This hole looked rather mysterious to Jack, and he wondered what there could be in it. He walked up to it and looked as hard as he could into the blackness, but he could see nothing. He wanted very much to go in, yet it was useless to do so unless he could see something when he got there. "If I only had a lantern now," thought Jack, "or even a candle, I could go in and see what is there. I'll bet no one at the ranch knows of this cave, and I'd like to find out all about it and tell them. That would be a good story to take back." He thought for awhile, and decided that he must make a torch; but what could he make it of? For a little while he could think of nothing to use. He remembered that in the books that he had read, people had always had birch bark for torches, or fat with which to make candles, but he had neither. Then he thought of pine torches of which he had read. There were plenty of pines growing here on the mountain, but nothing that he could make a torch of. Suddenly he remembered that dried pine needles burn brightly, though only for a little while, and that on the ground not far from here he had seen a half dozen pine limbs, twisted off from one of the trees in some heavy wind storm. He thought if he could tie a good many bunches of these needles together, they would make a torch for him. He crept out of the underbrush and saw near by several of these pine limbs, with the dried red needles on them, and he picked a number of the bunches. Now he needed some string. "If I only had Pawnee here," he thought, "I could take the strings from my saddle;" but Pawnee was feeding far below him in the valley. As he cast his eye about him, in perplexity, he saw a yucca plant growing on the slope, and he remembered what Hugh had told him about using the fibre of this plant for thread. He climbed up to it, cut off a number of the long bayonet-shaped leaves, selected a straight dead stick, and went back to his pile of pine needles. Splitting the tough leaves of the yucca, he found that they could be used as strings, and with these strings he bound his bunches of pine needles, one beneath the other, to the stick, and soon had what he thought might perhaps serve him as a torch. Going back to the mouth of the cave, he again looked into it, and listened, but all was darkness and silence. He parted the low growing bushes at the entrance, and stepped in, and then, lighting a match, touched it to the top of his torch. The bunch of pine needles flared up for two or three seconds, and then went out, but the light was enough to show that for six or eight feet further in there was a smooth floor to the cave, paved with small stones. The walls above and on either side seemed high. A second match, touched to another bunch of pine needles, gave another flame, lasting only an instant. Plainly, the torch would not burn from the top downward. The only thing to do was to light it below, and let the flames run up the stick. Jack lighted
