“That if they manage to keep him prisoner we shan’t see him again till I have given them the plans to the location of the Dangerfield treasure cave.”

“They wouldn’t dare——” began the professor. But the major interrupted him.

“We have already had a proof of what they will dare,” he said, “they are as desperate a band of ruffians as I have ever heard of.”

In the meantime the canoes sped on through the night. Rob mentally tried to keep some track of the distance traversed, but he was totally unable to do so. He judged, however, when the paddles finally ceased their splashing, that they must have come some distance, for it was day-break when the canoes came to a halt.

“Ah ain’t no niggah. Ah’s a ’spectabilious colored gent”; protested Jumbo, “’nd I kain’t shut mah haid nohow ’cos it keeps openin’ an’ shuttin’ of its own accord whar you busted me on it.”
