Chicago has a physical peculiarity that radically affects its social condition, and prevents its becoming homogeneous. It has one business centre and three distinct residence parts, divided by the branching river. Communication between the residence sections has to be made through the business city, and is further hindered by the bridge crossings, which cause irritating delays the greater part of the year. The result is that three villages grew up, now become cities in size, and each with a peculiar character. The north side was originally the more aristocratic, and having fewer railways and a less-occupied-with-business lake front, was the more agreeable as a place of residence, always having the drawback of the bridge crossings to the business part. After the great fire, building lots were cheaper there than on the south side within reasonable distance of the active city. It has grown amazingly, and is beautified by stately bouses and fine architecture, and would probably still be called the more desirable place of residence. But the south side has two great advantages—easy access to the business centre and to the great southern parks and pleasure-grounds. This latter would decide many to live there. The vast west side, with its lumber-yards and factories, its foreign settlements, and its population outnumbering the two other sections combined, is practically an unknown region socially to the north side and south side. The causes which produced three villages surrounding a common business centre will continue to operate. The west side will continue to expand with cheap houses, or even elegant residences on the park avenues—it is the glory of Chicago that such a large proportion of its houses are owned by their occupants, and that there are few tenement rookeries, and even few gigantic apartment houses—over a limitless prairie; the north side will grow in increasing beauty about Lincoln Park; and the south side will more and more gravitate with imposing houses about the attractive south parks. Thus the two fashionable parts of the city, separated by five, eight, and ten miles, will develop a social life of their own, about as distinct as New York and Brooklyn. It remains to be seen which will call the other “Brooklyn.” At present these divisions account for much of the disorganization of social life, and prevent that concentration which seems essential to the highest social development. In this situation Chicago is original, as she is in many other ways, and it makes one of the interesting phases in the guesses at her future. X.—CHICAGO [Second Paper.]
