"What are you doing in M'wa-lot's country?" demanded the gorilla man.

"I come as a friend," replied Tarzan. "I have no quarrel with your people."

The fellow had lowered his club now, and from other trees had come a score more of the shaggy creatures until the surrounding limbs sagged beneath their weight.

"How did you learn the language of the Sagoths?" demanded the bull. "We have captured gilaks in the past, but you are the first one who ever spoke or understood our language."

"It is the language of my people," replied Tarzan. "As a little balu, I learned it from Kala and other apes of the tribe of Kerchak."

"We never heard of the tribe of Kerchak," said the bull.

"Perhaps he is not telling the truth," said another. "Let us kill him; he is only a gilak."

"No," said a third. "Take him back to M'wa-lot that the whole tribe of M'wa-lot may join in the killing."

"That is good," said another. "Take him back to the tribe, and while we are killing him we shall dance."

The language of the great apes is not like our language. It sounds to man like growling and barking and grunting, punctuated at times by shrill screams, and it is practically untranslatable to any tongue known to man; yet it carried to Tarzan and the Sagoths the sense that we have given it. It is a means of communicating thought and there its similarity to the languages of men ceases.
