l.Map XIII., No. 23.) 



The List three items of the above section are not included in the map. 

 The limestone in No. 18 of the section is sometimes burned into lime. 



The fume seam of coal seen on Mr. Raper's land is mined by Mr. George 

 Shy, who lives also in section 34. The seam measures three feet, the 

 upper part showing the usual slaty character. Iron ore is found thirty 

 feet below the coal. It is not yet known to constitute a regular layer. 

 Mr. Shy bus dug a ton or more of it. A sample of the ore was analyzed 

 by Prof. Wormley, and found to contain only 12.13 per cent, of metallic 

 iron. 



CENTER TOWNSHIP. 



Tin's township is central in the county, and in it is Woodsfield, the 

 county feat. Sunfish Creek flows through it on the northern part, and 

 branches of the Little Muskingum drain the southern portion. 



The seams of coal in this township are, so far as seen, thin, although 

 they are mined for the home supply. Some very superior iron ore is 

 found in the red clay shales west of Woodsfield. 



The following geological section is a grouping of the more important 

 strata seen in passing from Woodsfield north, down into the valley of 

 Sunfish Creek:
