The care of the sidewalk, stairs, central hall, and the management of the heating apparatus, will be in the charge of a janitor, as is customary in the ordinary apartment hotel, thus almost doing away with the work of one servant in each family. In addition to the great advantage of having all the rooms on one floor, these rooms will be larger and more airy than in the ordinary block house. Then, too, they will not only be more in number than those in the average flat, but they will be more than in the vertical house of the same cubical contents. For the space heretofore devoted to stairs can now be utilized for living-rooms, and by simply opening the doors and windows a draught of air can sweep straight through from front to back of the house. There will be neither dark rooms nor rooms opening into a dismal brick air-well, as in most of our modern flats, and, consequently, none of that cramped, confined feeling that one always experiences when going into their tiny rooms which seem designed for a family of three members only, and where children have no right to be. Now I propose to offer this horizontal dwelling, with its eighty-two feet front, and its yard at the back, with all its economy of space and expense and physical exertion, for _precisely the same rental_ that the vertical house with its twenty-three feet of front would cost. And, as I want permanent tenants, and desire to make them practically the same offer as a sale of the property would be, you may give, to any one who desires it, a lease for fifteen or twenty years. Doubtless before that time has expired we shall come to see that our methods of living must be modified still more, and separate kitchens and laundries will be relegated to the country, while some system of coöperation will come into vogue in our cities. If so, such a house as I propose to build can be easily modified to suit the new order of things. The kitchens above could be metamorphosed into bedrooms, and part of the space in the basement turned into a cooking centre for all the families. If this experiment should prove a success,—and I can see no reason now why it should not,—this will be but the beginning of what I intend to do on a large scale. I think I can do no better service for the hurried, overworked wives and mothers of our great cities, than to simplify and lighten the burdens of housekeeping, by adding to their comfort without adding to their expense. I want very little frescoing and gilding in these houses, but there must be fire-escapes at the rear, and every device for convenience that is available.
