A State of the American Union, in the NW., lies along the Canadian border between Idaho and the Dakotas, with Wyoming on the S.; has a mild climate, and a soil which, with irrigation, produces fine crops of grain and vegetables. Cattle-raising is profitable, but the chief industry is mining, in the Rocky Mountains, which occupy a fifth of the State. There gold, silver, copper, and lead abound. The Missouri and the Columbia Rivers rise in Montana, and the Yellowstone traverses the whole State. The State was admitted to the Union in 1889, with Helena as capital.
