a supposed line running south from the latter river to the California line.
The northern boundary of Champooick District was the south line of Clackamas County, i. e., the supposed line running east from the mouth of Pudding River to the Rocky Mountains, the latter being the eastern boundary of Champooick District. Its western boundary was the Willamette River and a supposed line running south from the latter river to the California line.
The boundaries of these four Districts, as adopted on the report of the Legislative Committee, are hereinafter set forth.
To make a rough map showing these four Districts, take a map of the original Oregon Country and, at a point where the Willamette River flows into the Columbia, draw a line running north to< latitude fifty-four degrees and forty minutes. Then show the Willamette River from its mouth to, say, Springfield, in Lane County, then draw a line south from Springfield to the California line. This will be the boundary separating Twality and Clackamas Districts and Yamhill and Champooick Districts. Draw a line from the mouth of the Yamhill River west to the Pacific Ocean. This will be the line separating Twality and Yamhill Districts. Then draw a line from the mouth of Pudding River east to the Rocky Mountains, this will be the line separating Clackamas and Champooick Districts.
The division lines between these four Districts were changed, several times, by Acts of the Provisional Legislature.
June 26, 1844, the division line between Yamhill and Twality Districts was changed to be as follows: "Commencing in the middle of the Willamette River, at the mouth of Pudding River; thence in a direct course to the divide of the waters in Chehalem Valley; and thence due west to the Pacific Ocean." (General and Special Laws of 1843-9, page 87.)
December 19, 1845, the division line between Yamhill and Twality Districts was again changed to be as follows: "Commencing in the middle of the main channel of the Willamette
