These are located in the upper Park, and cover a considerable area. From the hill on which they are situated, a fine view can be had of the lower Park, stretching away in its beauty for over a mile. These reservoirs receive the water direct from the aqueduct, which brings it from Croton Lake, and pass it into the distributing reservoir on Forty- second street. The scenery of this part of the Park is wild and romantic. It is said that "the deep gorge, called McGowan's Pass, dividing this northern portion, is the valley which, by means of its darkly wooded hillsides, sheltered the secret messengers passing between the scattered parties of the American troops who, during the few days intervening between their disheartening rout on Long Island and the battle of Harlem Plains, rallied about the range of hills extending from Fort Washington to Bloomingdale." A small part of the "Old Boston Road" is still to be seen in this portion of the Park, and in the distance a view is obtained of the High Bridge and Westchester county, while Washington Heights rise beautifully to the northward. To the eastward we see the white sails of the vessels in Long Island Sound, and get a faint glimpse of the town of Flushing on Long Island, and New Rochelle on the mainland. TRANSVERSE ROADS. It was foreseen when the Park was laid off, that as it would extend for so long a distance right through the centre of the island, it would be necessary to provide means of communication between the eastern and western sides of the island, without forcing persons to pass around the upper or lower ends of the enclosure. At the same time it was felt to be desirable to make these roads as private as possible, so that the beauty of the Park should not be marred by them, or by the long trains of wagons, carts, and such other vehicles as would pass over them. The genius of the constructing engineers soon settled this difficulty. A system of _transverse roads_ was adopted and carried out. There are four of them, and they cross the Park at Sixty-fifth, Seventy-ninth, Eighty-fifth, and Ninety-seventh streets. They are sunken considerably below the general level of the Park, and are securely walled in with masonry. Vines, trees and shrubbery are planted and carefully trained along the edges of these walls, which conceal the roads from view. The visitors, by means of archways or bridges, pass over these roads, catching but a momentary glimpse of them in some places, and in utter ignorance of them in others. THE ZOOLOGICAL GARDEN.
