2£Q Mr. Farey's Account of 
At the SW. corner of the Weaver Hills abovementioned, 
the great limestone fault again leaves the south boundary, or 
great Derbyshire fault, and proceeds northward, after which 
a corner of the second interior raised tract again presents it- 
self, and the limestone-shale again abuts on the marie, as we 
pursue the great Derbyshire fault to the westward, owing to 
the rise being less here by four or five hundred yards, than 
it was in the third interior tract ; but as we proceed south- 
westward, owing to the dip of the measures on the N. side of 
the great Derbyshire fault towards the west, the first grit, the 
first coal-shale, and the second grit rock successively abut 
against the marie, before the gravel covering commences, 
east and south of Cheadle, which prevented my tracing this 
fault any further, within the limits of my Survey. 
It seems probable, however, that somewhere SW. of Chea- 
dle in Staffordshire, a branch sets off from the great Derby- 
shire fault, or southern boundary of the lifted tracts, and 
proceeds northward, near to Endon and Bosley in Cheshire ; 
the triangular tract beyond which, to the westward, shewn in 
the map, forming the pottery coal-field, is much less raised, 
perhaps, than any of the other tracts which have bebn here 
mentioned. 
If we return to Allestry N. of Derby abovementioned, and 
trace the zig-zag fault, through Little Eaton, West Hallam, 
and Ilkeston in Derbyshire, Awsworth, Greasley, Annesley s 
Kirkby, and Dirty-Hucknal in Nottinghamshire, Alt-Huck- 
nal, Bolsover, Clown, and Barlborough in Derbyshire, Hart- 
hill, South-Anston, North-Anston, Dinnington, &c. in York- 
shire, we shall find coal-measures on both sides of it, through 
its whole length, except in two or three instances, where the
