"What animals are there, Hugh, that kill the beaver? I suppose man is the worst enemy it's got, but there must be a lot of others, such as wolves and, perhaps, bears."

"Yes," said Hugh, "a beaver has lots of enemies. As I have said to you, it's heavy and slow; it can't run away nor climb a tree, and it has no special means of defending itself. A beaver's got a good set of teeth, but while he can give one or two pretty strong bites, that would not help him much in a scrap with any animal near his own size.

"A bear, of course, would kill a beaver every time if he could get hold of him; so would a big wolf. A single coyote might not be able to, but two or three coyotes could get away with him in short order.

"Didn't you ever, back East, see a dog get between a woodchuck and his hole? You know the woodchuck will sit up and chatter his teeth, and perhaps he will bite the dog once when the dog runs in, but that's the end of the woodchuck. The beaver has got longer teeth, and can bite a little harder and deeper, but he is not built for fighting, and what's more, he never means to fight if he can help it.

"The wolverine sometimes lies around beaver ponds and maybe once in a while catches one, but wolverines are pretty scarce, and I don't think they get many. I believe that the animal that gets more beaver than any other is the lynx. They are small, to be sure, but they are mighty quick, and they have got those long claws, and they can jump on a beaver and cut him up pretty badly before he can get hold of them. I have often seen places where beaver had been killed, and I know it was done by lynxes; that is, by bob-cats, and also by the big gray lynxes. One time, a good many years ago, I saw a lynx waiting to catch a beaver. As it happened, he didn't get him, but he tried hard enough.

"I happened to be riding down William's Fork, and had to pass through a point of timber, and just before I got out to the pond, on the other side, I stopped my horse for a minute to look around and see what I could see. There was a big beaver dam just below me, on the river, and I knew of it, for I had often passed there. I could see nothing, and was just going to start on again, when, as I happened to look over across the creek just opposite me, I saw something move. For a minute I could not tell what it was, and then I saw lying among the sage brush a big bob-cat, whose color matched the ground and the weeds about him so well that it was hard for me to make out his shape. At one end of him, however, there was something black that kept moving regularly in little jerks, and, of course, I knew that this was his tail, and that he was watching something in the stream and getting ready to jump on it. I looked at the stream carefully, and for a moment could not see anything, and then, just below the bob-cat, I made out something swimming in the water, close under the bank, but to save my life I could not tell whether it was a duck, or a muskrat, or what. When this thing, whatever it was, had got nearly to the bob-cat, which kept crouching flatter and flatter all the time, the thing suddenly dived and hit the water a tremendous rap with its tail, and then, of course, I knew that it was a beaver that had been swimming up stream, and that the bob-cat had seen it, and was waiting for it to get within reach, and then was going to jump on it. Of course, bob-cats don't like the water very well, but all the same, they will go into it for food."

"What did the bob-cat do when the beaver dived, Hugh?" asked Jack.

"Oh, after a minute or two," said Hugh, "he seemed to realize that the game was up, and he then got up and walked away into the sage brush. I have often wished that the beaver had come on a little further so that I could have seen the end of the thing, and seen whether beaver or bob-cat would have come out ahead. You see, the beaver must have been swimming in pretty deep water, and, of course, if he had had sense enough to grab the bob-cat and hold on to him, no doubt he could have drowned him, but I don't reckon the beaver would have had sense enough for that; he would have just tried to get away, and I guess he would have succeeded."

"Well, Hugh," said Jack, "it is interesting to hear of these animals, but as you say, it's pretty hard work to really learn anything about them by reading or hearing people talk. The real way is to see the animals themselves, and I hope we will do that before very long."

"Yes, son, we ought to. In fact, by to-morrow afternoon we ought to get to where there used to be a great big beaver meadow. I don't know, of course, whether we will find any beaver there now or not, but it's a good place to go and look for them. I have seen the time when it was full of beaver, and if we could find it as full now as it was then, we ought to be able to load up a pack horse with fur."
