place called the ‘“‘ Whitehall Pool,” the South-Western limits 
passing under the boundary stone No. 98 on the Government 
map, and then runs in an irregular and slightly curved form to 
New Fore Pit, continuing under the Lodge, crossing Hope- 
well Colliery, in Whimberry Bottom, Perch Enclosure, and 
onwards to the deep pit on Vallet’s Level Colliery. It is again 
intersected by the Workings in Vallet’s Level Colliery in Bram 
Hill Enclosure. 
There is no certain evidence that it has been traced further 
than this, because no workings have hitherto been carried on 
in the Coleford Hill delf vein in the deeper parts of the basin. 
The North-Eastern limits of this fault runs almost parallel 
with its other line of direction described, but it appears to be 
-narrower as it penetrates the measures more in the deep. 
It varies in width from 180 to 340 yards, and appears to 
be running in a South-Easterly direction, or towards the How- 
beach Valley. A fault, also called the “Horse,” is shown to 
be crossing the North-Western boundary of the New Fancy 
Colliery, having the same direction as that previously indicated, 
but I am of opinion that it is not the same fault. 
Another fault exists between the Southern part of the 
Foxe’s Bridge Colliery and the Northern portion of the Light- 
moor Colliery, and has an average width of 300 yards. Traced 
from the Western portion of the district, it passes through the 
Rose-in-Hand Colliery; the line of its Northern limits runs 
under the boundary stone No. 125 on the Government index 
_ map inthat Colliery. It then takes a South-Western direction, 
passing between the Foxe’s Bridge and Lightmoor Collieries 
before referred to, and onwards towards Cinderford Bridge. 
The line forming the Southern limits of this fault runs nearly 
parallel with the line marking its Northern limits. That part 
of the turnpike-road opposite Lightmoor Colliery marks a 
perpendicular point in the fault below. This fault has a dis- 
placement, or down throw, of the measures of 96 feet, but 
there has been no opportunity to prove whether it extends to 
the lower coal measures, i.e., Coleford Hill delf, &c.; but as 
such faults are known to affect all the seams in other coal
