As he watched the camp, seeking for some suggestion as to how he might most annoy or inconvenience the bandits, it occurred to Tarzan that a just reprisal would consist in taking from them something that they wanted, just as they had deprived him of the buck he had desired. Evidently they wished the prisoner very much or they would not have gone to the trouble of securing him so carefully; so this fact decided Tarzan to steal the white man from them. Perhaps curiosity also had a considerable part in inducing this decision, for the strange apparel of the prisoner had aroused within the ape-man a desire to know more concerning him.
To accomplish his design, he decided to wait until the camp slept; and settling himself comfortably in a crotch of the tree, he prepared to keep his vigil with the tireless patience of the hunting beast he was. As he watched, he saw several of the shiftas attempting to communicate with their prisoner; but it was evident that neither understood the other.
Tarzan was familiar with the language spoken by the Kafichos and Gallas, and the questions that they put to their prisoner aroused his curiosity still further. There was one question that they asked him in many different ways, in several dialects, and in signs which the captive either did not understand or pretended not to. Tarzan was inclined to believe that the latter was true, for the sign language was such that it could scarcely be misunderstood. They were asking him the way to a place where there was much ivory and gold, but they got no information from him.
"The pig understands us well enough," growled one of the shiftas; "he is just pretending that he does not."
"If he won't tell us, what is the use of carrying him around with us and feeding him?" demanded another. "We might as well kill him now."
"We will let him think it over tonight," replied one who was evidently the leader, "and if he still refuses to speak in the morning, we will kill him then."
This decision they attempted to transmit to the prisoner both by words and signs, and then they squatted about the fire and discussed the occurrences of the day and their plans for the future. The principal topic of their conversation was the strange white giant who had slain three of their number and escaped upon one of their horses; and after this had been debated thoroughly and in detail for some time, and the three survivors of the encounter had boasted severally of their deeds of valor, they withdrew to the rude shelters they had constructed and left the night to Tarzan, Numa, and a single sentry.
The silent watcher among the shadows of the tree waited on in patience until the camp should be sunk in deepest slumber and, waiting, planned the stroke that was to rob the shiftas of their prey and satisfy his own desire for revenge. As he patiently bided his time, there came strongly to his nostrils the scent spoor of Numa, the lion; and he guessed that the carnivore, attracted by the presence of the horses, was coming to investigate the camp. That he would enter it, he doubted, for the sentry was keeping the fire blazing brightly; and Numa seldom dares the fearful mystery of flames unless goaded by extreme hunger.
At last the ape-man felt that the time had come when he might translate his plan into action; all but the sentry were wrapped in slumber, and even he was dozing beside the fire. As noiselessly as the shadow of a shadow Tarzan descended from the tree, keeping well in the shadow cast by the beast fire.
For a moment he stood in silence, listening. He heard the breathing of Numa in the darkness beyond the circle of firelight, and knew that the king of beasts was near and watching. Then he looked from behind the great bole of the tree and saw that the sentry's back was still turned toward him. Silently he moved into the open; stealthily, on soundless feet, he crept toward the unsuspecting bandit. He saw the matchlock across the fellow's knees; and for it he had respect, as have all jungle animals that have been hunted.
