Is the litle Cif the secret society which Invented, Improved and practices a ujethod almost the direct reverse of wrestling, which enables a loan of average size and strength to break the arm, leg oreven toe nelt; k of a giant with one twist.The member* of the Embok Kwalguard their secret* Jealously, and It i» raid that O’Brien Is the only foreigner to whom they revealed the methods of their art. He wan h member of thepolice force at Nagasaki for ten years and wus Initiated by Home of the nativeofficer*.He 1m of medium height and ordinary strength, and when he returned twoyeurs ago to America and offered to make any man who stood up to him cry ‘‘Quit!’' In two second* ho waslaughed at and given plenty of materia! to work on.Hut he made good his promise with every pugilist, wrestler and strong man he met and has since then beenkept busy giving lesson*. The trick consist* of bending the joints of your adversary’s arm or leg In the direction opposite to that Intended by nature.The holds are simple nml may be quickly gained. Once gained, if the other man does not cry mercy hisbones may be literally crushed by a» ivery easy twist.Every one of the holds,” said O’Brien In a lecture ou the subject, “is foul from our wrestling standpoint, buteach is to be used only in case of danger, when you don’t care what means you use to escape. You don’t need to be particularly careful of fouls with a footpud or with an enemy witha gun. You want to put it quickly out of his power to injure you; that’s all.“The reason that the secrets of theJlu Jltau have been so Jealously guarded Is because they must not fall Into the hands of the unscrupulous. There is one hold In It that will kill a manand not leave a mark of any kind onhim.There are about 2b0 grips In the system, but a thorough knowledge of the main half dozen will give a man till the protection lie needs As President Housevelt Is already acrack boxer, u dead shot mid a good wrestler, he will, when he masters theJapauese science, be a very uncomfortable person to tamper with. His strength Is exceptional and his nerve undoubted, and there is little fear thatany one will ever try to molest him.
