It has been said that as in the world of life the localisation of function made the organ subsequently to become responsible for that function, so may the differentiation of labour develop individual talents, just as the exercise of our vital activities has led to the differentiation of parts in a house. Thus, as satisfaction of hunger is a first necessity, eating made the kitchen, where means for the gratification of this instinct were localised. By degrees the growth of men's social and intellectual demands led to the setting apart of a chamber for conversation; that is, the parlour. Storage of bread called the pantry into existence; increased refinement necessitated a scullery for the washing of cups and platters. Centuries, however, elapsed before the enlarging personality of the individual demanded privacy for the toilet and the right to isolate himself periodically from the bustle and publicity of group life. The general provision of separate bedchambers for each unit of a household is not even yet habitual, though most desirable in the interests of health. Reparation of the omission will mark a further phase of social evolution, and will remove one disintegrating force now continually at work in home life. Here again the artist will most advantageously collaborate with landlord and with health authorities to devise means for the suitable satisfaction of this laudable demand. Further objections to the adoption of any comprehensive schemes for training housewives of all ranks are found in the apparent want of time available for the purpose and the prohibitive cost incurred if the period of education be prolonged. The best answers to both objections are found in the movement now active all over Europe and North America to furnish more and fuller opportunities for this training, and to extend, not curtail, its duration. More than this: this movement, which generally originated in the desire to improve home life among the poorest, has recently extended itself just as generally to institutions for higher education, upon whose pupils and students its claims are now recognised. There is no suggestion, for instance, in Germany or England, Norway or the United States, of restricting the education of girls by this movement or of prematurely enforcing upon them technical instruction. The growth of public opinion is due rather to a belated realisation that the end of all education is the betterment of life, and that suggested applications to the practical concerns of daily life in the course of a girl's general education make for the sounder assimilation of theory by the pupil, and are thus contrived a "double debt to pay." The progress of preventive medicine has also introduced another incentive to the diffusion of this training; for it affords convincing proofs that the foundation of the national health is laid in the home. If, however, the foundation is permitted to be imperfect the edifice must necessarily be unstable.
