An occasional display of fireworks took place, and the gardens and a cascade (introduced about 1792) were illuminated.[258] From time to time there was a representation of the Siege of Gibraltar by means of fireworks, transparencies and bomb shells.[259] The apparatus for the Siege, which was designed by Keyse himself, was set up in a field divided from the lawn by a sunk fence, the rock being fifty feet high and two hundred feet long. The blowing up of the floating batteries and the sinking of boats in ‘fictitious water’ were (we are assured) ‘so truly represented as to give a very strong idea of the real Siege.’ A permanent attraction was the Gallery of Paintings, an oblong room described as being about the same size as W. M. Turner’s studio in Queen Anne’s Street. Here were exhibited Keyse’s pictorial reproductions of a Butcher’s Shop and a Greengrocer’s Stall and many other paintings, including a Vesuvius, and a candle that looked as if it were really lighted. On the whole, the Bermondsey Spa appears to have been a respectable, though hardly fashionable, resort, which brought its proprietor a moderate income and supplied harmless, if not very exalted, means of recreation. It being not unnecessary to provide for the safe convoy of the visitors after nightfall, Keyse inserted the following advertisement in the newspapers:--“The Spa Gardens, in Grange Road, Bermondsey, one mile [the distance is rather understated] from London Bridge; for the security of the public the road is lighted and watched by patroles every night, at the sole expense of the proprietor.” The lighting and patrolling were probably somewhat mythical, but no doubt the announcement served to reassure the timid. J. T. Smith, the author of _A Book for a Rainy Day_, has left a graphic description of a visit that he paid on a bright July evening of 1795. The popularity of the gardens was then waning, and on entering he found no one there but three idle waiters. A board with a ruffled hand within a sky-blue painted sleeve directed him to the staircase which led “To the Gallery of Paintings,” and he made a solitary tour of the room.
