strata are in part different. A shaft, sunk a short distance from the river, 

 penetrated strata as follows : 



FEET. IN. 



1. Clay and rock, mixed 21 



2. Clay shale 8 



3. Limestone 1 



4. Clay shale, with usually a little black slate at the bottom, and sometimes all 



slate 1 8 



5. Coal, with two inch clay parting 2 6 



6. Clay. Not measured 



" Horsebacks" are very common here, and, together with the thinness of 

 the seam, render the working of this mine very expensive. The fact that there 

 are no other mines in this vicinity, alone renders the working of this one 

 profitable. 



Coal No. 4, of the Illinois section, has been found at but one place, section 

 19, township 12, range 5, where the following section was obtained : 



FEET. IN. 



1. Limestone 3 



2. Clay shale 10 to 12 



3. Coal 4" 6 



4. Cannel coal, impure " 10 



5. Clay. Not measured , 



The cannel coal, No. 4 of this section, contains the remains of fishes and 

 plants. Among the plants obtained here are Pecopteris arborescens, P. oreop- 

 teridius, P. acuta, P. cheer ophylloides, Sphenopliyllum Schlotheimn, Sphenopte- 

 ris tehella, Pinnularia , Selaginites , etc. Among the fish remains found 

 was one nearly perfect fish belonging to the genus Paleoniscus ; also, teeth, etc. 

 of a Diplodus. 



This cannel coal is seldom taken up with the main coal, and still less seldom is 

 it brought to the mouth of the mine; hence, the amount of material from which 

 I could collect was very small. Large quantities.- of a good article of coal are 

 obtained from this mine. 



The next seam below this appeared to be coal No. 2, of the Illinois section. 

 From an exposure in the bluff of Walnut creek, section 17, township 12, range 

 5, this section was obtained : 



FEET. IN. 



1. Drift. Not measured 



2. Clay and gravel stratified 3 to 5 



3. Shale 45 " 50 



4. Black slate 2 " 4 



5. Coal 1 6 



6. Clay. Not measured 



This coal lies in the bed of the creek, and can be worked only at low water, 

 most of it being covered at the time I was there. As this was the only place
