It was the voice of Pete, but it came to Jack like a voice in a dream. Mingling with it came the triumphant roar of the grizzly.

Bruised and shaken by his fall, the boy managed somehow to get to his feet and began running stumblingly forward. Suddenly he stopped. What had become of Pete?

In the same instant his friend's unselfish bravery flashed across him. Pete meant to stay behind and deliberately sacrifice himself while Jack got a chance to escape.

Jack turned and began to run back.

"Pete, Pete, you shan't do it!" he cried desperately.

But even as he yelled he gave a shrill cry of mortal terror. The huge black form was upon the cow-puncher, and all Jack could see was its huge, hairy arms as they shot out to envelope Pete in their grip. Over and over rolled the two, as the bear missed its footing on the treacherous hillside and began toppling down toward the trail. In this predicament it still gripped tight to its prey, however.

Suddenly Jack gave another yell—a cry of exultation. An extraordinary thing had happened.

In its rolling plunge down the slope the bear had come within the radius of Maud's iron-shod hind hoofs. With a scream of mingled fear and mulelike defiance, those formidable weapons drove out as if impelled by steel springs.

Ker-flo-p-p-p!

Both of those terrible heels struck the grizzly fair and square in the top of his ferocious head. With a howl of agony he dropped the man from his deadly grip, and with the blood streaming from the deadly wound went tumbling and clawing in his death agony down the slope.
