For a while, as Graham went through the passages of the Wind-Vane offices with Lincoln, he was preoccupied. But, by an effort, he attended to the things which Lincoln was saying. Soon his preoccupation vanished. Lincoln was talking of flying. Graham had a strong desire to know more of this new human attainment. He began to ply Lincoln with questions. He had followed the crude beginnings of aerial navigation very keenly in his previous life; he was delighted to find the familiar names of Maxim and Pilcher, Langley and Chanute, and, above all, of the aerial proto-martyr Lillienthal, still honoured by men.
Even during his previous life two lines of investigation had pointed clearly to two distinct types of contrivance as possible, and both of these had been realised. On the one hand was the great engine-driven aeroplane, a double row of horizontal floats with a big aerial screw behind, and on the other the nimbler aeropile. The aeroplanes flew safely only in a calm or moderate wind, and sudden storms, occurrences that were now accurately predictable, rendered them for all practical purposes useless. They were built of enormous size--the usual stretch of wing being six hundred feet or more, and the length of the fabric a thousand feet. They were for passenger traffic alone. The lightly swung car they carried was from a hundred to a hundred and fifty feet in length. It Was hung in a peculiar manner in order to minimise the complex vibration that even a moderate wind produced, and for the same reason the little seats within the car--each passenger remained seated during the voyage--were slung with great freedom of movement. The starting of the mechanism was only possible from a gigantic car on the rail of a specially constructed stage. Graham had seen these vast stages, the flying stages, from the crow's nest very well. Six huge blank areas they were, with a giant "carrier" stage on each.
The choice of descent was equally circumscribed, an accurately plane surface being needed for safe grounding. Apart from the destruction that would have been caused by the descent of this great expanse of sail and metal, and the impossibility of its rising again, the concussion of an irregular surface, a tree-set hillside, for instance, or an embankment, would be sufficient to pierce or damage the framework, to smash the ribs of the body, and perhaps kill those aboard.
At first Graham felt disappointed with these cumbersome contrivances, but he speedily grasped the fact that smaller machines would have been unremunerative, for the simple reason that their carrying power would be disproportionately diminished with diminished size. Moreover, the huge size of these things enabled them--and it was a consideration of primary importance--to traverse the air at enormous speeds, and so run no risks of unanticipated weather. The briefest journey performed, that from London to Paris, took about three-quarters of an hour, but the velocity attained was not high; the leap to New York occupied about two hours, and by timing oneself carefully at the intermediate stations it was possible in quiet weather to go around the world in a day.
The little aeropiles (as for no particular reason they were distinctively called) were of an altogether different type. Several of these were going to and fro in the air. They were designed to carry only one or two persons, and their manufacture and maintenance was so costly as to render them the monopoly of the richer sort of people. Their sails, which were brilliantly coloured, consisted only of two pairs of lateral air floats in the same plane, and of a screw behind. Their small size rendered a descent in any open space neither difficult nor disagreeable, and it was possible to attach pneumatic wheels or even the ordinary motors for terrestrial tragic to them, and so carry them to a convenient starting place. They required a special sort of swift car to throw them into the air, but such a car was efficient in any open place clear of high buildings or trees. Human aeronautics, Graham perceived, were evidently still a long way behind the instinctive gift of the albatross or the fly-catcher. One great influence that might have brought the aeropile to a more rapid perfection had been withheld; these inventions had never been used in warfare. The last great international struggle had occurred before the usurpation of the Council.
The Flying Stages of London were collected together in an irregular crescent on the southern side of the river. They formed three groups of two each and retained the names of ancient suburban hills or villages. They were named in order, Roehampton, Wimbledon Park, Streatham, Norwood, Blackheath, and Shooter's Hill. They were uniform structures rising high above the general roof surfaces. Each was about four thousand yards long and a thousand broad, and constructed of the compound of aluminium and iron that had replaced iron in architecture. Their higher tiers formed an openwork of girders through which lifts and staircases ascended. The upper surface was a uniform expanse, with portions--the starting carriers--that could be raised and were then able to run on very slightly inclined rails to the end of the fabric. Save for any aeropiles or aeroplanes that were in port these open surfaces were kept clear for arrivals.
During the adjustment of the aeroplanes it was the custom for passengers to wait in the system of theatres, restaurants, news-rooms, and places of pleasure and indulgence of various sorts that interwove with the prosperous shops below. This portion of London was in consequence commonly the gayest of all its districts, with something of the meretricious gaiety of a seaport or city of hotels. And for those who took a more serious view of aeronautics, the religious quarters had flung out an attractive colony of devotional chapels, while a host of brilliant medical establishments competed to supply physical preparatives for the journey. At various levels through the mass of chambers and passages beneath these, ran, in addition to the main moving ways of the city which laced and gathered here, a complex system of special passages and lifts and slides, for the convenient interchange of people and luggage between stage and stage. And a distinctive feature of the architecture of this section was the ostentatious massiveness of the metal piers and girders that everywhere broke the vistas and spanned the halls and passages, crowding and twining up to meet the weight of the stages and the weighty impact of the aeroplanes overhead.
Graham went to the flying stages by the public ways. He was accompanied by Asano, his Japanese attendant. Lincoln was called away by Ostrog, who was busy with his administrative concerns. A strong guard of the Wind-Vane police awaited the Master outside the Wind-Vane offices, and they cleared a space for him on the upper moving platform. His passage to the flying stages was unexpected, nevertheless a considerable crowd gathered and followed him to his destination. As he went along, he could hear the people shouting his name, and saw numberless men and women and children in blue come swarming up the staircases in the central path, gesticulating and shouting. He could not hear what they shouted. He was struck again by the evident existence of a vulgar dialect among the poor of the city. When at last he descended, his guards were immediately surrounded by a dense excited crowd. Afterwards it occurred to him that some had attempted to reach him with petitions. His guards cleared a passage for him with difficulty.
