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 attempt 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 Gallos, 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 sign 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 shtiftas; "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 had escaped upon one of their horses. 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 valour, they withdrew to the rude shelters they had constructed and left the night to Tarzan, Numa, and a single sentry.
