“I suppose it must be traveled occasionally.” And Raymond stood up and looked along the cañon wall. “That looks like a little ravine coming in up there. Let’s see if there isn’t some place that we can crawl into for shelter.” “Yes, I guess we’d better.” And Sidney stood up and stretched stiffly. “We are certainly too exposed here. But do you know, Ray, I’m so lame and sore that I can hardly move.” “I’m not very lame,--just tired, that’s all; but then you worked harder than I did.” The boys moved slowly along the sand to the cleft in the cañon wall which Raymond had indicated. They found a very narrow chasm that had been cut through the rock by the occasional torrential rains of centuries. Its bottom, for some yards back, was on a level with the sandy floor of the cañon and was not more than ten feet wide. Overhead the cleft was very irregular, in places the two walls nearly coming together. Extending back on the right side beneath the overhanging rock was a sheltered space, very like a small cave. “Gee! Sid,” exclaimed Raymond, “that’s a fine place, and nobody can see us from the cañon. But, jiminy! where are our blankets? Did we leave them up on the mountain?” “I guess we did. I hadn’t thought of them at all. But I don’t believe I can crawl up there after them to-night; I feel too gone for anything.” “No wonder you feel gone,” said Raymond; “we haven’t eaten a thing to-day. We’ve been so busy drinking since we got down to the cañon that I had forgotten all about grub.” “I can’t remember exactly,” said Sidney, “but I don’t think there is much grub.” “Well, there’s some, anyway. You get out what there is, Sid, and I’ll take the cup and bring up some water. I feel as though I should want to keep right on drinking forever.” It had been very late in the morning when the boys roused from their night of stupor on the side of the mountain, and then it had taken a long time for Sidney to get himself and his brother down to the bottom of the cañon. After they had reached water they were also a long time in getting back any semblance of strength, so when they retreated to the little cave under the cañon wall, it was nearly night and the sun had already dropped back of the mountains. Sidney, when he examined the knapsacks, found there was a moderate supply of bread and cheese. The latter, with water to remove the effect of its salty condition, was extremely palatable, and the boys made what they declared was a sumptuous supper. “Do you realize, Sid,” said Raymond, as they lay on the sand munching bread and cheese, and frequently sipping water, of which they seemed never to be able to get enough, “that we have eaten nothing for twenty-four hours, and then only a little bread in that deserted house, because we had no water to wash it down? And we’ve done some strenuous work since, too.” “We haven’t eaten much, but you know we did eat a little bread up on the mountain last night.” “I don’t remember eating any bread,” declared Raymond.
