_Ä´yä´daldä Sai_, "Timber-hill winter," so-called on account of the famous treaty made this winter with the confederated tribes on Medicine-lodge creek, Kansas, known to the Kiowa as "_Ä´yä´daldä P'a_, Timber-hill river." The picture on the Set-t'an calendar is highly suggestive. It represents a white man, who appears to be a soldier, grasping the hand of an Indian, the locality being shown by the figure of a tree-covered hill above the winter-mark. The Anko calendar has no reference to this treaty, which is the leading event in Kiowa history of the last thirty years, but records instead a minor occurrence, the killing by the Kiowa of a Navaho, indicated below the winter mark by the figure of a man with his hair bunched in Navaho fashion, wearing the characteristic black leggings and moccasins and carrying a quiver. He was killed near _Gúădal Dóhá_, on the upper South Canadian, by a party under White-horse, of which Anko was a member. On examining the body of the dead man they found that he had no ears, having probably been so born. For this reason the winter is sometimes known as _T'á-bódal Ehótal-de Sai_, "Winter that Spoiled-ear was killed." Several parties went against the Navaho on the Pecos this year (that tribe being still at the Bosque Redondo), particularly a large expedition, including nearly all the Comanche and about half of the Kiowa and Apache, which started immediately after the sun dance, defeated the Navaho in an important engagement, and returned in time for the treaty.
