"The Ancient Arch in the Black Forest," is a sort of house of call for witches, and it being seen during their merry-making, or holiday, is rendered more picturesque by the _Devil's_ "Ha, ha!" The hospitable _Zabaren_ entertains hundreds of witches, of all sorts and sizes, who dance all manner of country-dances, and sing a series of songs and choruses, in which the "Ha! ha!" is again conspicuously introduced. It seems that German witches not only ride upon brooms, but sweep with them; and a company of supernatural Jack Rags perform sundry gyrations peculiarly interesting to housemaids. After about an hour's dancing, the witches being naturally "blown," are just in cue for leaving off with an airy dance called the "witches' whirlwind." This episode over, the plot goes on. _Ottocar_ accuses _Ida_ of infidelity with _Wilhelm_ to the duke; she, in explanation, fulfils the presentiment we had some delicacy in hinting too soon--that she is the wife of the man who was killed in the prologue; _Rudolph_ having married her in ignorance of that fact, and by a coincidence which, though intensely melo-dramatic, every body foresees who has ever been three times to the Adelphi theatre. To describe the last scene would be the height of presumption in PUNCH. Nobody but "Satan" Montgomery, or the Adelphi play-bill, is equal to the task. We quote, as preferable, the latter authority:--"Grand inauguration of _Wilhelm_, the rightful heir. CORAL CAVES and CRYSTAL STREAMS: these are actually obtained by a HYDRO-SCENIC EFFECT! As the usual area devoted to illusion becomes a reality!" Besides all this, which simply means "real water," there is a _Neptune_ in a car drawn by three sea or ichthyological horses, having fins and web feet. There is a devil that is seen through the whole piece, because he is supposed to be invisible (cleverly played by Mr. Wieland), and who having dived into the water, is fished out of it, and sent flying into the flies. This sending a devil upward, is a new way of [Illustration: TAKING OFF THE DARK GENTLEMAN.] Being dripping wet, the demon in his ascent seriously incommodes _Neptune_; who, not being used to the water, looks about in great distress, evidently for an umbrella. After several glares of several coloured fires, the curtain falls.
