Riding up beside the little animal it was an easy matter to drop the loop over his head and bring him down.

"There, that will teach you to run away," growled the boy, cinching the rope and dragging the unruly pony back to camp.

In the meantime the others, after considerable effort, had succeeded in securing the other plunging bronchos, more rope having been brought for the purpose, while Tad, breathing hard, staked down the frightened animal he had roped.

"Now we'll see how Mr. Bear is getting along," announced the Professor, as they turned back toward the camp, where the bear was still fighting desperately with the smouldering tent.

As they reached the scene they observed Professor Zepplin hurrying to his tent. He was back again almost at once.

"Just happened to think of my revolver," he explained.

"Think you can kill him with that?" asked Tad.

"I don't know. I can try. It's a thirty-eight calibre."

"Won't even feel it," sniffed Ned. "I've read lots of times that it takes a lot to kill a bear."

The Professor raised his weapon and fired at the spot where the tent appeared to be most active.
