This collection contains a letter and a copy book of Thomas Moore, agent for the ship Nimrod. The 4-page letter (1821) tells of Moore's earlier business with Howland & Co. and about the political situation in South America. The letter makes it clear that Moore acted as his own copyist and that the letter book was his personal record. The letter book commences June 28, 1822, as agent Moore writes his owners, G.G. & S. Howland, from Java Head, summarizing his voyage to date. He reaches Canton in July and writes extensively of conditions there. He also lists goods taken onboard, which he plans to sell in the South American market. Later he transacts other business on the Howlands' behalf, the report of which takes up another 35 letters, finally closing out the accounts in April, 1824.
