1778 June 3 (Wednesday). I rode on an Horse of Mr. Tainters to the Fast at Grafton. It was occasioned by Rev. Grosvenor’s Hoarseness, so that he has not preached these two Years. Dr. Hall, Mr. Fish and Mr. Sumner came. Dr. Hall began the Solemnity with Prayer. Mr. Fish preached a.m. on Isa. 31.9. An excellent good and pertinent Sermon. May God forgive my ill Frame and bless it to me and to all Concerned! P.M. Mr. Sumner prayed and I preached on 2 Cor. 4.1 and read Several more verses. Which may God bless to us to our highest Benefit! Mr. Farrar who preaches on the Sabbath here, was among us. I returned home at Eve. Mrs. Cotton left us about 4 p.m. and went to Hopkinton.
