Then another shot rang out as Fred swung into action. It was at close range, and the charge of shot tore directly into the throat of the leading wolf, causing him to leap high into the air, and then fall over on his back. He plunged for a moment, sending the snow flying in every direction, and then lay still.

THE WOLF RECEIVED A BLOW THAT BOWLED HIM OVER.

Shocked evidently by the fate that had overtaken taken both of his companions, the third wolf came to a sudden halt. With eyes glaring fiercely, he snapped and then leaped for the nearest rocks.

"Shoot him, somebody! We want to get all three of them!"

Crack! Bang! went a rifle and a shotgun almost simultaneously, but the aim of the two marksmen was poor, and only a few scattering shots went through the tail of the wolf. Then, with a wild yelp, he disappeared behind the rocks, and that was the last seen of him. In the meantime, the wounded beast was snapping and snarling most ferociously. He sent a shower of loose snow toward the Rovers, and then made a desperate leap at Jack.

It was a time of dire peril, and no one realized it more than did the oldest Rover boy. He attempted to retreat, but to do so in snowshoes was too much for him, and over he went on his side in a deep bank of snow, almost disappearing from view.

"The wolf is on top of Jack!"

"Shoot him—but be careful and don't hit Jack!"

"Don't fire!" gasped Randy. "You'll hit Jack sure!" and then, as well as he was able, he sprang to the front, using his gun as a club as he did so. Around came the stock with a wide swing, and the wolf received a blow in the side that bowled him over and over.
