4. The chart of Mato Sapa, Black-Bear. He was a Minneconjou warrior, residing in 1868 and 1869 on the Cheyenne Agency Reservation, on the Missouri River, near Fort Sully, Dakota, near the mouth of the Cheyenne River. In order to please Lieut. O. D. Ladley, Twenty-second United States Infantry, who was in charge of the reservation, he drew or copied on a piece of cotton cloth what he called, through the interpreter, the History of the Minneconjous, and also gave through the same interpreter the key or translation to the figures. Lieutenant Ladley loaned them to an ex-army friend in Washington, who brought them to the notice of the present writer. This copy is on a smaller scale than that of Lone-Dog, being a flat and elongated spiral, 2 feet 6 inches by 1 foot 6 inches. The spiral reads from right to left. This chart, which begins as does that of Lone-Dog, ends with the years 1868-’69. The present writer has had conversation and correspondence concerning other copies and other translated interpretations of what may be called for convenience and with some right, on account of priority in publication, the Lone-Dog system of winter counts. But it also was discovered that there were other systems in which the same pictographic method was adopted by the Dakotas. An account of the most important of these, viz.: the charts of Baptiste or Battiste Good, American-Horse, Cloud-Shield, and White-cow-killer has been communicated by Dr. William H. Corbusier, assistant surgeon, United States Army, and is presented _infra_, page 127, under the title of The Corbusier Winter Counts.
