Sunday prayer meeting in the upper room of Joseph Smith's store; "Joseph not present," and "Brigham Young presided," apparently for the first time .
"B Young was called to the chair who addressed the meeting in a vary feeling manner & interesting to our minds, he reasoned clearly that we should follow our file leaders & our savior in all his law & commandments without asking any questions why they were so[--]He was followed by P. P. Pratt & others who expressed their minds freely[--]several sick were prayed for"
