This is the bottom group of the Washington Territory coal field. It will be seen that, taking the Gilman group, the Raging River group, and the Snoqualmie group on one line, and the Cedar River, Carbon River, and Green River group on another line, it may be fairly claimed that there are at least fifteen working seams of three feet and upward in the Washington Territory coal field. _e. The Yakima and Wenatchie Group._ This field lies on the east flank of the Cascade Mountains, on the waters of the Yakima and its tributaries, Cle-ellum and Teanaway. It is believed to extend also into the Wenatchie Valley, although the area here is probably disconnected from the Yakima area. I purposely refrained from visiting this region, and for my statements I am indebted chiefly to Bailey Willis, F. H. Whitworth, Charles Burch, and Mr. Jamieson of the Kirke Mines. [Sidenote: Yakima or Roslyn coal field.] The Yakima area lies north of the Yakima River, near to the Northern Pacific Railroad, and to the projected line of the Seattle, Lake Shore and Eastern Railway, and extends about sixty miles east and west, and six miles north and south. Its dip is gentle, say twelve to twenty degrees. It holds three coal seams of 2 feet 6 inches, and 5 feet and 5 feet respectively. There is not much evidence of fracture in any part of the field. The total thickness of the coal-bearing rocks is estimated by Bailey Willis to be 1,000 feet. This is evidently the lower part of the coal series, the upper part having been carried away. The best seam is mined at Roslyn, four miles north of the Northern Pacific Railroad, in the interest of that railroad. The seam here furnishes upward of four feet of good coal. The coal is bituminous, dull black, firm, and free burning. Mr. Jamieson thinks it will not make good coke. Others, however, think that it will, and these are supported partially by the laboratory test in Washington City, D. C. (See Table of Coal Analyses, page 107.) It is called in the table Roslyn coal. This coal is used chiefly in the locomotives; but the popular demand for it is very great in the plateau country of East Washington. [Sidenote: Coal on the Wenatchie.] I have no knowledge of the coal on Wenatchie River except what I obtained from Mr. Burch, who says that there are two seams of coal exposed in that valley, one of eight feet and one of three feet. The coal-bearing rocks extend for thirty-five miles up the river, and have a width of ten miles. [Sidenote: Coal under the Great Bend country.] The coal is reported by Mr. Burch to appear east of the Columbia River, opposite to the fields just described, and to disappear under the basalt. If so, here is a resource for the future. Concerning the importance of this coal field to the Seattle, Lake Shore and Eastern Railway, I will speak in another connection.
