Miscellaneous original manuscripts, 1787-1883. The earliest piece (1787) pertains to the provisioning of Harmar's troops. Most of the papers during Hinde's lifetime are legal in content and relate to his involvement in land transactions, his attempts to secure inheritance for his first wife from the estate of her father, and to Hinde's business of searching out and pursuing land claims for Revolutionary War veterans.

From 1824 to 1830 Hinde focused his thought on the plight of the American Indians. This interest is documented by letters (1824) to James Barbour and John McLean and one from John C. Calhoun; a petition to Congress detailing the proposal by John C. Symmes and Hinde that they establish a government-sponsored trading company among the Indians of the far Northwest along the Columbia River with provisions for schools, churches, and transportation for tribes en route and land bounties for each white man who married an Indian; and other articles on Hinde's schemes for Indian territorial government in the West.

Several items of interest on other topics may also be cited: a letter (1808) by Edward Tiffin on the Embargo laws and United States policy toward England; a certificate (1809) written and signed by Governor John Tyler of Virginia; a letter (1813) on Methodist affairs by William McKendree; medicinal formulas (1813); and a letter (1820) by Dr. Thomas Hinde. Also included are letters (1814) on military matters by Charles S. Todd; a military bounty land warrant (1819) signed by President James Monroe; a letter (1826, badly mutilated) on publications to Lorenzo Dow; a letter (1837) by John Mason Peck with a prospectus for his proposed history of Illinois; and a letter (1839) addressed to Governor David Wallace of Indiana on internal improvement projects on the Wabash River. Among Hinde's other correspondents were Philip Doddridge, Andrew Ellison, John Law, William Lytle, Benjamin Temple, and David Zeigler.

After Hinde's death, a group of letters and notes, 1846-1883, concerns Draper's acquisition of Hinde's papers and his troubled relations with the heirs over his retention and use of them.
