So engaged in watching Frank was the chief that he did not at once note the panting messenger who came tearing up to the royal party from the direction of the village in the rear.

Then, as his eye fell on the boy, for such he was, the chief spoke a few words to him sharply. The youth replied between gasps, more at length.

Watching the advancing warriors, who now had come to a halt in the middle of the plain, where they knelt and took cover behind their shields, only their round black heads and long lances showing above, the boys paid no attention to this by-play.

Not so Wimba, however, for as the messenger poured out his tale, he clutched Jack by an arm and, having obtained his attention, repeated hastily what was being said.

“Him bad tribe raid village,” he said. “Carry off cattle and women. Boy escape and make tell Chief Ruku-Ru.”

“What! Great Scott!”

“What’s that? What’s that?” cried Bob, excitedly. “Say, Jack, if raiders cleaned out the village, maybe they went after our camp, too.”

Frank, unhearing, continued to crank his camera.

Other cameras, thousands of feet of film, both taken and unused, clothing, gifts for various chiefs yet to be encountered, rifles and ammunition. These latter had been left behind, and the boys wore only their automatics. Above all, their radio apparatus had been left in camp. Clumsy handling might destroy it irreparably.

“Find out all you can, Wimba,” he commanded sharply. “Did the raiders go near our camp?”
