Southwark Fair was this year extended to four days, so fitful and varying was the policy of the Court of Aldermen with regard to the fairs, which, while they professed to regard them as incentives to idleness and vice, they encouraged in some years as much as they restricted in others. The names of Dunstall and Vaughan do not appear in the bills issued by Warner for this fair, but the comedy performed was the same as at Bartholomew Fair, followed by a representation of the capture of Louisbourg, concluding with a procession of colours and standards, and a song in praise of the heroes of the victory. Yates and Shuter again attended Bartholomew Fair in the following year. Mr. Henry Morley claims for the latter the invention of the showman's device of announcing to the players, by a cant word, that there was another audience collected in front, and that the performances might be drawn to a close as soon as possible. Shuter's mystic words are said to have been "John Audley," shouted from the front. The practice appears, however, to have been in operation in the earliest days of Sadler's Wells, where, according to a description of the place and the entertainments given by Macklin, in a conversation recorded in the fortieth volume of the 'European Magazine,' the announcement was made in the query, "Is Hiram Fistoman here?" It was about this time that the "cat's opera" was announced by the famous animal-trainer, Bisset, whose pupils, furred and feathered, were regarded as one of the most wonderful exhibitions ever witnessed. Bisset was originally a shoemaker at Perth, where he was born in 1721, but, on coming to London, and entering the connubial state, he commenced business as a broker, and accumulated a little capital. Having read an account of a performing horse, which was exhibited at the fair of St. Germain in 1739, he was induced to try his own skill in the teaching of animals upon a dog, and afterwards upon a horse, which he bought for the purpose. Succeeding with these, he procured a couple of monkeys, one of which he taught to play a barrel-organ, while the other danced and vaulted on the tight-rope.
