Audiobook: Seven and Nine years Among the Camanches and Apaches: An Autobiography

Best described as a fictional autobiography, Clark Johnson authored the following adventure to promote the sale of his brand of Homeopathic elixir or commonly known as "Snake Oil".

Using the fictitious hero's, Edwin Eastman and his wife, Mr. Johnson penned the hair raising tale of a pioneer family wandering off the wagon trail and straight into the heart of hostile Indian country. All but he and his wife were struck down in the ensuing battle. Captured, Edwin and Mrs. Eastman survived only to be imprisoned by the Comanche Nation with Mrs. Eastman eventually being sold to the Apache's. Edwin, lives among the Comanches for seven long and torturous years.

Demonstrating courage and tenacity, Edwin was taken in by the great medicine Chief Watkometkla. Allowed to live, Mr. Eastman gained valuable knowledge in the art of Homeopathic medicine and the Comanche way of life.

Through the adventure of his captivity, Mr. Johnson describes Edwin's life in detail. The Native American culture. The rise of new leaders. The preparation for war. Scenes of great battles. Habits, lifestyle and so on.

Mr. Johnson's knowledge of these various traits were unfortunately 'borrowed' from a previous novel published in 1854 and written by T.D. Bonner. The Life and Adventures of James P. Beckwourth.
