[William Clayton Journal] President Joseph instructed S[amue]l James in the order of the Holy Priesthood [Plural Marriage] ...I had some conversation with Brother [Newel] Whitney and have learned that Farrs family are conspiring with Walkers boys and girls and they with E[mma] to accomplish my downfall. I find they are my secret enemies but I fear them not for God who knows the secrets of all hearts knows mine also. I told M[argaret] [his plural wife] of this and ascertained that she had acknowledged to A[aron] [her former fiance] that I had slept with her and if it never had been done (our union) it should not be. This of course has given him a plea and a weapon against me.
