The statistician, like the librarian, is also quick to create as well as to respond to the demand for information of a serious nature, and this has been shown in the growing recognition of the importance of domestic service as a field for statistical research. Among the most thorough of these statistical investigations is that carried on by Miss Isabel Eaton,--recently fellow of the College Settlements’ Association,--in regard to negro domestic service in the seventh ward of Philadelphia.[8] Miss Eaton has made an exhaustive study of one phase of the subject in a limited area, considering not only the number of negroes thus employed, but the methods of living, savings, and expenditures, amusements and recreations, length and quality of the service, conjugal condition, illiteracy, and health. The work has been done in a thoroughly scientific manner, and the results form an admirable presentation of negro service in a single ward of one city. Similar thorough investigations of special aspects of the question have been carried on by Miss Mary W. Dewson and Miss Edith G. Fabens for the Women’s Educational and Industrial Union of Boston, and by Miss Gertrude Bigelow, fellow of the Association of Collegiate Alumnæ, at the School of Housekeeping. They have collected statistics in regard to the hours of labor in domestic service, the social conditions of domestic service, household expenses, and the relative cost of home-cooked and of purchased food. The results of these investigations have been collected by the Massachusetts Bureau of Statistics of Labor, and the reports based on them have been commented on by the press. Scientific information in regard to the subject has thus been widely circulated, and this must have been effective in changing somewhat the attitude of the public mind toward the subject as a whole. Mention must also be made of the “Twentieth Century Expense Book,” prepared by Miss Mary W. Dewson; its widespread use would be of service in affording opportunity for a comparative study of household expenses. It was early recognized that some of the most difficult factors of the problem concerned the intelligence office, and investigations on a somewhat limited scale were carried on in several cities; but, largely owing to political considerations, it was not deemed advisable to publish the results. The most thorough and systematic investigation undertaken in this direction has been that of Miss Frances A. Kellor, whose “Out of Work,” based on a study of more than seven hundred agencies, has laid bare the evils of the present system of securing new employees, as seen by employer, employee, and manager of the agency. A body of facts has thus been made available that must prove of the highest service in any attempt to cope with the notorious evils attending many agencies.
