile life in mid-water, and the plankton or floating life. Then he led very prettily on to the importance of the tiny vegetable organisms as the basis of all life.

In the killer whale may be found a seal, in the seal a fish, in the fish a smaller fish, in the smaller fish a copepod, and in the copepod a diatom. If this be regular feeding throughout, the diatom or vegetable is essentially the base of all.

Light is the essential of vegetable growth or metabolism, and light quickly vanishes in depth of water, so that all ocean life must ultimately depend on the phyto-plankton. To discover the conditions of this life is therefore to go to the root of matters.

At this point came an interlude–descriptive of the various biological implements in use in the ship and on shore. The otter trawl, the Agassiz trawl, the ‘D’ net, and the ordinary dredger.

A word or two on the using of ‘D’ nets and then explanation of sieves for classifying the bottom, its nature causing variation in the organisms living on it.

From this he took us amongst the tow-nets with their beautiful silk fabrics, meshes running 180 to the inch and materials costing 2 guineas the yard–to the German tow-nets for quantitative measurements, the object of the latter and its doubtful accuracy, young fish trawls.

From this to the chemical composition of sea water, the total salt about 3.5 per cent, but variable: the proportions of the various salts do not appear to differ, thus the chlorine test detects the salinity quantitatively. Physically plankton life must depend on this salinity and also on temperature, pressure, light, and movement.

(If plankton only inhabits surface waters, then density, temperatures, &c., of surface waters must be the important factors. Why should biologists strive for deeper layers? Why should not deep sea life be maintained by dead vegetable matter?)

Here again the lecturer branched off into descriptions of water bottles, deep sea thermometers, and current-meters, the which I think have already received some notice in this diary. To what depth light may extend is the difficult problem and we had some speculation, especially in the debate on this question. Simpson suggested that laboratory experiment should easily determine. Atkinson suggested growth of bacteria on a scratched plate. The idea seems to be that vegetable life cannot exist without red rays, which probably do not extend beyond 7 feet or so. Against this is an extraordinary recovery of _Holosphera Firidis_ by German expedition from 2000 fathoms; this seems to have been confirmed. Bowers caused much amusement by demanding to know ‘If the pycnogs (pycnogonids) were more nearly related to the arachnids (spiders) or crustaceans.’ As a matter of fact a very sensible question, but it caused amusement because of its sudden display of long names. Nelson is an exceedingly capable lecturer; he makes his subject very clear and is never too technical.

_Thursday, June_ 15.–Keen cold wind overcast sky till 5.30 P.M. Spent an idle day.

Jimmy Pigg had an attack of colic in the stable this afternoon. He was taken out and doctored on the floe, which seemed to improve matters, but on return to the stable he was off his feed.

This evening the Soldier tells me he has eaten his food, so I hope all be well again.

_Friday, June_ 16.–Overcast again–little wind but also little moonlight. Jimmy Pigg quite recovered.

Went round the bergs in the afternoon. A great deal of ice has fallen from the irregular ones, showing that a great deal of weathering of bergs goes on during the winter and hence that the life of a berg is very limited, even if it remains in the high latitudes.

To-night Debenham lectured on volcanoes. His matter is very good, but his voice a little monotonous, so that there were signs of slumber in the audience, but all woke up for a warm and amusing discussion succeeding the lecture.

The lecturer first showed a world chart showing distribution of volcanoes, showing general tendency of eruptive explosions to occur in lines. After following these lines in other parts of the world he showed difficulty of finding symmetrical linear distribution near McMurdo Sound. He pointed out incidentally the important inference which could be drawn from the discovery of altered sandstones in the Erebus region. He went to the shapes of volcanoes:

The massive type formed by very fluid lavas–Mauna Loa (Hawaii), Vesuvius, examples.

The more perfect cones formed by ash talus–Fujiama, Discovery.

The explosive type with parasitic cones–Erebus, Morning, Etna.

