"I know of only one bird — the parrot — that talks; and it can't fly very high."

"The machine had scarcely cleared the ground when it began to turn up, and the next instant it darted into the ground."

"We were not looking for a fortune, but we were looking for a solution."

"The course of the experiment was not always smooth. The machine would start all right, but the propelling power was not sufficient to overcome the resistance of the air."

"Learning the secret of flight from a bird was a good deal like learning the secret of magic from a magician—something the magician won't tell, and the bird can't tell."
