“He was angry because we refused to give him a half interest in the aircraft,” she explained. “So I simply quit and came home.”

Steve sat down and stared at her a moment. He had been thinking of Mr. Cumberford’s warning ever since that strange individual had gone away, and Orissa’s “resignation” afforded him distinct relief.

“I’m glad of it, Ris,” he said, earnestly. “There’s no necessity for you to work now, for we have plenty of money to see us through. Besides, I need you here to assist me.”

“Really, Steve?”

“It’s a fact. I don’t like to employ outside assistance at this stage of the game; it might be fatal. But you are nearly as well posted on aëroplanes as I am, Orissa, and you’re clever enough to be of real help to me. I don’t need brute strength, you know.”

“Why, I’m terribly strong!” she said with a gay laugh, baring her round arm and bending her elbow to show how the muscle bunched up. “I can lift as much as you can, Steve, if it is necessary.”

“It won’t be necessary,” replied her brother, delighted to find how easily she adopted his suggestion. “Just grab the end of that bow and hold it steady while I shave a point to it. That’s it. Don’t you see how awkward it is for me to handle these things alone?”

She nodded.

“You’re right, Steve. I’ll stay at home and help you finish the aircraft,” said she.