Fissure eruption–historic only in Iceland, but best prehistoric examples Deccan (India) and Oregon (U.S.).

There is small ground for supposing relation between adjacent volcanoes–activity in one is rarely accompanied by activity in the other. It seems most likely that vent tubes are entirely separate.

_Products of volcanoes_.–The lecturer mentioned the escape of quantities of free hydrogen–there was some discussion on this point afterwards; that water is broken up is easily understood, but what becomes of the oxygen? Simpson suggests the presence of much oxidizable material.

CO_2 as a noxious gas also mentioned and discussed–causes mythical ‘upas’ tree–sulphurous fumes attend final stages.

Practically little or no heat escapes through sides of a volcano.

There was argument over physical conditions influencing explosions–especially as to barometric influence. There was a good deal of disjointed information on lavas, ropy or rapid flowing and viscous–also on spatter cones and caverns.

In all cases lavas cool slowly–heat has been found close to the surface after 87 years. On Etna there is lava over ice. The lecturer finally reviewed the volcanicity of our own neighbourhood. He described various vents of Erebus, thinks Castle Rock a ‘plug’–here some discussion–Observation Hill part of old volcano, nothing in common with Crater Hill. Inaccessible Island seems to have no connection with Erebus.

Finally we had a few words on the origin of volcanicity and afterwards some discussion on an old point–the relation to the sea. Why are volcanoes close to sea? Debenham thinks not cause and effect, but two effects resulting from same cause.

Great argument as to whether effect of barometric changes on Erebus vapour can be observed. Not much was said about the theory of volcanoes, but Debenham touched on American theories–the melting out from internal magma.

There was nothing much to catch hold of throughout, but discussion of such a subject sorts one’s ideas.

_Saturday, June_ 17.–Northerly wind, temperature changeable, dropping to -16 deg..

Wind doubtful in the afternoon. Moon still obscured–it is very trying. Feeling dull in spirit to-day.

_Sunday, June_ 18.–Another blizzard–the weather is distressing. It ought to settle down soon, but unfortunately the moon is passing.

Held the usual Morning Service. Hymns not quite successful to-day.

To-night Atkinson has taken the usual monthly measurement. I don’t think there has been much change.

_Monday, June_ 19.–A pleasant change to find the air calm and the sky clear–temperature down to -28 deg.. At 1.30 the moon vanished behind the western mountains, after which, in spite of the clear sky, it was very dark on the floe. Went out on ski across the bay, then round about the cape, and so home, facing a keen northerly wind on return.

Atkinson is making a new fish trap hole; from one cause and another, the breaking of the trap, and the freezing of the hole, no catch has been made for some time. I don’t think we shall get good catches during the dark season, but Atkinson’s own requirements are small, and the fish, though nice enough, are not such a luxury as to be greatly missed from our ‘menu.’

Our daily routine has possessed a settled regularity for a long time. Clissold is up about 7 A.M. to start the breakfast. At 7.30 Hooper starts sweeping the floor and setting the table. Between 8 and 8.30 the men are out and about, fetching ice for melting, &c. Anton is off to feed the ponies, Demetri to see the dogs; Hooper bursts on the slumberers with repeated announcements of the time, usually a quarter of an hour ahead of the clock. There is a stretching of limbs and an interchange of morning greetings, garnished with sleepy humour. Wilson and Bowers meet in a state of nature beside a washing basin filled with snow and proceed to rub glistening limbs with this chilling substance. A little later with less hardihood some others may be seen making the most of a meagre allowance of water. Soon after 8.30 I manage to drag myself from a very comfortable bed and make my toilet with a bare pint of water. By about ten minutes to 9 my clothes are on, my bed is made, and I sit down to my bowl of porridge; most of the others are gathered about the table by this time, but there are a few laggards who run the nine o’clock rule very close. The rule is instituted to prevent delay in the day’s work, and it has needed a little pressure to keep one or two up to its observance. By 9.20 breakfast is finished, and before the half-hour has struck the table has been cleared. From 9.30 to 1.30 the men are steadily employed on a programme of preparation for sledging, which seems likely to occupy the greater part of the winter. The repair of sleeping-bags and the alteration of tents have already been done, but there are many other tasks uncompleted or not yet begun, such as the manufacture of provision bags, crampons, sealskin soles, pony clothes, &c.

