On hands and knees they crept forward a few feet, and then Hugh stretched out his hand and touched Jack, and motioned with his head. The boy stared at the grass before them which was shivering in the wind, but he could see nothing beyond it but the blue sky. At length Hugh bent toward him and whispered, "Don't you see his horns?" Instantly Jack saw that what he had seen several times and had supposed were two black looking weed stalks were the slender horns of an antelope. Hugh saw the change in his companion's face, and whispered again, "Crawl up a few feet more and then get up slowly, rest your left elbow on your knee, and aim just behind the shoulder and low down." Jack crept up past Hugh, and, rising very slowly on one knee, took a careful aim. The buck was lying on a point of the hill, with his face toward the valley and his back toward Jack, who aimed at the side just behind the shoulder and low down, and fired. The buck sprang to his feet, and in half a dozen low, rabbitlike jumps, disappeared over the hill. Jack had not had time to wonder whether he had missed or not, when he heard Hugh's voice at his ear saying, "Son, you done that well; no one could have done it better. Now, let's go and get the horses." "Well, but Hugh, where is the antelope? Did I hit him or did I miss?" asked Jack. "Why, you hit him, of course. Look where he ran. Don't you see that if you'd missed him he would have been in sight before now, either crossing that flat or running up on one of the hills. He ain't gone far. He's our meat." "Oh, I hope so," gasped Jack, who suddenly began to tremble as if he were cold. [Illustration: "JACK CREPT UP PAST HUGH ... AND TOOK A CAREFUL AIM."--_Page 84_.] When they had mounted, Hugh led the way to the place where the antelope had been lying. Here he pointed out the hoof tracks and followed them down the hill. Before long he stopped, and pointing at the ground, said, "See there." Jack looked, and saw a dark splash on the ground, and clinging to a tuft of the brown prairie grass, several bright red drops. After a moment's hesitation, he exclaimed, "Oh, that's blood, isn't it? Then I must have hit him." "Yes, indeed, he is hit. Now, you see if you can follow that blood trail. Don't keep looking at the ground just in front of you, look ahead of you and don't try to go too fast." Jack looked on the ground ahead of him, and saw other splashes, and starting on, soon saw that he could follow the marks much more easily and quickly in that way than he could by watching those which were close under his horse's head. They went on for a hundred yards further, and then, as they rounded the point of a little knoll, Hugh said, "There's your meat," and looking, Jack saw something white showing above the grass, and a moment later he was looking down on his first antelope.
