The other looked at him in astonishment.

"What! You fly?"

"No; but I can learn."

"Then I will learn too," said Gaspard with dignity. "We meet—in six months?"

"Good." Jacques pointed to the ceiling. "Say three thousand feet up."

"Three thousand four hundred," said Gaspard for the sake of disagreeing.

"After all, that is for our seconds to arrange. My friend Epinard of the Roullens Aerodrome will act for me. He will also instruct me how to bring serpents to the ground."

"With the idea of cleansing the sky of cauliflowers," said Gaspard, "I shall proceed to the flying-ground at Dormancourt; Blanchaille, the instructor there, will receive your friend."

He bowed and walked out.

Details were soon settled. On a date six months ahead the two combatants would meet three thousand two hundred feet above the little town in which they lived, and fight to the death. In the event of both crashing, the one who crashed last would be deemed the victor. It was Gaspard's second who insisted on this clause; Gaspard himself felt that it did not matter greatly.
