the river; while numerous bands on Sauvie Island and about the mouth of the Willamette were known by the collective name of Multnomahs. The Clackamas tribe lived in the Clackamas Valley and about the falls of the Willamette. In all, some 36 tribes of the Chinookan family occupied the south shore of the Columbia, and as many others dwelt near the north bank.
The Athapascans occupied two widely separated regions. On the Clatskanie and upper Nehalem Rivers lived the Tlatskanai, a warlike tribe. It is said that the early Hudson's Bay Company trappers did not dare to traverse their lands in a group of fewer than 60 armed men. In southwestern Oregon dwelt the other Athapascans—the Tututni, the Upper Coquilles, the Chastacostas, and the Chetcoes. Also in the southwestern region were the Umpquas and the Siuslaws, who together form a separate family.
The Salishan family, although more numerous north of the Columbia, was represented south of that river by the Tillamooks and the Siletz. The Yakonians, consisting of the Yaquina and the Alseas, lived on the two bays thus named; and on Coos Bay and the lower Coquille dwelt the three tribes of the small Kusan family.
One of the most important families was the Kalapooyan. This numerous people occupied the whole of the Willamette Valley above the falls, practiced flattening of the head, and lived on game and roots. A dozen tribes of this family inhabited the Willamette region at the coming of the white man. The Atfalati or Tualati, numbering more than 30 bands, occupied the beautiful and fertile Tualatin Valley. Other tribes of this group were the Yamhills, the Chemeketas, and the Santiams.
The southern part of Oregon was occupied by divisions of three families: the powerful Klamath and Modoc tribes of the Lutuamians or Sahaptians, the Takelmans of the upper Rogue River, and two "spillovers" from California—the Shastas and Karoks of the Hokan family.
The upper Columbia River country was the home of other Sahaptians. The greater part of this family lived in eastern Washington and the Lewis River district of Idaho; but four tribes, the Willewah branch of the Nez Perces, the Umatillahs, the Teninos of the Deschutes River, and the Tyighs of the Tygh Valley, inhabited the uplands of eastern Oregon. The Waiilatpuan branch was represented by the powerful Cayuse or "horse" Indians, dwelling on the headwaters of the Umatilla, the Walla Walla, and the Grande Ronde Rivers. A small offshoot of this branch had in times past wandered over the Cascades into western
