Thus it was that when the opportunity occurred for this diversion in the form of a little friendly rivalry, each set off in the highest of spirits.

Holden at once plunged into the thickest part of the bush at the back of the little camp-ground. Arnold decided to follow the downward course of the stream, in the hope that it might lead to a lake or pool where duck might fall to his lot.

Pushing his way through the scrub that bordered the running water, Bob went some distance without any success. Then he heard the sound of a gun some way to the rear, and he smiled to himself, as he thought that his chum had already commenced operations.

Spurred on by the thought, the boy hastened his steps, and increased his vigilant scrutiny of the bush for the first signs of game. But luck did not come his way for some time, and his anxiety not to be beaten in the contest led his feet farther than the half-hour's limit merited.

It was not until he had tramped a mile or more that Bob realised how quickly the time had passed. It was disappointing to have to return empty-handed to the camp, especially since he had heard Alf's gun crack twice again. At the same time, if there were no creatures to be shot, he could not be reproached for his lack of success.

With a rueful grimace and a laugh of amusement at his own failure, the boy was just turning to retrace his steps, when suddenly the bush rustled at his side, and a brown body leapt into the air as if it had been shot from a catapult.

"Antelope!" Bob exclaimed with delight, and quick as a flash of light the butt of his gun darted to his shoulder and the woods resounded with the explosion of a cartridge.

It was a quick aim and not too good, for the animal disappeared in the farther bush, and the cracking of twigs told the young hunter that the quarry was yet active.

"This is worth waiting for," said Bob to himself, as he rushed forward in pursuit. "A dozen of Alf's prairie chicken will not be equal to an antelope—if I get him!"

There was much in that little "if," for evidently the deer was far from being disabled, since it had so rapidly made distance between itself and the hunter.
