The Federal Department of Labor[7] has studied workingmen’s houses, but _living in the house_ has not been worked up. The housewife has no station to which she may carry her trials, like the experiment stations which have been provided for the farmer. Here is another opportunity for the capitalist to hasten the time when the State will supply these. The way will very soon be laid out and the first steps taken. [7] Bulletin No. 54. For the immediate present some standard of healthful housing is needed, and now that a similar type of house and of apartment house is being built in all cities and towns from one ocean to the other, and from Texas to Maine, such a standard is compatible with conditions. A score card for houses to rent would save much wrangling. The agent shows the card with this house’s rating, and the tenant learns that some of his wishes are incompatible with the standard, and some would mean a much higher rent than he is willing to pay. Professor J. R. Commons, Department of Economics, University of Wisconsin, has devised a score card to serve the house hunter and householder as a standard of comparison. This should serve the house builder as well, indicating what the demand will be forty or fifty years hence. At present the rating stands somewhat as follows: Dwelling, 100 points Location, 18 points out of 100 Congestion of buildings, 26 points Common entrance for two or more, discredit 2 points Basement, discredit 5 points Sunlight, credit 16 points of the 26 Window openings, 11 points Air and ventilation, 13 points Structural condition, 6 points House appurtenances, 26 points Well outside, discredit 3 points The final score card may vary somewhat. For rent collectors there is also a score card. Occupants, 100 points Congestion of occupancy, 61 points cubic air space 1,000 cu. ft. per person, no discredit 600 cu. ft. per person discredits 20 points Condition of air and ventilation, 18 points Cleanliness, 21 points A score card movement might be started as a hobby, and in the end lead public opinion to judicial choice and action. No such movement, however, is possible without leaders, and leaders of the right type. The lesson for the community to be drawn from a study of crowd psychology is that of leadership and loyal coöperation. The common man is likely to be possessed of one idea at a time. If such an one becomes a leader, there is danger that equally vital factors will be overlooked. Safety is found in a combination of leaders to make an all-round improvement.
