It took but a few minutes to skin the deer and hang the carcass up in one of the cottonwood trees, where it would be safe from any wolf or coyote that might come about the camp, and then catching up their riding horses, they saddled them and started up the stream.

For several miles the bottom was wide and usually thickly fringed with willows. Several times they dismounted, tied their horses, and went in as far as they could toward the main stream, but twice they were stopped by water, or mud, or by beaver sloughs that were too wide for them to cross. Hugh said little, but shook his head from time to time as he looked over the valley. It was evident that he was dissatisfied. Jack forebore to ask questions, for he could see that Hugh was occupied in observing, and was thinking hard. They had gone five or six miles up the valley, and it was now about noon, when, on rounding a point of willows, they could see before them quite a large pond.

Hugh drew up his horse and for ten or fifteen minutes sat there watching, and then drawing back, he rode up behind the willows, dismounted, and tied his horse. Jack did the same.

"This looks better, son," said Hugh. "We'll go in here afoot as far as we can and watch this pond and see what we can see. I think there are beaver here, and probably this is the place we want to camp by."

As quietly as possible they made their way toward the edge of the water, passing on the way several trails where the beaver had been dragging brush to the water. The signs showed that this had been done no longer ago than last night, for on the ground were scattered fresh, green willow and cottonwood leaves, and in two or three places the bark had been knocked off willow stems by whatever had been dragged along, and these wounds were absolutely fresh. Presently they came to the edge of the willows, and still keeping themselves concealed, crept up to a little knoll, where they sat down and peered through the tangle of stems out over the pond. There before them was a long dam which Jack, with his experience of the day before fresh in his mind, could see had been recently worked on. Out in the water were a number of the hay-stack-shaped houses of the beaver, and even while they were looking, to Jack's astonishment and delight a beaver appeared on one of them, carrying in his mouth a long, white, peeled stick which he placed among others on the roof. Jack looked at Hugh, wondering if he had seen the beaver, too, and Hugh gave a little motion of his head. At two or three points on the dam animals were at work, beaver, of course, but too far off to be certainly recognized. Jack wished with all his heart that he had brought his glasses.

For nearly an hour they sat there, and then crept away as noiselessly as they had come, apparently unobserved by the animals.

When they had returned to their horses, Jack felt that he might speak. "Wasn't that a pretty sight, Hugh?" he said. "I don't think I ever saw anything quite as fine as that. I believe it would be a great deal more fun just to get up close to these beaver and watch the way they live, than it will be to trap them and kill them."

"So it would, son," said Hugh, "if we were just coming out for fun; and I reckon it's pretty nearly as good fun for me to watch them critters as it is for you. At the same time I feel as if we needed some of that fur that is swimming around there, and as if we were going to get it. It'll be quite a lot of work, but it's work that will be fairly well paid for."

"Yes, Hugh, of course you're right. I want to trap some beaver and get some fur, and either take it home or sell it; but didn't we have a good time when we were sitting out there watching those animals? I tell you, when that beaver crept up on the house there and put that white stick in it's place, my heart pretty nearly jumped out of my body. I never expected to see anything like that."
