This work contains the heretofore unpublished memoirs of Brother Gilbert (a.k.a. Philip F. Cairnes), the Xaverian brother generally credited with steering the Babe to his first professional contract. Ruth was raised by the Xaverian Brothers, a Catholic religious order, at St. Mary's Industrial School from 1902 (when he was only 7) until 1914.

These reminiscences begin with Babe Ruth's departure from St. Mary's and concentrate on his early playing years. An historical introduction by the editor of these memoirs, Harry Rothgerber, details the history and relationship that existed between this organization of Catholic educators and the man who was to become the most influential baseball player and greatest slugger who ever lived. Brother John Joseph Sterne, the book's forewordist, recounts a St. Mary's band fundraising trip in which the band accompanied the Yankees through the American League cities at the end of the 1920 season. Several previously unpublished photos from the Xaverian Order complement the text.
