The lady also tells the names of cards dealt off from a thoroughly shuffled pack, spells out the word selected from a dictionary and gives its definition, reads a check held up against the blackboard, tells its amount, and the name of the one who drew it. There is no hesitation, no mistakes, and the answers and descriptions are given with the greatest rapidity. How is it done? The lady certainly cannot see, and the quickness with which the answers are given preclude the idea that Kellar conveys the information by such signals as walking in a certain way, tapping the blackboard, etc. The method is so simple that many of "the profession" consider it inartistic, but the public seems to like it. Every one who has attended a magical entertainment will have seen a narrow platform extending from the stage to the auditorium, by means of which the performer passes to and from the audience. This platform is known technically as a _run_ or _slip-stage_. With Sir Kellar this _run_ crosses the footlights and goes over a short distance on the stage, where it is slightly elevated, and is boxed in at the sides. A hole is cut in the stage, and through this hole, shielded from view by the _run_, sits Mr. Kellar's assistant. With the help of an ordinary opera-glass he can see everything that is written on the blackboard or is placed against it, and by a simple mechanical means, either of a speaking-tube leading under the stage from his hiding-place to the back of Mrs. Kellar's chair, or some similar arrangement, he can at once convey to her the needed information. If the cube root or square root of any number is asked for, he has merely to turn to some such work as _Haswell's Engineer's Companion_ to find the answer; should a word be selected from the dictionary, he refers to a second copy of the dictionary, which he has at hand, apply his mouth to the speaking-tube, and Mrs. Kellar answers: "The ninth word in the second column on the steen-hundredth page is _vicarious_, and the definition is, 'acting, performing, or suffering for another.'" Let us hope this word may never be selected, as it would be too suggestive. The reader will understand that there is scarcely a limit to what Mrs. Kellar (? or the assistant) can tell. As this trick is not practicable for the drawing-room, let me give one that my young friends will be able to accomplish. For the want of a better name I will call it "The Flying Watch." A watch is borrowed, and to prove that it is not obtained from a confederate, one of the audience is allowed to select paper of such color as he may prefer in which to have it wrapped, and another to choose the ribbon with which the package is to be tied. The packet is then placed in a handkerchief and handed to some one to hold. At word of command the watch leaves the handkerchief, and is found in the innermost box of a nest of three boxes, each of which is tied with tape and sealed.
