OREGON (314), one of the United States, on the Pacific seaboard, with Was.h.i.+ngton, Idaho, Nevada, and California on its inland borders, nearly twice the size of England, has the Coast Mountains along the W., the Cascade range parallel 60 m. E., and 70 farther E. the Blue Mountains. The centre and E. is hilly, and affords excellent grazing and dairy-farming ground; the western or Willamette Valley is arable, producing cereals, potatoes, tobacco, hops, and fruit. Between the Coast Mountains and the sea excessive rains fall.
