Little Gray astonished and delighted his young master that evening and covered himself with glory. He proved to be very swift, and Oscar was not long in making up his mind that he had nothing to fear.

When he was fully satisfied on this point his alarm gave way to an intense desire to make a specimen of the savage beast that had so nearly been the death of him.

He still carried his double-barrel in his hands—he was somewhat surprised to find it there, and wondered how he had managed to hold fast to it when he so narrowly escaped being thrown from his saddle, and terror had rendered his muscles so weak that he could scarcely sustain his own weight—but the heavy shot with which it was loaded would have made little impression upon the buffalo. They would have added to his fury, but they would not have checked his headlong rush. The only thing Oscar could do was to alarm the camp and obtain McCann's assistance.

The latter was a dead shot with the rifle—at least he had often said he was—and it would be no trouble at all for him to bring the buffalo down at the distance of a hundred yards, even though he were moving at the top of his speed. With these thoughts in his mind Oscar began shouting with all the power of his lungs:

"McCann! McCann! Bring a rifle out here and shoot this buffalo! I wish I could shoot him myself to pay him for the scare he gave me," he added mentally; "but if I ride to the wagon to get a rifle he will be sure to follow me there, and mercy knows what damage he wouldn't do if he got in among the oxen. All I can do is to lead him close enough to the grove to give McCann a fair chance at him. McCann, are you deaf? Bring a rifle out here and shoot this buffalo!"

A few moments later Oscar had the satisfaction of knowing that his wild calls for help had been heard.

The dogs set up a yelp, and came through the grove in a body; but the only man he could see was Big Thompson, who followed close after the pack, carrying a bunch of assegais in his hand.

Excited as he was, Oscar told himself that he had never seen a human being run as that Kaffir did. If he had lived in a civilized country he could have made his fortune on the race-track.

The dogs dashed at the buffalo at once, and quickly diverted his attention from Oscar, who drew up his horse and stopped to see the fight.

The huge beast charged right and left at his nimble assailants, which easily kept out of his way, and during one of these charges he caught Oscar's wind and made another dead set at him.
