There is increasing evidence of a tendency in this country to take advantage of these opportunities to intelligently direct and control the growth of cities. The purely mechanical extension of existing street systems is giving way to scientific methods of land development based on a careful study of the probable economic, social, and esthetic needs of the prospective inhabitants. The present volume, consisting mainly of plans submitted in a competition held by the City Club of Chicago in 1913, is issued in the hope that it may help to stimulate interest in the more intelligent planning of the outlying portions of large cities.
