The old man thought a minute, glanced searchingly into the boy's eyes, who had come nearer to him in his earnestness, and then he said--"Come, then, and remember thy promise." They stepped out together, shut the trap-door behind them, and clambered up to the top of the rock, from which the broad footpath led up to the heights and abysses of the mountain. The moon poured its mystic radiance down from the deep blue sky of night, and the young foliage of the beech wood gleamed like silver as it fluttered in the breeze. Not a footstep was heard on the mossy ground, only their shadows glided in company with the lonely wanderers, who in silent haste pressed on deeper into the recesses of the mountains. The wood lay behind them, and the path led to a ravine, at the bottom of which a raging torrent rushed; they stood now at its edge. None save Tyrol's boldest mountain climbers know this path, and even they, though provided with ice-shoes and alpenstocks, tread its steep ascent with trembling hearts. But the little man seemed to heed no danger; fearlessly he set his foot upon the highest point, and securely, as if on level ground, he went down the side of the precipice, where one false step would have been certain death. The boy followed him with beating heart. The moonlight broke through the overhanging bushes and the lofty rocks overhead, and made its way down into the ravine. The wanderers stood now at the edge of the raging torrent, and walked along it to the high rock over which the glacier stream fell into its rocky bed, and which seemed to them, as it stood veiled in night, like one of the giants of old who, the old legends tell us, were turned to stone. Even in the distance they had seen the moving cloud of vapour above its head, which hovered in the light of the full moon, like a giant eagle, above the rushing waters. The milk-white billows of the torrent that rushed down from this height rolled in the moonlight like silvery tresses down from the rock's giant head. The old man walked quietly through the noise and foam round the foot of the rock and into a narrow cleft, which was the opening into the heart of the mountain; here he laid down his wallet.
