clay seams, each six inches thick ; coal of good quality. On Stoker's 

 Hill, south-west of Mitchart's, an outcrop shows coal one foot, fire-clay, 

 six inches, coal, eighteen inches. 

 On Mr. Ellison's land, in the same township, an outcrop gives —

On Joseph Blanchard's land, three-fourths of a mile south-east of Napo- 

 leon, is an opening, of which the following is a section :

1 Shale 20 



2. Coal 10 



3. Fire-clay 8 



4. Coal 8 



5. Fireclay 10 



6. Coal 1 8 



7. Black shale. 



It is evident that such a seam, thoagh containing nearly four feet of 

 coal, will be of little value unless the clay partings thin out. In all of 

 the hills around Napoleon this coal is well developed, but all the expo- / 

 sures found, showed clay or shale partings, rendering the coal of little 

 value for present mining. 



Elias Mast's mine, in Hardy township, east of Millersburg, has a firm 

 limestone roof, admitting of chambers fifty to eighty feet wide, timbered 

 only along the railways ; coal hard, bright, and of good quality. The 

 following is a section of the coal strata : 



1. Limestone 4 ft. 



2. Coal 18to20in. 



3. Fire-clay Sin. 



4. Coal 2 ft. to 2 ft. 10 in. 



5. Blackshale i 20 in. 



6. Cannel coal - 1ft. 



Michael Cullens's bank, in Salt Creek township, gives the following 

 section : 



1. Limestone 3 feet. 



2. Coal, rotten and soft 2 " 



3. Hard gray shale 2 " 



4. Coal, good quality 2 " 



5. Fire-clay 18 to 20 inches.
