 above sea-level. After a hot meal all hands, except the watchman, turned in. Every one was in need of rest after the troubles of the previous night and the unaccustomed strain of the last thirty-six hours at the oars. The berg appeared well able to withstand the battering of the sea, and too deep and massive to be seriously affected by the swell; but it was not as safe as it looked. About midnight the watchman called me and showed me that the heavy north-westerly swell was undermining the ice. A great piece had broken off within eight feet of my tent. We made what inspection was possible in the darkness, and found that on the westward side of the berg the thick snow covering was yielding rapidly to the attacks of the sea. An ice-foot had formed just under the surface of the water. I decided that there was no immediate danger and did not call the men. The north-westerly wind strengthened during the night.

The morning of April 11 was overcast and misty. There was a haze on the horizon, and daylight showed that the pack had closed round our berg, making it impossible in the heavy swell to launch the boats. We could see no sign of the water. Numerous whales and killers were blowing between the floes, and Cape pigeons, petrels, and fulmars were circling round our berg. The scene from our camp as the daylight brightened was magnificent beyond description, though I must admit that we viewed it with anxiety. Heaving hills of pack and floe were sweeping towards us in long undulations, later to be broken here and there by the dark lines that indicated open water. As each swell lifted around our rapidly dissolving berg it drove floe-ice on to the ice-foot, shearing off more of the top snow-covering and reducing the size of our camp. When the floes retreated to attack again the water swirled over the ice-foot, which was rapidly increasing in width. The launching of the boats under such conditions would be difficult. Time after time, so often that a track was formed, Worsley, Wild, and I, climbed to the highest point of the berg and stared out to the horizon in search of a break in the pack. After long hours had dragged past, far away on the lift of the swell there appeared a dark break in the tossing field of ice. Aeons seemed
