The situation was gloomy enough so far as Roger was concerned, for he was practically without food, but what rendered the matter doubly serious was that the rest of the party would come in from the side camp two days hence with their supply of provision exhausted, only to find the camp barren, and leaving five men a long way from getting food instead of one. The more Roger thought over the matter, the more determined he was that he must procure supplies. The question was, where? If the lad had known the country at all, there were undoubtedly ranches somewhat near at hand to which he could appeal at a pinch, but he had wisdom enough to know that it would be the height of folly to ride out upon the north Arizona plateau without the faintest idea of a destination. There was the ranch to which he had been told to come, and he had heard of it often enough to know that it was one of the largest ranches in the country, but who would direct him there? He feared that a blind try in the plain might put him out of touch of water as well as food, a condition insupportable. There was only one bright spot in the position, and that was the presence of Jack. Jack was a burro, apparently of extreme age, who had been found one morning near the camp, and who had attached himself to the party. Of course all the rest of the animals were away, the cook having ridden back to the side camp the horse on which Roger had come from there. True, there was this burro, but what could he do with it, where could he go? As he asked himself this question, an answer shot into the boy's mind which turned him hot and cold. He looked over the plateau to the plains and shook his head, then quietly went into the tent to think over the best course for him to pursue. Five, ten, fifteen minutes passed, then with jaw hard-set and lips compressed Roger walked to where the burro was grazing, and slipped a halter over his head. Obediently the patient animal followed him to the edge of the rift of the Canyon, and there Roger looked down and across. Nine miles away, across those fearful chasms and lurid cliffs lay food and necessaries not only for himself, but for the party. Roger was conscious that prudent judgment would counsel his return to the side camp for the purpose of informing the party of the situation, so that they could cross by the old trail to renew supplies, but the boy knew that Masseth was working against time. Beside this, it would be a great achievement and the lad was burning with a desire to shine before the Survey. The old trail was the better way, but it had been night when they debouched on the plateau and Roger could not have told where the trail entered. He feared he might lose time by hunting for that faint trail, and decided to direct his whole strength into an attempt to force his way straight across the cleft in defiance of the decree that it had never been done and could never be done.
