It was into one of these most striking nooks that the three had now come. They had been in a valley of the same type before, but this was far deeper and far bolder. There were several acres of good grass, on which the horses and mules might find forage, even under the snow, and the lake, two or three acres in extent, was sure to contain fish good for eating. But the two men examined with the most care the rocky, western cliff, weathered and honeycombed by the storms of a thousand centuries. As they had expected, they found great cave-like openings at its base, and after much hunting they decided upon one running back about fifty feet, with a width half as great, and a roof varying from seven to twenty feet in height. The floor, fairly level, sloped rather sharply toward the doorway, which would protect them against floods from melting snows. The interior could be fitted up in a considerable degree of comfort with the material from their packs and furs they might take. They found about fifty yards away another, though shallower, cavern which Will, with his gift for dealing with animals, could induce the horses and mules to use in bad weather. He proved his competency for the task a few hours after their arrival by leading them into it, tolling them on with wisps of fresh grass. "That settles it so far as they are concerned," said Boyd, "and we had to think of them first. If we're snowed in here it's of the last importance to us to save our animals." "An' we're goin' to be snowed in, I think," said the Little Giant, looking at the sombre heavens. "How high up did you say we wuz here, young William, ten miles above the level o' the sea?" "Not ten miles, but we're certainly high, high enough for it to be winter here any time it feels like it. Now I'm going to rake and scrape as many old dead leaves as I can find into the new stone stable. The floor is pretty rough in places, and we don't want any of our beasts to break a leg there." "All right, you set to work on it," said Boyd, "and Giant and me will labor on our own house." Will toiled all the day on the new stable, and he enjoyed the homely work. Sometimes he filled in the deeper places in the floor with chunks of dead wood and then heaped the leaves on top. When it was finished it was all in such condition that the animals could occupy it without danger, and he also set up a thick hedge of boughs about the entrance, allowing only four or five feet for the doorway. Even if the snow should be driving hard in that direction the animals would yet be protected. Then he led them inside and barred them there for the night.