He found an aeropile in charge of an aeronaut awaiting him on the westward stage. Seen close this mechanism was no longer small. As it lay on its launching carrier upon the wide expanse of the flying stage, its aluminium body skeleton was as big as the hull of a twenty-ton yacht. Its lateral supporting sails braced and stayed with metal nerves almost like the nerves of a bee's wing, and made of some sort of glassy artificial membrane, cast their shadow over many hundreds of square yards. The chairs for the engineer and his passenger hung free to swing by a complex tackle, within the protecting ribs of the frame and well abaft the middle. The passenger's chair was protected by a wind-guard and guarded about with metallic rods carrying air cushions. It could, if desired, be completely closed in, but Graham was anxious for novel experiences, and desired that it should be left open. The aeronaut sat behind a glass that sheltered his face. The passenger could secure himself firmly in his seat, and this was almost unavoidable on landing, or he could move along by means of a little rail and rod to a locker at the stem of the machine, where his personal luggage, his wraps and restoratives were placed, and which also with the seats, served as a makeweight to the parts of the central engine that projected to the propeller at the stern.
The engine was very simple in appearance. Asano, pointing out the parts of this apparatus to him, told him that, like the gas-engine of Victorian days, it was of the explosive type, burning a small drop of a substance called "fomile" at each stroke. It consisted simply of reservoir and piston about the long fluted crank of the propeller shaft. So much Graham saw of the machine.
The flying stage about him was empty save for Asano and their suite of attendants. Directed by the aeronaut he placed himself in his seat. He then drank a mixture containing ergot--a dose, he learnt, invariably administered to those about to fly, and designed to counteract the possible effect of diminished air pressure upon the system. Having done so, he declared himself ready for the journey. Asano took the empty glass from him, stepped through the bars of the hull, and stood below on the stage waving his hand. Suddenly he seemed to slide along the stage to the right and vanish.
The engine was beating, the propeller spinning, and for a second the stage and the buildings beyond were gliding swiftly and horizontally past Graham's eye; then these things seemed to tilt up abruptly. He gripped the little rods on either side of him instinctively. He felt himself moving upward, heard the air whistle over the top of the wind screen. The propeller screw moved round with powerful rhythmic impulses--one, two, three, pause; one, two, three--which the engineer controlled very delicately. The machine began a quivering vibration that continued throughout the flight, and the roof areas seemed running away to starboard very quickly and growing rapidly smaller. He looked from the face of the engineer through the ribs of the machine. Looking sideways, there was nothing very startling in what he saw--a rapid funicular railway might have given the same sensations. He recognised the Council House and the Highgate Ridge. And then he looked straight down between his feet.
For a moment physical terror possessed him, a passionate sense of insecurity. He held tight. For a second or so he could not lift his eyes. Some hundred feet or more sheer below him was one of the big windvanes of south-west London, and beyond it the southernmost flying stage crowded with little black dots. These things seemed to be falling away from him. For a second he had an impulse to pursue the earth. He set his teeth, he lifted his eyes by a muscular effort, and the moment of panic passed.
He remained for a space with his teeth set hard, his eyes staring into the sky. Throb, throb, throb--beat, went the engine; throb, throb, throb,--beat. He gripped his bars tightly, glanced at the aeronaut, and saw a smile upon his sun-tanned face. He smiled in return--perhaps a little artificially. "A little strange at first," he shouted before he recalled his dignity. But he dared not look down again for some time. He stared over the aeronaut's head to where a rim of vague blue horizon crept up the sky. For a little while he could' not banish the thought of possible accidents from his mind. Throb, throb, throb--beat; suppose some trivial screw went wrong in that supporting engine! Suppose--! He made a grim effort to dismiss all such suppositions. After a while they did at least abandon the foreground of his thoughts. And up he went steadily, higher and higher into the clear air.
Once the mental shock of moving unsupported through the air was over, his sensations ceased to be unpleasant, became very speedily pleasurable. He had been warned of air sickness. But he found the pulsating movement of the aeropile as it drove up the faint south-west breeze was very little in excess of the pitching of a boat head on to broad rollers in a moderate gale, and he was constitutionally a good sailor. And the keenness of the more rarefied air into which they ascended produced a sense of lightness and exhilaration. He looked up and saw the blue sky above fretted with cirrus clouds. His eye came cautiously down through the ribs and bars to a shining flight of white birds that hung in the lower sky. For a space he watched these. Then going lower and less apprehensively, he saw the slender figure of the Wind-Vane keeper's crow's nest shining golden in the sunlight and growing smaller every moment. As his eye fell with more confidence now, there came a blue line of hills, and then London, already to leeward, an intricate space of roofing. Its near edge came sharp and clear, and banished his last apprehensions in a shock of surprise. For the boundary of London was like a wall, like a cliff, a steep fall of three or four hundred feet, a frontage broken only by terraces here and there, a complex decorative facade.
That gradual passage of town into country through an extensive sponge of suburbs, which was so characteristic a feature of the great cities of the nineteenth century, existed no longer. Nothing remained of it but a waste of ruins here, variegated and dense with thickets of the heterogeneous growths that had once adorned the gardens of the belt, interspersed among levelled brown patches of sown ground, and verdant stre............
