SUPPLEMENTAL EEPOKT — HANGING ROCK DlSTEICT, 931 



The section on the left hand side of the page embraces a part of the 

 measurements obtained on the Monitor Furnace lands, directly opposite 

 Ashland, Kentucky. Repeated mention has been made of this section 

 in the preceding pages, and it will now be described with necessary de- 

 tail. The whole section obtained in this hill is the most complete yet 

 found in the district. A large number of the best known elenjients can 

 be identified, and the hill rises so abruptly that most satisfactory and 

 reliable measurements can be obtained. It embraces all that the two 

 sections represented in the diagram" contain. The block ore, which if 

 the base of the Ironton section, is found near the level of low water in 

 the river. The several elements agree with the descriptions already given 

 as far as they extend. The part that remains to be described is the in- 

 terval between Coal No. VI and the Cambridge Limestone. 



In regard to the Sheridan Coal, which makes the base of the second 

 section, nothing needs to be added. 



It is overlain, sometimes with the interposition of a few feet of shal" 

 and oftener without, by a heavy ledge of sand-rock. This is one of the 

 well marked strata of the valley for ten or fifteen miles. It is th-e 

 "hanging rock" that overlooks the village of this name, and so ha-* 

 come to give a dejignation to the entire district. 



At forty feet above the coal, a seam of ore, well known throughout the 

 furnace district on both sides of the river, is found. It is designated in 

 the section as the "Yellow Kidney" Ore, but no such name can Ijh 

 depended on without proper verification of the seam, for it will be 

 found that the "Yellow Kidney " of one furnace is the "Red Kidney " of 

 the next, and the " Black Kidney" of still another. The name most fre- 

 quently applied in the immediate vicinity has been adapted here. Thi?' 

 is a mellow and excellent ore that is welcomed by every furnace of tlie 

 region. The seam is about one foot thick in its development, and i r 

 quite persistent. A few feet of shale intervene between it and the sand- 

 stone that supports it and it is also overlain by shale and shaly sand- 

 stone. 



The Hatcher Coal was not opened in the Monitor I^'urnace hill, but itt< 

 place is indicated in the section. It is found in the immediate neigh- 

 borhood at an elevation of forty-five to fifty feet above the Sheridan 



seam. 



At sixty -six feet above the last named coal a BufF Limestone, two fttt 

 thick is met. It is an element in almost every section of this regicn. 

 It is overlain very often by a seam of ore. The ore is shown in the sec- 

 tion at seventy feet above Coal No. VI. It has been quite extensively 

 worked on the furnace lands, and a good report is always given of it
