The Central Lake washes the northern end of the Lower Terrace, and stretches away from it to the east and west. It is without doubt the most beautiful feature of the park. It covers between twenty and thirty acres, and is as pretty a sheet of water as can be found in the country. Upon its upper side are the wooded heights of the Ramble, which in some places slope down gently to the water's edge, and in others jut out into the lake in bold, rocky headlands. The magnificent Terrace, with its fountain and flowers, and carvings, adorns the southeastern portion. To the west of the Terrace the lake narrows very greatly, and is spanned by a light iron structure, called the Bow Bridge, from its peculiar shape. It is used for pedestrians only. Heavy vases filled with trailing flowers adorn its abutments, and from this it is sometimes called the Flower Bridge. The western part of the lake is a lovely sheet of water, and comprises more than two-thirds of the whole lake. Its northwestern end is spanned by a handsome stone bridge, which carries the drive across that part of the lake, and close by is another, picturesquely constructed of wood, which conducts a foot-path across the head of the lake. At the Terrace there is a boat-house, in which is to be found the manager of the fleet of pleasure boats which dot the surface of the water. The regular fare around the lake in the omnibus or public boats is ten cents. Persons may hire a boat for their private use on the payment of a moderate sum. They may either make the circuit of the lake in these boats, or may leave them at any of the six pretty boat-houses which are arranged at convenient points on the shore. The popularity of these boats may be judged from the fact that in 1869, 126,000 persons used them. Whole fleets of snow-white swans are constantly sailing through the waters. They are among the finest specimens of their species in existence. At the opening of the park twelve of these birds were presented to the Commissioners by the city of Hamburg in Germany. Nine of these died, and twelve more were presented by the same city. Fifty others were given by some gentlemen in London. Of the original seventy-four, twenty-eight died, and the remaining forty-six with their progeny form one of the pleasantest attractions of the lake. A number of white ducks have been added to the collection. All the birds are quite tame, and come readily to the call.
