of the city in acquiring the ground was to control it against such occupations as would peril its water supply, and its permanent disposition is not fully determined. Appropriations have been already made for two large reservoirs, for pumping works, and for a zoölogical garden. No measure has yet been taken looking to the permanent preservation or special preparation of any considerable part distinctly as a park; but drives, rides, and walks have been formed, mainly temporary, by which all parts are traversed or laid open to view. Several houses which were originally private villas are used as refectories; the river is well adapted to pleasure boating; the spaces are so large that few restrictions on the movements of visitors are necessary; and in spite of the defects to which allusion has been made, the ground offers better and larger opportunities for popular rural recreation than are possessed in a single property by any other city in the world. Druid Hill park in Baltimore, of 600 acres, is a very beautiful old wood, acquired by the city in 1860, the original private improvements of which have been enlarged and extended for public use. Buffalo is forming the most complete system of recreation grounds of any city in the United States. It will consist of an inland suburban park of 300 acres, of very quiet rural character, with an ample approach from the centre of the city, and parkways 200 ft. wide extending from it in opposite directions, one to a promenade overlooking Lake Erie, the other to a parade ground and a garden on the opposite side of the town. There is a fine natural growth of trees in the main park, a lake of 46 acres has been formed, and several miles of fair macadamized roads and walks constructed, together with various suitable buildings. The work was begun in 1871, and has been advanced very steadily and economi- cally. The aggregate area of ground occupied, including the parkways, is 530 acres. Chicago is situated in a region most unfavorable to parks, and should she ever have any that are deserving the name, it will be because of a persistent wisdom of administration and a scientific skill as well as art in the constant management of those which she is setting about, such as has been nowhere else applied to a similar purpose. The grounds appropriated are flat, poor in soil, and devoid of desirable natural growth, or, except two which look upon Lake Michigan, of any natural features of interest. In one it is proposed to transform a series of marshes partly overflowed by high water of the lake into lagoons, the quiet water surface of which is designed to take the place ordinarily given to lawns in sylvan landscapes; this, if the idea is consistently carried out, will be unique and interesting. The Chicago park system contains nearly 1,900 acres of land in six parks of an average extent of 250 acres each, three in one chain, and all with one exception connected by parkways. About 20 m. of parkway, from 200 to 250 ft. wide, has been laid out (in the city and suburbs), nearly half of which is already provided with good macadamized or concrete roads and well planted. St. Louis now controls 2,100 acres of lands held for recreation grounds, of which about 100 are in place parks, the greater part improved and in use, and the remainder suitable for parks proper, the smallest field being of 180 acres and the
