But Orissa could not sleep. She lay and dreamed of the great triumph before them; of the plaudits of enraptured spectators; of Stephen’s name on every tongue in the civilized world; and, not least by any means, of the money that would come to them. No longer would the Kanes have to worry over debts and duebills; the good things of the world would be theirs, all won by her brother’s cleverness.

If she slept at all before the gray dawn stole into the sky the girl was not aware of it. By half past four she had smoking hot coffee ready for Steve and herself and after hastily drinking it they rushed to the hangar.

Steve was bright and alert this morning and declared he had “slept like a log.” He slid the curtains away from the front of the shed and solemnly the boy and girl wheeled the big aëroplane out into the garden. By careful manipulation they steered it between the trees and away to the fence of Marston’s pasture, which adjoined their own premises at the rear. To get it past the fence had been Steve’s problem, and he had arranged to take out a section of the fencing big enough to admit his machine. This was now but a few minutes’ work, and presently the aëroplane was on the smooth turf of the pasture.

They were all alone. There were no near neighbors, and it was early for any to be astir.

“One of the most important improvements I have made is my starting device,” said Steve, as he began a last careful examination of his aircraft. “All others have a lot of trouble in getting started. The Wright people erect a tower and windlass, and nearly every other machine uses a track.”

“I know,” replied Orissa. “I have seen several men holding the thing back until the motors got well started and the propellers were whirling at full speed.”

“That always struck me as a crude arrangement,” observed her brother. “Now, in this machine I start the motor whirling an eccentric of the same resisting power as the propeller, yet it doesn’t affect the stability of the aëroplane. When I’m ready to start I throw in a clutch that instantly transfers the power from the eccentric to the propeller—and away I go like a rocket.”

As he spoke he kissed his sister and climbed to the seat.

“Are you afraid, Steve?” she whispered, her beautiful face flushed and her eyes bright with excitement.

“Afraid! Of my own machine? Of course not.”
