[Charles W. Penrose]
... I was blessed and set apart by Presidents W[ilford]. Woodruff Geo[rge] Q. Cannon and Apostle Brigham Young [Jr.] as an Assistant Historian for the Church, Bro[ther] Cannon being mouth. The spirit of revelation and prophecy, with discrimination and judgment, power to avoid bias and to select and write to the acceptance of God and the Church authorities etc etc were sealed by the authority of the Holy Priesthood in the name of Jesus Christ.
