Discovering Banks Land, which the Eskimo called "The Land of the White Bear," M'Clure followed Prince of Wales Strait to its northern entrance, where he anchored his ship to a floe and wintered in the open pack in default of a harbor. Retracing his course to the south the following summer, he circumnavigated Banks Land under marvellous ice conditions of great danger, escaping as by miracle, the _Investigator_ being so near the sheer, precipitous crags of the west coast that her yards could touch the cliffs, while to the seaward she was cradled in crashing, uprearing floes which close to her bows were higher than the foreyard. After reaching Banks Strait the ship grounded one night and M'Clure unfortunately decided to winter there, in Mercy Bay, where she was frozen in and abandoned two years later. This sketch sets forth the desperate extremities to which M'Clure and his crew were reduced, and describes the timely heroism of Lieutenant Bedford Pim R.N., in making the sledge journey which wrought such marvellous changes in the fate and fortunes of the ice-imprisoned men. * * * * * [Illustration: Route of Pim's sledge journey.] On September 23, 1851, the _Investigator_ was frozen in for the winter in the ice of Mercy Bay, on the north coast of Banks Land. It was her second arctic winter, and the hardships inseparable from prolonged polar service were soon felt. The crew were at once placed on two-thirds allowance, a restricted diet that kept them always hungry. Soon they felt the shadowy presence of the twin arctic evils, famine and cold, which came with the forming ice and the advancing winter. Through the open hatchways the down-flowing polar cold turned into hoar-frost the moisture of the relatively warm air of the cabins and of the bunks. Water froze in the glasses and frost particles welded into stiffness the blankets, bedding, and hammocks of the seamen. Later even the ink froze in the wells, while the exposed head of every metal bolt or nail was covered with a glistening coat of ice. Shoreward the outlook was as desolate as conditions were gloomy on shipboard. For at first the ice-bound shores of Mercy Bay seemed utterly barren of life in any form. But one day came with joy and thankfulness the report that a sharp-eyed boatswain had seen several deer skirting the snowy hill-tops to the southwestward. Now all was activity and bustle, since this phase of useful effort had come to increase their chance of life. Should they fail to release the ship the coming summer, death by famine sorely threatened. So they pursued the chase daily with the utmost energy and for a time with marked success. Not only did the hunters meet with the timid deer and the stolid musk-ox--their main reliance for meat--but here and there they found the snowy polar hare, the cunning arctic fox, and too often, alas! the ravenous wolf--the dreaded pirate of the north.
