It is but a few years ago that jiu-jitsu was unknown to the Western world. Today the name is understood very generally, in English-speaking countries, to refer to that mysterious art of self-defense by which the Japanese prove antagonists whom it is impossible to defeat in physical encounter. To some extent, too, a little knowledge of this strange art has come to us. Within the next few years it is to be expected that jiu-jitsu will be as well understood by us as boxing is today.
