Letters in relation to the Treaty Department of War, Off: Ind: Affaires, 14th August 1827. Gentlemen, I have the honor, by direction of the Secretary of War, to acknowledge the receipt of your letter of the 8th instant, enclosing a com- munication from Mess. Parsons and Hicks, rela- tive to the proceedings at the late treaty with the Seneca Indians in New York. The treaty referred to was held with the appro- bation of the Department, and Judge Forward was duly authorized to attend it, on the part of the Government, and the Secretary directs me to enclose to you for your information, the enclosed copies of letters received from Judge Forward and Capt. Parrish, the sub Indian agent, which, it is believed, contain a correct statement of the proceedings at said treaty, and afford a satis- factory vindication of their fairness. I have the honor to be, Your Mo. Obd. Serv. Sam. S. Hamilton. To Mess. P. E. Thomas Tho. Ellicott Balt.
