The well-known company of rats at the Park Theatre understand, it is said, their cue perfectly. It is worth the price of admission to see their performance. By long training they know precisely the time when the curtain rises, and the exact degree in which the audience is spellbound by what is going on. At the sound of the bell they sally out; scouring the pit for chance peanuts and orange-peel. When, by the rhyming couplets, they are made aware that the curtain is about to fall, they disappear – through respect for the moving heels of the audience. Their temerity is regulated by the intensity of the performers. A profitable engagement might be made, we think, with “the celebrated Dog Billy.”
