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 of little value to genetics, because of the inadequacy of the data they furnish. It is only in the case of exceptional families, such as the royal houses of Europe, that enough information is given about each individual to furnish an opportunity for analysis. What could be done if there were more such data available is brilliantly illustrated in the investigation by Frederick Adams Woods of Boston of the reigning houses of Europe. His writings should be read by every genealogist, as a source of inspiration as well as information. More such data must be obtained in the future. Genealogists must begin at once to keep family records in such a way that they will be of the greatest value possible--that they will serve not only family pride, but bigger purposes. It will not take long to get together a large number of family histories, in which the idea will be to tell as much as possible, instead of as little as possible, about every individual mentioned. The value of pedigrees of this kind is greater than most people realize.
