“Though I had seen vast bodies of ice from Spitzbergen to 150° west longitude under various aspects, some beautiful, and all more or less awe-inspiring, I had never witnessed, nor even imagined, anything so fearfully magnificent as the moving towers and ramparts that now frowned on every side. Had the still extensive pieces of which the floe was formed split and divided like those further off, the effect would have been far less injurious to the ship; but though cracked and rent, the parts, from some inexplicable cause, closed again for a time, and drove with accelerated and almost irresistible force against the defenceless vessel. In the forenoon the other boats were hoisted higher up, to save them from damage in the event of the ship being thrown much over on her broadside. For three hours we remained unmolested, though the ice outside of the floe was moving in various directions, some pieces almost whirling round, and of course, in the effort, disturbing others. At 5 p.m., however, the piece near the ship having previously opened enough to allow of her resuming a nearly upright position, collapsed again with a force that made every plank complain; and further pressure being added at 6 o’clock, an ominous cracking was heard, that only ceased on her being lifted bodily up eighteen inches. The same unwelcome visitation was repeated an hour afterwards in consequence of the closing of a narrow lane directly astern. The night was very fine, but the vapour which arose from the many cracks as well as from the small open space alongside, quickly becoming converted into small spiculæ of snow, rendered the cold intolerably keen to those who faced the wind. Up to midnight we were not much annoyed, and for four hours afterwards, on February 21st, all was quiet. Every man had gone to rest with his clothes on, and was agreeably surprised on being so long undisturbed by the usual admonitory grinding. However, at 4 a.m. a commotion was heard, which appeared to be confined to the angle contained between west and north-west. On looking round at daybreak it was found that the ship had been released by the retreating of the ice, and had nearly righted; but at 5 a.m. she rose eighteen inches as before; she was then at intervals jerked up from the pressure underneath, with a groan each time from the woodwork.” And so it went on from day to day, Back and his men being kept incessantly at their duties, and constantly at work examining, and, where it was possible, strengthening the ship. Up to the middle of March they were, however, still safe, but on the 15th they were destined to witness trials of a more awful nature.
