SIOUAN FAMILY.
The Siouan family includes the Dakota, Assiniboin, Omaha, Ponka, Osage, Kansa, Kwapa, Iowa, Oto, Missouri, Winnebago, Mandan, Hidatsa, Crow, Tutelo, Biloxi, Catawba, and other Indians. The Sapona, who are now extinct, probably belonged to this family.
The author was missionary to the Ponka Indians, in what is now part of Nebraska, from 1871 to 1873. Since 1878 he has acquired native texts and other information from the Omaha, Ponka, Osage, Kansa, Winnebago, Iowa, Oto, Missouri, and Dakota.
In seeking information respecting the ancient beliefs of the Indians the author has always found it expedient to question the Indian when no interpreter was present.
