Book excerpt: This handbook of American Judo is a thorough study in the methods and techniques of hand-fighting. It is based upon the classic jiu-jitsu but incorporates most recent improvements in the scientific development of modes of personal combat. The first purpose of this book is to develop a technique of disabling and, if necessary, seriously injuring an opponent. The second purpose is to give the reader adequate skill and knowledge in defending himself against an assailant. Includes 200 photographs illustrating jiu-jitsu, wrestling, foot-fighting and police tactics.
