This suburban living is the vital point to be attacked, because in cities the matter is already pretty well settled; there is in sight nothing that will greatly change the rule already given, a cost of $1000 per room of about 1200 cubic feet, with the finish and sanitary appliances demanded. Our family of five must pay for rent $500 to $800 for the smallest quarters they can compress themselves into. Subtracting the cost of heat and light and the car-fares, this may be no more expensive than the suburban house at $300 or $400, _but_ the difference comes in light and air. The upper floors of an isolated skyscraper give more than a country house, but at the expense of other houses in the darkened street. In the city the question is then not so much one of cost of construction as of a fair arrangement of streets and parks, so as to avoid the loss of light and air for living-places. The single individual may find shelter of a safe and refined sort in all respects except air for $200 to $300 a year in the newer apartment-houses, and two friends to share it may halve this sum. A great need is for as good rooms to be furnished in the suburbs where more light and air may be had. The content of the country house costing $5000 to $10,000 will be approximately 50,000 to 70,000 cubic feet, or 10,000 for a person. The suburban block will furnish about 12,000 to 20,000 for the family, while the city apartment of six so-called rooms renting for from $400 to $500 a year shrinks to 6000 to 8000 cubic feet, giving only one tenth the air-space the country house affords, as well as far less outside air and sunshine. The best city tenements cost $1 a week for 600 cubic feet air-space. What wonder that the sanitarian is aghast at the prospect! According to the President of the English Sanitary Inspectors' Association it seems probable that if the nineteenth-century city continues to drain the country of its potentially intellectual class and to squeeze them into smaller and smaller quarters, it will dry up the reservoirs of strength in the population (address, Aug. 18, 1905). The houses of the Morris Building Co., illustrated in Chapter II, show what may be done. These houses rent for $35 to $45 a month with constant heat and hot water, so that the heavy work is reduced to a minimum; but the exigencies of family life are illustrated in the fact of the almost universal demand of the tenants for continuous heat and hot water night as well as day. The ordinary childless apartment house banks its fires at night. A supplementary apparatus would mean work by the tenants, however. This is a good example of the balance which must be struck in all new plans until they are tested.
