"Yes."

"And another thing. While you're moving on the bar, just remember to do it quietly and easily. You've seen the two Japs at work in the show, I know. When the big fellow balances the pole on his shoulder, and the little fellow goes up, every move is made as though there would be a smash if they were not careful."

"I understand," said the girl.

The machine had been brought around and was heading toward the grounds. Matt twisted the small forward planes, which laid the course for ascending or descending. At the same time he speeded up the motor.

The Comet pointed upward; then, at the top of her course, was as quickly turned and aimed toward the earth.

Matt caught a glimpse of a sea of upturned faces. The machine was rushing downward at a frightful pace.

"Now!" shouted Matt.

He saw the girl poise birdlike on the foot-rest, then sink from it with the trapeze. So great was the slant of the aëroplane that she seemed to fall forward.

There was a jar as the bar reached the end of the ropes, and, with the girl's weight, was caught and held. The Comet made an erratic wabble and lurched sideways like a great bird, wounded on the wing.

Haidee withstood the jolt admirably, and Matt twirled the lever operating the steering planes.
