It was not very difficult to cross the field. The ground proved to be hard enough to keep their feet from being mired in the mud, and no unsurmountable obstacles confronted the two boys. Now and then Jack would pause to take an observation. At such times he first of all noted the position of the red lights, still in plain evidence aloft. After that he would make it his business to closely observe how the wind stood, and in this way get his bearings afresh. Amos watched his actions with great interest. He had picked up a certain amount of woodcraft knowledge in his association with the scouts, but Jack, on the other hand, had acquired his through practical experience. A year or two spent on a Western cattle ranch is bound to be an education in itself, and lucky indeed is the boy who can profit by it. Presently it became evident to Amos that Jack was proceeding more carefully. This convinced him that Jack must believe they were now drawing close to where the end of the cord that held the signal kite would be found. Then Amos also noticed there was some sort of low elevation beyond. It could hardly be called a hill, not being high enough for that, and yet at the same time it was more than a mere knoll. Out in African Zululand it would possibly have been called a _kopje_. Of course, having himself flown kites many a time, Amos readily recognized the value of such an uplift, free from trees as it was, and all other objects which were likely to become entangled with the kite string. Yes, he saw that Jack was bending lower now, and that he headed in a bee line for that raised ground. Amos became immediately interested. Would they make the discovery they anticipated, once they drew closer? There was no place in the immediate vicinity that offered such advantages in the way of elevation and freedom from interference. And accordingly it was with considerable faith that Amos continued to follow close at the heels of his cousin. The suspense that ensued was of brief duration. Then Amos began to follow the dim outlines marking the rounded summit of the squatty elevation as seen against the clouded heavens. Suddenly his eyes stopped traveling along that curve and remained riveted upon one particular point. Some object loomed up there, and broke the even contour of the “hogback.” “I do believe that must be a man!” Amos was saying to himself under his breath, while he kept his eager eyes riveted on the spot; and after he had followed Jack a little further he was convinced beyond any possibility of doubt that his guess had been a correct one, for he plainly saw the object move.
