I was greatly pleased with the dogs, which were tethered about the ship in the most comfortable positions we could find for them. They were in excellent condition, and I felt that the Expedition had the right tractive-power. They were big, sturdy animals, chosen for endurance and strength, and if they were as keen to pull our sledges as they were now to fight one another all would be well. The men in charge of the dogs were doing their work enthusiastically, and the eagerness they showed to study the natures and habits of their charges gave promise of efficient handling and good work later on.
During December 6 the Endurance made good progress on a south-easterly course. The northerly breeze had freshened during the night and had brought up a high following sea. The weather was hazy, and we passed two bergs, several growlers, and numerous lumps of ice. Staff and crew were settling down to the routine. Bird life was plentiful, and we noticed Cape pigeons, whale-birds, terns, mollymauks, nellies, sooty, and wandering albatrosses in the neighbourhood of the ship. The course was laid for the passage between Sanders Island and Candlemas Volcano. December 7 brought the first check. At six o’clock that morning the sea, which had been green in colour all the previous day, changed suddenly to a deep indigo. The ship was behaving well in a rough sea, and some members of the scientific staff were transferring to the bunkers the coal we had stowed on deck. Sanders Island and Candlemas were sighted early in the afternoon, and the Endurance passed between them at 6 p.m. Worsley’s observations indicated that Sanders Island was, roughly, three miles east and five miles north of the charted position. Large numbers of bergs, mostly tabular in form, lay to the west of the islands, and we noticed that many of them were yellow with diatoms. One berg had large patches of red-brown soil down its sides. The presence of so many bergs was ominous, and immediately after passing between the islands we encountered stream-ice. All sail was taken in and we proceeded slowly under steam. Two hours later, fifteen miles north-east of Sanders Island, the Endurance was confronted by a belt of heavy pack-ice, half a mile broad and extending north and south. There was clear water beyond, but the heavy south-westerly swell made the pack impenetrable in our neighbourhood. This was disconcerting. The noon latitude had been 57° 26´ S., and I had not expected to find pack-ice nearly so far north, though the whalers had reported pack-ice right up to South Thule.
The situation became dangerous that night. We pushed into the pack in the hope of reaching open water beyond, and found ourselves after dark in a pool which was growing smaller and smaller. The ice was grinding around the ship in the heavy swell, and I watched with some anxiety for any indication of a change of wind to the east, since a breeze from that quarter would have driven us towards the land. Worsley and I were on deck all night, dodging the pack. At 3 a.m. we ran south, taking advantage of some openings that had appeared, but met heavy rafted pack-ice, evidently old; some of it had been subjected to severe pressure. Then we steamed north-west and saw open water to the north-east. I put the Endurance’s head for the opening, and, steaming at full speed, we got clear. Then we went east in the hope of getting better ice, and five hours later, after some dodging, we rounded the pack and were able to set sail once more. This initial tussle with the pack had been exciting at times. Pieces of ice and bergs of all sizes were heaving and jostling against each other in the heavy south-westerly swell. In spite of all our care the Endurance struck large lumps stem on, but the engines were stopped in time and no harm was done. The scene and sounds throughout the day were very fine. The swell was dashing against the sides of huge bergs and leaping right to the top of their icy cliffs. Sanders Island lay to the south, with a few rocky faces peering through the misty, swirling clouds that swathed it most of the time, the booming of the sea running into ice-caverns, the swishing break of the swell on the loose pack, and the graceful bowing and undulating of the inner pack to the steeply rolling swell, which here was robbed of its break by the masses of ice to windward.
We skirted the northern edge of the pack in clear weather with a light south-westerly breeze and an overcast sky. The bergs were numerous. During the morning of December 9 an easterly breeze brought hazy weather with snow, and at 4.30 p.m. we encountered the edge of pack-ice in lat. 58° 27´ S., long. 22° 08´ W. It was one-year-old ice interspersed with older pack, all heavily snow-covered and lying west-south-west to east-north-east. We entered the pack at 5 p.m., but could not make progress, and cleared it again at 7.40 p.m. Then we steered east-north-east and spent the rest of the night rounding the pack. During the day we had seen adelie and ringed penguins, also several humpback and finner whales. An ice-blink to the westward indicated the presence of pack in that direction. After rounding the pack we steered S. 40° E., and at noon on the 10th had reached lat. 58° 28´ S., long. 20° 28´ W. Observations showed the compass variation to be 1½° less than the chart recorded. I kept the Endurance on the course till midnight, when we entered loose open ice about ninety miles south-east of our noon position. This ice proved to fringe the pack, and progress became slow. There was a long easterly swell with a light northerly breeze, and the weather was clear and fine. Numerous bergs lay outside the pack.
The Endurance steamed through loose open ice till 8 a.m. on the 11th, when we entered the pack in lat. 59° 46´ S., long. 18° 22´ W. We could have gone farther east, but the pack extended far in that direction, and an effort to circle it might have involved a lot of northing. I did not wish to lose the benefit of the original southing. The extra miles would not have mattered to a ship with larger coal capacity than the Endurance possessed, but we could not afford to sacrifice miles unnecessarily. The pack was loose and did not present great difficulties at this stage. The foresail was set in order to take advantage of the northerly breeze. The ship was in contact with the ice occasionally and received some heavy blows. Once or twice she was brought up all standing against solid pieces, but no harm was done. The chief concern was to protect the propeller and rudder. If a collision seemed to be inevitable the officer in charge would order “slow” or “half speed” with the engines, and put the helm over so as to strike floe a glancing blow. Then the helm would be put over towards the ice with the object of throwing the propeller clear of it, and the ship would forge ahead again. Worsley, Wild, and I, with three officers, kept three watches while we were working through the pack, so that we had two officers on deck all the time. The carpenter had rigged a six-foot wooden semaphore on the bridge to enable the navigating officer to give the seamen or scientists at the wheel the direction and the exact amount of helm required. This device saved time, as well as the effort of shouting. We were pushing through this loose pack all day, and the view from the crow’s-nest gave no promise of improved conditions ahead. A Weddell seal and a crab-eater seal were noticed on the floes, but we did not pause to secure fresh meat. It was important that we should make progress towards our goal as rapidly as possible, and there was reason to fear that we should have plenty of time to spare later on if the ice conditions continued to increase in severity.
