“I certainly hope so, for you will get great pleasure from it.”

“Not to mention a broken neck or arm or leg,” he remarked with a chuckle. “Now I suppose you call this contrivance a biplane because it has double wings?”

“That is the reason.”

“And it seems to me,” he added, turning his head to one side and squinting, “the length is a little greater from the nose of the forward rudder to the end of the tail than between the wing tips?”

“You are correct again; there is a difference of about two feet.”

“The wings are curved a bit; I have read that that shape is better than the flat form to support you in air.”

“Experiments have proved it so.”

“And this stuff,” he continued, touching his forefinger to the taut covering of one of the wings, “is rubberized linen?”

“It is with our machine, though some aviators prefer other material.”

“Spruce seems to be the chief wood in your biplane.”
