Frenchmen frothed to indiscriminate murder in reprisals that miscarried; which is to say: their revolutions left millions of the sons and daughters of France with a grossly exaggerated idea of the importance of the individual in the mass, now expressed periodically in mercurial uprisings engineered in the main by the progeny of those who hung on Madam Defarge's heartless words, and watched with glee the fall of guillotined heads. Americans built to liberty as liberty never before had been framed and nailed: then they bade anti-social vandals come on over and raze the structure with tools fashioned for all forms of license. They came, they used the tools, they are using them, and they will get the job done unless Americans come out of it and postpone their social siesta. By and large, the bulk of America's criminals are the natural offspring of the natural foes of freedom as the forefathers sensed freedom. Instinct is far more tenacious than anything with which it may be challenged; hence it is that a bulging minority of the polyglot of the mass on continental American soil seethe, and plan, and execute, even kill, to the end that they may establish a social order diametrically opposed to constitutional diction. What is more, openly-avowed efforts to change the national course are the least fateful. Basic danger resides in the insidious undertow: in that which is given no voice, yet which is wormed patiently, indefatigably, to the foundations of American institutions. Therefore, when you have an American-bred criminal, you usually have one, as it were, out of Pandora's box; one to whose ancestry and whose natural instincts and predilections because of that ancestry, and to whose bringing-up you needs must possess the master-key, else betimes surely miss underlying motives. Unquestionable observation and experiment declare for this guiding principle: in out-breeding of humans, good traits of character, from either side, may, or may not, issue; whereas bad instincts nearly always carry in emphasis from both sides. Hence, a country that recruits its citizenship from the four corners of earth, must, if it is to endure and persist for human progress, select of foreign-born units strictly on the basis of quality. Never mind either calculus or the alphabet; encourage God-fearing, law-abiding, hard-working young men and women who want to root in American soil, to do so. Then bar every individual who cannot present clean bills of health and social character. Bar him, essentially, her, at the port of egress. Fundamentally, the immigration question is no more complex, in so far as the only rational course for the United States to pursue is concerned, than is breeding of prize cattle; it is this: eliminate all but good-mannered producers who transmit reliably to the best qualities of their breed.
