The police cannot patrol every foot of the big expanse of the park, though at times they have had remarkable success in keeping crime at a minimum by dressing a couple of boyish detectives in women's clothes and turning them loose on the scum. The place is, of course, a happy hunting ground for psychopathic and physical irregulars, who find it an excellent layout to strike up acquaintances with others of their kind. The southwest corner of the park, at Columbus Circle, has been pre-empted by Negro homos. The north border, Cathedral Parkway (110th) is alive with wicked wenches. And yet, graceful old Central Park is one of the most beautiful places remaining in this modernist crazy world. Its lights, architecture and landscaping retain the pre-rococo charm of the last century. But the old Central Park Casino is gone, a victim of the leveling-down process of the dictatorship of the rabble. Here, in a charming building surrounded by trees and the greensward, was one of New York's showspots of the hectic 20's where society and café society dined, danced and broke the dry law. As Jimmy Walker's night city hall (he rarely arose in time to visit the official one), the casino attracted the cream--and the sour milk--of New York officialdom and gangdom. Its prices were outrageous, but its food divine, its liquor bona fide and its dance music memorable. LaGuardia, darling of the déclassé, elected in 1933 on a platform of revenge and revulsion against civilized living, made the destruction of the Central Park Casino the first major issue in his campaign of social nihilism. He said the land was needed for a play-ground. No sooner was the casino leveled than he found an excuse to open another dining and dance pavilion in the park, for concessionaires more friendly to his regime. To do this he destroyed the historic old sheepfold, where generations of city kids learned about nature watching the grazing lambs, and turned the building into a cabaret called "The Tavern on the Green." Though its prices are not as astronomical as those imposed by the mourned casino, they are still too high for New York's millions of low-income citizens--the voters LaGuardia said the park was for. Tucked away on a crosswalk in the 60's is a crazy little carousel, circa last century. Here the kids ride the merry-go-round to a tinkly, wheezy calliope playing the same tunes heard there by Teddy Roosevelt. Here is one of New York's most delightful nooks for romance. You still find the hackies at 59th Street and Fifth Avenue, the last of their kind in the country. Best time to ride is after 4 A.M., when the motor traffic in the park has come to a standstill and you have the place all to yourself in a barouche or hansom. If your doll still holds out, after winding slowly through leaf-covered roads, to the tune of the horse's cloppety-clop, wake up the driver and order him right to the morgue. She's dead. 14.
