I am organizing my martial arts books and found "Jiu-Jitsu the Japanese Method of Attack and Self-Defense" by Capt. H. H. Skinner dated 1904. On the title page reads "A Comprehensive and Copiously Illustrated Treatise on The Wonderful Japanese Method of Attach and Self-Defense" As a traditional martial artist, I find this book fascinating. The techniques described in the book are the same ones we use today. Good techniques stand the test of time.
However, there are some unique scenarios described in 1904. There is a segment on how sometimes it is necessary to arrest a policeman or as they put it "a copper". The technique is a disarm of his club from behind.
