The state bureaus of labor have in several instances done valiant service to the cause through the official investigations carried on. As far back as 1872 the Massachusetts Bureau of Statistics of Labor devoted four and a half pages of its annual report to domestic labor. But the first real investigation of the subject made by a state bureau of labor was probably that undertaken by the Minnesota Bureau in 1890. This has been followed by special investigations in other states,--notably Kansas and Michigan,--and in Canada. Moreover, it must be remembered that many bureaus, while making no special investigation of domestic service, have incidentally considered the subject in connection with their investigations of general labor questions. Most of all is encouragement to be found in the comprehensive investigation recently carried on under the direction of the Industrial Commission. These investigations enumerated have been of a severely scientific, statistical nature, and have been carried on by state or national organizations. But other studies no less important have been made by organizations of a purely private or of a semi-public character. Notable among these has been the Association of Collegiate Alumnæ, several branches of which have been most active in making studies of domestic service, both as a special field for investigation and also in connection with the larger subjects of home economics and domestic science. Students in colleges and universities have made special studies in the same field, and in some instances have made distinct contributions to the subject. This work has been of most value, however, in the indication it has given of a desire on the part of college-trained investigators to make domestic service a subject of serious consideration. Domestic service has been until very recently a field untouched by the statistician and investigator. The studies already made show not so much what has been done as how much yet remains to be done. But the territory is already being occupied. Trained investigators are mapping out the field, workers are at hand, and in a few years we shall have a body of facts that will afford a sufficient basis for scientific deductions in regard to the condition of domestic service in the entire country. Opinions may honestly differ as to whether it is advisable to substitute in schools and colleges subjects along the line of household affairs for other subjects more properly classed as liberal studies. But it is interesting to note how much has been done in this direction. Courses in household economics have been given in recent years in the state universities of Illinois, Nebraska, Ohio, and Wisconsin, as well as in the Leland Stanford Junior University, while Columbia University through Teachers College has offered similar work.
