Young Powell said to Jack, "The dogs had some hard runs yesterday, and I don't want them to be chasing antelope to-day, and so far from home. I don't run antelope often, anyhow, though I've got some with these dogs, but I use them mainly for wolves and coyotes; and it's a bad thing to have a lot of dogs think that they can run anything that gets up before them on the prairie. If I was going to run antelope, I'd have a special bunch of dogs for running them, and for nothing else." "Then they've caught antelopes, have they?" asked Jack. "It hardly seems to me as if anything could catch an antelope, when it's really running as hard as it can." "Oh, I don't know," said Powell, "there's lots of difference in antelopes. Some of them can run twice as fast as others. I almost roped an old doe once in a fair chase, and I wasn't riding anything but a slow cow pony at that. I never felt quite sure though whether I could have caught her or not, or whether she was just fooling me. I ran her and she took down a valley, and I caught up with her, and got so close that I was just getting my rope ready to throw, when she ran across a little green place where the grass stood pretty high. I would not have tried to cross it if I hadn't been after her, for it looked kind of wet, but I couldn't stop, and I put the spurs into the old horse, and he jumped right into the middle of it and stayed there, and I kept going and hit the hard ground on the other side. When I got up and caught the horse, the antelope was out of sight. Still, I know mighty well that there's a big difference in antelope. You take an old buck, and even if you get a good start on him, the dogs have a hard time to get up to him. You take an old doe, or a yearling buck, and it's almost always caught a heap easier. You see those two little blue dogs, the smooth ones, the two that are ahead? They're the fastest dogs I've got. I always depend on them to stop a coyote or a wolf. If they can catch him and throw him it's a mighty short time till the other dogs get up, and then they all pitch in and chew him. These two yellow, rough-haired dogs here, the biggest ones, they're the fighters. They bring up the tail of the chase, but when they get to the wolf they don't stop, they pitch right in. If it's a coyote, one of them generally gets him across the chest and the other in the flank, and then the rest of the dogs take hold wherever they can, and they all pull in different directions. It don't take no time at all to kill a coyote, but of course a big wolf is different. I've had three dogs killed by wolves, and each one only had one bite. They're terrible strong, powerful animals.
