having overtaken the fugitive, he had lowered his head to impale the shrieking man upon his horns. With such startling abruptness did the huge beast collapse that the pursued officer did not realise the fact until he had run a farther distance of some thirty yards or so, and even then, when at length he halted and looked back at the prostrate and motionless animal, he seemed quite unable to understand that it was dead and harmless; for he shouted an order to his men to close in round the buffalo and secure it with cords before it recovered itself and resumed the aggressive. It was not until a few of the bolder spirits, having cautiously approached the carcass, nearly enough to perceive the bullet hole and the blood flowing from it, had satisfied themselves that the brute was in very truth dead, and had borne emphatic testimony to the extraordinary fact, that he was able to screw up his own courage to the point of personal investigation. Then he calmly made his way back to the road and, approaching Grosvenor, demanded an explanation of the seeming miracle; but even after he had been told, and the rifle exhibited to him and its powers laboriously explained, he seemed quite unable to understand, and was at last fain to dismiss the mystery with an impatient shrug of the shoulders, and an order for the march to be resumed. But Dick had seen a man tossed by the buffalo, and had judged, by the victim's shriek of agony, that he was badly hurt; he therefore kept his eyes open as they passed along the road, and sharply directed Grosvenor to call upon the officer to halt when presently they came upon a group of about a dozen persons standing by the side of the road surrounding a little group consisting of two persons, a man and a woman; the man bleeding profusely from a ghastly wound in the thigh, and already grey and sharp of feature under the shadow of death, while the woman crouched helplessly in the dust, supporting the wounded man's head upon her knees. Without ceremony Dick forced his way through the little crowd of onlookers, gave one keen glance at the prostrate man, and then, turning, shouted to Grosvenor: "This chap is bleeding to death, Phil--artery severed apparently. Just explain to our man, will you, and tell him that, with his permission, I propose to save the poor fellow's life. Mafuta, bring my medicine chest here, quick!"
