As Thure spoke Bud's lasso shot through the air; and the loop glided swiftly over the great head and tightened suddenly around the hairy neck, just at the moment the bear came to the decision to charge Thure and sprang toward him, with the result that the sudden unexpectedness of the jerk of Bud's rope yanked him off his feet and hurled him on his back. Thure instantly saw his opportunity and before the huge beast could right himself, he had swiftly cast the loop of his rope around one of the sprawling hind legs and drawn it tight. "Hurrah! We've got him!" yelled Bud triumphantly, as Gray Cloud whirled about and stood facing the grizzly, his strong body braced backward so that he held the rope taut, as all well-broken California horses were trained to do the moment the thrown rope caught its victim. "Got him! You bet we've got him!" echoed Thure, as his own horse whirled into position, with both front legs strongly braced, and drew the lasso tight about bruin's hind leg, thus stretching him out between the ends of the two reatas. But they had not "got him"--not yet; for, just at that moment, all the ferocious bulk of raging bone and muscle that had given _El Feroz_ his name of terror, gave a tremendous heave, whirled over on its feet; and, before either boy knew what was happening, Bud's lasso broke and about a ton of angry bear was hurling itself toward Thure. The unforeseen mischance had happened with a vengeance! Bud uttered a yell of warning and horror and caught at his rifle; but, almost before his hands could touch the gun, _El Feroz_ was upon Thure and only a tremendous jump sideways of his brave little horse saved him from the sweep of one of those saber-armed paws. The grizzly bear, for an animal of his huge bulk, is astonishingly agile and speedy, when once his fighting blood is aroused; and, if ever a grizzly was fighting mad, that grizzly was now _El Feroz_. The instant he saw that he had missed the horse and man, he whirled about and was after them again; and, so swift was his turn and so sudden his charge, that, once again, only the superior horsemanship of Thure and the agility of the horse saved them from a sweeping blow of one of the great paws that came so close that Thure could feel the rush of its wind against his face. "Out run him! Out run him!" yelled Bud excitedly. "Try to throw him with your rope; and I'll see if I can get a bullet in him," and he suddenly jerked up Gray Cloud, so that he could make his aim more sure, threw his rifle to his shoulder, and fired.
