The remainder of their conversation was carried on in low tones and with the greatest earnestness. These two rascals, for both were that, bargained eagerly, and it was quite an hour later before they parted. Then Mr. Carl Reitberg passed out of the house, roughly pushed aside a poor woman who begged alms of him, hailed a taxi, and drove away to his gorgeous mansion. He left Adolf Fruhmann richer than he had been for many a day, with the promise of abundance in the future and sufficient money with which to carry on the plot so craftily hatched in that back room in the grimy house off Whitechapel. The following day found the magnate down at Joe Gresson's wonderful hangar again. He was geniality itself. He had come to wish the crew and the ship a safe voyage and a rapid one, and to hope that nothing might happen to arrest their progress or to damage the airship.

"To my old friend, Mr. Andrew Provost," he said, "and to his wonderful nephew, Mr. Joseph Gresson. May they return triumphant!"

Lifting the glass of wine he had been sipping and standing up he solemnly drank the health of the party. Then, with a cordial grip of the hand all round, he left the ship under the pilotage of Sergeant Evans. His tongue was in his cheek as he stepped on to the gangway which led to the floor of the hangar. He turned to wave his adieus to the people above, distinguishable through the framework of the vessel. And then he regarded the Sergeant with a puzzled expression.

"Strange," he said. "I seem to know your face, to have met you before."

"The other day, sir," came the respectful and guarded answer; "I took your card up to Mr. Andrew."

"Yes, that must be the explanation," Carl told himself, and departed satisfied. He was more than satisfied, in fact, and hugged himself in the depths of his motor car. For the interview had gone off wonderfully. A reporter who, thanks to his own skilful arrangement, had been present, proceeded at once to write up a glowing account of the meeting, and that evening the world learned that Mr. Carl Reitberg had been aboard the airship, where he had generously wished all the utmost success, had drank to their health, and had shown in every way that he was a sportsman. More than that, he had intimated his intention of at once depositing one hundred thousand pounds at his bankers', so that, in the likely event, as he hoped, of the successful termination of the venture, Mr. Andrew Provost might claim it instantly. What could be fairer or more magnanimous? What could be better calculated to throw dust in the eyes of the public, and, more important than all, in the eyes of the crew of the airship? Carl Reitberg not only hugged himself as he sank back amid the luxurious cushions of his landaulette. He chuckled loudly. He rubbed his fat hands unctuously together and positively grinned. Yes, he had been wonderfully canny and successful. It remained now for the crafty Adolf Fruhmann to carry on the conspiracy and see it to a successful ending.

"Bah! Thought he'd seen me before. Didn't let on that it was out in South Africa," Sergeant Evans was murmuring as he entered the vessel again. "Now if I know Mr. Reitberg he ain't up to any good. He's a foxy fellow at any time, the chap who sits at home and does the gentleman, while those friends of his carry out the scheme that he's after. Well, I for one will keep an eye open."

The three days which passed after Mr. Midshipman Hamshaw added his important presence to the airship were decidedly busy ones. He himself had his kit to obtain and friends to say farewell to. And then there was the victualling of the ship, a matter of great importance. All day and night carts arrived at the hangar, and the crew of the ship, composed almost entirely of soldiers and sailors, were engaged in piling cases upon the lift and hoisting them into the interior of the vessel. Sufficient tinned goods were taken to last the party for five months. There was fuel to be considered, and one had to remember that a journey of the description contemplated demanded various weights of clothing, weapons, ammunition, in fact a hundred and one items. But at length, thanks to Joe Gresson's foresight and Andrew Provost's energy, they were gathered and stored in the huge storage rooms of the vessel. The hangar swung round easily with her head away from the wind, while the motors began to rumble. Stationed with Joe in the engine-room Alec and Dick watched the young inventor gently handle a lever, and looking backward saw the gigantic propeller reverse. The ship moved. Those wide lateral keels running upon rollers inserted in the wide slots on either side, which were part and parcel of the hangar, began to slide gently away from their holding. The ship backed slowly and surely out of her hangar till she was entirely clear. A bell sounded in the engine-room, while a voice was heard through the loud-speaking telephone. It was from Hurst, now trained to new duties, and at that moment stationed on the upper deck, right on the prow of the vessel.

"All clear, sir," he called. "She backed forty feet from the hangar. All clear."

Another bell sounded. "All clear aft," came from Hawkins, stationed near the propeller.
