the top, he thought, he would build a little tower of stones, the way explorers always do.But at the end of two hours' steady climbing, he was ready to admit that he would never reach the peak that day. It still rose above his head, seeming as far distant as ever. But he did not care now. It had been a glorious climb, and the distance he had already covered was a considerable one. He looked back. The town looked like a model of a town, with little toy houses and different-colored roofs among the trees that made a darker patch on the pattern of the valley floor. The mountains on the other side of the valley seemed like blue clouds stretching out over the edge of the world. Even the peak could not give him a better view than this. David gazed up the face of a scarp which rose like a cliff above him--a smooth, bare wall of rock that had halted his climb. Halfway up the scarp was a dark horizontal line of bushes, something like a hedge. Apparently there was a ledge or shelf there, and he decided to climb up to it before he returned home. To scale the rock face itself was impossible, however: there were no hand or foot holds. So he turned and made his way through the grass until he reached the end of the bare stone. Then he started upward again. It was hard work. Vines clutched at his feet, and the close-set bushes seemed unwilling to let him pass. He had one nasty slip, which might have been his last if he had not grabbed a tough clump of weeds at the crucial instant. But, oh! it was worth it. He felt like shouting when at last he reached the ledge. Truly it was an enchanted place! It was a long, level strip of ground, several yards wide, carpeted with short grass and dandelions. Bushes grew along most of the outer edge. The inner edge was bounded by a second scarp--a wall of red stone with sparkling points of light imbedded in its smooth surface. David threw himself on the grass and rolled in it. It was warm and soft and sweet-smelling; it soothed away the hurt of his aching muscles and the sting of his scratches. He rolled over on his back and cushioned his head in his hands. The sky seemed to be slipping along overhead like a broad blue river. The breeze ruffled his hair and whispered, the bushes murmured and gossiped to each other. Even the sunlight seemed to hum to him as it laid warm hands on his face. But there was another sound, which now and then rose above these murmurs. Then it would fade and be drowned out by the breeze. Hard to say why, but it just did not seem to fit there. David propped himself up on his elbows and listened more intently. The sound
