Jack could see this, and then as he looked over the pond he saw a long wake in the water close to the bank, and caught Hugh's arm and said, "Look there. Hugh, away over there under the bank. What is that swimming? Of course, it may be a duck, but may it not be a beaver?"
Hugh looked carefully, and presently the object which was swimming passed a little bay so that it was distinctly seen as a small, round object. "That's a beaver, son," said Hugh. "You can see for yourself that it isn't a duck, and the only other thing it could be would be an otter or muskrat. It is too big for a muskrat and it doesn't seem like an otter. There are beaver down there, and what's more, they haven't been disturbed for a long time, or else they wouldn't be out swimming around like that in the heat of the day. Let's go down and take a look around; but keep quiet; don't make any quick motions, and whatever you see, don't fire your gun. If there are any beaver there we want to get some of them."
The two walked slowly down toward the dam, taking advantage of whatever little cover there was in the way of inequalities of the ground or of willow brush. Down close to the water's edge grew a good many willows, and they were thus able to get quite close to the dam, and sitting down there they watched the water. For a long time, as it seemed to Jack, it was absolutely still, and then, while he was staring as hard as he could at the farther bank and the place where the dam met it, Hugh touched him and made a little motion with his head, and Jack, following the direction of his companion's eyes, saw, not more than twenty-five yards off, two beaver swimming down toward the dam, each with his head slightly turned to one side, and each dragging after him a green stick about three or four feet long. The two animals came on down to the dam, and without the slightest suspicion that they were being watched, crawled out of the water, dragging their sticks after them. When they left the water they were so close to the watchers that they were hidden from them by the dam, and just what they were doing could not be seen. Jack touched Hugh, and when he bent down his head, whispered to him, "Couldn't we crawl up a little closer and watch them?" Hugh shook his head. A few moments later the two beaver entered the water again and swam off up the pond. When they had disappeared Hugh touched Jack, and turning about, they crept away among the willows in the direction from which they had just come.
When they had left the dam some way behind them, Hugh stopped and said to Jack, "Now, let us go on up this pond, and try to see where these beaver are living and where they're working. Keep out of sight as much as you can. I don't want them to know that there are any people about. It looks to me as if nobody had been trapping here for years, and as if we had struck something good. Now, come on, I want to walk fast and find out all I can to-night, and then we've got to get back to the camp as quickly as we can." They hurried along up the stream, Hugh looking carefully at the willows and aspens along the border of the meadow, and sometimes going down toward the edge of the pond. They crossed a number of places where branches, some of them quite large, had been dragged over the ground, but Hugh contented himself with saying to Jack, "You see, these beaver are working all along here, and they have to go quite a little way for their food."
The beaver pond was quite a long one, but at last they reached its head. Here they came upon a game trail which seemed to lead back across the stream, and turned into it in the hope that it might lead them to the other side. From one high point above the pond they got a good view of its whole length, and Hugh pointed out half a dozen grayish brown objects raised two or three feet above the water's surface, which he told Jack were beaver houses. "It may be, son," he said, "that we'll have to bring our outfit across and camp up at the head of this pond. It's too far from our present camp for us to trap here conveniently."
The game trail led them across the wide stream valley by a good, hard road. At only one point was it deep and muddy, and just here by good luck they found an old cottonwood tree, felled long ago by the beavers, which bridged the bad place.
Once on the other side of the valley, they turned sharply down stream, and after a long walk, reached the game trail by which they had crossed it earlier in the day. They went down this until they came to the place where the lynxes had been hung up, and getting these, they went back to camp, reaching it just about sundown.
"Well," said Hugh, "I feel as if we'd had quite a walk. I guess you are ready for supper, aren't you, son?"
"You bet I am," said Jack; "but the first thing I want to do is to shed these rubber boots. They seem to me the heaviest things I ever had on my feet, and I believe I've got three or four blisters from walking in them. I'd rather go barefoot than wear these again."
"Don't you believe it, son," said Hugh. "You'll be mighty glad of them boots before many days, now. I expect before long to have you wallowing around in the mud and water like a terrapin."
