But at last his courage came back and he began his painful progress upward once more. Foot by foot he climbed, and at last, when resting on a ledge, he dared to look about him to see what progress he had made. To his delight he saw that he had come more than halfway up the precipice, although above him its rugged face still towered frowningly as if daring him to surmount it. [Illustration: THE SIGHT OF THE DIZZY HEIGHT ALMOST UNNERVED HIM.] “Well, I would never have believed that I could have climbed to such a height with so little inconvenience,” mused the boy. “Of course, the climb is a good deal rougher than it looks from below; but still it’s an experience I wouldn’t go through again for hundreds of dollars.” Having rested on the ledge and munched some deer meat and acorn flap–jack which he had brought with him, Jack recommenced his climb. It spoke marvels for his cool head, great strength and wonderful endurance that the boy had progressed as far as he had. Few but an American youth of the most steel–like fiber and sterling grit would have dared to undertake such a task. And yet, before Jack there still lay the hardest part of his endeavor. So steep was the cliff face now that the lad did not dare to pause in his climb. He steadily progressed although his hands were cut and bleeding by this time, and his feet ached as cruelly as did other parts of his anatomy. But just when it seemed to the lad that his body could not stand another fraction of an ounce of strain, he happened on a place where a watercourse from above had cut a sort of shallow cleft in the precipice. In this grew shrubs and several trees, and Jack struggled to gain this oasis in the dangerous desert of his climb for life. Gaining it, he flung himself at full length on a bed of sweet smelling yellow flowers under the shade of a broad–leaved bay tree. In the stillness of that lonely and awful height, halfway between earth and sky, his breathing sounded as loud as the exhaust of a steam engine. But by–and–by he recovered his breath, and began to wish with all his soul for some water. That fearful climb had racked both nerve and muscle; but even more than his fatigue did Jack feel the cruel pangs of a burning thirst. Some grass grew in that lonely little grove on the cliff face, and he chewed some of this for the sake of the moisture that exuded from it. But this was far from satisfying. In fact, it only aggravated his thirst by mocking it. He rose on one elbow and looked about him. At a short distance up the steep, dry watercourse he saw a patch of vivid green. To his mind that could betoken nothing but the presence of water near the surface. At any rate he felt that it was worth investigating. Reaching the patch of verdure, the boy fell on his hands and knees, and with a sharp–edged stone began scraping away at the ground. To his unspeakable delight he had not dug down more than a few inches before the ground began to grow moist.
