down toward the great pool and the awaiting scavengers of the deep.
At his four hundred and thirteenth step another corpse bumped against him—how many had passed him without touching he could not guess; but suddenly he experienced the sensation of being surrounded by dead faces floating along with him, all set in hideous grimaces, their dead eyes glaring at this profaning alien who dared intrude upon the waters of this river of the dead—a horrid escort, pregnant with dire forebodings and with menace.
Though he advanced very slowly, he tried always to take steps of about the same length; so that he knew that though considerable time had elapsed, yet he had really advanced no more than four hundred yards when ahead he saw a lessening of the pitch-darkness, and at the next turn of the stream his surroundings became vaguely discernible. Above him was an arched roof and on either hand walls pierced at intervals by apertures covered with wooden doors. Just ahead of him in the roof of the aqueduct was a round, black hole about thirty inches in diameter. His eyes still rested upon the opening when there shot downward from it to the water below the naked body of a human being which almost immediately rose to the surface again and floated off down the stream. In the dim light Bradley saw that it was a dead Wieroo from which the wings and head had been removed. A moment later another headless body floated past, recalling what An-Tak had told him of the skull-collecting customs of the Wieroo. Bradley wondered how it happened that the first corpse he had encountered in the stream had not been similarly mutilated.
The farther he advanced now, the lighter it became. The number of corpses was much smaller than he had imagined, only two more passing him before, at six hundred steps, or about five hundred yards, from the point he had taken to the stream, he came to the end of the tunnel and looked out upon sunlit water, running between grassy banks.
One of the last corpses to pass him was still clothed in the white robe of a Wieroo, blood-stained over the headless neck that it concealed.
Drawing closer to the opening leading into the bright daylight, Bradley surveyed what lay beyond. A short distance before him a large building stood in the center of several acres of grass and tree-covered ground, spanning the stream which disappeared through an opening in its foundation wall. From the large saucer-shaped roof and the vivid colorings of the various heterogeneous parts of the structure he recognized it as the temple past which he had been borne to the Blue Place of Seven Skulls.
To and fro flew Wieroos, going to and from the temple. Others passed on foot across the open grounds, assisting themselves with their great wings, so that they barely skimmed the earth. To leave the mouth of the tunnel would have been to court instant discovery and capture; but by what other avenue he might escape, Bradley could not guess, unless he retraced his steps up the stream and sought egress from the other end of the city. The thought of traversing that dark and horror-ridden tunnel for perhaps miles he could not entertain—there must be some other way. Perhaps after dark he could steal through the temple grounds and continue on downstream until he had come beyond the city; and so he stood and waited until his limbs became almost paralyzed with cold, and he knew that he must find some other plan for escape.
A half-formed decision to risk an attempt to swim under water to the temple was crystallizing in spite of the fact that any chance Wieroo flying above the stream might easily see him, when again a floating object bumped against him from behind and lodged across his back. Turning quickly he saw that the thing was what he had immediately guessed it to be—a headless and wingless Wieroo corpse. With a grunt of disgust he was about to push it from him when the white garment enshrouding it suggested a bold plan to his resourceful brain. Grasping the
