Having decided to go, they became very impatient, but they did not skimp the work on the snowshoes, knowing how much depended on their strength, but that task too, like all the others, came to an end in time. Robert practiced a while and they selected a day of departure. They were to take with them all the powder and bullets, a large supply of food and their heavy bearskin overcoats. They had also made for themselves over-moccasins of fur and extra deerskin leggings. They would be bundled up greatly, but it was absolutely necessary in order to face the great cold, that hovered continuously around thirty to forty degrees below zero. The ear muffs, the caps and the gloves, too, were necessities, but they had the comfort of believing that if the fierce winter presented great difficulties to them, it would also keep their savage enemies in their lodges. "The line that shut us in in the autumn has thinned out and gone!" exclaimed Robert in sanguine tones, "and we'll have a clear path from here to the lake!" Then they rolled stones, as they had planned, before the door to their home, closing it wholly except a few square inches at the top, and ascended on their snowshoes to the crest of the ridge. "Our cave will not be disturbed, at least not this winter," said Tayoga confidently. "The bears that sleep below are, as I told you, the silent sentinels, and they will guard it for us until we come again." "At least, they brought us good luck," said Robert. Then, with long, gliding strokes they passed over the ridge, and their happy valley was lost to sight. They did not speak again for hours, Tayoga leading the way, and each bending somewhat to his task, which was by no means a light one, owing to the weight they carried, and the extremely mountainous nature of the country. The wilderness was still and intensely cold. The deep snow was covered by a crust of ice, and, despite vigorous exertion and warm clothing, they were none too warm. By noon Robert's ankle, not thoroughly hardened to the snowshoes, began to chafe, and they stopped to rest in a dense grove, where the searching north wind was turned aside from them. They were traveling by the sun for the south end of Lake George, but as they were in the vast plexus of mountains, where their speed could not be great, even under the best of conditions, they calculated that they would be many days and nights on the way.
