THE ENCHANTED TELESCOPE.
In this variation of the Nostradamus Trick, a telescope-tube is mounted, instead of the false mirror, on a stand on a table. It has a plane mirror set in it at an angle of forty-five degrees over the stand, which is hollow and communicating with a drawer of the table, opening into the next room, with a second plane mirror, to reflect any person therein, up to the tube reflector.
The inner room should be dark, so that, when the light is cut off, the figure will vanish.
