“We’ll soon solve the mystery,” said Gillis. “Come here, boy,” he added kindly.

Bomba came shyly toward him.

“What is your name?” asked Gillis.

“Bomba,” was the reply.

“Bomba!” repeated Gillis, with a frown of perplexity. “That’s a queer name for a white boy. For you are white, aren’t you?”

“Yes,” replied Bomba proudly, as he drew aside the puma skin and exhibited his chest.

“And since you understand what I say to you, you must be either American or English,” pursued Gillis. “What is your other name?”

“I haven’t any,” was the reply. “I am Bomba.”

The men exchanged puzzled glances.

“Who are your folks?” put in Dorn.
