a science, as long as it ignores eugenics. After all, nothing more is necessary than a slight change in the point of view; and if genealogists can adopt this new point of view, can add to their equipment some familiarity with the fundamental principles of biology as they apply to man and are laid down in the science of eugenics, the value of the science of genealogy to the world ought to increase at least five-fold within a generation.
What can be expected from a genealogy with eugenic foundation?
First and foremost, it will give genetics a chance to advance with more rapidity, in its study of man. Genetics, the study of heredity, can not successfully proceed by direct observation in the human species as it does with plants and rapidly-breeding animals, because the generations are too long. Less than three generations are of little value for genetic researches, and even three can rarely be observed to advantage by any one person. Therefore, second-hand information must be used. So far, most of this has been gained by sending field-workers—a new kind of genealogist—out among the members of a family, and having them collect the desired information, either by study of extant records, or by word of mouth. But the written records of value have been usually negligible in quantity, and oral communication has therefore been the mainstay. It has not been wholly satisfactory. Few people—aside from genealogists—can give even the names of all their great-grandparents, far less can they tell anything of importance about them.
It is thus to genealogy that genetics is driven. Unless family records are available, it can accomplish little. And it can not get these family records unless genealogists realize the importance of furnishing them; for as has already been pointed out, most genealogies at present available are
