The Central Park, so called because it is situated almost in the centre of the island of Manhattan, is a parallelogram in shape, and lies between Fifty-ninth street on the south, and One-hundred-and-tenth street on the north, the Fifth avenue on the east, and the Eighth avenue on the west. It covers an area of 843 acres, and is about two and a half miles long, by half a mile wide. There are nine miles of carriage drives, four miles of bridle roads, and twenty-five miles of walks within its limits. It is the second park in the Union in size; the Fairmount Park at Philadelphia being the largest. It is larger than any city park in Europe, with the exception of the Bois de Boulogne at Paris, the Prater at Vienna, and the Phoenix at Dublin. A rocky ridge, which traverses the whole island, passes through almost the exact centre of the grounds, and has afforded a means of rendering the scenery most beautiful and diversified. A part of the grounds forms a miniature Alpine region; another part is the perfection of water scenery; and still another stretches away in one of the loveliest lawns in the world. The soil will nurture almost any kind of tree, shrub, or plant; and more than one hundred and sixty thousand trees and shrubs of all kinds have been planted, and the work is still going on. Any of the principal walks will conduct the visitor all over the grounds, and afford him a fine view of the principal objects of interest. The park is divided into two main sections, known as the Upper and Lower Parks, the two being separated by the immense Croton Reservoirs, which occupy the central portion of the grounds. Thus far the Lower Park has received the greatest amount of ornamentation. It is a miracle of exquisite landscape gardening. Its principal features are its lawns, the Pond, the Lake, the Mall, the Terrace, the Ramble, and the Museum of Natural History. The main entrances are on Fifty-ninth street, those at the Fifth and Eighth avenues being for vehicles, equestrians, and pedestrians, and those at the Sixth and Seventh avenues for pedestrians only. All these entrances will ultimately be ornamented with magnificent gateways. Paths leading from them converge at the handsome Marble Arch at the lower end of the Mall. Near the Fifth avenue gate is a fine bronze colossal bust of Alexander Von Humboldt, the work of Professor Blaiser of Berlin, which was presented to the park by the German citizens of New York, and inaugurated on the 14th of September, 1869, the one-hundredth anniversary of the birth of the great man. Near the Eighth avenue gate is a bronze statue of Commerce, the gift of Mr. Stephen B. Guion.
