berg the pressure makes all sorts of quaint noises. We heard tapping as from a hammer, grunts, groans and squeaks, electric trams running, birds singing, kettles boiling noisily, and an occasional swish as a large piece of ice, released from pressure, suddenly jumped or turned over. We noticed all sorts of quaint effects, such as huge bubbles or domes of ice, 40 ft. across and 4 or 5 ft. high. Large sinuous pancake-sheets were spread over the floe in places, and in one spot we counted five such sheets, each about 2½ in. thick, imbricated under one another. They look as though made of barley-sugar and are very slippery.”
The noon position on the 14th was lat. 76° 54´ S., long. 36° 10´ W. The land was visible faintly to the south-east, distant about 36 miles. A few small leads could be seen from the ship, but the ice was firm in our neighbourhood. The drift of the Endurance was still towards the north-west.
I had the boilers blown down on the 15th, and the consumption of 2 cwt. of coal per day to keep the boilers from freezing then ceased. The bunkers still contained 52 tons of coal, and the daily consumption in the stoves was about 2½ cwt. There would not be much coal left for steaming purposes in the spring, but I anticipated eking out the supply with blubber. A moderate gale from the north-east on the 17th brought fine, penetrating snow. The weather cleared in the evening, and a beautiful crimson sunset held our eyes. At the same time the ice-cliffs of the land were thrown up in the sky by mirage, with an apparent reflection in open water, though the land itself could not be seen definitely. The effect was repeated in an exaggerated form on the following day, when the ice-cliffs were thrown up above the horizon in double and treble parallel lines, some inverted. The mirage was due probably to lanes of open water near the land. The water would be about 30° warmer than the air and would cause warmed strata to ascend. A sounding gave 606 fathoms, with a bottom of glacial mud. Six days later, on the 24th, the depth was 419 fathoms. We were drifting steadily, and the constant movement, coupled with the appearance of lanes near the land, convinced me that we must stay by the ship till she got clear. I had considered the possibility of making a landing across the ice in the spring, but the hazards of such an undertaking would be too great.
The training of the dogs in sledge teams was making progress. The orders used by the drivers were “Mush” (Go on), “Gee” (Right), “Haw” (Left), and “Whoa” (Stop). These are the words that the Canadian drivers long ago adopted, borrowing them originally from England. There were many fights at first, until the dogs learned their positions and their duties, but as days passed drivers and teams became efficient. Each team had its leader, and efficiency depended largely on the willingness and ability of this dog to punish skulking and disobedience. We learned not to interfere unless the disciplinary measures threatened to have a fatal termination. The drivers could sit on the sledge and jog along at ease if they chose. But the prevailing minus temperatures made riding unpopular, and the men preferred usually to run or walk alongside the teams. We were still losing dogs through sickness, due to stomach and intestinal worms.
Dredging for specimens at various depths was one of the duties during these days. The dredge and several hundred fathoms of wire line made a heavy load, far beyond the unaided strength of the scientists. On the 23rd, for example, we put down a 2 ft. dredge and 650 fathoms of wire. The dredge was hove in four hours later and brought much glacial mud, several pebbles and rock fragments, three sponges, some worms, brachiapods, and foraminiferae. The mud was troublesome. It was heavy to lift, and as it froze rapidly when brought to the surface, the recovery of the specimens embedded in it was difficult. A haul made on the 26th brought a prize for the geologist in the form of a lump of sandstone weighing 75 lbs., a piece of fossiliferous limestone, a fragment of striated shale, sandstone-grit, and some pebbles. Hauling in the dredge by hand was severe work, and on the 24th we used the Girling tractor-motor, which brought in 500 fathoms of line in thirty minutes, including stops. One stop was due to water having run over the friction gear and frozen. It was a day or two later that we heard a great yell from the floe and found Clark dancing about and shouting Scottish war-cries. He had secured his first complete specimen of an Antarctic fish, apparently a new species.
