The question of creating pleasing conditions in a suburb is not primarily a matter of money, but of thoughtful co-operation. Even the real estate agent is beginning to discover that by cutting off somewhat from the depth of his lots he can get park space that will make his land more available; and by a combination treatment he can secure for a group of houses an enjoyable area of green grass, to take the place of the narrow and ill-kept back yards which are at once unsightly and unsanitary. In every town a public improvement commission should be formed to bring about the most orderly conditions within the town itself, and especially to act in co-operation with similar bodies in neighboring towns so as to secure harmonious, connected, and continuous improvement. If we take arbitrarily a radius of sixty miles from the heart of Chicago and count all the territory in the semi-circumference as having definite relations with the city, the distance from center to circumference is no greater than the present suburban electric lines extend, or the automobilist may cover in a drive of two hours. The traffic over the ways leading to and from the city is already large and steady; and the near-by towns and villages along these thoroughfares may confidently look forward to the day when the tide of Chicago’s growth will envelop them, and ultimately incorporate them in the city. Hence two considerations become all-important: first, the improvement of the thoroughfares, not only those leading to the great city, but also those which now form the connections between towns and which ultimately will appear as convenient diagonals within the city itself; and secondly, the arrangement of the streets of the town, together with provision for space for the public and semi-public buildings, and sufficient park and playground area, obtained while land is comparatively inexpensive. The suburban movement of population will necessarily increase as the ground and buildings within the business area of the city become so valuable for commercial purposes as to preclude their use for dwellings. In the city of London a thousand policemen are detailed to guard the five thousand and more buildings left entirely empty each night. More than one-fifth of all the buildings in the “city” are thus left vacant at night and on Sunday. Moreover, London, in order to carry out improvements made to prevent congestion, finds it necessary to remove and rehouse the working people who are displaced by tearing down buildings in the over-crowded quarters. On the site of the old Millbank prison four thousand persons removed at the time of the Holborn to Strand improvement were rehoused in convenient new dwellings built by the municipality; and more than fifty thousand people have been displaced and reinstated by reason of the various improvements. Thus the city, while drawing from the farms and small towns, also sends out swarms to be housed under more wholesome conditions.
