The Calvin A. and Albert H. Irish diaries consist of 2 volumes. Calvin A. Irish kept a diary from January 1865, during the end of his service in the Union Army, until May 1866. His son, Albert H. Irish, also wrote a diary in 1885.
For his diary, Calvin used a printed almanac entitled Vermont Directory and Commercial Almanac for 1865. The entries are mostly short and detail his daily activities and experiences, including the distance he marched, the weather, letters that he sent or received, and work that he accomplished. The small volume was also Calvin's financial ledger.
Calvin's son Albert also wrote daily records in an almanac entitled The American Diary 1885. The first 2 manuscript pages are comprised of a few verses and adages. Albert's entries are short and include information about the weather, school, chores, odd jobs, and visits of his friends and neighbors. The almanac also contains a short cash-management ledger and brief descriptions of the Irish family's cows.
