It is not a question as to whether the aliens will come. They have come, millions of them; they are now coming, at the rate of a million a year. They come from every clime, country, and condition; and they are of every sort: good, bad, and indifferent, literate and illiterate, virtuous and vicious, ambitious and aimless, strong and weak, skilled and unskilled, married and single, old and young, Christian and infidel, Jew and pagan. They form to-day the raw material of the American citizenship of to-morrow. What they will be and do then depends largely upon what our American Protestant Christianity does for them now.
