and as its width was found to be very considerable, and taking 
into account that the great body of water retained or damed 
back towards the North as far as Coleford, by this fault would 
have flooded the works if they had been continued through the 
entire fault, the exploring headings for iron-ore, Northwards, 
were abandoned, and up to the present time have not been 
resumed. 
Whether any connection exists between this fault and the 
dislocation of the strata in the Carboniferous Limestone at 
Howbeach, may, perhaps, never be determined, but it certainly 
does seem to run in that direction. 
At St. Annals Iron Works, near Cinderford, the contortions 
of the strata were so great that the pit sunk there passed 
through the same bed of rock two or three times, which, with- 
out explanation, would appear to be very anomalous. The 
general dip should have been in a Western direction, taken 
from the outcroppings, but at certain depths the beds of lime- 
stone rock and iron-ore measures were perpendicular, and at 
others it had a reverse order of dip, or towards the Hast for 
limited distances in depth. For example, at a perpendicular 
depth of 175 yards, a cut-out or horizontal gallery was driven 
from the pit Eastward for a distance of 117 yards to the inter- 
section of the iron-ore measures, but at a further depth of 44 
yards, or a total from the surface of 219 yards, a second cut-out 
was also driven from the bottom of the pit towards the East 
_ for a horizontol distance of 118 yards, also intersecting the 
_ iron-ore measures. Thus it will be seen that for the last depth 
of 44 yards the dip was one yard out of the perpendicular 
towards the East, or equal to an angle of 1° 18’ 0”. Thisisa 
__ very curious example of the lateral folding of the rocks caused 
_ by the immense forces which produced the anti-clinal lines 
previously referred to. It is probable that its occurrence was 
identical in point of time with the dislocations formed in the 
_ same measures in the Howbeach Valley, but of less violence. 
Some distance to the West of St. Annals Iron Mine 
excavations were made in the Millstone Grit rocks, and there 
it is seen that the contortions in the limestone have also been
