He suddenly pulled himself together with a jerk. He could not sit there all day dreaming. He had come to find a winter home for Albert and himself, and he had not yet found it. But he had a plan from which he had been turned aside for a while by the sight of the lake, and now he went back to carry it out.

There were two clefts opening into the mountains from his side of the river, and he went into the first on the return path. It was choked with pine and cedars and quickly ended against a mountain wall, proving to be nothing but a very short canyon. There was much outcropping of rock here, but nothing that would help toward a shelter, and Dick went on to the second cleft.

This cleft, wider than the other, was the one down which the considerable brook flowed, and the few yards or so of fertile ground on either side of the stream produced a rank growth of trees. They were so thick that the boy could see only a little distance ahead, but he believed that this slip of a tributary valley ran far back in the mountains, perhaps a dozen miles.

He picked his way about a mile and then came suddenly upon a house. It stood in an alcove protected by rocks and trees, but safe from snow slide. It was only a log hut of one room, with the roof broken in and the door fallen from its hinges, but Dick knew well enough the handiwork of the white man. As he approached, some wild animal darted out of the open door and crashed away among the undergrowth, but Dick knew that white men had once lived there. It was equally evident that they had long been gone.

It was a cabin of stout build, its thick logs fitted nicely together, and the boards of the roof had been strong and well laid. Many years must have passed to have caused so much decay. Dick entered and was saluted by a strong, catlike odor. Doubtless a mountain lion had been sleeping there, and this was the tenant that he had heard crashing away among the undergrowth. On one side was a window closed by a sagging oaken shutter, which Dick threw open. The open door and window established a draught, and as the clean sweet air blew through the cabin the odor of the cat began to disappear.

Dick examined everything with the greatest interest and curiosity. There was a floor of puncheons fairly smooth, a stone fireplace, a chimney of mud and sticks, dusty wooden hooks, and rests nailed into the wall, a rude table overturned in a corner, and something that looked like a trap. It was the last that told the tale to Dick. When he examined it more critically, he had no doubt that it was a beaver trap.

Nor did he have any doubt but that this hut had been built by beaver trappers long ago, either by independent hunters, or by those belonging to one of the great fur companies. The beaver, he believed, had been found on this very brook, and when they were all taken the trappers had gone away, leaving the cabin forever, as they had left many another one. It might be at least forty years old.

Dick laughed aloud in his pleasure at this good luck. The cabin was dusty, dirty, disreputable, and odorous, but that draught would take away all the odors and his stout arm could soon repair the holes in the roof, put the door back on its hinges, and straighten the sagging window shutter. Here was their home, a house built by white men as a home, and now about to be used as such again. Dick did not feel like a tenant moving in, but like an owner. It would be a long, hard task to bring their supplies over the range but Albert and he had all the time in the world. It was one of the effects of their isolation to make Dick feel that there was no such thing as time.

He took another survey of the cabin. It was really a splendid place, a palace in its contrast with the surrounding wilderness, and he laughed with pure delight. When it was swept and cleaned, and a fire blazing on the flat stone that served for a hearth, while the cold winds roared without, it would be the snuggest home west of the Missouri. He was so pleased that he undertook at once some primary steps in the process of purification. He cut a number of small, straight boughs, tied them together with a piece of bark, the leaves at the head thus forming a kind of broom, and went to work.

He raised a great dust, which the draught blew into his eyes, ears, and nose, and he retreated from the place, willing to let the wind take it away. He would finish the task some other day. Then the clear waters of the brook tempted him. Just above the cabin was a deep pool which may have been the home of the beaver in an older time. Now it was undisturbed, and the waters were so pure that he could see the sand and rock on the bottom.
