"Then I'll try another tree," said Onthank, and he caught a branch, and clambered up into a tree quite similar to the other in which he had been besieged.

Tom would gladly have followed his example, but the branch was too high for him to reach readily, and the grizzly was too near to give him adequate time. Poor boy! He began to despair, and was at an utter loss what to do. To face round and fire at the foe seemed about all that was left him, but he wanted to reserve his fire to the last. He caught sight of another tree, of a larger trunk than the one which Onthank had ascended, and ran towards it, pursued by the grizzly. Then commenced a dodging game, which seemed to afford but a brief respite from destruction.

"This can't last long," thought poor Tom. "I suppose I must die."

In that brief time of peril many thoughts passed through his mind. To die at his age would be sad enough; but the thought that his expedition would be a failure, only involving his father deeper in difficulty and debt chiefly troubled him. The mortgage would be foreclosed, and his father and whole family deprived of their humble home. Onthank watched the boy's peril, unable to give him assistance. To do him justice he almost forgot his own danger in the more apparent and immediate peril of his young companion.

"Be careful!" he shouted, quite needlessly. "Don't let him grip you. Give it to him right in the eye."

Tom was so absorbed, and his mind so painfully occupied by his efforts to keep out of his enemy's clutches, that he was not conscious of the warning.

Active and alert as he was, the result was hardly a matter of doubt. He would tire sooner than the bear, and if he ran again he was sure to be overtaken. This, however, was what he did. Of course the grizzly instantly pursued him. Poor Tom breathed a prayer for help, though there seemed no chance of his prayer being answered; but sometimes God sends assistance when there seems no chance of escape.

The galloping of a horse was heard. There was a whirling sound, and Bruin, already within two yards of Tom, was jerked back, and brought to a stand-still by a lasso which wound about his neck. A shout caused Tom suddenly to turn his head, and to his joy he saw a mounted Mexican vaquero, who had brought him timely relief.

Bruin growled angrily on finding himself balked of his prey. He was not disposed to yield to his new antagonist. Rising and sitting on his haunches he began coolly to draw in the lasso, against the combined strength of man and horse. The muscular force of a big grizzly is simply enormous. Usually he is attacked from two sides, two lassos being thrown around him. For a single antagonist he is sometimes more than a match, as seemed likely in the present case. The rieta being attached to the pommel of the saddle, of course the bear, in pulling as he did, hand over hand, steadily brought the vaquero and his steed nearer. The horse, terrified, trembled in every limb, and tried to rear; but his strength was as nothing when opposed to the steady power of his massive antagonist.

Relieved from the immediate attentions of the grizzly, Tom did not continue to run, but stood still, and, forgetting his own peril, remained an excited spectator of the struggle between the bear and the vaquero.
