On the east side of the Cascade Mountains the Seattle, Lake Shore and Eastern Railway will closely parallel the Northern Pacific Railroad for a short distance in the Yakima River valley, but will probably leave it soon after entering the most productive part. The route, however, may be varied to suit circumstances, and as to this point no doubt would be if the talk of making Ellensburg the State capital should become serious. The remark may here be thrown in that this meeting of the two railroads in the Yakima valley will be no disadvantage to the Seattle road, as the distance to Puget Sound is about the same, and the incidental advantages are in favor of Seattle. [Sidenote: The Great Bend country.] [Sidenote: Douglas County.] Crossing the Columbia River, the railway will enter the great plateau which has been so fully described, and if the passage should be made at Rock Island Rapids, it will cross the plateau at its widest part. Nothing more need be said as to the great agricultural capabilities of the plateau country. The Great Bend, or northern limb of the plateau, is more extensive than the southern division, but it is a much less settled country, owing partly to want of transportation, and partly to want of water. This scarcity of water in Douglas County was formerly thought to be incurable without a resort to artesian wells; but experiment has shown that wells of good water can be obtained at moderate depths, as I was informed by Mr. Smith, a resident of the county, and by Mr. Nash, the lawyer, who owns property there. The population and, consequently, the business of this large county is limited at present, but it has a large body of good land in it, which will attract settlers before long. Its soil is of the same character as that of other parts of the plateau; but the general impression seemed to be that it was not quite equal to the land of the Snake River Basin, or to the adjoining county of Lincoln, owing in part to a larger proportion of rough land. I do not, however, consider this question by any means as settled. The best area for wheat is supposed to be that which borders on Lincoln County. If the route for the Seattle railway which is preferred by Mr. Mohr, should be adopted, it would pass across the northern part of the county, by many persons considered the best part, and leave the great body of the county out of reach to the southward.
