practised upon his Mistress; for, though they flew in Sight, the Musick proceeded from a Consort of Flagellets and Bird-calls which was planted behind the Scenes. At the same time I made this Discovery, I found by the Discourse of the Actors, that there were great Designs on foot for the Improvement of the Opera; that it had been proposed to break down a part of the Wall, and to surprize the Audience with a Party of an hundred Horse, and that there was actually a Project of bringing the
New River
into the House, to be employed in Jetteaus and Water-works. This Project, as I have since heard, is post-poned 'till the Summer-Season; when it is thought the Coolness that proceeds from Fountains and Cascades will be more acceptable and refreshing to People of Quality.
the mean time, to find out a more agreeable Entertainment for the Winter-Season, the Opera of
Rinaldo
is filled with Thunder and Lightning, Illuminations, and Fireworks; which the Audience may look upon without catching Cold, and indeed without much Danger of being burnt; for there are several Engines filled with Water, and ready to play at a Minute's Warning, in case any such Accident should happen. However, as I have a very great Friendship for the Owner of this Theater, I hope that he has been wise enough to
insure
his House before he would let this Opera be acted in it.
