1 hope, however, now to be able to prove— 1. That there 
is no vertical elevation of the beds of the whole country, on 
the North side of the valley of the Don, or, that the pre- 
viously described elevation is merely local ; — 2. That the 
supposed lateral movement is due, in reality, to a depres- 
sion or synclinal axis of the beds on the South side. 
It is, indeed, true that there is a vertical elevation, in the 
beds of the North side, over those of the South, if you com- 
mence at Iccles Hall, and trace any of the deeper beds as 
far only as Keppel's Column ; but, in this case, part only of 
the disturbed country is described. These disturbances ex" 
tend over a much greater tract of country than is generally 
supposed : for instance, in the Thick coal they commence on 
the borders of Derbyshire, and extend as far as Elsecar ; so 
that the whole country from Orgrave, near Beighton, and 
perhaps beyond it, to Elsecar, North of Wentworth House, 
is disturbed by variable and sudden inclinations of strata to 
the horizon, by one synclinal, and probably tv;o anticlinal 
axes, and is more or less broken by faults of considerable 
magnitude ; — similarly, the disturbances commence in the 
Sheffield coal, North of Birley Moor, and terminate only at 
Chapel Town ; and in the Gannister, at Dore, three or four 
miles on the South side of Dronfield, and terminate only at 
Deep Car ; but beyond the two points where each of these 
beds first becomes regular, or assumes its usual inclination 
to the West, there is indeed no material elevation of one side 
of the country above the other. 
In order to prove this, it is only necessary to ascertain 
the difference in elevation above the sea, or between each 
look place. The proofs in support of a vertical movement were, the abrupt rise 
of all the beds to the North, between Rotherham and Sheffield ; accompanied 
with several faults, which elevate the beds to the North, both of which are seen 
in Mr. Chambers' Works, at the Holmes, and on the line of the Sheffield and 
Rotherham Railway. These are furtber explained in the sequel.
