Manifestations reach to different roots. Algernon was checked off before he was born by way of a sexually-perverted instinct, or in an extraordinary mating hunger that marks him for bestial business, unless he is most carefully brought-up. Bernard harks back to a line of moral crooks, kept out of jail by legal see-saw. "Butch the Bull," scion of a father who made a living spilling the blood of his kind, and of a mother who was proud of the father, takes as naturally to heartless thuggery and its more pernicious by-products, as does a buck to butting. Each tells that blood tells, in that his selection of criminous groove will be governed largely by his instinctive predilections. Criminal man is usually but an enlarged portrait of the boy playmate. Hence, your natural sexual, thief, or thug, will inevitably begin to so unfold at a game of marbles. At a given moment, sentient man is the sum of the manner in which he had fought known congenital predisposition to express unsocial conduct, and the total of objective influence exerted upon him. For that which he lacks in character on a certain day, date and year, much betimes may be discounted as the quite natural result of cumulative circumstance, all of it spiteful; but that fact does not alter the basic truth stated. And so, since America went out of her way to ransack the discard of nations for her prospective citizens; and since criminals and potential criminals of each national group bore with them to America that by which they were peculiarly motivated to criminality in their native lands; and since America has been out-breeding from such stock for over two centuries; and since America sneezes at leaping license as no other nation sneezes at license: it follows perforce that the psychology of the average American criminal will be singularly complex. Atavism kneels neither to brain nor brawn. It will not be denied; not even the Mendelian law holds it wholly safe. Deviations that defy analysis will crop out. The crack in character apparently closes and merges, then opens wide after the lapse certainly of six generations, probably from way back of any genealogical tree yet branched by human brains.
