Nearly a quarter of Central Park is occupied by its various bodies of water. These have their ornamental and their practical side. The latter is of course represented by the reservoirs that receive the principal portion of the water supply brought down by the Croton aqueduct. There is a smaller double basin (now being deepened) in the center of the park opposite Eightieth Street, overlooked by the Belvedere, and the main reservoir that fills nearly the whole of the space between Eighty Sixth and Ninety Sixth Streets, and forms the division between the North Park and the South Park. That this big pond, pretty nearly half a mile in length and in width, adds nothing to the attractions of the park, few who have walked or ridden along its border will maintain. [Illustration: CHILDREN AND NURSES IN THE PARK.] Of the ornamental waters the Lake—so called _par excellence_—is the chief. The effect with which irregularity of outline may be used to add to apparent size is well exemplified by comparing this with the reservoir. Take a boat on the upper part of the Lake, near the foot of the Terrace, row under the bridge across the strait into its lower expanse, and continue to the furthest extremity of the creeks that open into it, and you will hardly guess that the whole sheet of water measures but twenty acres, while the Croton reservoir covers more than a hundred. You will also be likely to think that you have found a remarkably pleasant place for a row, especially if your expedition is made in the dusk of a summer evening, when the red lanterns that glow dimly in the bows of the boats make a picturesque scene which is often pronounced to be “just like Venice” by those who have never been in that city of watery streets. [Illustration: A “TALLY HO” IN CENTRAL PARK—THE FAVORITE VEHICLE OF THE JEUNESSE DORÉE.] The other lakes are the Pond, near the Fifty Ninth Street entrance, on which ply the swan boats; the Conservatory water near Fifth Avenue and opposite Seventy Fourth Street; and three in the North Park—Harlem Mere, in the northwestern corner, and the two miniature lakelets called the Pool and the Lock. The swan boats are by no means the park’s only attraction especially designed for children. There are the swings and merry-go-round of the carrousel, and the little carriages that are drawn up and down the Mall by well trained goats. The menagerie, too, is a source of never failing wonder and amusement. There is always a crowd, in which young people predominate, watching the monkeys, gazing with something like awe at Tip, the huge elephant who has murdered more than one of his keepers, or throwing peanuts and similar esculents to the more docile pachyderm whose quarters are in the neighboring cage.
