In attempting to cross Baffin's Bay, by penetrating what is called the "middle ice," the _Fox_ was beset, and finally frozen in for the winter; and here, although their voyage may be said to have just commenced, they were destined to spend many months in helpless inactivity and comparative peril and privation. Their little vessel lay in the centre of a field of ice of immense extent; so large, indeed, that they could not venture to undertake a journey to ascertain its limits. Yet this field slowly and steadily descended Baffin's Bay during the whole winter, and passed over no fewer than 1385 statute miles in the space of 242 days, during which period the _Fox_ was firmly embedded in it! It is with difficulty the mind can form any adequate conception of the position of those voyagers;--unable to move from their icy bed, yet constantly drifting over miles and miles of ocean; uncertain as to the where or the when of their deliverance from the pack; exposed to the terrible dangers of disrupting ice, and surrounded by the depressing gloom of the long arctic night. At length deliverance came; but it came surrounded by terrors. In February, McClintock writes thus: "Daylight reveals to us evidences of vast ice-movements having taken place during the dark months, when we fancied all was still and quiet; and we now see how greatly we have been favoured, what innumerable chances of destruction we have unconsciously escaped. A few days ago, the ice suddenly cracked within ten yards of the ship, and gave her such a smart shock that every one rushed on deck with astonishing alacrity. One of these sudden disruptions occurred between me and the ship, when I was returning from the iceberg. The sun was just setting as I found myself cut off... At length I reached a place where the jagged edges of the floes met; so crossed, and got safely on board." Again, in March, he says, "Last night the ice closed, shutting up our lane; but its opposite sides continued for several hours to move vast each other, rubbing off all projections, crushing and forcing out of the water masses four feet thick. Although one hundred and twenty yards distant, this pressure shook the ship and cracked the intervening ice." Soon after that, a heavy gale burst upon them from the south-east, encircling them with snow-drift so dense that they could neither hear nor see what was going on twenty yards off. At night the ship became suddenly detached from her wintry bed, and heeled over to the storm, inducing them to believe that the whole pack had been broken in, and was pressing against them. This was not the case. A large mass of ice had protected them; but at a distance of about fifty yards, ice of four and a half feet thick had been crushed to atoms. Soon after, the protecting mass yielded, and the _Fox_ received a nip which lifted her stern about a foot, while occasional groaning from her sturdy little hull replied to the wild surgings of the ice without.
