1771 September 12 (Thursday). John to Concord, designing to Boston. Mr. Sumner dined here. Had a Catechetical Exercise, to 25 Young Women. N.B. we finished the Catechism. My Exercise was taken from my Exposition on the Lords prayer, No. 103, 104, with some additions. To make way for which, I was obliged to omitt some Things also. I acquainted young women with its being 30 years last June Since I began the Exercises: and that seeing Such a Number of ‘em were willing to attend, I Should be encouraged, probably, to appoint another before Winter: but that if I did, they must be sure to attend upon it, lest I should proceed no further.
