On the five rolls of this microfilm publication, M1791, are reproduced schedules of the special census of Indians enumerated in 1880. Section 8 of the census act of March 3, 1879 (20 Stat. 475), authorized the Superintendent of the Census to "employ special agents or other means to make an enumeration of all Indians not taxed, within the jurisdiction of the United States, with such information as to their condition as may be obtainable." A special enumeration therefore was taken of Indians living near military reservations.
