"I don't know anybody, son," he said, "who would be taking horses through here, and I don't know where they'd be taking them to, without it's up to some small town north, or up to the new railroad, and then I don't see why they should be coming this way, unless perhaps they wanted to get over on Powder River and follow that down. The railroad, I hear, is pushing west from the Missouri, and it may be that some contractor came down here to get horses. And yet that don't seem right either. These are not work horses,—you can see that from their tracks,—and besides that there are lots of colts with them. If it was a few years back, I should think that a bunch of Indians had gone through; but then there are no travois trails, and I don't know what it is. Might be horse thieves; it's been so the last few years that people are stealing stock some."
The trail came from down the river, and they had followed it for some miles when a dark spot seen on the bottom showed a large animal lying down. Hugh rode over and found it to be a dead horse. He waved to the boys, who followed him, and they sat there on their horses, looking down at it. The animal had been dead perhaps a day; it lay on its side, and the brand was plainly visible. As Jack looked at the brand he recognized it as his uncle's, and he looked at Hugh in perplexity to see what this could mean. For a time Hugh said nothing, and then getting down from his horse, he looked more closely at the brand, and then, re-mounting, said to the boys, "We'll camp right here; over in that bunch of timber."
It was but little after midday, and Jack knew that something important must have happened, but he asked no questions, waiting for Hugh to speak. After they had unsaddled, and put up the lodge, Hugh told the boys to picket the three riding horses while he got dinner. Jack had told Joe about the brand, and both boys were a good deal excited, wondering what was coming next.
After they had eaten, Hugh filled his pipe and said: "Now boys, I don't know what all this means, but to me it looks as if a gang of horse thieves had been riding our range and had driven off a bunch of horses, and among them some of ours.
"I know that three-year-old filly lying over there perfectly well. She had her first colt this spring. It looks to me as if she had been run so hard that it killed her. Maybe she got a chance to fill herself up with water, somewhere back. But anyhow, there she is, and she came from the ranch, and what is more, she never was sold to anybody. She's been driven here, and driven so hard that it killed her. Now I am going to find out, if I can, what this means. I am going to see if I can find this bunch of horses, and see whose they are and who has got them. If they, or any part of them, belong to us, or came from our country, why we'll get them back if we can. Of course if we can't get them back, why they've got to go on. I don't think there are enough horses in Wyoming to pay for the life of either of you two boys; but if these horses have been stolen I reckon we can get them back, and I am mighty sure we'll try.
"Now, presently, as soon as the horses have eaten, I am going off on the trail of this bunch. I want you boys to stop right here until I come back, and if I should not come back in the course of three days, I want you to go to the ranch and tell them what you've seen. It will be no trouble to get back home. You'll know when you get to Casper or to Fetterman, and you can cross the river most anywhere there, and then it's pretty nearly a straight shoot south. You and me have ridden enough around the country, Jack, so that you know the principal hills, and I'm sure you'll know Rattlesnake Mountain when you see it. You know where the ranch lies from there. You've got plenty of grub, and it's only a little more than two days hard ride to get home.
"But I expect that you'll see me back here about day after to-morrow, in the morning, and then I'll have something to tell you:—either that I haven't found the stock, or else that I have: and what it is; and who it belongs to.
"Now, I want some grub—just some of that dried meat. I won't have a chance to kindle a fire while I'm gone, and I've got to ride pretty fast and can't carry much. One thing I must have though, and that is your glasses, son."
Jack rose and went into the lodge and brought out his glasses and gave them to Hugh, who opened them, looked at the clasp of the case, and then, shutting it and seeing that the spring was in good order, tied a buckskin string around it. As the sun fell toward the west he sent one of the boys to bring in a horse and said to him, "Let old Baldy stay out there, and fetch the dun; he's stronger, and fatter, and tougher than any of the rest.
"Now, boys," he said, after he had mounted, "this next two or three days will be business; you want to forget you're boys, and think that we may have to do something pretty hard and pretty active before long. Don't go off hunting; don't neglect your horses; stay 'round camp, and keep a good lookout during the daytime. If you see anybody coming, get your horses in close and tie them among the trees. Keep your riding horses on picket all the time, and at night keep them pretty close to the lodge." Then he rode off.
