These records concern the operation of the post commissary at Fort Keogh. Included are outgoing and general correspondence (1876-1892); financial records (1878-1892), including abstracts, accounts, a ledger, payrolls, receipts, requisitions sales, subsistence stores lists, vouchers, and miscellany (1878-1893). Requisitions for supplies were directed to the Acting Commissary of Subsistence (A.C.S.) by various officers, and numbered post orders, both general and special for Forts Keogh, Buford, Snelling, Meade and Peck. [A volume of printed special post orders for Forts Keogh and Bliss (1887-1889) has been separated to the Library.]
