[President Heber J. Grant]
After the funeral today [of Counselor Anthony Ivins] Brother Clark called and I told him I thought we ought to decide on a counselor and asked for his suggestions. He said, 'I think anyone whom you want will suit me.'
I said, 'My mind had rested upon Brother McKay.'
He said, 'I am very glad; he is the man that I had thought of and would like.' He said, 'I started with the head of the Quorum, and when I got to brother McKay, I did not have any desire to go further.'
I sent for Brother McKay and notified him of our choice. He was very much surprised and pledged his absolute loyalty, and I felt sure he would do all in his power to aid in fulfilling the duties of the Presidency of the Church.
