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. And then, springing from nowhere, sustained one knew not how, came a persistent, disturbing rumour that the problem had been solved, that the secret was known. Bert met it one early-closing afternoon as he refreshed himself in an inn near Nutfield, whither his motor-bicycle had brought him. There smoked and meditated a person in khaki, an engineer, who presently took an interest in Bert's machine. It was a sturdy piece of apparatus, and it had acquired a kind of documentary value in these quick-changing times; it was now nearly eight years old. Its points discussed, the soldier broke into a new topic with, “My next's going to be an aeroplane, so far as I can see. I've had enough of roads and ways.”
