This report does not go into details of the roadways and stations, either trunk or intramural. Routes are suggested which seem to be the natural and logical ones. The expert engineers will find the best solutions of the constructive and mechanical problems as they arise. But all citizens are interested to see that the best and most comprehensive general schemes shall be adopted, and that in carrying out of any one of them, every detail shall be designed and executed with regard to its effect on the senses as well as on the basis of mere mechanical or constructive excellence. A million Chicago people who habitually use railway facilities will possess a higher average of good citizenship when the irritation of nerves is reduced to the minimum, and within a few years most of the waking hours of a million Americans will be spent in the business center of Chicago, where unpleasant sights and sounds should be abolished. The community will get far more out of its million workers when their nerves cease to be wracked by irritating conditions. [Illustration: LXXX. CHICAGO. DIAGRAM OF CITY CENTER, SHOWING THE PROPOSED ARRANGEMENT OF RAILROAD PASSENGER STATIONS, THE COMPLETE TRACTION SYSTEM, INCLUDING RAPID TRANSIT, SUBWAY, AND ELEVATED ROADS, AND THE CIRCUIT SUBWAY LINE. The last is designed,—(A) To connect all railroad stations with one another. (B) To connect passengers from all points of the city within and without the center with the railroad stations by transfer from the subway line proposed in the Arnold Report. (C) To supplement by transfer the interchange of passengers from traction lines going through the center from the North, South, or West to any point in the city.

These conditions actually cause misery to a large majority of people who are subjected to the constant strain, and in addition they undoubtedly cause a heavy aggregate loss of money to the business community. For the sake of the state, the citizen should be at his best, and it is the business of the state to maintain conditions conducive to his bodily welfare. Noises, ugly sights, ill smells, as well as dirty streets and workshops or offices, tend to lower average efficiency. It does not pay the state to allow them to continue. Moreover, citizens have pride in and loyalty to a city that is quiet, clean, and generally beautiful. It is not believed that “business” demands that our present annoying conditions be continued. In a state of good order all business must be done better and more profitably. With things as they should be, every business man in Chicago would make more money than he does now.
