It is at this point that some consideration of domestic service naturally presents itself. Though regarded often as no part of the labor question, there can be no other head under which to range it, since the last census gives over a million persons engaged in this occupation, the lowest rough estimate of wages being $160,000,000 and the support included forming a sum at least as large. It is through the hands of the domestic servant that a large part of the finished products of other forms of labor must pass, and the economic aspects of the question grow in importance with every year of the changing conditions of American life. In no other occupation is a just consideration of the points involved so difficult a task, since the mistress who faces the incompetence, insubordination, and all the other trials involved in the relation, suffers too keenly from the sense of individual wrong to treat the matter in the large. Till it is so treated, however, understanding for both sides is impossible, and to bring about such understanding is the first necessity for all. From the employer's standpoint the advantages to be stated are as follows: First and most obvious is the fact that wages are not only relatively but absolutely high; for aside from the actual cash there are also board, lodging, fuel, light, and laundry, all of which the worker in trades must provide for herself. There is no capital required, as for type-writer, sewing-machine, or any appliances for work, nor is the girl forced to expend anything in preparation, since under the present system housekeepers take her untrained fresh from Castle Garden, and willingly give the needed instruction, at the same time paying the same wage as that given to competent service. Professor Lucy Salmon, of Vassar, who has devoted much time to this subject, reports that, on examination of testimony from three thousand employees, it is found that on a wage of $3.25 a week it is possible to save annually nearly $150 "in an occupation involving no outlay, no investment of capital, and few or no personal expenses." The wages received are relatively higher than those of other occupations; for in Professor Salmon's comparison of wages received by three thousand country and the same number of city employees it was found that of six thousand teachers in the public schools the average salary actually paid is less than that paid to the average cook in a large city. The second advantage lies in the healthfulness of the work, which includes not only regularity but variety; the third, that a home, at least in all externals, is insured; the fourth, that a training which makes the worker more fit for married life is certain; and a fifth, that the work is congenial and easy for those whose tastes lie in this direction.
