But to effect a discriminating change in the standards of the more intelligent and better educated classes calls for a real effort on the part of all those who have the welfare of society at heart. The difficulties are great enough and the obstacles are evident enough; it is more encouraging to look at the other side, and to see evidences that the public is awakening. The events of every month show that the ideals of eugenics are filtering through the public mind more rapidly than some of us, a decade ago, felt justified in expecting. There is a growing recognition of the danger of bad breeding; a growing recognition in some quarters at least of the need for more children from the superior part of the population; a growing outcry against the excessive standards of luxury that are making children themselves luxuries. The number of those who call themselves eugenists, or who are in sympathy with the aims of eugenics, is increasing every year, as is evidenced by the growth of such an organization as the American Genetic Association. Legislators show an eager desire to pass measures that as they (too often wrongly) believe will have a eugenic result. Most colleges and universities are teaching the principles of heredity, and a great many of them add definite instruction in the principles of eugenics. Although the ultimate aim of eugenics--to raise the level of the whole human race--is perhaps as great an undertaking as the human mind can conceive, the American nation shows distinct signs of a willingness to grapple with it. And this book will have failed in its purpose, if it has not convinced the reader that means are available for attacking the problem at many points, and that immediate progress is not a mere dream. One of the first necessary steps is a change in educational methods to give greater emphasis to parenthood. And this change, it is a great pleasure to be able to say, is being made in many places. The public schools are gradually beginning to teach mothercraft, under various guises, in many cities and the School of Practical Arts, Columbia Univ., gives a course in the "Physical Care of the Infant." Public and private institutions are beginning to recognize, what has long been ignored, that parenthood is one of the functions of men and women, toward which their education should be directed. Every such step will tend, we believe, to increase the birth-rate among the superior classes of the community; every such step is therefore, indirectly if not directly, a gain for eugenics; for, as we have emphasized time and again, a change in public opinion, to recognize parenthood as a beautiful and desirable thing, is one of the first desiderata of the eugenics program. The introduction of domestic science and its rapid spread are very gratifying, yet there are serious shortcomings, as rather too vigorously set forth by A. E. Hamilton:
