For a moment, Jack and the bear studied each other attentively. It was a wonderfully short moment, however. Jack, uttering an exclamation, managed to turn and shoot a glance over his shoulder. To his amazement, he saw Bob Somers approaching on foot at top speed and five horsemen fighting to control their bronchos.

"Thunderation!"

The black bear, having evidently come to the conclusion that Jack was responsible for all his misfortunes, gave an angry snarl, opened his mouth to show a row of perfect teeth, and began to lumber forward.

Jack wasn't quite sure whether he had been badly injured or not, but decided that the time to find out hadn't come. Pains and aches seemed to drop away as easily as the dust from his shoulders when he scrambled to his feet with a lusty yell and fled.

The enemy, apparently satisfied at this tribute to his power, came to a halt, raised his shaggy head and gazed curiously at the horsemen; then, uttering a grunt of extreme disapproval, plunged away.

"Hurt, Jack?" called Bob, breathlessly.

"Hurt?" yelled the others.

Jack stopped his flight abruptly.

Now that all danger, as well as suspense, was over, shooting pains in various parts of his anatomy began to make themselves felt with a force that caused him to wince.
