But the circus people had gone through dangers like this before, and they knew what to do. Under the direction of Jim Tracy and his helpers, extra poles were quickly put in place to take the weight of the wet canvas off the broken one. This at once raised the tent up from those on whom it had partly fallen.

And then something else happened.

One of five horses which were being put through a series of tricks by a man trainer, suddenly bolted out of the ring. Joe, high up in the tent, saw him running, and noted that the animal was headed for the ring where Helen Morton was performing with Rosebud.

"He's going to run into her!" thought Joe. "I've got to do something!"

He must think and act quickly. While attendant's were running after the bolting horse Joe, looking down, saw that the animal would pass close to his life net. In an instant Joe had decided what to do.

He poised on the small platform, from which he made his swings, and dropped straight into the big net. Just as he had calculated, he bounced up again, and as he did so he sprang out to one side.

Joe's quick eyes and nerves had enabled him to judge the distance correctly. He leaped from the net just as the horse was opposite him, and landed on his back in a riding position.

It was the work of but a second to reach forward, grasp the little bridle which the animal wore, and pull him to one side.

And it was not a second too soon, either, for the horse was on the edge of the ring in which Helen was performing with Rosebud. If the maddened animal had gone in, there would have been a collision in which the girl performer would, undoubtedly, have been injured.

"Good work, Joe!" cried the ring-master. "But there's plenty more to be done. I guess we'll have to get all the men performers to help hold down the tent. I'm afraid she's going."
