ABSTRACT
"City planning" means different things to different segments of the city's population. Trees are planted in the space assigned for sidewalks, where at first, while they are saplings, and the vicinity is rural or suburban, they are not much in the way, but where, as they grow larger, and the vicinity becomes urban, they take up more and more space, while space is more and more required for passage. "An intelligent city plan for the future will provide not only better means of communication, but it will provide for the spread of that system of breathing-spots laid out by Penn. When the city devised a new city-wide zoning code the real estate board was asked to appoint a committee of its members to work with the planning department. In Boston, as Walter Firey's account shows, the Common carries such a freight of symbolism as to maintain the area against the direct invasion of business enterprises.
