After examination of all the charts it is obvious that the design is not narrative, that the noting of events is being subordinated to the marking of the years by them, and that the pictographic serial arrangements of sometimes trivial though generally notorious incidents having been selected with special adaptation for use as a calendar. That in a few instances small personal events, such as the birth of the recorder or the death of members of his family, are set forth, may be regarded as interpolations in or unauthorized additions to the charts. If they had exhibited a complete national or tribal history for the years embraced in them, their discovery would have been in some respects more valuable, but they are interesting to anthropologists because they show an attempt before unsuspected among the northern tribes of American Indians to form a system of chronology. While, as before mentioned, it is not now necessary to recapitulate the large amount of matter before published concerning the Winter Counts of the Dakota, it has been decided to present in an abbreviated form the characters and interpretations of the Lone-Dog chart as being the system which was first discovered, and the publication of which occasioned the discovery of all the other charts mentioned. The Winter Count of Battiste Good has not hitherto been published, and it possesses special importance and interest apart from its chronology, for which reason it is inserted in the present paper, see infra. The several charts of The-Flame, The-Swan, American-Horse, and Cloud-Shield, published in the Fourth Annual Report of the Bureau of Ethnology, are omitted, but selections from all of them are presented under the headings of Ideography, Tribal and Personal Designations, Religion, Customs, History, Biography, Conventionalizing, Comparison, and in short are interspersed through the present paper where they appropriately belong. The reader of the Lone-Dog and Battiste Good charts may find it convenient to note the following brief account of the tribal names frequently mentioned: The great linguistic stock or family which embraces not only the Sioux or Dakota proper, but the Missouri, Omaha, Ponka, Osage, Kansa, Oto, Assinaboin, Gros Ventre or Minnitari, Crow, Iowa, Mandan, and some others, has been frequently styled the Dakota family. Maj. J. W. Powell, the Director of the Bureau of Ethnology, from consideration of priority, has lately adopted the name Siouan for the family, and for the grand division of it popularly called Sioux has used the term Dakota, which the people claim for themselves.
