All this gives a clearer idea of the difficulties involved in a successful guarding of the gates. But it also confirms the conviction that the gates must be strictly guarded. If anything further were needed to reinforce that conviction it should be the present state of those white outposts where the gates have been left ajar. Hawaii is a good example. This mid-Pacific archipelago was brought under white control by masterful American Nordics, who established Anglo-Saxon institutions and taught the natives the rudiments of Anglo-Saxon civilization. The native Hawaiians, like the other Polynesian races, could not stand the pressure of white civilization, and withered away. But the white oligarchy which controlled the islands determined to turn their marvellous fertility to immediate profit. Labor was imported from the ends of the earth, the sole test being working ability without regard to race or color. There followed a great influx of Asiatic labor--at first Chinese until annexation to the United States brought Hawaii under our Chinese exclusion laws; later on Filipinos, Koreans, and, above all, Japanese. The results are highly instructive. These Asiatics arrived as agricultural laborers to work on the plantations. But they did not stay there. Saving their wages, they pushed vigorously into all the middle walks of life. The Hawaiian fisherman and the American artisan or shopkeeper were alike ousted by ruthless undercutting. To-day the American mechanic, the American storekeeper, the American farmer, even the American contractor, is a rare bird indeed, while Japanese corporations are buying up the finest plantations and growing the finest pineapples and sugar. Fully half the population of the islands is Japanese, while the Americans are being literally encysted as a small and dwindling aristocracy. In 1917 the births of the two races were: American, 295; Japanese, 5,000! Comment is superfluous. Clear round the globe, the island of Mauritius, the half-way house between Asia and Africa, tells the same tale. Originally settled by Europeans, mostly French, Mauritius imported negroes from Africa to work its rich soil. This at once made impossible the existence of a white laboring class, though the upper, middle, and artisan classes remained unaffected by the economically backward blacks. A hundred years ago one-third of the population were whites. But after the abolition of slavery the negroes quit work, and Asiatics were imported to take their place. The upshot was that the whites were presently swamped beneath the Asiatic tide--here mostly Hindus. To-day the Hindus alone form more than two-thirds of the whole population, the whites numbering less than one-tenth. Indeed, the very outward aspect of the island is changing. The old French landmarks are going, and the fabled land of "Paul and Virginia" is becoming a bit of Hindustan, with a Chinese fringe. Even Port Louis, the capital town, has mostly passed from white to Indian or Chinese hands.
