"Let's sneak back the way we came then," whispered Dick. "They haven't seen us yet." Simultaneously the two boys turned to retrace their steps and there, blocking the trail they had just trod, stood a huge, black warrior scowling savagely at them. In his hand was a sharp spear.
"Golly!" exclaimed Dick.
"Gee!" ejaculated Doc. "What shall we do?"
"We ought to be nice to him," said Dick.
"Good morning!" said Doc, politely, with a smile that was nothing if not strained. "Nice morning, isn't it?"
Zopinga, who had stood silent thus far, now broke into a torrent of words, not one of which the boys understood. When he had ceased, he again stood immovable.
"Well," remarked Dick, casually, "I guess we'd better be getting along back to the train. Come on, Doc," and he started to move along the trail past Zopinga. Instantly the sharp point of the spear was at the pit of his stomach. Dick stopped. Zopinga pointed toward the village with his left hand and prodded Dick with his spear.
"I guess he's inviting us to lunch," suggested Doc.
