POUNCEFORD QUARRY. 
222 
The Forest Ridge, along which the main road 
passes, consists of sand and friable sandstone, more 
or less ferruginous. Descending the narrow wind- 
ing way that leads to Pounceford, occasional open- 
ings occur in the wliite varieties of the sandstone, 
along the sides of the deep valleys j shale and blue 
clay appear on the surface ; and springs issue from 
the defiles of the glens, the water being thrown 
out by the argillaceous partings of the strata. 
Before reaching the bottom of the v'^alley, to which 
the road conducts, limeworks are seen, on a rising 
ground on the left hand ; and, to the right, a path- 
way leads, by a farm-house, to a deep glen, where 
a quarry has been opened, and from whence an 
incrusting spring has its source. This quarry, 
moreover, presents a most interesting section to 
the geologist ; for there, in situ, is seen a bed of 
the Tilgate stone, beneath a layer of the Ashburn- 
ham bivalve limestone : it is not a little extraor- 
dinary, that the occurrence of calciferous grit, in 
this division of the Hastings beds, should have so 
long eluded observation. The quarry, of which a 
sketch, by my friend Warren Lee, Esq., is annexed, 
is composed of —
