As autumn drew on they made ready to cross back to the mainland; but it took some time for the ice to form on the strait. Gilder said of their camp life: "We eat quantities of reindeer tallow with our meat, probably about half of our daily food. Breakfast is eaten raw and frozen, but we generally have a warm meal in the evening. Fuel is hard to obtain and now consists of a vine-like moss called _ik-shoot-ik_. Reindeer tallow is used for a light. A small, flat stone serves for a candlestick, on which a lump of tallow is placed close to a piece of fibrous moss called _mun-ne_, which is used for a wick. The melting tallow runs down upon the stone and is immediately absorbed by the moss. This makes a cheerful and pleasant light, but is most exasperating to a hungry man as it smells exactly like frying meat. Eating such quantities of tallow is a great benefit in this climate, and we can easily see the effects of it in the comfort with which we meet the cold." As soon as the ice on the strait was frozen hard enough the reindeer crossed it, and by the middle of October King William Land was practically deserted. Then the Americans and Eskimos started back to the mainland. Winter had now come, and the weather was intensely cold, often ninety degrees below freezing. In December the traveling grew worse, and food became so scarce that they had to stop day after day for hunting. In January a blizzard struck their camp and lasted thirteen days; then wolves prowled about them at night, and once actually killed four of their dogs. "A sealskin full of blubber," said Gilder, "would have saved many of our dogs; but we had none to spare for them, as we were reduced to the point when we had to save it exclusively for lighting the igloos at night. We could not use it to warm our igloos or to cook with. Our meat had to be eaten cold--that is, frozen so solid that it had to be sawed and then broken into convenient-sized lumps, which when first put into the mouth were like stones. Sometimes, however, the snow was beaten off the moss on the hillsides and enough was gathered to cook a meal." When they were almost on the point of starvation a walrus was killed, and supplied them with food to last until they got back to the nearest Eskimo village. From the coast they took ship to the United States. The records they brought with them practically completed the account of what had happened to Sir John Franklin's ill-fated expedition. And almost equally important were the new details they brought in regard to Eskimo life, and the proof they gave that men of the temperate zone could pass a year in the frozen land of the far north if they would live as the natives did, and adapt themselves to the rigors of that climate.
