Halting less than fifty feet away, he brought his rifle to a level and let fly. It was as impossible for him to miss as it was to inflict a mortal wound, and the ball meant for the skull of the brute found lodgment elsewhere.

The bear appeared to be in the act of rising partly on his haunches, when the report, and probably a sharp twinge in his shoulder, apprised him of what was going on at the rear. The contemplated feast was not to be without its unpleasant interruption.

He uttered a low growl and came straight for the two youths. Their rifles being of the magazine kind, they were prepared to open a bombardment, which they did without delay; but after a number of shots had been fired, and the mountainous animal continued to sweep down upon them, Warren called out:

"Let's run, Tim! we need a cannon to stop him; we must find some place to shelter us."

Not doubting that his comrade would instantly follow, Warren wheeled about and dashed off without paying heed to the direction; he had no time to make any calculations.

Despite the fall of snow, there were only two or three inches on the ground, just enough to interfere with rapid travelling. Young Starr had not taken a dozen steps, when his foot turned on a smooth stone and he pitched headlong, with his gun flying from his grasp. He was not hurt, and he bounded up again as if made of rubber. He supposed the animal, which can lumber along at a speedy gait despite its awkwardness, was on his heels, but the furtive glance over his shoulder showed nothing of him, and the youth plunged forward and caught up his weapon as may be said on the fly.

With its recovery came something like confidence again, and he turned about to learn how Tim Brophy was making out.

It was just like the plucky fellow not to dash after his comrade, but to stand his ground, when the most experienced and the bravest hunter in the world would have lost no time in increasing the distance between him and the brute. The latter had scared Billy half to death, and his master meant to punish him therefor, so he held his ground, and managed to send in another shot while the grizzly was approaching, but which did no more to check his charge than a wad from a pop-gun.

This reckless daring on the part of Tim would have brought disaster, but for an unexpected interference.

Billy, the pony, no sooner saw the terrible brute turn his back upon him and lumber off, than he understood that the way of escape for him had opened. His panic departed like a flash, and he plunged through the opening with a snort of triumph; but his line of flight took him of necessity along that followed by the grizzly himself, who was advancing to the assault of the brave young Irishman.
