Interleaved almanac, 1746

The 1746 diary is interleaved in Poor Richard's, An almanack for the year of Christ 1746. The thin paper-covered book holds brief notes about Holyoke’s daily life, written on blank pages bound with the almanac. More consistently filled out, the diary continues information about Holyoke’s senior year at Harvard, and his appointment as a schoolteacher in Lexington, Massachusetts. The September and October entries reference local military movements of King George’s War. The diary includes regular entries on individuals who preached and lectured at Harvard. Holyoke mentions an earthquake in February, and in March he notes that Harvard Professor John Winthrop "had a lecture: Solving ye Aurora Bor[ealis]."
