The work progressed upon the Orion, and the sound of hammers was heard all the day. A long silken pipe had been connected to the gas bag, and terminated near a small, bell-shaped aluminum receiver. The poles of the storage batteries had been joined to a dozen pairs of carbon points within this receiver, and a series of long pipes projected from its base. Two huge safety-valves had been placed in the top of the great gas bag, and additional escape provided. It was 9 dial of the 12th of January, and great crowds of people filled the streets, covered the house-tops, and jammed themselves into every available place from which a view could be had of the departure of the Orion. At the dock of the vessel the President, Secretaries, foreign ministers, and other notables were assembled to witness the departure of the man who had promised to reach the pole and return.

The huge silken bag still lay inert and motionless against the aluminum support, no attempt having been made to fill it. The baggage had been placed on board; the stores, the meteorite, and nitric acid were carefully in place, and the crew, consisting of two pilots, a cook, cabin boy, and two engineers, were standing near the vessel.

A moment later Junius Cobb appeared, and by his side walked Craft and Hathaway. Their appearance was greeted by cheer upon cheer from the vast concourse of people. Slowly approaching the big ship, they mounted the ladders to the side, and stood upon the deck of the Orion. Throwing off his coat, Cobb at once commenced his work. The meteorite was in sticks four feet long and an inch in diameter, and much resembled the sticks of lipthalite used on the Tracer. Taking a glass cylinder five feet in length by one in diameter, he filled it nearly full of nitric acid, and then placed a bunch of the meteorite rods in the liquid. Waiting but a moment, he withdrew them, and then put one into each of the ten pipes of the receiver, placed springs against their ends, and closed the caps. Having thus charged the receiver, he stepped back, and touched a push-button, and turned on the current to the carbons inside.

Slowly at first, then faster, rose fold upon fold of the gas bag of the Orion; the gas was generating. The crowd cheered. For two hours the process was continued, until the Orion just balanced at her moorings; then and only then, Cobb ceased to fill the receiver. The 2,500 pounds of meteorite and fifty gallons of nitric acid, which had been brought as an extra supply, had been nearly all consumed, and over 1,500,000 cubic feet of meteorlene filled the great gas bag to within one-seventh of its capacity.

Stepping down the ladders, Cobb and his two companions bade good-bye to their friends. The crew went aboard, and then the three officers followed. At 11:57 the receiver pipes were again charged, and the electric current turned on; the great ship tugged hard at her cables, and swayed in the air.

“Cast off!” thundered the words from Cobb, and the hawsers whirled through the guards, and came tumbling to the ground. The vessel rose swiftly and gracefully in the air; the dial marked 12.

High up in the cold winter air, and swiftly, the noble ship rose; and soon the tooting of whistles and the cheers of the people became but faint murmurings in the depths below.

“Admiral,” reported Hugh, making a grave salute, and with a twinkle in his eye, “the barometer shows 8,000 feet.”

The fact was apparent that a great elevation had already been attained, for the temperature had fallen and a decided cold feeling was experienced by all.
