This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1873 edition. Excerpt: ...showed the presence of considerable magnesia. I copy the analysis by Prof. Wormley, from former Report: Silicious matter 15.20 Alumina and sesquioxide of iron 4.40 Carbonate of lime, 49.80 "of magnesia 30.65 Total 100.05 Probably the whiter and purer portions of the stone contain little else than carbonate of lime. Experiments should be tried with the buff stone to determine the value of its lime for hydraulic purposes. The fossiliferous limestone 80 feet above the limestone in the bed of the creek is not the Putnam Hill limestone, as might perhaps be inferred from the Report for 1869; the Putnam Hill limestone is 72 feet higher. Sixty-three feet above this is the lower New Lexington coal mined at the Miami Company's mines in Sec. 28. The upper New Lexington eam, the equivalent of the Straitsville or Nelsonville seam, is also mined at the same mines. The seams are 22 feet apart. The lower is 3 feet 10 inches thick, and the upper 4 feet. The coal is generally of excellent quality. I have no doubt that there are in this township workable seams of good iron ore. Such ores are found north and east, and will be found here, when careful search is made. CLAY TOWNSHIP. This is a township of very limited area in the south-west corner of the county. Reference was made to it in tbe Report for 1869. No additional facts have been obtained since that Report was made. The Putnam Hill limestone is found here, and the upper New Lexington seam of coal is about 80 feet above it. The lower seam had not been found, but it maybe there in local developments. It is nowhere a very certain seam. When there is sufficient demand to warrant careful searches, I have little doubt but that valuable iron ore will be found in this vicinity. In other townships good ores more
