Towards what limits must the city grow. . . .? How much and what portions . . . will be required for business purposes . . . ? . . . Where will the rich man’s city place stand? Where will the laborer’s family rest? . . . What avenues of communication are needed between the sections for business and those for residence? How shall the latter be connected with the great park, and with other healthful and pleasant resorts? . . . Ought . . . the city have . . . one great “Central Park”; or are a number of parks required in different sections . . . ? Can any means be devised to make such places attractive to those who need them most; . . . those who are suffering from the . . . close air of shops and factories?
