The clocks of London were all striking the single stroke of midnight as the two priests stood on the wind-sheltered platform of the volor, waiting for the start.
To Monsignor Masterman the scene was simply overwhelming. There was hardly a detail that was not new and unfamiliar. From where he stood on the upper deck, grasping the rail before him, his eyes looked out over a luminous city as lovely as fairyland. There were no chimneys, of course (these, he had just learnt, had altogether disappeared more than fifty years ago), but spires and towers and pinnacles rose before him like a dream, glowing against the dark sky, lit by the soft radiance of the streets beneath. To the right, not a hundred yards away, rose Saint Edward's tower, mellowed now to clear orange by the lapse of three-quarters of a century; to the left a flight of buildings, of an architectural design which he did not understand, but which gave him a sense of extreme satisfaction; in front towered the masses of Buckingham Palace as he seemed always to have known it.
The platform of the flying ship on which he stood hung in dock at least three hundred feet high above the roads beneath. He had examined the whole vessel just now from stem to stern, and had found it vaguely familiar; he determined to examine it again presently. There was no gas-bag to sustain it—so much he had noticed—though he could not say whence he had the idea that gas-bags were usual. But it seemed to him as if the notion of airships did carry some faint association to his mind, although far less distinct than that of motor-cars and even trains. He had enquired of his companion an hour or two earlier as they had discussed their journey as to whether they would not go by train and steamer, and had received the answer that these were never used except for very short journeys.
Here, then, he stood and stared.
It was very quiet up here; but he listened with considerable curiosity to the strange humming sound that filled the air, rising and falling, as of a beehive. At first he thought it was the working of engines in the ship; but he presently perceived it to be the noise of the streets rising from below; and it was then that he saw for the first time that foot-passengers were almost entirely absent, and that practically the whole roadway, so far as he could make out from the high elevation at which he stood, was occupied by cars of all descriptions going this way and that. They sounded soft horns as they went, but they bore no lights, for the streets were as light as day with a radiance that seemed to fall from beneath the eaves of all the buildings that lined them. This effect of lighting had a curious result of making the city look as if it were seen through glass or water—a beautifully finished, clean picture, moving within itself like some precise and elaborate mechanism.
He turned round at a touch on his arm.
"You would like to see the start, perhaps," said the old priest. "We are a little late to-night. The country mails have only just arrived. But we shall be off directly now. Come this way."
The upper deck, as the two turned inwards, presented an extremely pleasant and reassuring picture. From stem to stern it ran clear, set out, however, with groups of tables and chairs clamped to the floor, at which sat a dozen parties or so, settling themselves down comfortably. There were no funnels, no bridge, no break at all to the delightful vista. The whole was lighted by the same device as were the streets, for round the upper edges of the transparent walls that held out the wind shone a steady, even glow from invisible lights.
In the very centre of the deck, however, was a low railing that protected the head of a staircase, and down this well the two looked.
"Shall I explain?" asked the old priest, smiling. "This is the latest model, you know. It has not been in use for more than a few months."
The other nodded.
"Tell me everything, please."
"Well, look right down there, below the second flight. The first flight leads to the second-class deck, and the flight below to the working parts of the ship. Now do you see that man's head, straight in the middle, in the bright light?—yes, immediately under. Well, that's the first engineer. He's in a glass compartment, you see, and can look down passages in every direction. The gas arrangements are all in front of him, and the——"
"Stop, please. What power is it that drives the ship? Is it lighter than air, or what?"
"Well, you see the entire framework of the ship is hollow. Every single thing you see—even the chairs and tables—they're all made of the metal aerolite (as it's generally called). It's almost as thin as paper, and it's far stronger than any steel. Now it's the framework of the ship that takes the place of the old balloon. It's infinitely safer, too, for it's divided by automatically closing stops into tens of thousands of compartments, so a leak here and there makes practically no difference. Well, when the ship's at rest, as it is now, there's simply air in all these tubes; but when it's going to start, there is forced into these tubes, from the magazine below, the most volatile gas that has been discovered——"
"What's it called?"
"I forget the real name. It's generally called aeroline. Well, this is forced in, until the specific gravity of the whole affair, passengers and all, is as nearly as possible the same as the specific gravity of the air."
"I see. Good Lord, how simple!"
"And the rest is done with planes and screws, driven by electricity. The tail of the boat is a recent development. (You'll see it when we're once started.) It's exactly like the tail of a bird, and contracts and expands in every direction. Then besides that there are two wings, one on each side, and these can be used, if necessary, in case the screws go wrong, as propellers. But usually they are simply for balancing and gliding. You see, barring collisions, there's hardly the possibility of an accident. If one set of things fails, there's always something else to take its place. At the very worst, we can but be blown about a bit."
"But it's exactly like a bird, then."
"Of course, Monsignor," said the priest, with twinkling eyes, "it isn't likely that we could improve upon Almighty God's design. We're very simple, you know. … Look, he's signalling. We're going to start. Come to the prow. We shall see better from there."
The upper deck ended in a railing, below which protruded, from the level of the lower deck, the prow proper of the boat. Upon this prow, in a small compartment of which the roof, as well as the walls, was of hardened glass, stood the steersman amid his wheels. But the wheels were unlike anything that the bewildered man who looked down had ever dreamed of. First, they were not more than six inches in diameter; and next, they were arranged, like notes on a keyboard, with their edges towards him, with the whole set curved round him in a semicircle.
"Those to right and left," explained the priest, "control the planes on either side; those in front, on the left, control the engines and the gas supply; and on the right, the tail of the boat. Watch him, and you'll see. We're just starting."
As he spoke three bells sounded from below, followed, after a pause, by a fourth. The steersman straightened himself as the first rang out and glanced round him; and upon the fourth, bent himself suddenly over the key board, like a musician addressing himself to a piano.
For the first instant Monsignor was conscious of a slight swaying motion, which resolved itself presently into a faint sensation of constriction on his temples, but no more. Then this passed, and as he glanced away again from the steersman, who was erect once more, his look happened to fall over the edge of the boat. He grasped his friend convulsively.
"Look," he said, "what's happened?"
"Yes, we're off," said the priest sedately.
Beneath them, on either side, there now stretched itself an almost illimitable and amazingly beautiful bird's-eye view of a lighted city, separated from them by what seemed an immeasurable gulf. From the enormous height up to which they had soared the city looked like a complicated flat map, of which the patches were dark and the dividing lines rivers of soft fire. This stretched practically to the horizon on all sides; the light toned down at the edges into a misty luminosity, but as the bewildered watcher stared in front of him, he saw how directly in their course there slid toward them two great patches of dark, divided
