Had Rob started a moment sooner he would have escaped, but in his desperate haste he fell headlong, and the ox bounded directly over his body, fortunately, without touching him.

The other animals were unequal to the draught upon their courage, and diverged sharply, some to the right and the rest to the left, circling back over the plateau on whose margin Jack Cosgrove and Docak were waiting until they came within certain range.

"Fred, fire quick! my gun's unloaded!" called Rob from where he lay on the ground; "don't wait a second or it'll be too late!"

Fred did fire, sending the bullet with such accuracy that it wound up the business. Precisely the same catastrophe, described by the Esquimau to the sailor took place. The ox, coming with such desperate speed, was carried forward by its own terrific momentum. It may be said that he was dead before he could fall; he certainly was unconscious of what he was doing, for he crashed against the rocks, as if driven from an enormous catapult and then collapsed, in a senseless heap, with his flat horns smashed and broken to fragments.

Fred Warburton saw that his "turn" had arrived, and he made the most of it. Rob had been merciless to him, and he was now ready to pay him off in his own coin.

"I wouldn't lie down there, Rob," he said, gravely, "for the ground must be cold."

"It does seem rather chilly—that's a fact," replied his friend, who, knowing what was coming, slowly climbed to his feet; "I didn't think of that when I lay down."

"What made you lie down at all?"

"You see I noticed that the creature didn't mean to turn about and travel the other way as yours did; there was the difference. Then I knew, too, that he must be tired from running so hard, and it struck me as a kind thing to do to serve as a rug or carpet for him."

"You did so, and no mistake. If I'm not in error," continued Fred, with a quizzical expression, "I heard you call out a minute ago something about my hurrying up and firing so as to save your life."
