"It won't be half as hard to bear as the hunger I'll feel in the course of an hour or two if we don't get one of them." The plan was so simple that no explanation was necessary. Jack Dudley had only to remain extended on the ground where he was, with his Winchester ready, and keep an eye on the little herd, which could not observe him unless he was unusually careless. He could easily judge of Fred's success or failure by watching the animals, and it would seem that success was almost certain for one of the young hunters. The only thing to be feared was that Fred would betray himself before reaching the other side of the game that was so tempting to both. The comrades looked at their watches at the moment of separating, and found it was precisely one o'clock. Fred gave himself an hour to reach a point from which to start on his return, though it was possible that double that time would be required. Before the interval had expired Jack had his glass to his eyes, and was studying the valley below. As the antelope cropped the rich grass they occasionally took a step in the direction of the watcher; but the largest one, evidently the leader, changed his course so as to work back toward the little grove of trees, the others following. Now and then the leader raised his head and looked around, as if suspecting danger, though his fears were not confirmed. At longer intervals other members of the herd did the same, but it was evident that they neither saw nor scented anything amiss. Jack's constant fear was that Fred would betray himself through some accident. His course would bring him nearer the game and the risk was considerable; but as the minutes passed without anything of that nature taking place, his hope increased. "More than likely Fred himself will get the shot instead of me. It makes no difference, so that we don't lose our supper; for," he added, dismally, "the dinner is already gone." When another half-hour had passed, he was sure his chum was on the other side of the herd. "There must be a break pretty soon. Suppose that instead of coming toward me," added Jack, giving expression to a dread that had not occurred to him until then, "they dash off into the mountains on either side. Then we shall be doomed to starvation!" He thought that with the aid of his glass he would be able to follow Fred as he stole down the side of the valley, since the position of the spectator was much more elevated than that of the antelope. It would require sharp scrutiny even with the aid of the instrument to do this, and, look as keenly as he might, he could discover nothing that suggested anything of that nature. When three o'clock went by without any evidence of alarm among the animals browsing in the middle of the valley, Jack Dudley began to wonder what it could mean.
