HAEKISON COUNTY. 207 



about one foot thick, so that the working was finally abandoned, after con- 

 siderable expenditure of money. At no point in Harrison county does 

 this bed seem to be available. 



The shales between this coal and the Crinoidal limestone are usually 

 black, with some ore, but not enough, so far as observed, to be of value. 



The Crinoidal limestone is a well-marked stratum, and though of va- 

 riable thickness is easily recognized by its fossils. It marks a well-defined 

 horizon, being in this county never more than one hundred and sixty, 

 and rarely less than one hundred and fifty feet below Coal No. 8, while it 

 holds about the same distance from Coal No. 7 below. It varies in color 

 from bluish-gray to dull brown, and weathers into rude nodules. It is 

 exceedingly hard in some layers, while in others it contains much clayey 

 matter. It is, in most localities, utterly useless, though occasionally it 

 can be burned into a coarse, brown lime. One may trace it through Moore- 

 field, Washington, Nottingham, Franklin, North, and Rumley townships, 

 but the only locality where fossils can be obtained in good condition is at 

 Deersville, near Mr. Cornelius Vickers's house. The following species 

 have been obtained at that locality : 



Productiis Prattenanus N. 



Productus Nebrascensis Oweu. 



Productus longispinus Sow. 



Productus semlreticulatua Martin, Sp. 



Chonetes SmitMi N. and P. 



Chonetus granulifera Owen. 



Hemipronites crassus M. and H. 



Ehynchonella Osagensis Swallow. 



Spirifer cameratus Martin. 



Spirifer planoconTexus Shum. 



Spirifer lineatus : Sow. 



Spiriferina Kentuokensis Shum., Sp. 



Athyris subtilita Hall, Sp. 



Bellerophon. Sp. undetermined. 

 Pleurotomaria. Sp. undetermined. 



Petalodus destructor N. and W. 



Lophophyllum proliferum > M'C, Sp. 



Zeacrinus mucrospinus M'C. 



In Moorefield and Nottingham townships a coal has been found about 

 twelve feet above the Crinoidal limestone. In Moorefield it is found two 

 feet thick, and yields a cannel of very fair quality. Upon it rests a mass 

 of black slate containing much iron ore, and which, in part, may yet 

 prove to be of some economical value. In Washington township this 

 coal is found not far from the county line on the road from Tippecanoe 

 to Brainerd's Mills. There it is broken up into a mass of coal and ferif-
