The collection consists of Morrow's original autograph draft of his expedition journal (approx. 213 pp.), over 100 pp. of manuscript lists and receipts for seeds and agricultural items, 19 manuscript letters or notes, one photograph of Morrow, and various additional documents, all inscribed or completed in manuscript. Much of this relates to the Perry Expedition, documenting, supplementing, and corroborating the published journal and papers edited by Allan B. Cole (A Scientist with Perry in Japan: The Journal of Sr. James Morrow, 1947) -- themselves a supplement to Perry's Narrative of the Expedition of the American Squadron to the China Seas and Japan . . . (1856). In addition to the expedition materials, the collection includes a number of documents of biographical interest about Morrow, dating from his college years in the 1840s to the year of his death in 1865 at the age of forty-five.
