Then the American Speculator would come on the scene with his accumulated wisdom gained through many failures of colonization schemes because there were no colonists or not enough to keep up with the interest on the bonds issued. The American Speculator would warn the Japanese against such a gigantic blunder as they were about to make in undertaking such a stupendous colonization scheme. And the Japanese Statesmen and Financiers would point out to him not only that they had all the colonists they needed right at home in Japan, but that instead of its being necessary to spend a large sum of money to induce those colonists to emigrate to the new lands, they were having much trouble now to keep the colonists from going to the Pacific Coast where they are not wanted. They would explain that they are overcrowded in Japan; that their surplus population must go somewhere; that they are the most skilled gardeners and orchardists in the world; that the same men who would build the irrigation works, and the power plants, would settle right down on the reclaimed lands, glad to get an acre apiece, and live on it and cultivate it with their families. So the Japanese in this thorough way would go at this great work of wresting a new Japanese Empire from the Desert. They would not do any construction work until they had made a complete comprehensive plan of every detail of this new empire they were starting to build. Then they would go to the Colorado Canyon and begin by building a great diversion dam as far down the canyon as might be practicable to lift the water high enough to carry it in high line canal systems along both sides of the valley, and to bring it out on the mesa lands and use it where the land most needs the silt for a fertilizer. They would figure on first reclaiming all the mesa land on which the water could in this way be used, and then they would build pumping plants with which to irrigate the more elevated lands. They would reclaim the mesa land first because every acre of mesa land that was reclaimed would serve as a sponge to soak up the flood water. By carrying out that plan they would eventually relieve the lowlands in the floor of the valley from all danger of overflow. They would not have to spend anything to control the floods of the Colorado River. There would be no floods. The Japanese would begin at the right end of the problem, and build big enough at the start to solve it as a whole, comprehensively. Their plan would be to use up every drop of the flood water by irrigating land with it. There would never at any time of the year be any water running to waste in the lower river. There would never be in the main river more than enough water to supply the canals that irrigated the lowlands of the lower delta. The ship canal from Yuma to the Gulf, and the canals from Yuma to the Needles, Phoenix, and Florence would be not irrigating canals, but drainage canals.
