"But to return to the sparrows. There have been so many flights of them let loose in this opera, that it is feared the house will never get rid of them; and that in other plays they may make their entrance in very wrong and improper scenes, so as to be seen flying in a lady's bedchamber, or perching upon a king's throne; besides the inconveniences which the heads of the audience may sometimes suffer from them. I am credibly informed, that there was once a design of casting into an opera the story of 'Whittington and his Cat,' and that in order to it there had been set together a great quantity of mice, but Mr. Rich, the proprietor of the playhouse, very prudently considered that it would be impossible for the cat to kill them all, and that consequently the princes of the stage might be as much infested with mice as the prince of the island was before the cat's arrival upon it, for which reason he would not permit it to be acted in his house. And, indeed, I cannot blame him; for as he said very well upon that occasion, 'I do not hear that any of the performers in our opera pretend to equal the famous pied piper who made all the mice of a great town in Germany follow his music, and by that means cleared the place of those noxious little animals.' "Before I dismiss this paper, I must inform my reader that I hear that there is a treaty on foot between London and Wise,[17] (who will be appointed gardeners of the playhouse) to furnish the opera of _Rinaldo and Armida_ with an orange grove; and that the next time it is acted the singing birds will be impersonated by tom tits: the undertakers being resolved to spare neither pains nor money for the gratification of their audience."
