It appears that to this lock was fitted a steel barb which, if a certain tumbler was overlifted in the act of picking or otherwise, was projected against the hand of the operator by a spring. I have seen such a lock as this in the collection of Hobbs, Hart & Co., London, who have had it in their possession many years. In every respect it answers the description of the invention claimed by Robert-Houdin as his own. Chapter VII. of "Secrets of Stage Conjuring" is devoted to Robert-Houdin's very incorrect explanation of the famous Indian Basket Trick. Even his own translator, Professor Hoffmann, takes issue with Robert-Houdin, as will be seen by reading his foot-note on page 104: "We will not venture to question the fact vouched for by so high an authority as Robert-Houdin, that the Indian Basket Trick may sometimes be performed after the manner above described, but we doubt very much whether such is the usual or customary method." [Illustration: A Ramo Samee handbill, featuring his stone-swallowing act.

From the Harry Houdini Collection.] Robert-Houdin states that the child is placed in the basket, and the Indian fastens down the lid with leather straps. To facilitate this operation, he rests his knees against the basket, and the bottom of the latter thus being turned toward the audience, the boy slips out through a cunningly contrived trap and quickly conceals himself under the robe of the magician, whose attitude favors this concealment. As the basket trick is the Hindoo magician's most wonderful offering, a truthful account of his methods of performing the same may be interesting. In the first place, Robert-Houdin's explanation is impossible and unreasonable because the Hindoo magician does not wear flowing robes in which the child could be concealed. Every Hindoo performer I have ever seen wore short trousers and was barefooted. The correct method of performing the trick, which has been handed down through generations of Hindoos, is as follows: The boy subject is placed in a net in which he is firmly tied, after having had his big toes and thumbs fastened down with bandages. Then, with many a grunt and a groan, he is lifted into the basket. The subject, however, pretends that the basket is too small, so he is really seated on one side and keeps his back in the air. This is done to give the appearance eventually that it was impossible for him to crouch down or around the basket. The lid of the basket is now placed on his back, and a large sheet is thrown over the entire apparatus, which conceals from the audience every movement made by the subject.
