The native Americans are splendid raw material, but have as yet only an imperfectly developed national consciousness. They lack the instinct of self-preservation in a racial sense. Unless such an instinct develops their race will perish, as do all organisms which disregard this primary law of nature. Nature had granted to the Americans of a century ago the greatest opportunity in recorded history to produce in the isolation of a continent a powerful and racially homogeneous people and had provided for the experiment a pure race of one of the most gifted and vigorous stocks on earth, a stock free from the diseases, physical and moral, which have again and again sapped the vigor of the older lands. Our grandfathers threw away this opportunity in the blissful ignorance of national childhood and inexperience. The result of unlimited immigration is showing plainly in the rapid decline in the birth rate of native Americans because the poorer classes of Colonial stock, where they still exist, will not bring children into the world to compete in the labor market with the Slovak, the Italian, the Syrian and the Jew. The native American is too proud to mix socially with them and is gradually withdrawing from the scene, abandoning to these aliens the land which he conquered and developed. The man of the old stock is being crowded out of many country districts by these foreigners just as he is to-day being literally driven off the streets of New York City by the swarms of Polish Jews. These immigrants adopt the language of the native American, they wear his clothes, they steal his name and they are beginning to take his women, but they seldom adopt his religion or understand his ideals and while he is being elbowed out of his own home the American looks calmly abroad and urges on others the suicidal ethics which are exterminating his own race. When the test of actual battle comes, it will, of course, be the native American who will do the fighting and suffer the losses. With him will stand the immigrants of Nordic blood, but there will be numbers of these foreigners in the large cities who will prove to be physically unfit for military duty. As to what the future mixture will be it is evident that in large sections of the country the native American will entirely disappear. He will not intermarry with inferior races and he cannot compete in the sweat shop and in the street trench with the newcomers. Large cities from the days of Rome, Alexandria, and Byzantium have always been gathering points of diverse races, but New York is becoming a _cloaca gentium_ which will produce many amazing racial hybrids and some ethnic horrors that will be beyond the powers of future anthropologists to unravel.
