KNOX COUNTY. 317 



township 12, range 4. No work was being done at the time I was here, but 

 another mine just over the line in Stark county, was open. As they are but a 

 short distance apart, the following section, which was taken from the latter, 

 will probably show the general character of the strata : 



FEET. IN. 



1. Limestone 3 



2. Clay shale 10 to 12 



3. Coal 4 " 6 



4. Impure cannel coal 6 in. to 10 



5. Clay. Not measured 



In the cannel coal, No. 4 of this section, there are the remains of fishes and 

 plants, some of which are beautifully preserved, though generally quite frag 

 mentary. 



The mines along Sugar creek and its branches, in township 12, range 3, may 

 belong to this seam, or perhaps to No. 6, but as none of the banks were open, 

 I could not make the necessary examinations to determine this point. The 

 coal furnished by these mines was reported to be of superior quality, and this 

 would seern to indicate that it belonged to No. 6. 



The mines in sections 9, 16 and 32, and along Middle creek and its branches, 

 in the northeast part of township 11, range 2, also those in section 25, town- 

 ship 11, range 1, are probably in coal No. 4, or possibly in No. 5. 



South- of Spoon river, there are a number of mines along Littler's creek, in 

 sections 26, 27, 28, 34 and 35, township 9, range 3. A section here gave: 



FT. IN. FT. IN 



1. Black slate 1 3 to 2 



2. Coal 3 6 to 4 6 



3. Fireclay 1 6 to 2 



The mines in section 3, township 9, range 4, and sections 26 and 27, town- 

 ship 10, range 4, may also belong to this coal, but the evidence was quite un- 

 satisfactory. The following section was reported from section 26 : 



FEET. 



1. Sandstone 3to 5 



2. Clay shale '. 8 to 12 



3. Clay 2 



4. Black slate 2 to 4 



5. Coal 2 to 3 



6. Clay shale. Not measured 



This seam, though not as extensively worked as No. 6, underlies a much 

 larger portion of the county. It probably underlies township 13, ranges 2, 3 

 and 4, and the eastern part of range 1. 



A short distance southwest of Milroy, a thin seam was reported somewhere 

 from twenty to forty feet below the one now worked there, which appears to be 

 No. 6. Should this lower seam be No. 4, it is much thinner here than it is
