Holding rifle and powder-horn above his head, the hunter suddenly sunk down and swam rapidly into the opening. Just before the cave-mouth the water was several yards in depth.

Pausing just within the entrance, the hunter turned his face toward the eastern shore. He had not long to wait.

A man dashed through the undergrowth, sprung down the sandy bank, and ran rapidly across the level bar, stumbling at the water's-edge, falling at full length. From his cover, the hunter could see a knife-blade flash in the sunlight, and then the fugitive cast from him the severed part of an arrow that had pierced his leg.

Freed from this incumbrance, he arose and dashed through the shallow water toward the western shore. But several precious moments had been lost, and, with yells of vindictive exultation, nearly a score of savages sprung out upon the river-bank.

The fugitive heard their cries, and glanced back over his shoulder. He saw several of them with bended bows, and suddenly flung himself forward at full length in the water, at this point about knee-deep.

His ruse was successful. The barbed shafts passed over his head, burying themselves harmlessly in the sparkling water.

A loud voice from the bank gave utterance to several hasty words, and as though in obedience to it, half a dozen braves sprung toward the water, the remainder bending their bows ready for instant use in case the fugitive should arise to continue his flight.

With eager interest the white hunter watched this scene, though his countenance showed evident relief when he saw that the fugitive as well as pursuers were Indians. Though far from being one of that class termed Indian-haters, he bore the race little love, for they had dealt his heart more than one crushing blow.

Even at that distance, he could distinguish peculiarities that marked the pursuers as Osages, once the all-powerful rulers of that vast tract of country. Whether or no the fugitive belonged to the same tribe, he could not tell, owing to his so suddenly burying all but head and shoulders in the water.

Eagerly he watched the result. He saw a sudden movement of the hunted red-skin's arms. At the same moment the foremost savage flung aloft his hands, and fell backward, a feathered shaft quivering deep in his brain.
