"Let's sue her!"

"Now, Lou! You are positively vindictive. And all because she made fun of my flying." But Linda gave her chum a hug; it was so comforting to feel her entire loyalty.

"All right, then let's forget her.... Can you stay for dinner, Linda?"

"No thank you, Lou—I'm afraid not. Daddy's home, and he may leave any minute. You know I told you he's in business now in New York."

"Yes, it seems funny, doesn't it? I never could imagine your father in business. What do you suppose made him do that?"

"Restlessness, I think, and the fact that he can't ride any more. Besides, he told me the ranch doesn't pay, so I guess he has to try something else."

"Well, if you will have airplanes, and expensive courses——" teased Louise.

"Oh, but just wait! We'll be ten-thousand-dollar-a-year women when we finish our education, Lou. It's going to be a good investment."

"I certainly hope so.... Well, so long. I'll call you up tomorrow and we'll go shopping for our overalls."

Linda drove off, and arrived just in time for dinner. Her aunt, it seemed, had been impatiently awaiting her return, for she had learned from Linda's father that he had given his consent to the ground school course.
