A single family cannot control a whole street, although cooperation can accomplish a great deal in the way of congenial neighborhoods. But the risk involved, the liability to error of judgment, as well as the large outlay of capital, at once prevents the adoption of this means of satisfactory housing for the business and professional class to any great extent, at least in the city. The acumen needed to discover the profitable in real estate, the skill to acquire large contiguous tracts of land, both belong to the capitalist. Only when he is a philanthropist besides, is the housing question safe in his hands. Such an example we find in the Morris houses, Willoughby Ave., Brooklyn, N.Y. This set of family dwellings was put up to meet this very need. Congenial neighborhood, safe playgrounds for the children, labor-saving devices for the housekeeper. When first built they were in advance of anything in an eastern city of their class. To-day Mr. Pratt has even more advanced ideas which will take form in the future. [Illustration: Aerial-view Drawing: The Morris Building Company's Block of Single Houses, with Central Heating Plant, Brooklyn, New York.] These attractive and comfortable houses, so near the working places of the teachers and professional and business men who occupy them, were possible only because of the comparative cheapness of the land, which had been held undesirable for high-class single houses, not for sanitary reasons, but solely on account of social conditions. This cluster of forty houses makes its own atmosphere. This is the lesson to be learned. Let groups of like-minded families make their own surroundings. The capitalist will soon learn where his interest lies.

Whatever form the advance may take, this is a sign-post in the right direction. In the nature of things, however, the first experiments will be costly and must be combined with business of a sure kind. In this instance the heating and hot-water supply was made possible by a combination with factory plant. But if a larger group of, say, one hundred houses were run by a central establishment, the Morris Building Company estimates the cost at about fifty dollars per year.
