"This is to certify that Mr. Harry Houdini, at the United States jail to-day, was stripped stark naked, thoroughly searched, and locked up in cell No. 2 of the south wing, the cell in which Charles J. Guiteau was confined from the date of his commitment, July 2, 1881, until the day on which he was executed, June 30, 1882. Mr. Houdini, in about 2 minutes, managed to escape from that cell, and then broke into the cell in which his clothing was locked up. He then proceeded to release from their cells all the prisoners on the ground floor. There was positively no chance for any collusion or confederacy. Mr. Houdini accomplished all of the above-mentioned feats, in addition to putting on all his clothing, in 21 minutes. "J. H. HARRIS. "Warden United States Jail, D. C." * * * * * Major Sylvester yesterday prepared for Houdini the following statement: TO WHOM IT MAY CONCERN: No individual should be disinclined to profit by the abilities displayed by others, and, in order that defective means of restraint might be discovered in the holding of prisoners in this jurisdiction, and with a view to remedying any insecurity which might exist, Mr. Houdini, the expert man with locks, was permitted to examine a modern cell lock and attachment, and then placed in an entirely different cell from the one he examined. He was searched, and in a nude condition placed behind the bars, and, as supposed, secured. This was in the presence of the Engineer Officer of the District of Columbia, myself, and several officers. In 26 minutes he emerged from the cell and corridor fully attired. "The experiment was a very valuable one in that the department has been instructed as to the adoption of further security which will protect any lock from being opened or interfered with. The act was interesting and profitable, and worthy of study. "Mr. Houdini impressed his audience as a gentleman and an artist who does not profess to do the impossible. "RICHARD SYLVESTER, "Major and Superintendent." * * * * * SOME OF THE GREAT FEATS ACCOMPLISHED BY HOUDINI. Broke out of the Siberian Prison Van in Moscow, Russia, in May, 1903.
