The land, the water, and the fertilizer being thus assured, they would find the climate such that even the intensive methods of gardening now customary in Japan, would give no idea of the possibilities of acreage production in the Colorado River Valley. In that valley acreculture would be hothouse culture out-of-doors. The hot climate of the country would be found, when this economic survey of it was made, to be its greatest asset. They would find that every product of the tropical and semi-tropical countries of the world could be here produced to perfection. They would find that by actual experience extending over many years, an acre of land in such a climate, closely cultivated and abundantly fertilized, and cropped several times a year, would produce from $1000 to $2000 net profit annually and even more, depending on the skill of the cultivator. They would find that the skilled soil-cultivators of Japan could by this system of hothouse culture out-of-doors, provide all the food for an average family for a year, and produce over and above that an average of $1000 net profit per acre every year. This would include every product now successfully grown in Southern California. They would find that the Colorado River could be canalized from Yuma to the Needles, and the Gila and Salt Rivers canalized from Yuma to Phoenix and Florence, and a ship canal built from Yuma to the Gulf of California. Then the products from this wonderfully prolific country could be shipped from Yuma to every seaport of the world. Through the Panama Canal they could reach every seaport on the Atlantic Coast. By trans-shipment at New Orleans to canal or river steamers or barges they would connect with a river system 20,000 miles in extent for the distribution of their products to inland territory. They would calculate the cost of reclamation and the value of the reclaimed land, measured by its productive power. They would figure that they could afford to spend on the reclamation of the land at least an amount equal to the value of one year's production from the land. That would be $1000 per acre. Figuring only on the 5,000,000 acres that could be reclaimed in the main lower valley of the Colorado River below the canyon, they would find that it would justify a total expenditure of five billion dollars. Some enterprising American Congressional Economist would then tell them that they surely could not contemplate spending that much _on anything but a war_. They would tell him that they were _going into a war with the Desert_ and they proposed to triumph in it, just as they triumphed in the war with Russia. There would be this difference: all they spent on the Russian War was gone past recovery. They had to spend it or cease to exist as a nation. In this war with the Desert they would spend five billion dollars, and for it they would create a country that would produce food worth five billion dollars a year every year through all future time.
