As heretofore remarked, the agricultural conditions change suddenly on crossing the Cascade Mountains to the eastward; and this change begins at the crest line, and is more marked on the mountain side and near its base than anywhere else. The winters are longer and more severe, and the summers drier and hotter. There is natural pasturage similar to that of the plateau country, coming up to the timber line, the lower edge of which is high on the mountain. Much of this mountain land, though covered scantily with sage brush and bunch grass, is really fertile, and, besides supporting cattle, can be made to bring fair crops of wheat and other things; but the rainfall is so insufficient that irrigation is necessary for the development of any large agricultural interest. Fortunately, in the large basin of the Yakima, irrigating streams are abundant, and its enterprising people are availing themselves of this happy resource. By reference to a good map it will be seen that the Yakima River is made up of an unusual number of streams. A group of these come together near Ellensburg, and another group near the town of North Yakima; and there are said to be large bodies of land susceptible of irrigation by these streams. The Ellensburg valley is thirty miles long, and about ten miles wide; and is the best agricultural section in Kittitas County. It is claimed that forty bushels of wheat to the acre can be produced here without irrigation; and that 1,000,000 bushels of wheat were actually produced in this basin in 1887. Hay, hops, vegetables, berries and fruits also do well naturally, but with irrigation the product is uniformly large. There are four irrigating canals in the valley. The Teanaway Ditch Company has one fifty miles long which can water 75,000 acres of land. The Ellensburg Ditch Company has a ditch ten miles long, covering 10,000 acres. Mr. Bull has one six miles long, and the owners of the new roller mill have two and a half miles of ditch. Next below Kittitas is Yakima County, which contains a number of fertile valleys, and also good uplands, and is well supplied with irrigating streams, which have already been brought into use. Two large ditches are drawn from the Natchess River. Ditches are also taken from the Ahtanum, which is the principal hop-raising section. A plateau, three by ten miles, between the Cowiche and Natchess, will all be irrigated. The Moxee Valley is largely owned by Eastern and other capitalists, who seem to be expending much money in the improvement of the country. This company has fourteen miles of ditch.
