The old man leaned his head upon his hands, while his elbows rested on his knees. It was impossible for him to sit upright. His hair was white, and his face wrinkled; he looked his age. Certainly he was a different person from what Torrence had expected.
"I suppose you have brought a model with you," continued Wetherbee; "you Yankees are so handy with such things." This was evidently intended as a compliment.
"No," said Torrence, "I did not suppose it was necessary. The transportation would have been costly, and I knew that if you insisted, it could be shipped after me. My last effort was deficient in some minor details, which would have necessitated a thorough overhauling of the parts, with readjustment. My position now is that of absolute mastery of the subject, and I thought, with your assistance, that I might build a full-sized vessel at once. There is no longer any need to waste money on models, as the next machine will fly, full size."
Mr. Wetherbee lifted his head a little.
"How can you be sure of it?" he asked.
"Because my last model did," answered Torrence.
"And yet you admit there was an error."
"There was a slight error of calculation, which impaired the power I hoped to evolve; but I know where the mistake lay and can remedy it. All my plans and formulas are with me. There is no vital principle at stake. The thing is assured beyond a doubt."
"And what would be the size of the vessel you propose to build?" asked Wetherbee.
"My idea is to construct a ship for practical aerial navigation, capable of carrying half a dozen passengers, with their luggage. Such a vessel would be about sixty feet long, with ten feet beam; while her greatest depth would be about eleven feet."
