But this flood ended as suddenly as it had begun. When the age-long accumulations of snow had all melted the torrents ceased to pour down from the mountains, and immediately the courageous and industrious inhabitants of the Netherlands began to repair their broken dikes, while in Northern Italy and the plains of Southeastern France every effort was made to repair the terrible losses. Of course similar scenes had been enacted, and on even a more fearful scale, in the plains of India, flooded by the melting of the enormous icy burden that covered the Himalayas, the "Abode of Snow." And all over the world, wherever icy mountains reared themselves above inhabited lands, the same story of destruction and death was told. Then, after an interval, came the yet more awful invasion of the sea. But few details can be given from lack of records. The Thames roared backward on its course, and London and all central England were inundated. A great bore of sea-water swept along the shores of the English Channel, and bursting through the Skager Rack, covered the lower end of Sweden, and rushed up the Gulf of Finland, burying St. Petersburg, and turning all Western Russia, and the plains of Pomerania into a sea. The Netherlands disappeared. The Atlantic poured through the narrow pass of the Strait of Gibraltar, leaving only the Lion Rock visible above the waves. At length the ocean found its way into the Desert of Sahara, large areas of which had been reclaimed, and were inhabited by a considerable population of prosperous farmers. Nowhere did the sudden coming of the flood cause greater consternation than here--strange as that statement may seem. The people had an undefined idea that they were protected by a sort of barrier from any possible inundation. It had taken so many years and such endless labor to introduce into the Sahara sufficient water to transform its potentially rich soil into arable land that the thought of any sudden superabundance of that element was far from the minds of the industrious agriculturalists. They had heard of the inundations caused by the melting of the mountain snows elsewhere, but there were no snow-clad mountains near them to be feared. Accordingly, when a great wave of water came rushing upon them, surmounted, where it swept over yet unredeemed areas of the desert, by immense clouds of whirling dust, that darkened the air and recalled the old days of the simoom, they were taken completely by surprise. But as the water rose higher they tried valiantly to escape. They were progressive people, and many of them had aeros. Besides, two or three lines of aero expresses crossed their country. All who could do so immediately embarked in airships, some fleeing toward Europe, and others hovering about, gazing in despair at the spreading waters beneath them.
