Herr Alexander had arrived in New York almost penniless, after a disastrous tour of other American cities. He tried to hire Niblo's Garden, but was informed that the auditorium was never opened in winter. Through the intercession of Mrs. Niblo, however, he finally secured it at a rental of twenty dollars per night. He opened to a small house and for three nights did not even pay expenses, but the fourth night witnessed a change in his fortunes and for three months he played literally to standing room. Then because he had no new tricks to offer, and his pride forbade his presenting his old répertoire until receipts grew lighter, he closed his New York season. While playing in Saratoga, Alexander was approached by the late P. T. Barnum, who was accompanied by Gen. Tom Thumb. Alexander declined Mr. Barnum's offer because he thought to join the Barnum staff of entertainers would injure his professional rating. Barnum's admission fee was 25 cents, while Alexander charged 50 cents and $1. About this time the fame of Alexander attracted the attention of no less a personage than S. F. B. Morse, of telegraphic fame; and Alexander had on his programme one trick which mystified Morse, who honestly believed that the conjurer had discovered some new law of nature that might be of service to scientists. [Illustration: Alexander Heimburger presenting the suspension trick during his engagement in Brazil.

Some employ a thread and hook, causing the clapper to strike by pulling the thread which runs through an innocent-looking ribbon on which the bell hangs. Others use an electric magnet. Herr Alexander placed his bell on top of a fancy case which he could set anywhere, and the bell would ring at command. The secret was a small bird, trained to jump from one rung of a tiny ladder to another, at word of command or the waving of a stick or wand which the bird could see from its point of imprisonment. Every time that it jumped from one rung to another, it would pull down a step which was so arranged that by the smallest overweight it would release a catch, which in turn would throw the hammer against the glass. When the bird stepped off, the hammer would again come back to its original position and be ready for the second blow. This bird he bought from a street fortune-teller, who had trained it to go up different steps of a ladder and select envelopes containing variously printed fortunes.
