The curtailment of space in which families live is going on at an alarming rate, although not yet seriously taken into account by the sociologist for the group we are studying. [Illustration: Figs. 8 and 9.--House for "Mrs. L.," Anywhere in temperate America, to cost $5000, if it must not more (*remainder cut off).] [Illustration: Figs. 10 and 11.--House for "Mrs. L.," Anywhere in temperate America, to cost only $3000, if possible. (Josselyn & Taylor Co., Cedar Rapids, Iowa).] This crowding is causing the refinements of life to be disregarded, is depriving the children of their rights, and doing them almost more harm than comes to the tenement dwellers, for they have the parks to play in and are not kept within doors. Mr. Michael Lane in his "Level of Social Motion" claims that present tendencies are leading to a level of $2000 a year and a family of two children as an average. Mr. Wells claims as a tendency in living conditions the practically automatic and servantless household. In connection with the Mary Lowell Stone Home Economics Exhibit a design of an approach to this kind of a dwelling was asked for in sketch. The accompanying plans were made by a firm who have had not only experience in this kind of domestic building, but who have sympathy with and personal knowledge of similar conditions in widely separated parts of the country. These sketches are not of an _ideal_ house and not for a given plot of land, but only a hint of what Mrs. Michael Lane "must expect if she attempts to build in the country or suburbs." Since these were drawn many changes have come about in costs and in materials available. The architects expressly disclaim the word "model" in relation to them. Mrs. Lane and her two children will do their own work, and therefore steps and stairs must be few, and yet they wish light and air and cleanliness. The author hopes that her readers will make a study of house-plans, not the cheap ones, but those that will bear the test of time and living in. The increased cost of shelter should mean both more comfort and greater beauty. If it does not, something is wrong with society. It appears from all that has been gathered that single houses for a family of five will cost about $5000 to $10,000 for some years to come; that these houses should be so constructed and cared for as to rent for $300 to $400 if the occupant is to keep the grounds in order, to use the house with care, and furnish heat and light. The question of return on capital invested and of care of exteriors and grounds must be studied most carefully in the light of the new conditions, and a new set of conventions devised by society to meet the various circumstances arising out of them.
