[President Heber J. Grant]
At ten o'clock attended the regular weekly Council meeting of the Presidency and Twelve. I blessed Brother Clark and ordained him an Apostle and set him apart as one of the Council of the Twelve Apostles. I then blessed Brother McKay and set him apart to be my second counselor, and ordained Alonzo A. Hinckley an Apostle and set him apart as a member of the Council of the Twelve Apostles. I first gave an extended talk to Brother Hinckley as to his duties in coming into the Council of the Presidency and the Twelve. He replied, accepting all of the obligations.
