Series V. Political and Business Papers reflects Browne's interests in national and New England politics, non-California mining ventures, savings banks, ship timber bending, and maritime law. The correspondence contains fascinating accounts of Washington and New England politics during the presidency of John Tyler. Included is news of the cabinet's resignation, reorganization of the Navy, the popularity of Henry Clay (1777-1852), and the Tyler re-nomination convention. Brownes' interest in maritime law is documented in two 1858 cases for which he acted as an attorney: the collision of the US Release and Brig Leontine, and the impressment of an American seaman off the Salem brigantine Rockingham by a French vessel. The miscellaneous papers contain deeds for land in Maine, incorporation papers of the Essex County Institute for Trusts and Deposits, petitioners for the Salem Five Cents Savings Bank, and a list of delegates to the 1850 Salem Representative Convention.
