The moment Jack was close enough he bounded forward and made a sweeping blow, with the knife gripped in his right hand. Had the weapon struck where it was aimed, there would have been one Indian less before the spectators could have realized what had taken place. The other warriors were looking upon the picture as though in doubt of what was coming. Among those watching the scene was Otto Relstaub, whose eyes were riveted on his friend. The thrilling encounter had opened so suddenly that he fairly held his breath, certain that Jack would not live two minutes longer.
