"Good. Now this is a drag wire."
After twenty minutes of this kind of thing he asked her to point out an aileron and explain its use.
"K.O." he said at last. "We'll go over parts each day for a while and the book work you must do at home will help to refresh your memory. Now nip into the forward cockpit and I'll explain the working of the controls."
He gave Dorothy a hand up and when she was seated, swung himself on to the cowl of the cockpit.
"First of all--and let this become habit--" he ordered, "adjust your safety belt. Yes, that's the way. Now we'll go ahead. That's the stick there. Take hold of it. You'll notice it is pivoted at its base. Forward movement of the stick increases the angle of attack of the elevators and depresses the nose. Backward movement decreases angle and raises the nose. Lateral movement of the stick operates the ailerons, movement to the right depressing the right wing, and to the left, the left wing."
When she was sure she understood the functions of one thing he explained the next.
"Now tell me just what I have told you--" he commanded.
Fully an hour had gone by before he was satisfied that she understood thoroughly.
"Tired?" he asked at last.
"Not a bit," she smiled. "I'm afraid I'm kind of dumb--but all these gadgets, as you call them, are a little confusing at first."
