"We must have snow-shoes," said Ree, when he saw what was taking place, and the third day the boys ventured forth on such contrivances as they had made and did finely with them on the thick, slippery crust which had formed. Taking their rifles, they made their way through the river valley, which, farther up the stream, became quite narrow, steep, rocky banks rising on both sides to a height of fifty feet or more. No sooner had they entered this canyon than they found evidences of deer and other animals having taken shelter there. Going quietly forward, the lads discovered four of the timid, beautiful creatures huddled together. They went quite near before the deer leaped away through the frozen snow, and Ree quickly brought one down. John did better--or worse--killing one and wounding another. They secured the skins and choice parts of the meat and hanging these in a tree for safety, pushed on after the two which had escaped. They especially desired to capture the doe which had been wounded, not so much for its value, but because Ree insisted that it would be downright cruelty to let the poor creature suffer from its injury for days, perhaps, then die at last. But the young hunters traveled far before again coming upon the animals they sought. The trail took them out of the narrow valley or canyon, and a long distance through the woods to a locality they had never before visited, where the earth was cut by deep ravines, zig-zagging in nearly all directions, and great rocks often obstructing the way. Here the trail of the deer they were following was lost amid the tracks of others which had gone into the deep rugged gullies to escape the stinging wind. "We may as well give it up, Ree," said John, as they sat down to rest. "Oh no, we mustn't give up," Ree answered, "but I'll tell you what we'd better do. It is more than likely the Indians will be out in snow shoes the same as we are, and they may want to swap some dollar furs for penny knick-knacks this afternoon. One of us should be at the cabin." "I'll go," John willingly responded, for he liked to trade with the Indians, and could make much better bargains than Ree; not but what he was honest, but because Ree was so generous that he was often imposed upon. "Will you stop for the venison we left in the tree?" Ree asked. "I think I'd better; there is no knowing where you will be when you find that wounded deer! But don't stay out all night!" With this sally John started homeward, and Ree resumed his search for blood-stains in the snow which would show him the trail he sought. Going about among the rocks he discovered an opening about half the size of a door which seemed to lead straight back into a rocky cliff.
