Perfunctorily the numbers of the slaves were taken, as they passed in, and entered in a great book; but to Tarzan's relief he noted that no attention was paid to the guards, who moved along beside their charges and down into the interior without being checked or even counted, and with them went Komodoflorensal, Prince Royal of Trohanadalmakus, and Tarzan of the Apes. Once inside the quarry and past the guard room the two fell gradually to the rear of the column, so that when it turned into a level above that which they wished to reach they were enabled to detach themselves from it without being noticed. To leave one column was but to join another, for there was no break in them and often there were several moving abreast; but when they reached the thirty-fifth level and entered the tunnel leading to the chamber in which Talaskar was confined they found themselves alone, since there is little or no activity in these corridors leading to slave quarters except early in the morning when the men are led forth to their labors and again at night when they are brought back. Before the door of the chamber they found a single warrior on guard. He was squatting on the floor of the tunnel leaning against the wall, but at their approach he rose and challenged them. Komodoflorensal, who was in the lead, approached him and halted. "We have come for the slave girl, Talaskar," he said. Tarzan, who was just behind Komodoflorensal, saw a sudden light leap to the eyes of the warrior. Was it recognition? "Who sent you?" demanded the warrior. "Her master, Zoanthrohago," replied the Trohanadalmakusian. The expression upon the face of the warrior changed to one of cunning. "Go in and fetch her," he said, and unbolted the door, swinging it open. Komodoflorensal dropped upon his hands and knees and crawled through the low aperture, but Tarzan stood where he was. "Go in!" said the guard to him. "I will remain where I am," replied the ape-man. "It will not require two of us to find a single slave girl and fetch her to the corridor." For an instant the warrior hesitated, then he closed the door hurriedly and shot the heavy bolts. When he turned toward Tarzan again, who was now alone with him in the corridor, he turned with a naked sword in his hands; but he found Zuanthrol facing him with drawn rapier. "Surrender!" cried the warrior. "I recognized you both instantly." "I thought as much," said Zuanthrol. "You are clever, with the exception of your eyes--they are fools, for they betray you." "But my sword is no fool," snapped the fellow, as he thrust viciously at the ape-man's breast.
