Three other theaters which were identified with opera more or less came into the field later, and by their names, at least, testified to the continued popularity which a famous English institution had won a century before, and which endured until that name could be applied to the places that bore it only on the "lucus a non lucendo" principle. These were the theaters of Richmond Hill, Niblo's, and Castle Garden. The Ranelagh Gardens, which John Jones opened in New York, in June, 1765, and the Vauxhall Gardens, opened by Mr. Samuel Francis, in June, 1769, were planned more or less after their English prototypes. Out-of-doors concerts were their chief musical features, fireworks their spectacular, while the serving of refreshments was relied on as the principal source of profit. Richmond Hill had in its palmy days been the villa home of Aaron Burr, and its fortunes followed the descending scale like those of its once illustrious master. Its site was the neighborhood of what is now the intersection of Varick and Charlton streets. After passing out of Burr's hands, but before his death, the park had become Richmond Hill Gardens, and the mansion the Richmond Hill Theater, both of somewhat shady reputation, which was temporarily rehabilitated by the response which the fashionable elements of the city's population made to an appeal made by a season of Italian opera, given in 1832. The relics of Niblo's Garden have disappeared as completely as those of Richmond Hill, but its site is still fresh in the memory of those whose theatrical experiences go back a quarter of a century. They must be old, however, who can recall enough verdure in the vicinity of Broadway and Prince Street to justify the name maintained by the theater to which for many years entrance was gained through a corridor of the Metropolitan Hotel. Three-quarters of a century ago Niblo's Garden was a reality. William Niblo, who built it and managed it with consummate cleverness, had been a successful coffee-house keeper downtown. Its theater opened refreshingly on one side into the garden (as the Terrace Garden Theater, at Third Avenue and Fifty-eighth Street does to-day), where one could eat a dish of ice cream or sip a sherry cobbler in luxurious shade, if such were his prompting, while play or pantomime went merrily on within. Writing of it in 1855 Max Maretzek, who, as manager of the Astor Place Opera House, had suffered from the rivalry of Niblo and his theater, said:
