In the Golden State dry-farming is a fully established practice; it has long since passed the experimental stage. Columbia River Basin The Columbia River Basin includes the state of Washington, most of Oregon, the northern and central part of Idaho, western Montana, and extends into British Columbia. It includes the section often called the Inland Empire, which alone covers some one hundred and fifty thousand square miles. The chief dry-farm crop of this region is wheat; in fact, western Washington or the "Palouse country" is famous for its wheat-producing powers. The other grains, potatoes, roots, and vegetables are also grown without irrigation. In the parts of this dry-farm district where the rainfall is the highest, fruits of many kinds and of a high quality are grown without irrigation. It is estimated that at least two million acres are being dry-farmed in this district. Dry-farming is fully established in the Columbia River Basin. One farmer is reported to have raised in one year on his own farm two hundred and fifty thousand bushels of wheat. In one section of the district where the rainfall for the last few years has been only about ten or eleven inches, wheat has been produced successfully. This corroborates the experience of California, that wheat may really be grown in localities where the annual rainfall is not above ten inches. The most modern methods of dry-farming are followed by the farmers of the Columbia River Basin, but little attention has been given to soil-fertility, since soils that have been farmed for a generation still appear to retain their high productive powers. Undoubtedly, however, in this district, as in California, the question of soil-fertility will be an important one in the near future. This is one of the great dry-farm districts of the world.
