Reservation Plan (Continued) Willamette Valley and Its environs were an Important source of furs and supplies, particularly venison, for the fur traders along the Columbia. Fur trading parties, first of the Northwest Fur Company, and after 1821, of the Hudson's Bay Company, visited the region to trade and to trap, and to use the valley as a route to the south. These men found the climate and resources of the valley attractive. French Canadian employees and former employees of the fur companies began to settle above the falls of the Willamette. Soon there were small farms with herds of horses, cattle, and sheep. Many of these men married Indian wives and established close ties to Indian communities. The relations between the early traders and the Indians was for the most part friendly, although there was some conflict with groups on the southern perimeters of the Willamette Valley. In 1818 a Northwest Company party killed fourteen Indians In the Umpqua Valley and In 1828 eleven . members of a Independent American fur trapping party were killed In an altercation on the lower Umpqua. Whatever the reaction of Indians to Incursions of newcomers In the Willamette Valley, they could muster little resistance after severe epidemics of introduced diseases swept the region between 1830 and 1832. Fur traders were followed by missionaries and others. In 1834 Jason Lee established a mission in the mid-Willamette Valley. In the following years, more and more travellers were using the valley as a route between California and the Northwest. By the 1840's there were settlements along the lower Columbia and up the Willamette to the falls. After 1845, when 3,000 settlers entered Oregon, these newcomers began to establish themselves In farming communities upstream In prime locations through the Willamette Valley. Some Indians also began to farm. The gold rush to California in 1849 temporarily slowed European settlement In and development of the region. However, by the mld- 1850s, large numbers of settlers entered the valley and taken claim to much of the prime land. Prospectors working north from California searched for gold In the peripheral mountain and hill country and entered the lands of Indian groups that previously had been spared the heaviest pressures of the contact period. By the 1850s there was Increasing pressure to remove the Indians from their ancestral lands. In 1850 the Federal government offered free land to settlers who would open up farms in Oregon. Prior to the passage of the Oregon Donation Land Act of September 27, 1850 (9 Stat. 496) there was no legislation by which settlers could acquire title to their lands. The Donation Land Act was passed by the Congress before treaties had been negotiated providing for extinguishment of Indian title to the land. There was growing conflict between Indians attempting to defend their
