IMPROVEMENT IN OREGON.-Already has a canal been commenced
around the dangerous falls in the Columbia river, at Willamette, by Dr. McLauglin, an
American citizen. Its length will be about half a mile, part of the way through a solid bed
of primitive rock, and the fall in the entire distance will be about thirty-five feet. The
projector expects to complete the work in two years, at a cost of thirty thousand dollars.
His charter, procured from the Oregon Legislature is to twenty-one years. It is said that
the improvement which will be effected in the navigation of the Columbia, by this
construction of the canal will, of itself, fully reward the community for the privilege
conferred by the Legislature.
