At Achor the cannel is about eleven feet in thickness. It crops out at 
various places between Achor and Darlington, and is in the interval seen 
to vary much in thickness, and in some localities to be replaced by bitum- 
inous coal. At Darlington the interval between the cannel and Coal No. 
6 is nearly one hundred feet, and a thin seam of bituminous coal is found 
in it. 
Such a difference in the relative positions of these coal-beds might lead 
to the supposition that there were two seams of cannel in this region. 
This can not, perhaps, be settled without more extended observations, 
but the probabilities would now seem to be that the Achor and Darling- 
ton cannels are identical, and that the variation in the interval which 
separates this from Coil No. 6 is only another exhibition of the want of 
parallelism in coal seams, so frequently shown in other parts of the State. 
The coal next below this cannel at Achor is that known in the vicinity 
as the Hartford seam. It varies in thickness, in different localities, from 
two to three feet. It is generally of excellent quality, hard, bright, 
open-burning, and pure. Thiscoal is also found on the lands of Jeremiah 
Booth and W. H. Knight in Middleton township. 
The relations of the Achor cannel and the Hartford seam to the coals 
of the central and western portions of the cownty are not yet definitely 
determined. I formerly supposed it probable that the cannel of Darling” 
ton and Columbiana county was the equivalent ef the cannel of Mahon- 
jng; and, judging from the section given hy Prof. Lesley, in his Manual 
of Coal, that both represented the Kittanning of Pennsylvania; but later 
observations have thrown considerable doubt on this identification. 
Whether the Darlington cannel is the Kittanning coal, as stated by Prof. 
Lesley, I will not pretend to decide, as this is a question that more par- 
ticularly concerns the geologists of Pennsylvania. I am inclined to 
think, however, that the Darlington and Achor cannel is not the equiva- 
lent of the Leetonia coal, which is so prone to assume a cannel character
