Then taking out a small but powerful galvanic battery, he arranged it and placed wires into the hands of the two men nearest to him in the great circle.
"Now," he said, "when I clap my hands you will find that you are all obliged to jump up." He gave the signal.

Frank turned on the battery, and in an instant the two hundred men and women, with a wild shriek, either leapt to their feet or rolled backward on the ground.

In another minute not a native was to be seen, with the exception of the chief, who had not been included in the circle.
