He could not see his companion, but he could hear his breathing. He wondered with whom fate had cast him in this remote dungeon of the city of gold.

THE MAN WHO STEPPED ON A GOD

Now that the torches were gone the room was very dark, but Tarzan lost no time in starting to investigate his prison. First he groped his way to the door, which he found to be constructed of solid planking with a small, square hole cut in it about the height of his eyes. There was no sign of lock or latch upon the inside and no way of ascertaining how it was secured from the outside.

Leaving the door, Tarzan moved slowly along the walls, feeling carefully over the stone surface. He knew that the other occupant of the cell was sitting on a bench in one corner at the far end. He could still hear him breathing. As he examined the room Tarzan approached closer and closer to his fellow prisoner.

In the rear wall the ape-man discovered a window. It was small and high set. The night was so dark that he could not tell whether it opened onto the outdoors or into another apartment of the building. As an avenue of escape the window appeared quite useless, as it was much too small to accommodate the body of a man.

As Tarzan was examining the window he was close to the corner where the other man sat, and now he heard a movement there. He also noticed that the fellow's breathing had increased in rapidity, as though he were nervous or excited. At last a voice sounded through the darkness.

"What are you doing?" it demanded.

"Examining the cell," replied Tarzan.

"It will do you no good, if you are looking for a way to escape," said the voice. "You won't get out of here until they take you out, no more than I shall."
