The man attempted to reply, but his words were unintelligible gibberish, then he shook his head and growled. Ras Thavas took a step towards him and the man dropped to all fours, his knuckles resting on the floor, and backed away, growling. “Come!” cried Ras Thavas. “We will not harm you.” Again he attempted to approach the subject, but the man only backed quickly away, growling more fiercely; and then suddenly he wheeled and climbed quickly to the top of the highest shelf, where he squatted upon a corpse and gibbered at us. “We shall have to have help,” said Ras Thavas and, going to the doorway, he blew a signal upon his whistle. “What are you blowing that for?” demanded the man suddenly. “Who are you? What am I doing here? What has happened to me?” “Come down,” said Ras Thavas. “We are friends.” Slowly the man descended to the floor and came towards us, but he still moved with his knuckles to the pavement. He looked about at the corpses and a new light entered his eyes. “I am hungry!” he cried. “I will eat!” and with that he seized the nearest corpse and dragged it to the floor. “Stop! Stop!” cried Ras Thavas, leaping forward. “You will ruin the subject,” but the man only backed away, dragging the corpse along the floor after him. It was then that the attendants came and with their help we subdued and bound the poor creature. Then Ras Thavas had the attendants bring the body of the ape and he told them to remain, as we might need them. The subject was a large specimen of the Barsoomian white ape, one of the most savage and fearsome denizens of the Red Planet, and because of the creature’s great strength and ferocity Ras Thavas took the precaution to see that it was securely bound before resurgence. It was a colossal creature about ten or fifteen feet tall, standing erect, and had an intermediary set of arms or legs midway between its upper and lower limbs. The eyes were close together and non-protruding; the ears were high set, while its snout and teeth were strikingly like those of our African gorilla. With returning consciousness the creature eyed us questioningly. Several times it seemed to essay to speak, but only inarticulate sounds issued from its throat. Then it lay still for a period. Ras Thavas spoke to it. “If you understand my words, nod your head.” The creature nodded. “Would you like to be freed of your bonds?” asked the surgeon. Again the creature nodded an affirmative. “I fear that you will attempt to injure us, or escape,” said Ras Thavas. The ape was apparently trying very hard to articulate and at last there issued from its lips a sound that could not be misunderstood. It was the single word no. “You will not harm us or try to escape?” Ras Thavas repeated his question. “No,” said the ape, and this time the word was clearly enunciated. “We shall see,” said Ras Thavas. “But remember that with our weapons we may dispatch you quickly if you attack us.”
