[George Q. Cannon]
... During his remarks Brother Snow said that the Lord would reveal unto the Twelve in case of a dissolution of the First Presidency the men He wished to preside over His kingdom here on earth just as He had done from the beginning. He felt that in case of a death occurring in the First Presidency the Lord would very soon call men to that position. These remarks of Brother Snow called forth the following from President Woodruff: "I want to say one thing in connection with what Brother Snow has said. I want to give counsel to my brethren the counselors, to these Twelve Apostles and to these men of Israel, that when ever I pass away do not let this Church stand without a Presidency one year nor ten months, but go to and organize the Presidency and keep it, and it should be kept in this Church and kingdom until the coming of the Son of Man."
[Lorenzo Snow gave his speech as the president and senior member of the Quorum of Twelve. He would succeed Wilford Woodruff as president of the church five years later, just eleven days after Woodruff's death. Previous successions took years.]
