Lastly, the easternmost Sahaptin are on the limits of the buffalo area; and as such are partially hunters, as well as common to the two sides of the Rocky Mountains. It is now convenient to return to the Pacific, and to follow from west to east the tribes that lie south of the area already described. THE YAKON. _Locality._--A strip of sea-coast between the Nsietshawus (Tsihaili) the Tlatskanai, the Kalapuya, the Umkwa, and the Saintskla. _Numbers._--About 700. KALAPUYA. _Locality._--Valley of the Upper Willamet. _Conterminous_ with the Watlala Tshinúks, the Molele, the Tlatskanai and Umkwa Athabaskans. _Numbers._--About 500. _Dialects._--1. Proper Kalapuya. 2. The Tuhwallatie or Follatie. 3. Yamkallie of Mr. Tolmie.--How far are these the same? MOLELE. _Locality._--Parts about Mount Hood and Mount Vancouver, south of the Columbia. _Conterminous_ with the Watlala Tshinúks, the Kalapuya, the Cayús, and the Lutuami. _Numbers._--"Reduced in 1841, by disease, to twenty souls. Probably now extinct."--_Hales._ _Divisions._--1. Molele. 2. Cayús(?) CAYÚS.(?) _Locality._--South bank of the Columbia, between the Molele and the Paduca Shoshonis. _Numbers._--About 500 good warriors, with extensive pasturage and large droves of horses, one chief having 2,000.--_Hales._ The note of interrogation denotes that the ethnological position of the Cayús is ambiguous. Mr. Hales makes them Molele, Dr. Scouler, Sahaptin. LUTUAMI. _Synonym._--Tlamatl or Clamet. _Locality._--Head-waters of the river Clamet, due south of the Molele, and conterminous with the Umkwa on the west, the Wihinast Shoshonis on the east, and the Palaiks and Shastis on the south. We are now approaching a series of tribes known by little more than their names. Beginning at the sea-coast to the south of the strip occupied by the Yakon, and in the immediate neighbourhood of the Umkwa country, we find in proceeding from west to east-- THE SAINTSKLA. _Locality._--South of the Yakon, between the Umkwa and the sea. THE TOTOTUNE. _Locality._--Sea-coast south of the Saintskla. THE KILLIWASHAT. _Locality._--Mouth of the Umkwa. THE TSALEL. _Locality._--Middle course of the Umkwa. THE KAUS. _Locality._--Between the river Umkwa and the river Clamet, or (ethnologically) between the Killiwashat and the Lutuami. SHASTI. _Locality._--South-west of the Lutuami. PALAIK. _Locality._--South-east of the Lutuami, and conterminous with the Shasti. The list of the tribes and families of the Oregon territory, is now, with one exception, complete, at least according to the present state of our knowledge; whilst the section that still stands over for notice, extends so far beyond it, and is in other respects so remarkable in its distribution, that it forms an ethnological break.
