"Don't you want to try it out?" he suggested. "I can show you how to fly it in a few minutes."

"I have flown one before," she told him. "But I would like to take it up for a few minutes if you don't mind. Am I to have this particular one? I have a certified check in payment."

The salesman blinked his eyes in further consternation. The check right there, the girl ready to take the plane home with her! It was a moment before he could catch his breath.

"Of course," he finally managed to answer. "I'll have her started for you immediately. And—would your friends care to go up with you?"

"Sure!" exclaimed Ted. "We're your best friends, aren't we, Linda? So oughtn't we to be privileged with the first ride?"

"You certainly are!" replied the famous aviatrix, squeezing Louise's hand in her excitement and delight. "Come on!"

It was the Mackays' first flight in an autogiro, and though they were very much crowded in the passenger's cock-pit, they insisted that that only added to the fun. With a sureness which Ted watched in admiration, Linda took off and flew round and round the field, putting the new plane through all sorts of tests, proving conclusively that all the claims for it were well-founded.

Fifteen minutes later they came slowly down to earth, landing on the exact spot from which Linda had taken off.

"Unscramble yourselves!" she cried to her passengers, as she climbed out of the cock-pit. "Let's go pay our bill."

"She's great, Linda!" approved Louise, as her husband helped her out. "I'm for her, even if she is a funny-looking bug."
