All these investigations and educational measures have been undertaken in the belief that household employment has its economic side, like other forms of industry. The widespread recognition of this fact has been a most significant advance, since earlier discussions of the subject had considered only the ethical factors involved. But an interesting reversion to the more purely ethical consideration of the question has been seen in the various efforts to follow the injunction of Charles Reade: “Put yourself in his place.” A number of young women have entered domestic service in disguise, and from personal experience have narrated the life of a domestic employee. It may well be questioned whether the actual results reached are commensurate with the effort expended;--the experiment has meant months of unnatural life and strained relationships, and in the end we probably know little more in regard to the condition of domestic employees than could be known by turning the inner light of our own consciousness on our own households and those of our acquaintances. But the experiment has been interesting as indicative of a determined effort to look at the subject from every point of view. It is not surprising, in view of all the agitation of the question in our own country, to find that a similar interest has been aroused elsewhere. In Germany, that home of conservatism in all domestic affairs, an elaborate statistical investigation has been carried on by Dr. Oscar Stillich, and its results published in an exhaustive work entitled “The Status of Women Domestics in Berlin.”[9] Nor again is it surprising to find that neither official nor domestic Berlin has taken kindly to the investigation, since bureaucracy has in it no place for private initiative, and the _Kinder, Küchen, Kirchen_ theory of domestic life has resented what has been deemed unwarranted interference in private affairs. But it is a matter of congratulation that the author has been of undaunted courage, and that his work stands as a thoroughly scientific investigation, and therefore the most valuable contribution yet made in any country to the theory and condition of domestic service. Two things of special encouragement must be noted. One is the changing attitude of domestic employees themselves toward their own occupation, and the other is the introduction of men into a field where it has always been held that by divine ordinance women ruled supreme.
