Fred was startled when he observed the failure, for his friends were too far away to give him support, and it was necessary to place another cartridge in the chamber of his weapon before it could be used. He proceeded to do so, without stirring a foot, and with a coolness which no veteran hunter ever excelled.

But if Fred stood still the musk ox was very far from doing so.

One glance only at the youth was enough, when, with a snort, he whirled about, galloped a few paces, and then wheeled with marked quickness, and faced the young hunter again. While engaged in this performance his snortings drew the attention of his companions, who, throwing up their heads, galloped to him, and the whole eleven speedily stood side by side, facing the point whence the attack had come.

They were of formidable appearance, indeed, for, with lowered heads, they pawed up the earth and began cautiously advancing upon the boy, who had his cartridge in place and was ready for another shot. But instead of one musk ox he was confronted by eleven!

"My gracious!" he said to himself; "this is a larger contract than I thought of. If they will only come at me one at a time I wouldn't mind. I wonder where the other folks are?"

He glanced right and left, but nothing was to be seen of Rob or Jack or Docak. It looked as if a line of retreat should be provided, and he ventured a glance to the rear.

He saw a mass of rocks within a hundred yards, against which a good deal of snow had been driven, and he concluded that that was the only available refuge, with no certainty that it would prove a refuge at all.

"Being as I shall have to fetch up there to save myself, and being that those beasts can travel faster than I, it wouldn't be a bad idea to begin edging that way now."

He would have been glad to whirl about and dash off, reserving his shot until he reached the rocks, but for his belief that such an attempt would be fatal to himself. Nothing encourages man or animal so much as the sight of a flying foe, and he was sure that he would instantly have the whole herd at his heels, and they would overhaul him too before he could attain his shelter.

It was a test of his nerves, indeed. There were eleven musk oxen, heads lowered, eyes staring, with low, muttering bellows, pawing and flinging the dirt behind them, while they continued advancing upon the motionless lad, who, having but one shot immediately at command, sought to decide where it could be sent so as to do the most good.
