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. "Then we ascend. What's the time?" asked Joe. "Eight thirty, sir," answered Dick promptly. "Eight thirty p.m." "Precisely; and the day is Wednesday?" "Yes, sir." "Then in one hundred and twenty-four days, less three hours and thirty minutes from this moment, we are due to return. If we are here then, and our foreign office passport has been properly initialled, then we shall have won the challenge. We can let her go. Stand by there! I'm going to take her up quickly. Then London shall have a glimpse of their ship, and afterwards----" "Yes, afterwards?" asked Commander Jackson, who had now joined them. Joe shrugged his shoulders. "Who can say? I myself have confidence in the vessel. But accidents may happen. We might be delayed by the smallest and most unexpected circumstance. We can but make the attempt." "And win or lose I shall be satisfied," chimed in Andrew. "Let her go."
