Subseries E. Journals contains a maritime journal where Patch wrote about trade, correspondence, travel, and conditions while at sea. It covers the period from 1804 to 1805, though the paper booklet is quite fragile and is likely missing pages. The second journal includes the following handwritten note on the inside of its front cover: "Commonplace Book, found in the John Patch house, Ipswich, Mass." It is a bound hardcover book containing myriad thoughts and reflections, the bulk of which are religious in nature.
