Instead of living permanently as a glorious nation, Israel died. If we should look into the history of the decline of Egypt, of Babylon, of Persia, of Greece, of Rome, we would find this same deadly law of heredity hastening their downfall. But what of America? Prof. Pearl of Johns Hopkins has pointed out that a population of about 200,000,000 could live within our national boundaries. It has been pointed out too that America will have that population within perhaps three generations, somewhere about the year 2,000. But where amidst all our questions, social, political and religious, can we find any more sobering question than this: What kind of blood will run in the veins of those swarming 200,000,000? Criminal, lunatic, alcoholic, or wise, industrious, intelligent, sober? What can we fathers, in this present generation, do to check these coming generations from sliding down into physical, mental and moral hell, to share the fate of many an empire and nation before our day that boasted of its permanent place in the heavens? To come to the point at once, if we are to save our coming generations from decay, we as a nation must waken up to several very solemn facts. The first fact is the power of blood, or, to speak more scientifically, the power of germ-plasm. Environment, however much we must praise its power, can only develope [sic] what powers the child has received before he was born. Heredity determines one's possibilities. Environment merely helps one reach those possibilities. My ancestors determined for me the size and shape of my skeleton, the vitality of my heart and lungs, the shape of my skull and brain, the color of my hair and eyes and a thousand other characteristics of my body. Out in Ohio, many years ago, the villagers used to watch my father racing and exclaim, "My! Watch Billie run." Thus my father gave me
