Ten days passed away much in the manner I have described. We then got into comparatively clear water for a few hours, during which time the other ships joined us. As there was no wind, we had to tow the ship ahead in the boats, so that there was no cessation of our labours. "Well," I exclaimed to old David, "I suppose after all this we shall soon get into an open sea again." "Don't be too sure of that, or of anything else, lad," he answered. "We have not yet got into the thick of it, let me tell you." I found that his words were too true. The boats had been hoisted in, for a breeze had sprung up, and we were progressing favourably, when we came to some large floes. The openings between them were wide, and without hesitation we proceeded through them. On a sudden these vast masses were seen in motion, slowly moving round and round, without any apparent cause. The captain hailed from the crow's-nest, ordering the ice-saws to be got ready, and the ship to be steered towards one of the largest floes close on the larboard bow. The sails were clewed up, and the ice-claws being carried out, the ship was hauled close up to it; and while the captain and carpenters were measuring out a dock, a party, of which I was one, set to work with the saws. There was no time to be lost. A moment too late, and our stout ship might be cracked like a walnut, and we might all be cast homeless on the bleak expanse of ice to perish miserably. The floes were approaching rapidly, grinding and crushing against one another, now overlapping each other; or, like wild horses fighting desperately, rearing up against each other, and with terrific roar breaking into huge fragments. "Bear a hand, my lads; bear a hand, that's good fellows. We'll not be nipped this time if we can help it," sung out the officers in a cheering tone to encourage us, though the anxious looks they cast towards the approaching masses showed that their confidence was more assumed than real. Whatever we thought, we worked and sung away as if we were engaged in one of the ordinary occupations of life, and that, though we were in a hurry, there was no danger to be apprehended. The dock was cut long-wise into the ice the length of the ship, which was to be hauled in stern first. As there was every appearance of a heavy pressure, the ice at the inner part of the dock was cut into diamond-shaped pieces, so that, when the approaching floe should press on the bows, the vessel might sustain the pressure with greater ease, by either driving the pieces on to the ice, or rising over them. The crews of all the other ships were engaged in the same way, but, as may be supposed, we had little time to attend to them. Our captain was engaged in superintending our operations; but I saw him cast many an anxious glance towards our advancing foes.
