There are many other lines of our internal development that are yet barely begun. Irrigation is an example of this. The report of John W. Noble, Secretary of the Interior for 1891, said, "One hundred and twenty million acres that are now desert may be redeemed by irrigation so as to produce the cereals, fruits, and garden products possible in the climate where the lands are located." That is an area nearly twice as large as the Philippine Islands, and it is open to the American settler, while there is an indication that the Philippines may be inaccessible on account of their climate. Moreover, they are four times as densely populated as is the United States; and while we deem the Chinese so undesirable that we exclude him from our shores, all authorities agree that his race is superior to that of the Malays, Tagals, and Negritos who inhabit the Philippines. The irrigable area is much larger than the States of New York, Pennsylvania, Illinois, and Massachusetts combined. Those States at the present time are supporting a population of over seventeen millions, and many authorities claim that they will in the future support at least fifty millions. The regions of scanty rainfall that can be irrigated are fairly crusted with potash and other soluble mineral ingredients that nourish plant life, and give to the valleys already irrigated their astonishing fertility. This enables the farmers to support themselves on such small areas that the life is almost a communal one. The irrigated West can sustain a population as great as that sustained on an equal area in the East, or even greater.[F] For years that dry climate has been a health restorer to the sojourner there. This is not claimed for the Philippine Islands. The building up of this Western empire with its canals and irrigating ditches, its railroads and cities, will absorb a vast amount of capital, and it is a natural and easy line of development for us. Mr. Irwin has said, "To capital seeking investment in a large way, irrigation enterprises in the West offer a most solid, lucrative, and tempting field."[G] Secretary Noble has said, "No one can now compute the money value that will concentrate in these reservoirs and canals and ditches, carrying water to the fields of the husbandman, and upon which the people must depend for their prosperity."[H] [Footnote F: If we accept the reclaimable area given above as approximately correct, and apply a system of irrigation, it can be cultivated, "and made the happy home of an industrious people more than equaling in number the inhabitants of the United Kingdom of Great Britain and Ireland."--_J. N. Irwin, in Forum, vol. i, p. 742._] [Footnote G: Forum, vol. xii, p. 750.] [Footnote H: Report of the Secretary of the Interior, 1891.] Five centuries ago large parts of eastern and western England were impenetrable morasses. These have entirely disappeared before the skill of the engineer.
