A wide passage went to the right, and in front of him Alan saw a large chamber, bounded on one side by the lake. Branching off in all directions were other passages which seemed to open out into other chambers and roadways, in fact the whole place seemed like a veritable warren. Suddenly an awful crash sounded, followed by the beating of drums and the clashing of cymbals and away in the distance he saw a procession of purple folk passing rapidly, all in the same direction. Cloaks of the same purple hue fell from their shoulders, and the women wore veils on their heads. He watched them with interest. The figures passed in quick succession, then they became less and less frequent, until only one or two stragglers came hurrying up. The sound of singing rose on the air, and Alan conjectured that it must be some religious service to which they all were bent. After the last one had disappeared Alan waited some minutes to see if any more would pass, but as no one else came he walked slowly in the direction from which the multitude had appeared. In a very short space of time he found himself in a street. Peculiar huts lined either side of it, huts with their doors open wide and no sign of life. He looked about him carefully, and ventured inside one. He found it was divided into three rooms—all on the ground floor. There was a sleeping room, for mattresses of that same purple moss, dried, were on the floor; there was also a living room and a kitchen. Warily he looked about him, and then went out into the street. The main street merged into smaller ones and at last, at the very end, a large building rose upon the scene—larger and more impressive than any of the others he had passed on his way. All this time he had seen no sign of life—the inhabitants were content to rest secure in their belief of inviolability. Cautiously Alan crept toward the building and as he came close to it, he saw that a sentry had been left on guard—a sentry with an evil-looking knife slung across his shoulders, and a scimitar-like instrument in his hand. The man was looking away into the distance and did not hear Alan’s approach. “Hullo,” said Alan pleasantly. The effect was magical. The undersized creature swung round and faced the strange, white man. For an instant he remained quite still, and then, with a sudden movement that Alan was unprepared for, sprang at him, and commenced to beat his horn in Alan’s face. In vain the white man tried to free himself from the savage grip; he was no match for this strange creature of the underworld. His adversary made no sound as he gradually weakened Alan, and at length he swung him over his shoulder as if he had been a child, and marched with him at a quick pace down the street.
