in two benches ; the lower (bituminous) twenty-four to thirty inches ; 

 upper (cannel) six to twelve inches. 



6. Solomon Poland's bank, Section 7, coal thirty inches ; lower bench 

 (bituminous) twenty-two inches ; upper (cannel) eight inches. 



7. David Poland's bank, Section 6, coal twenty-four to thirty inches, 

 with six inches of cannel above ; lower bench, bright and handsome, re- 

 sembling the Leetonia coal. 



Coal is also reported opened on the land of J. McCuUough, G. Myers, 

 Sarah Hans, and J. W. Heindle. 



At Petersburg, Coal No. 4 is mined in several places ; in some, a rather 



poor bituminous coal ; in others, a good cannel. Two outcrops of coal 



are seen above it, but they have not been opened. The section of the 



hills here, though partially concealed, is as follows : 



FT. n*. 



1. Slope, covered, with thin streak of coal near top 50 



2. Coal, heavy outcrop, 



3. Slope, mostly sandy shales , 85 



4. CoalNo.4 2 6 



In this section, the strong outcrop of the second coal is probably Coal 

 No. 6, and perhaps the streak of carboijaceous matter at the top of the 

 hill represents No. 7. Unfortunately, no limestone is visible here, and 

 we get little to help us in the correlation of the Lowell section. . If, as 

 some have supposed, the Lowell Limestone is the equivalent of the white 

 limestone, it should lie seventy or eighty feet above Coal No. 4, or just 

 below the outcrop of Coal No. 6 ; whereas, if its place is below Coal No. 4, 

 it should be found within twenty feet of that seam ; but, so far as we 

 could learn, no such limestone has been struck in any wells or borings in 

 this vicinity. 



BEAVER. 



The surface of this township is generally rather level, and few out- 

 crops of the strata are seen. Coal has been mined, however, in a great 

 number of localities, but so far as we could learn, only one seam. No. 4, 

 has been opened. The principal mines are as follows : In the south 

 part, P. B. Yoder's and J. Wilderson's; in the east part, G. W. Heindel's 

 A. Yoder's, and G. Mercer's; in the north part, Azariah Paulin's, David 

 Sprankel's, and George Coler's. The cha'racter of the coal varies very 

 much in these different openings ; for example, at A. Paulin's it is twenty- 

 eight to thirty-two inches thick, with eight or ten inches of cannel above. 



On the Sprankel farm, it is six feet thick, all cannel, of good quality, 

 the average of several proximate analyses, showing about 15 per cent. 

 of ash. On the next farm, that of George Coler, it is all bituminous, 

 and at the mine of Jeremiah Brown, already referred to, in the adjacent
