Up and up went the sky racer, until it was well over the town of Waterford, where Mr. Damon lived.

"There's his place!" yelled Ned, pointing downward. He had to yell to be heard above the noise of the motor. Tom nodded in reply. He, too, had picked out Mr. Damon's large estate. There were many good landing places on it, one near the house for which Tom headed.

The aeroplane shot downward, like a bird darting from the sky. Tom grasped the rudder lever more firmly. He looked below him, and then, suddenly he uttered a cry of terror.

"What is it?" yelled Ned.

"The rudder! The deflecting rudder! It's jammed, and I can't throw her head up! We're going to smash into the ground, Ned! I can't control her! Something has gone wrong!"

Blankly, and with fear in his eyes, Ned gazed at Tom. The young inventor was frantically working at the levers, trying to loosen the jammed rudder--the rudder that enabled the sky racer to be tilted upward.

"Can't you do it?" cried Ned.

Tom shook his head helplessly, but he did not give up. Madly he worked on, and there was need of haste, for every moment the aeroplane was shooting nearer and nearer to the earth.
