Folger was involved with the Cerneau Rite, and his work was, and still is, considered controversial. Twice he was expelled from Freemasonry by the Grand Lodge of New York, and at various times had his hand in at least six clandestine Scottish Rite Supreme Councils—yet he was reinstated and died a Mason in good standing. This volume is invaluable in understanding the evolution of the degrees of the Scottish Rite before and after Pike.
