the coal lies flat in the water; and several pits, sunk through it, are 
deeper than the height of aman. The bed must be nearly, or quite, six 
feet, and yields good coal (as indeed it does at the other openings); but 
what its constitution may be I do not know. It is probably subdivided 
into benches of different qualities ; and, no doubt, has some of the slate 
of the above last section running through it. Its position on the anticli- 
nal will make mining difficult.

The anticlinal disturbance at Scott’s Mines on Middle Creek must be 
‘local ; because the topography around the Salt Well shows that the Coal 
Measures there come up to the Downthrow in a flat and undisturbed con- 
dition ; and the dying down of the crown of the anticlinal in the Six-foot 
bed so rapidly that the bed lies flat in the creek only a few hundred 
yards above where it plunges at angles of 40°, 50° and 60° proves the 
same thing. 
throughout the body of Stony Ridge makes the whole disturbance of con-| 
siderable magnitude ; and I have no doubt that when it is well examined 
to the eastward, it will be found to run in that direction some miles ; not, 
perhaps, as an anticlinal but as a downthrow ; and it may very well be 
the Abb’s Valley Downthrow, of which more hereafter.
