During the afternoon three adelie penguins approached the ship across the floe while Hussey was discoursing sweet music on the banjo. The solemn-looking little birds appeared to appreciate It’s a Long Way to Tipperary, but they fled in horror when Hussey treated them to a little of the music that comes from Scotland.

Adelies on Paulet Island by Allan Hansen, 2009

The quaint little penguins found the ship a cause of much apparent excitement and provided a lot of amusement aboard. One of the standing jokes was that all the adelies on the floe seemed to know Clark, and when he was at the wheel rushed along as fast as their legs could carry them, yelling out “Clark! Clark!” and apparently very indignant and perturbed that he never waited for them or even answered them.

When the way was barred by a floe of moderate thickness we would drive the ship at half speed against it, stopping the engines just before the impact. At the first blow the Endurance would cut a V-shaped nick in the face of the floe, the slope of her cutwater often causing her bows to rise till nearly clear of the water, when she would slide backwards, rolling slightly. Watching carefully that loose lumps of ice did not damage the propeller, we would reverse the engines and back the ship off 200 to 300 yards. She would then be driven full speed into the V, taking care to hit the center accurately. The operation would be repeated until a short dock was cut, into which the ship, acting as a large wedge, was driven. At about the fourth attempt, if it was to succeed at all, the floe would yield. A black, sinuous line, as though pen-drawn on white paper, would appear ahead, boradening as the eye traced it back to the ship. Presently it would be broad enough to receive her, and we would forge ahead. Under the bows and alongside, great slabs of ice were being turned over and slid back on the floe, or driven down and under the ice and ship. In this way the Endurance would split a 2-ft. to 3-ft. floe a square mile in extent. Occasionally the floe, although cracked across, would be so held by other floes that it would refuse to open wide, and so gradually would bring the ship to a standstill. We would then go astern for some distance and again drive her full speed into the crack, till finally the floe would yield to the repeated onslaughts.

But the Weddell Sea was notoriously inhospitable, and already we knew that its sternest face was turned towards us. All the conditions in the Weddell Sea are unfavorable from the navigator’s point of view. The winds are comparatively light, and consequently new ice can form even in the summertime. The absence of strong winds has the additional effect of allowing the ice to accumulate in masses, undisturbed. Then great quantities of ice sweep along the coast from the east under the influence of the prevailing current, and fill up the bight of the Weddell Sea as they move north in a great semicircle. Some of this ice doubtless describes almost a complete circle, and is held up eventually, in bad seasons, against the South Sandwich Islands. The strong currents, pressing the ice masses against the coasts, create heavier pressure than is found in any other part of the Antarctic. The pressure must be at least as severe as the pressure experienced in the congested North Polar basin, and I am inclined to think that a comparison would be to the advantage of the Arctic. All these considerations naturally had a bearing upon our immediate problem, the penetration of the pack and the finding of a safe harbor on the continental coast.
