To Thomas Jefferson from Henry Dearborn, 23 December 1807
Decemr. 23d. 1807
Sir,
When Capt. Gains was here in July last, I requested him to explore the Country between the Tennessee River, both above & below the mussle shoals, and the boatable waters of the Tombigby and to measure the distance, and report the result to this department, I have not yet received the report, but I think it probable it will soon be received. Yours respectfully
H Dearborn
