“Why, Ridley,” retorted Parks, in a vaunting way, “I’ve got a boy here who can give you a handicap and double discount you.”

“Is that him?” inquired Ridley, with a stare at Andy.

“That’s him out of harness,” laughed Parks. “Like to see him do something?”

“Just to show you’re all bluster, I would,” answered Ridley.

“Machine in order?”

“True as a trivet.”

“Andy, give them a sample of a real bird diving, will you?”

“All right,” said Andy.

He had not been tutored by his skillful employer vainly. Andy was in excellent practice. He got into the clear, started up the Ridley machine, and took a shoot on a straight slant up into the air about one hundred and fifty feet.

A cry of surprise went up from the watching group as Andy suddenly let the biplane slide on a sharp angle towards the ground, shutting off the power at the same time.
