Another section of the famous wheat country of Southeastern Washington, identified with the unmusical name of Walla Walla, borne by the oldest and best town east of the Cascade Mountains, is reached by a branch line extending from Wallula Junction. With 100,000 acres of land cultivated to cereals, with 800,000 apple trees, 100,000 pear, plum and peach trees, 25,000 grape-vines, large herds of cattle, and still larger flocks of sheep, the county of which Walla Walla is the judicial seat may be taken as fairly illustrating the varied capabilities of Eastern Washington. Scarcely less prosperous is the adjoining county of Columbia. These counties, however, being well settled, reference is made to them only as foreshadowing the future condition of those younger counties, adjacent to the Northern Pacific Railroad, which are now in course of settlement. In many of the latter the cultivation of the soil presents even fewer difficulties than in these older settled regions, in many parts of which there is scarcely an acre of level land to be found. Returning to Wallula Junction, and there resuming our westward journey, we at once enter a region of surpassing interest, none other than the famous land-- "=Where rolls the Oregon.=" Its navigable waters within 450 miles of those of the Missouri river, the great Columbia drains an area almost equal in extent to the united area of France and Germany. Excluding the portages at the Cascades and Dalles, with several less important rapids, the river is navigable to Kettle Falls, 725 miles from its mouth. These falls, on the upper river, are not accessible by rail, being a considerable distance above the point at which the railroad enters its valley. They are said to be more impressive even than the famous Cascades on the lower river, there being a perpendicular fall of twenty feet, and then swift rapids between rocky banks of quartz and porphyry. It is on the upper river, also, that there occur the Little Dalles, where the waters tear through a contracted channel with terrific force, constituting, at least at high water, an impassable barrier to navigation.