Mirages were frequent. Barrier-cliffs appeared all around us on the 29th, even in places where we knew there was deep water.
“Bergs and pack are thrown up in the sky and distorted into the most fantastic shapes. They climb, trembling, upwards, spreading out into long lines at different levels, then contract and fall down, leaving nothing but an uncertain, wavering smudge which comes and goes. Presently the smudge swells and grows, taking shape until it presents the perfect inverted reflection of a berg on the horizon, the shadow hovering over the substance. More smudges appear at different points on the horizon. These spread out into long lines till they meet, and we are girdled by lines of shining snow-cliffs, laved at their bases by waters of illusion in which they appear to be faithfully reflected. So the shadows come and go silently, melting away finally as the sun declines to the west. We seem to be drifting helplessly in a strange world of unreality. It is reassuring to feel the ship beneath one’s feet and to look down at the familiar line of kennels and igloos on the solid floe.”
The floe was not so solid as it appeared. We had reminders occasionally that the greedy sea was very close, and that the floe was but a treacherous friend, which might open suddenly beneath us. Towards the end of the month I had our store of seal meat and blubber brought aboard. The depth as recorded by a sounding on the last day of March was 256 fathoms. The continuous shoaling from 606 fathoms in a drift of 39 miles N. 26° W. in thirty days was interesting. The sea shoaled as we went north, either to east or to west, and the fact suggested that the contour-lines ran east and west, roughly. Our total drift between January 19, when the ship was frozen in, and March 31, a period of seventy-one days, had been 95 miles in a N. 80° W. direction. The icebergs around us had not changed their relative positions.
The sun sank lower in the sky, the temperatures became lower, and the Endurance felt the grip of the icy hand of winter. Two north-easterly gales in the early part of April assisted to consolidate the pack. The young ice was thickening rapidly, and though leads were visible occasionally from the ship, no opening of a considerable size appeared in our neighbourhood. In the early morning of April 1 we listened again for the wireless signals from Port Stanley. The crew had lashed three 20-ft. rickers to the mast-heads in order to increase the spread of our aerials, but still we failed to hear anything. The rickers had to come down subsequently, since we found that the gear could not carry the accumulating weight of rime. Soundings proved that the sea continued to shoal as the Endurance drifted to the north-west. The depth on April 2 was 262 fathoms, with a bottom of glacial mud. Four weeks later a sounding gave 172 fathoms. The presence of grit in the bottom samples towards the end of the month suggested that we were approaching land again.
The month was not uneventful. During the night of the 3rd we heard the ice grinding to the eastward, and in the morning we saw that young ice was rafted 8 to 10 ft. high in places. This was the first murmur of the danger that was to reach menacing proportions in later months. The ice was heard grinding and creaking during the 4th and the ship vibrated slightly. The movement of the floe was sufficiently pronounced to interfere with the magnetic work. I gave orders that accumulations of snow, ice, and rubbish alongside the Endurance should be shovelled away, so that in case of pressure there would be no weight against the topsides to check the ship rising above the ice. All hands were busy with pick and shovel during the day, and moved many tons of material. Again, on the 9th, there were signs of pressure. Young ice was piled up to a height of 11 ft. astern of the ship, and the old floe was cracked in places. The movement was not serious, but I realized that it might be the beginning of trouble for the Expedition. We brought certain stores aboard and provided space on deck for the dogs in case they had to be removed from the floe at short notice. We had run a 500-fathom steel wire round the ship, snow-huts, and kennels, with a loop out to the lead ahead, where the dredge was used. This wire was supported on ice-pillars, and it served as a guide in bad weather when the view was obscured by driving snow and a man might have lost himself altogether. I had this wire cut in five places, since otherwise it might have been dragged across our section of the floe with damaging effect in the event of the ice splitting suddenly.
The dogs had been divided into six teams of nine dogs each. Wild, Crean, Macklin, McIlroy, Marston, and Hurley each had charge of a team, and were fully responsible for the exercising, training, and feeding of their own dogs. They called in one of the
