fields, we cannot consider that the fault under consideration 
will prove an exception to the rule. Workings were formerly 
carried downwards in the Coleford Hill delf seam from a pit 
sunk at Quidchurch, in Stapledge Enclosure, a little to the 
West of Shakemantle Pumping Pit, and at a point a little to 
the South of Cinderford Bridge a fault of considerable thick- 
ness was reported to have been discovered running in nearly 
the same direction as the last preceding fault referred to, 
between Foxe’s Bridge and Lightmoor Collieries, but the 
administration in connection with the working of the Quid- 
church Colliery was not of such an order to permit of accurate 
observations, and as the works have been abandoned and are 
now full of water, no verification of facts referring to this fault 
can now be made. If the fault existing between the Lightmoor 
Collieries and Foxe’s Bridge should continue in a perpendicular 
plane to all the coal measures below, which is highly probable 
separating the middle and lower series of coal seams as it has 
done in the upper measures, it would prove of great service, 
tending to dam back the water existing in the lower measures 
of the Northern portion of the Forest of Dean coal field, and 
consequently the drainage of the seams of coal existing in the 
deep in the Southern portion of the coal field would be 
diminished to a very considerable extent. Notions of insuper- 
able difficulties in reference to a proper and economical drainage 
of the coal measures South of the Lightmoor fault would 
doubtless become more visionary than real. 
A little to the North of the China Engine Pumping Pit, 
on the Western side of the Forest district, and at a short dis- 
tance from the lower boundary line or fence of Heaven’s 
Meadow, a fault or dyke filled with a reddish foreign rock, 
locally termed Duns, was found completely displacing the iron- 
ore measures in the China Engine workings, which were carried 
Northwards. Shallow exploring pits were made at various 
points along Heaven’s Meadow, Northward, and at a few feet 
the top of the fault was laid open in each pit. The fault 
appeared to be running from the North-West to the South- 
East, crossing the iron-ore measures almost at right angles,
