This limestone is about 75 to 80 feet above the coal in the shaft just across the river from Terro 

 Haute, which is No. 7 of the Illinois section, and the intervening beds would give the following con- 

 tinuation of the section, if carried down to the horizon of this coal ; but they do not come to the sur- 

 face in Clark county : 



No. 34. Green, blue and red clay shales 10 to 12 



No. 35. Sandstone 12 to 15 



No. 36 Argillaceous and sandy shales 45 to 50 



No. 37. Bituminous shale - 1 to 2 



No. 38. Coal No. 7 5 



The coal afforded by this seam is a rather soft, fat, caking coal, of 

 fair average quality. The lower part of the seam contains two or three 

 partings of shale. This seam would be the first workable coal that 

 could be reached anywhere in Clark county, and its approximate depth 

 at any point where it was desirable to bore for it may be determined by 

 reference to the foregoing general section. From the horizon of the 

 Quarry creek limestone to this coal it would be from 350 to 400 feet, 

 and from the horizon of the Livingston limestone from 250 to 300 feet. 



In the north-west part of this county several borings were made for 

 oil during the oil excitement, some of which were reported to be over 

 900 feet in depth ; but as no accurate record seems to have been kept, 

 the expenditure resulted in no general benefit further than to determine 

 that no deposit of oil of any value existed in the vicinity to the depth 

 penetrated. The following record of the " Old Well," or '< T. R. Young 

 well," was furnished to Prof. Cox by Mr. Lindsey :
