Suddenly one of them received the signal, and, with a whoop of delight, he lowered his head and ran at Jack like a Japanese wrestler or a mad bull. The boy saw he meant to butt him in the stomach, and if he did so he would suffer serious injury. Forewarned was forearmed in his case, and, leaping aside, he tripped the Indian as he shot by, and sent him sprawling on his hands and knees. The uproar was deafening, but the contest, it may be said, had only opened, and the young Sauk bounded to his feet as if made of India Rubber. His coppery face was aglow with passion, and, pausing but an instant, he made a second rush, though this time he kept his head up, and spread out his arms so as to prevent Jack escaping him.
