When Eadham discovered the substance, he probably thought of it as a mere cheap substitute for india rubber; it cost a few shillings a ton. But you can never tell all an invention will do. It was the genius of a man named Warming that pointed to the possibility of using it, not only for the tires of wheels, but as a road substance, and who organised the enormous network of public ways that speedily covered the world.
These public ways were made with longitudinal divisions. On the outer on either side went foot cyclists and conveyances travelling at a less speed than twenty-five miles an hour; in the middle, motors capable of speed up to a hundred; and the inner, Warming (in the face of enormous ridicule) reserved for vehicles travelling at speeds of a hundred miles an hour and upward.
For ten years his inner ways were vacant. Before he died they were the most crowded of all, and vast light frameworks with wheels of twenty and thirty feet in diameter, hurled along them at paces that year after year rose steadily towards two hundred miles an hour. And by the time this revolution was accomplished, a parallel revolution had transformed the ever-growing cities. Before the development of practical science the fogs and filth of Victorian times vanished. Electric heating replaced fires (in 2013 the lighting of a fire that did not absolutely consume its own smoke was made an indictable nuisance), and all the city ways, all public squares and places, were covered in with a recently invented glass-like substance. The roofing of London became practically continuous. Certain short-sighted and foolish legislation against tall buildings was abolished, and London, from a squat expanse of petty houses—feebly archaic in design—rose steadily towards the sky. To the municipal responsibility for water, light, and drainage, was added another, and that was ventilation.
But to tell of all the changes in human convenience that these two hundred years brought about, to tell of the long foreseen invention of flying, to describe how life in households was steadily supplanted by life in interminable hotels, how at last even those who were still concerned in agricultural work came to live in the towns and to go to and fro to their work every day, to describe how at last in all England only four towns remained, each with many millions of people, and how there were left no inhabited houses in all the countryside: to tell all this would take us far from our story of Denton and his Elizabeth. They had been separated and reunited, and still they could not marry. For Denton—it was his only fault—had no money. Neither had Elizabeth until she was twenty-one, and as yet she was only eighteen. At twenty-one all the property of her mother would come to her, for that was the custom of the time. She did not know that it was possible to anticipate her fortune, and Denton was far too delicate a lover to suggest such a thing. So things stuck hopelessly between them. Elizabeth said that she was very unhappy, and that nobody understood her but Denton, and that when she was away from him she was wretched; and Denton said that his heart longed for her day and night. And they met as often as they could to enjoy the discussion of their sorrows.
They met one day at their little seat upon the flying stage. The precise site of this meeting was where in Victorian times the road from Wimbledon came out upon the common. They were, however, five hundred feet above that point. Their seat looked far over London. To convey the appearance of it all to a nineteenth-century reader would have been difficult. One would have had to tell him to think of the Crystal Palace, of the newly built "mammoth" hotels—as those little affairs were called—of the larger railway stations of his time, and to imagine such buildings enlarged to vast proportions and run together and continuous over the whole metropolitan area. If then he was told that this continuous roof-space bore a huge forest of rotating wind-wheels, he would have begun very dimly to appreciate what to these young people was the commonest sight in their lives.
To their eyes it had something of the quality of a prison, and they were talking, as they had talked a hundred times before, of how they might escape from it and be at last happy together: escape from it, that is, before the appointed three years were at an end. It was, they both agreed, not only impossible but almost wicked, to wait three years. "Before that," said Denton—and the notes of his voice told of a splendid chest—"we might both be dead!"
Their vigorous young hands had to grip at this, and then Elizabeth had a still more poignant thought that brought the tears from her wholesome eyes and down her healthy cheeks. "One of us," she said, "one of us might be—"
She choked; she could not say the word that is so terrible to the young and happy.
Yet to marry and be very poor in the cities of that time was—for any one who had lived pleasantly—a very dreadful thing. In the old agricultural days that had drawn to an end in the eighteenth century there had been a pretty proverb of love in a cottage; and indeed in those days the poor of the countryside had dwelt in flower-covered, diamond-windowed cottages of thatch and plaster, with the sweet air and earth about them, amidst tangled hedges and the song of birds, and with the ever-changing sky overhead. But all this had changed (the change was already beginning in the nineteenth century), and a new sort of life was opening for the poor—in the lower quarters of the city.
In the nineteenth century the lower quarters were still beneath the sky; they were areas of land on clay or other unsuitable soil, liable to floods or exposed to the smoke of more fortunate districts, insufficiently supplied with water, and as insanitary as the great fear of infectious diseases felt by the wealthier classes permitted. In the twenty-second century, however, the growth of the city storey above storey, and the coalescence of buildings, had led to a different arrangement. The prosperous people lived in a vast series of sumptuous hotels in the upper storeys and halls of the city fabric; the industrial population dwelt beneath in the tremendous ground-floor and basement, so to speak, of the place.
