After Andrew had heard all of us express our opinions, he resolved to quit the floe and retreat to the main ice. "We'll stay on the edge of it for one day, or two if you wish it, and we'll keep a bright look-out for a ship; but it's my opinion that the last has passed, and that we had better make up our minds to winter on shore. The sooner we begin our preparations the better chance we have of weathering out the time." This plan being agreed to, two hands were sent to unstep the flagstaff and bring it forward, while the rest of us dismantled our hut, and dragged the boat to the edge of the floe nearest the shore. It was time that we should be off, for the channel had already widened to half a mile. Though the water was perfectly smooth, the boat, with all our party and our stores, had as much in her as she could conveniently carry. A quarter of an hour served to carry us across, when we again hauled our boat up; and choosing the highest hummock in the neighbourhood, we again erected our flagstaff. Before, however, we began to build a hut, we examined the condition of the ice round us, to ascertain whether there was a probability of another floe breaking away with us. On finding it, according to the opinion of the old hands, perfectly secure, we put up a tent in the same manner as the last, though of rather a larger size. This done, we cooked and ate the first food we had tasted that day, for we had been too busy all the morning to think of eating. Andrew then urged us to make diligent search for any of the oil-giving fish which we could catch. Accordingly, armed with our harpoons and lances, we set out, leaving one hand to guard the boat and to keep a look-out for a passing sail. We first kept along the edge of the ice; but meeting with no success, we turned towards the land to look for any pools which might exist in the ice. After looking about for some time, we came to one nearly the eighth of a mile across. In it were a shoal of narwhals or sea-unicorns, every now and then rising above the water to breathe, and then diving down again in search of prey. Could we have brought the boat so far, we should have had no difficulty in killing them, but now it depended how near they would rise to the edge. It was tantalising to watch them and not to be able to get hold of any. We divided into three parties, for we had as many harpoons; and at last one rose within reach of David's weapon. He launched it forth, and struck the fish in the neck. Down it dived rapidly; but it soon had to return to the surface, when we hauled it towards the edge and despatched it quickly with our lances, after which we hauled it upon the ice. In the same manner another was afterwards killed. These were indeed prizes; for, though not so valuable as the seals, their flesh and oil were most welcome.
