Oregon Divided Into Four Districts. In December of 1843, the Legislative Committee created four legislative districts which, in 1845, were called counties.

Twality District was bounded on the north by the northern boundary line of the Oregon Country. Its eastern boundary was the Willamette River, and presumably an extension of a line from the mouth north to the north line of the Oregon Country; its southern boundary was the Yamhill River and presumably a line which would be the western continuation of the Yamhill River to the Pacific Ocean, said ocean being the western boundary of Twality[1] District.
Yamhill District was bounded on the north by Twality District, on the east by the Willamette River and a supposed line running north and south from said river to California, on the south by California, and on the west by the Pacific Ocean.
