Rejoining the group who had been watching them, Kiwi’s face was wreathed in smiles.

Armbruster called out to the Skipper, “How about testing this pupil for me, Captain?”

Dad shook his head as he said, “I’d rather some one else did. Let Jack take him and give the final word.”

So Jack put on his helmet and goggles, climbed into the front seat and called back to Kiwi:

“All right! Take me up for a ride.”

Kiwi took the plane off beautifully, circled both to the right and to the left, put the plane into a spin and recovered from it, and amply proved to Jack that he was fit to go up alone. As they came down Jack called to him:

“You’ll do, Kiwi! Armbruster has done another good job!”

As the plane drew up to where Dad and Armbruster were standing, Jack stopped the motor and said to Kiwi:

“As soon as the air gets a little quieter I should think you could take it up alone.”

Here Armbruster cut in, “Don’t you think the boy does very well for the few lessons he’s had?” And Jack agreed with him.
