Sunday prayer circle meeting at noon in the upper "assembly room" of Joseph Smith's store where "all [were] present except Hyrum & his wife," and Emma Smith attended even though she "had been unwell during the night." Instead of ordinances, this was a political meeting: "The fore part of the day was taken up on the Appeal to the Green Mountain Boys. It was read by W. W. Phelps & [was] consecrated & dedicated unto God by the quorum."
[I believe this is the first time women participated in priesthood quorum decision making/ business.]
