INGERSOLL & BRO., 43 Jewelers’ Court, New York, N. Y. * * * * * Have You Had My Free Lesson in Jiu-Jitsu? If you do not already know that Jiu-Jitsu is the most wonderful system of physical training and self-defense in the world to-day I invite you to write for my =FREE LESSON= and demonstrate this to your own satisfaction. [Illustration: YAE KICHI YABE, Late of the Ten-Shin Ryu School of Japan.] It is to the persistent practice of Jiu-Jitsu that the Japanese owe their courage and success in battle, their almost superhuman strength and power of endurance, their low death rate and their material progress. Surely a system of physical training which has done so much for the Island Nation will interest you. Jiu-Jitsu not only embodies the ideal principles of attaining perfect health and perfect physical development, but as a means of self-defense it is as potent at short range as the deadliest weapon. A knowledge of its self-preserving principles renders a man or woman impregnable to every form of vicious attack. Jealously Guarded Secrets Revealed. For over two thousand years the principles of Jiu-Jitsu have been religiously guarded. By an imperial edict the teaching of the system was forbidden outside of Japan. The friendly feeling, however, existing between Japan and the United States has been instrumental in releasing Jiu-Jitsu from its oath-bound secrecy, and I have been delegated to teach, without reserve, all the secrets of this ancient art to Americans. I have just written an intensely interesting book which explains and makes clear the principles of Jiu-Jitsu in a manner which will never be approached by any American writer. So long as the edition lasts this book, together with my first lesson in Jiu-Jitsu, will be sent free to interested persons. The lesson is fully illustrated and teaches one of the most effective methods known for disposing of a dangerous antagonist. If you desire to learn all the closely guarded secrets of this marvelous science send your name and address, and you will receive the book and specimen lesson by return mail, postage paid.
