De Croqueville squeezed back, and embraced Bobby on both cheeks. “My brave, my very dear, rely upon me. Madame”—he kissed the jeweled knuckles of Mrs. Gudrun—“all Paris is assembled to behold the most beautiful woman prove herself also to be of the most brave. M. le Duc,” he saluted De Petoburgh distantly, and then cordially shook hands, “I am as kin a sportsman as how you. I have plank my egg—my oof—a thousand francs you circulate the Tour Eiffel, in spite of the wind, which blows from the wrong quarter. Adieu!”

“Blows from the wrong quarter!” gasped Bobby Bolsover. The eyeglass of De Petoburgh turned in his direction, and he immediately climbed the forward ladder and got into the steersman’s creaking basket, and grasped the wheel with an awful sinking immediately below the heart.... The Duke helped Mrs. Gudrun to assume the central position, and got in astern. Just before the starting word was given and the great doors of the aërodrome rolled apart in their steel grooves, he leaned over to De Croqueville, addressing that gentleman in his own language:

“One supposes she”—he alluded to the vessel—“is—sea—I mean air-worthy—eh, my friend?”

De Croqueville shot up his eyebrows and spread his hands.

“One supposes.... Truly, dear friend, I know not!... The vessel is newly complete—this is what in English you call the try-trip. That is why I hedge my bet. One thousand francs you round the Tour Eiffel and return uninjure—two thousand you do not return uninjure—whether you round the Tour or no. Adieu-dieu!

The electric signal rang. The colossal doors groaned apart. The four workmen scuttled down the ladders like frightened mice, seized the guide-rope, and towed the airship out of dock. Paris waved handkerchiefs, cheered. Bobby Bolsover, ghastly behind his goggles, pressed the pedal and manipulated the wheel. The engine throbbed, the tail-shaft screw revolved. The adventurers had started.

“Qui-quite nice,” gulped Mrs. Gudrun tremulously, as the keen wind toyed with her silk veil and fluttered her fur boa.

“She pitches,” said De Petoburgh briefly. “Keep her head to it, Bolsover.”

There was a sickening moment as the airship mounted obliquely upward.... Then a tug at the guide-rope brought her nose down, pointing to the sea of fluttering handkerchiefs beneath. Mrs. Gudrun groaned and clung to the sides of her padded basket. De Petoburgh swore.

“I can’t—manage her. My—my nerve has gone. Let’s put about and take her back to dock again,” gasped Bobby.
