It seems that the Clinton diminishes in thickness in pro- 

 portion to depth, and proximity to the fault, at least, at this 

 place. Through the remainder of this section, no ore beds, 

 or any evidence of their existence, were found. They 

 seemed to have been entirely swept away. 



In the E. -J of the S. E. J of Sect. 28, same Tp., a good 

 show of ore is presented on several high points. It was 

 principally from bed No. 1 ore of average quality. The 

 pits which had been dug on it, were filled up, and its thick- 

 ness was not seen. The existence of bed No. 3 was also 

 shown by the outcrop, but it had not been opened. From 

 appearances the top bed was supposed to be 2 to 3 feet 

 thick, the other, less probably than two. 



Through the N. W. of the S. E. of Sect. 28 there is evi- 

 dence of the existence of iron on the high points though 

 very little of it was seen. Through the remainder of this 

 Section the Lower Siliceous joins the Cambrian Limestone, 

 sometimes lapping over on it. Occasionally the LaGrange 

 Sandstone is seen close to the limestone. In all such places 

 the Clinton has gone down in the fault. This arrangement 

 continues to the Township line, and in a greater, or less de- 

 gree, to the middle of Sect. 6, T. 14, R. 1 E. Through the 

 space thus passed over, though some ore has been found,
