A WONDERFUL WORK.

The Central Park, so called because it is situated almost in the centre of the island, is a parallelogram, and lies between Fifth and Eighth Avenues, and Fifty-ninth and One-hundred-and-tenth streets. It covers an area of eight hundred and forty three acres, and is about two and a half miles long by half a mile in width.

When the site was selected and the work commenced, the whole area, with the exception of the Croton Reservoirs in the upper part, was a barren waste. It was a succession of rocky elevations, stagnant pools, and sandy plains. It was covered with a coarse undergrowth, which simply disfigured it, and was occupied by the miserable shanties of a number of Irish families, known as "squatters." By looking at the character of the land surrounding it, the reader can easily form a correct idea of the primitive character of the Park, and of the immense labor which has been performed in transforming that barren waste into the magnificent grounds of to-day.

As it was morally certain that the authorities of the city of New York would not carry on the work as honestly and as promptly as was desirable, the Legislature placed the management of affairs in the hands of a Commission, composed of prominent citizens of all parties. Under the auspices of this Commission, the work was begun in 1858, and pushed forward as rapidly as possible, to its present state. These Commissioners still have charge of it, and conduct its affairs with the same skill and vigor which have accomplished so much in the past.

The Park now contains a parade ground of fifty acres, for the manoeuvering of large bodies of troops, play grounds, base ball grounds, rides, drives, walks, etc. There are nine miles of carriage roads in it, four miles of bridle roads, and twenty-five miles of walks. It is larger than any city park in the world, except the Bois de Boulogne at Paris, the Prater at Vienna, and the Phenix Park 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 form 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.

All the entrances on Fifty-ninth street lead to the handsome marble arch near the eastern side. Passing through this archway, and ascending a broad flight of stairs, the visitor finds himself in the great mall, which, beginning near the principal entrance on Fifth Avenue, leads to the terrace, which is one of the chief attractions. The terrace is handsomely constructed of a soft yellow stone, carved elaborately and tastefully. Three broad flights of stairs, one on each side, and one covered stairway in the centre, lead to the esplanade below, in which is the main fountain, and at the end of which is the lake.
