While, as before said, some tribes give names to children from considerations of birth and kinship according to a fixed rule, others confer them after solemn deliberation. They are not necessarily permanent. A diminutive form is frequently bestowed by the affection of the parent. On initiation a warrior always assumes or receives a name. Until this is established he is liable to change his name after every fight or hunt. He will generally only acknowledge the name he has himself assumed, perhaps from a dream or vision, though he may be habitually called by an entirely different name. From that reason the same man is sometimes known under several different epithets. Personal peculiarity, deformity, or accident is sure to fix a name, against which it is vain to struggle. Girls do not habitually change names bestowed in their childhood. It may also be remarked that the same precise name is often given to different individuals in the same tribe, but not so frequently in the same band, whereby the inconvenience would be increased. For this reason it is often necessary to specify the band, sometimes also the father. For instance, when the writer asked an Indian who Black-Stone, a chief mentioned in the Dakota winter counts, was, the Indian asked, first, what tribe was he; then, what band; then, who was his father; and, except in the case of very noted persons, the identity is not proved without an answer to these questions. A striking instance of this plurality of names among the Dakotas was connected with the name Sitting-Bull, belonging to the leader of the hostile band, while one of that name was almost equally noted as being the head soldier of the friendly Dakotas at Red-Cloud Agency. The present writer also found a number of Dakotas named Lone-Dog when in search of the recorder of the winter count above explained. The case may be illustrated by christian names among civilized people. At the time when a former President of the United States was the leading topic of conversation, nearly any one being asked who bore the name of Ulysses would be able to refer to General Grant, but few other christian names would convey any recognized identity. Indeed, the surname may be added and multiplicity with confusion still remain. Very few men have names so peculiar as not to find them with exact literation in the directories of the large cities.