Hooper has another good sweep up the hut after breakfast, washes the mess traps, and generally tidies things. I think it a good thing that in these matters the officers need not wait on themselves; it gives long unbroken days of scientific work and must, therefore, be an economy of brain in the long run.

We meet for our mid-day meal at 1.30 or 1.45, and spend a very cheerful half-hour over it. Afterwards the ponies are exercised, weather permitting; this employs all the men and a few of the officers for an hour or more–the rest of us generally take exercise in some form at the same time. After this the officers go on steadily with their work, whilst the men do odd jobs to while away the time. The evening meal, our dinner, comes at 6.30, and is finished within the hour. Afterwards people read, write, or play games, or occasionally finish some piece of work. The gramophone is usually started by some kindly disposed person, and on three nights of the week the lectures to which I have referred are given. These lectures still command full audiences and lively discussions.

At 11 P.M. the acetylene lights are put out, and those who wish to remain up or to read in bed must depend on candle-light. The majority of candles are extinguished by midnight, and the night watchman alone remains awake to keep his vigil by the light of an oil lamp.

Day after day passes in this fashion. It is not a very active life perhaps, but certainly not an idle one. Few of us sleep more than eight hours out of the twenty-four.

On Saturday afternoon or Sunday morning some extra bathing takes place; chins are shaven, and perhaps clean garments donned. Such signs, with the regular Service on Sunday, mark the passage of the weeks.

To-night Day has given us a lecture on his motor sledge. He seems very hopeful of success, but I fear is rather more sanguine in temperament than his sledge is reliable in action. I wish I could have more confidence in his preparations, as he is certainly a delightful companion.

_Tuesday, June_ 20.–Last night the temperature fell to -36 deg., the lowest we have had this year. On the Ramp the minimum was -31 deg., not the first indication of a reversed temperature gradient. We have had a calm day, as is usual with a low thermometer.

It was very beautiful out of doors this morning; as the crescent moon was sinking in the west, Erebus showed a heavy vapour cloud, showing that the quantity is affected by temperature rather than pressure.

I’m glad to have had a good run on ski.

The Cape Crozier party are preparing for departure, and heads have been put together to provide as much comfort as the strenuous circumstances will permit. I came across a hint as to the value of a double tent in Sverdrup’s book, ‘New Land,’ and (P.O.) Evans has made a lining for one of the tents; it is secured on the inner side of the poles and provides an air space inside the tent. I think it is going to be a great success, and that it will go far to obviate the necessity of considering the question of snow huts–though we shall continue our efforts in this direction also.

Another new departure is the decision to carry eiderdown sleeping-bags inside the reindeer ones.

With such an arrangement the early part of the journey is bound to be comfortable, but when the bags get iced difficulties are pretty certain to arise.

Day has been devoting his energies to the creation of a blubber stove, much assisted of course by the experience gained at Hut Point.

The blubber is placed in an annular vessel, A. The oil from it passes through a pipe, B, and spreads out on the surface of a plate, C, with a containing flange; _d d_ are raised points which serve as heat conductors; _e e_ is a tin chimney for flame with air holes at its base.

To start the stove the plate C must be warmed with spirit lamp or primus, but when the blubber oil is well alight its heat is quite sufficient to melt the blubber in And keep up the oil supply–the heat gradually rises until the oil issues from B in a vaporised condition, when, of course, the heat given off by the stove is intense.

This stove was got going this morning in five minutes in the outer temperature with the blubber hard frozen. It will make a great
