The definite recollection which the Kiowa have of these tribes shows that they must have been very intimate with them in former times, especially with the Arikara, whom they call _K'át'á_, "biters," designating them in the sign language by a twisting motion of the closed right band, with thumb extended, in front of the month, the allusion being to gnawing corn from a cob. In the north the sign is sometimes made with both hands, the right working against the left, the allusion then being to shelling corn. The Arikara are preeminently distinguished among the northern tribes as the corn-planting Indians, and are usually designated in pictographs by the figure of a man with an ear of corn. It is probable that they taught agriculture to the Mandan and Hidatsa. The Kiowa further identify the K'at'a as being called _Paläni_ by the Dakota and as speaking a language like that of the Pawnee. Stumbling-bear claims to have met and talked with some of them on a former visit to Washington. They have more to say of the Arikara than of the others, probably because then, as now, they were the largest of the three tribes, and also, as the Kiowa themselves say, because the Arikara lived nearest, being probably located then, as at a later period, on Ree or Grand river, in South Dakota, which is called by their name in the various Indian languages. They describe the three tribes as living on the Missouri (_Tsosâ P'a_) river, in earth-covered grass houses (really log houses, filled in between the logs with grass and covered with earth), and cultivating corn and tobacco, which they traded to the Kiowa. One of the principal divisions of the Kiowa tribe, and the one to which the great Dohásän and several other prominent chiefs belonged, is the K`at'a or Arikara band, so called, the Kiowa state, on account of their special intimacy with the Arikara in the old times, and not because of Arikara descent. The name of the band must have originated, of course, subsequently to the first acquaintance of the two tribes.
