"Why, what a big knife," said Jack. "It's almost like a sword; but it isn't very sharp." "Not very," said Hugh, "but notice how it's whetted, round on one side and flat on the other. That's the way Indians always whet their knives. Queer, isn't it? Let's look around for something more. Let your horse go, after you've thrown down the reins; he won't move." The two separated and began to look over the ground, and in a moment Jack called out in a solemn way. "Oh, Hugh, look here; see what I have found!" and as the old man came up to him, he pointed out a human skull that lay half buried in the dirt in a little washout. "That's one of 'em," said Hugh, as he picked it up. It was very old, grey with weather, and all the teeth had fallen out. Higher up the hill were splinters of bones and even some whole bones of legs and arms, and sticking out of the ground among them was a long piece of iron, which when dragged from its resting-place, proved to be a rifle barrel. "Well, now," remarked Hugh, "if we keep this up we'll have a horse-load of truck to pack home with us." They looked further, gathering up one thing after another, and at length when they were ready to go home they had five Indian skulls, the rifle barrel, the knife, an old-fashioned T. Gray axe, such as was used in trade with the Indians in early days, some pieces of the wood of saddles, a couple of elk-horn fleshers and a stone scraper. All these things were very old; the iron deeply rusted, the bones and wood grey and split with age and weather. Hugh bundled these things into his coat and tied it on behind his saddle, and they set out for the ranch. Just as they got to the corral, the dinner horn sounded, and after unsaddling and putting their treasures upon the roof, which Hugh easily reached from the ground, they went to the house. Jack thought that he had never tasted a dinner quite as good as that one, and when he had finished he felt quite uncomfortable. A little while after dinner, Hugh said to Jack: "Now, son, go in and bring out your rifle, and let's see how it's sighted and how it pulls off. A man always must learn how his gun shoots before he can expect to kill anything. I've seen young fellows from the States come out to hunt, and start in and shoot away a heap of ammunition without hitting anything, and come to find out, they had never sighted their guns, and didn't know anything about where they shot. 'Course they couldn't hit anything. You get a box of ca'tridges and your gun, and we'll try to find out just what it can do, and afterwards what you can do."
