In the first hole, the Brier Hill coal was undoubtedly struck ; in the 

 second, it is wanting, or is represented by a black shale. It is probable 

 that borings made near the first hole, but further north, would strike the 

 Block Coal,"of greater thickness, as the basin probably extends in this 

 direction. 



BOAEDMAN. 



But little has yet been learned in regard to the economic resources of 

 Boardman township. Coal No. 1 has been struck in borings made for 

 Mr. C. H. Andrews, near the north line of the township ; but up to the 

 present time no considerable basin of good thickness has been discov- 

 ered. The limestone coals are here apparently thin, and of little value ; 

 and Coal No. 4 has only been opened in the south-west corner of the 

 township, at the Powell mine, which is not now worked. 



CANFELD. 



The outcrops of Coal Nos. 3 and 3a, in the northern part of Canfield, 

 have been already alluded to. Coal No. 4 has been proved, by explora- 

 tions made by Mr. Wm. Wetmore, to underlie the Academy Hill, but it 

 has little cover, and is not regarded as of great value. It also underlies a 

 detached hill on the Swanton farm, east of town, but has not been opened 

 there. On the banks of Indian Creek, below the place of Coal No. 4, are 

 outcrops of Coals No. 3 and Sa, with two limestones ; and it is said that 

 the Block Coal, three feet in thickness, was reached here by boring, one 

 hundred and forty feet below Coal No. 3. 



Mr. Wetmore reports that he found Coal No. 4 four feet thick, from 

 twelve to fifteen feet below the grade of the railroad, on the land of War- 

 ren Hine, west of the Fair Grounds. It had there no roof and was 

 covered with gravel and sand. He states that in one place it was folded 

 up into an arch, evidently by lateral pressure, probably that of the 

 glacier which once covered the surface here, moving southward. There is
