The priest was looking in astonishment from his god to the stranger who spoke to him with so little reverence and who held an end of the rope tied about the god's neck. With horror, he had even seen the creature jerk the rope.

"Go, Father Tobin," said the gorilla god, "and gather the faithful."

"And see that there is no treachery," snapped Tarzan. "I have your god's promise to help me save that girl. You see this rope about his neck? You see this knife at my side?"

The priest nodded.

"If you both do not do all within your power to help me your god dies." There was no mistaking the sincerity of that statement.

"Go, Father Tobin," said the gorilla god.

"And hurry," added Tarzan.

"I go, My Lord," cried the priest; "but I hate to leave you in the clutches of this creature."

"He will be safe enough if you do your part," Tarzan assured him.

The priest knelt again, crossed himself, and departed. As the door closed after him, Tarzan turned to his companion. "How is it," he asked, "that you have been able to transmit the power to speak and perhaps to reason to these brutes, yet they have not taken on any of the outward physical attributes of man?"
