Other volumes in this set include ISBN number(s): 0766126501. Volume two of a two volume set. (This description is for all volumes.) Mackey knew that very few men have the means, time, and the inclination for the purchase of numerous books, and for the close and attentive reading of them…to acquire a knowledge of all matters connected with the science, the philosophy, and the history of his Order. It was this thought that suggested to him that he should collect materials for a work which under one cover might help to enlighten his Brethren. This book is so absorbing you could sit and read it from cover to cover. It also serves as a handy reference guide for any Masonic question that may arise. Highly recommended.
