"Perhaps we can make them surrender," he whispered.

"Lako! lako!" said the negroes indignantly.

"Yes; we will try."

Makoko and the other two men grumbled, but Samba silenced them.

"It is Lokolobolo's order," he said.

He offered Jack his Mauser, but Jack refused it with a smile, taking one of the Albinis which had been removed from the canoe. With the four he concealed himself behind the bushes. He had already noticed that all traces of the recent incidents had been carefully obliterated.

"Em'one!"
