"It won't do any harm, I suppose," the captain replied, and an instant later they all fired together, emptying their revolvers as rapidly as they could pull the triggers. By this time the small boats were spread out in a semicircle and as the shots rang out, the paddlers stopped as though undecided whether to keep on or to turn back. But, after a few moments of indecision, evidently noting that no one had received an injury, the leader shouted an order and the paddlers resumed their work.

"Reckon we'll have to make a hit or two next time," the captain announced grimly. "That didn't seem to impress them much."
