"No; certainly not. He looks and is clever. If he says gusts don't matter, they don't," thought Andrew, after another sharp look at his nephew. "What appears difficult to believe may very well be simple when one has seen his designs. Here, Joe," he cried. "We get drifting on; do read that document, then show me your plans. I'll pay a cheque for ten thousand pounds into your account to-morrow, and then you'll be able to go ahead. Now, the document."

Joe picked it up from the table on which it was resting. Unfolding the sheet, he disclosed at the top the arms of the Hamburg-Amerika Steamship Company, and in the right-hand corner the name of the ship they had so recently left. The date was scrawled in a firm hand beneath it, and then there appeared the following words: "I, Andrew Provost, of Park St., Toronto, Canada, and of 29 Fenchurch St., London, England, guarantee to build with the help of my nephew, Joseph Gresson, and others whom I may appoint, an airship similar to the well-known Zeppelin; that is to say, when inflated with gas the said ship shall be lighter than air. It shall be capable of lifting not less than thirty tons, of progressing against a wind at more than sixty miles an hour, and of traversing the world in any direction, keeping in the air for that purpose as long as shall be necessary, though she may be allowed to descend to the land for necessary supplies, renewals, and repairs. Should I succeed with the help abovementioned in building a ship capable of all this, and of circling the world, and should that voyage be completed within nine months of this date, then Carl Eugene Reitberg, of 42 Park Lane, London, England, guarantees to pay the full cost of the building of the said ship, and of her voyage, but not exceeding in all one hundred thousand pounds. It is further agreed that a special form of passport shall be obtained from the Foreign Office, and that the same having been initialled by the various authorities of the countries over which the ship may pass in her voyage shall be held to be proof of her voyage."

"Clear as crystal. And you can do it?" asked Andrew.

"Certainly."

"Then let's have the designs. How does your ship beat the Zeppelin? What's she made of? Tell me everything; remember I'm ignorant. I just know that an aeroplane is a heavier-than-air machine, and a Zepplin's a lighter-than-air; that is, once she's inflated with gas. Fire away. I'm dying to get in at the actual building."

Joe was a practical young fellow, and was not to be hastened. He unlocked a leather bag lying near his feet and abstracted a sheet of glistening paper. Spreading it out on the table, he showed his uncle a big detail drawing of the machine he proposed to construct.

"It's not easy to follow the outline here," he said. "Wait till the ship's finished. But you can see this much. She's long and pointed at either end, and looks like a flattened cigar. That's how she differs from the Zeppelins. She's built very flat, and extends on either side till the top and bottom half come together in what may be called a lateral keel."

"Why? Where's the reason?"

"To protect her against gusts of wind and gales. A Zeppelin can't escape. Every breath plays on her big lateral bulk. In my ship the wind strikes a thin keel on whichever side it comes, is divided there, and passes over and under the ship, sliding as it were upwards and downwards away from the gradually-sloping surfaces which lead from those keels. In fact, the ship is almost as flat as a tortoise, and as wide comparatively, though she's very much longer."

"And—and this flattening of the ship makes her laugh at gales?" asked Andrew, staring at the plans before him.
