There had been talk of mono-rails for several years. But the real mischief began when Brennan sprang his gyroscopic mono-rail car upon the Royal Society. It was the leading sensation of the 1907 soirees; that celebrated demonstration-room was all too small for its exhibition. Brave soldiers leading Zionists, deserving novelists, noble ladies, congested the narrow passage and thrust distinguished elbows into ribs the world would not willingly let break, deeming themselves fortunate if they could see "just a little bit of the rail." Inaudible, but convincing, the great inventor expounded his discovery, and sent his obedient little model of the trains of the future up gradients, round curves, and across a sagging wire. Itran along its single rail, on its single wheels, simple and sufficient; it stopped, reversed stood still, balancing perfectly. It maintained its astounding equilibrium amidst a thunder of applause. The audience dispersed at last, discussing how far they would enjoy crossing an abyss on a wire cable. "Suppose the gyroscope stopped!" Few of them anticipated a tithe of what the Brennan mono-rail would do for their railway securities and the face of the world.
In a few, years they realised better. In a little while no one thought anything of crossing an abyss on a wire, and the mono-rail was superseding the tram-lines, railways: and indeed every form of track for mechanical locomotion. Where land was cheap the rail ran along the ground, where it was dear the rail lifted up on iron standards and passed overhead; its swift, convenient cars went everywhere and did everything that had once been done along made tracks upon the ground.
When old Smallways died, Tom could think of nothing more striking to say of him than that, "When he was a boy, there wasn't nothing higher than your chimbleys--there wasn't a wire nor a cable in the sky!"Old SmallWays went to his grave under an intricate network of wires and cables, for Bun Hill became not only a sort of minor centre of power distribution--the Home Counties Power Distribution Company set up transformers and a generating station close beside the old gas-works--but, also a junction on the suburban mono-rail system. Moreover, every tradesman in the place, and indeed nearly every house, had its own telephone.
The mono-rail cable standard became a striking fact in urban landscape, for the most part stout iron erections rather like tapering trestles, and painted a bright bluish green. One, it happened, bestrode Tom's house, which looked still more retiring and apologetic beneath its immensity; and another giant stood just inside the corner of his garden, which was still not built upon and unchanged, except for a couple of advertisement boards, one recommending a two-and-sixpenny watch, and one a nerve restorer. These, by the bye, were placed almost horizontally to catch the eye of the passing mono-rail passengers above, and so served admirably to roof over a tool-shed and a mushroom-shed for Tom. All day and all night the fast cars from Brighton and Hastings went murmuring by overhead long, broad, comfortable-looking cars, that were brightly lit after dusk. As they flew by at night, transient flares of light and a rumbling sound of passage, they kept up a perpetual summer lightning and thunderstorm in the street below.
Presently the English Channel was bridged--a series of great iron Eiffel Tower pillars carrying mono-rail cables at a height of a hundred and fifty feet above the water, except near the middle, where they rose higher to allow the passage of the London and Antwerp shipping and the Hamburg-America liners.
Then heavy motor-cars began to run about on only a couple of wheels, one behind the other, which for some reason upset Tom dreadfully, and made him gloomy for days after the first one passed the shop...
All this gyroscopic and mono-rail development naturally absorbed a vast amount of public attention, and there,was also a huge excitement consequent upon the amazing gold discoveries off the coast of Anglesea made by a submarine prospector, Miss Patricia Giddy. She had taken her degree in geology and mineralogy in the University of London, and while working upon the auriferous rocks of North Wales, after a brief holiday spent in agitating for women's suffrage, she had been struck by the possibility of these reefs cropping up again under the water. She had set herself to verify this supposition by the use of the submarine crawler invented by Doctor Alberto Cassini. By a happy mingling of reasoning and intuition peculiar to her sex she found gold at her first descent, and emerged after three hours' submersion with about two hundredweight of ore containing gold in the unparalleled quantity of seventeen ounces to the ton. But the whole story of her submarine mining, intensely interesting as it is, must be told at some other time; suffice it now to remark simply that it was during the consequent great rise of prices, confidence, and enterprise that the revival of interest in flying occurred.
It is curious how that revival began. It was like the coming of a breeze on a quiet day; nothing started it, it came. People began to talk of flying with an air of never having for one moment dropped the subject. Pictures of flying and flying machines returned to the newspapers; articles and allusions increased and multiplied in the serious magazines. People asked in mono-rail trains, "When are we going to fly?" A new crop of inventors sprang up in a night or so like fungi. The Aero Club announced the project of a great Flying Exhibition in a large area of ground that the removal of slums in Whitechapel had rendered available.
The advancing wave soon produced a sympathetic ripple in the Bun Hill establishment. Grubb routed out his flying-machine model again, tried it in the yard behind the shop, got a kind of flight out of it, and broke seventeen panes of glass and nine flower-pots in the greenhouse that occupied the next yard but one.
