The two last metals were discovered by the late Mr. Stoppart, (see paper 
read before the Bristol Naturalist’s Society, Vol. IJ., Part 1., 1876-7. New 
Series.) He found in 100 parts of the Limestone ‘003 of Silver. Mr. Merry, 
of Swansea, has verified Mr. Sroppart’s observations as to Gold ; he found 
three grains per ton.

Extract of a Letter from Mr. W. Buancu Brain, St. Annals, Cinderford. 
The principal Mineral in the Forest of Dean is the Red Hematite 
Iron Ore, which is found in Lodes (locally termed Churns,) and contained 
in a Rock called by the miners the Creese Stone, and which is situated 
above the Mountain Limestone. This Ore is extremely valuable for Steel 
making, being perfectly free from Phosphorus. It is to be found in the 
lower basin of the Forest, which extends throughout the Forest, and can 
be seen to the best advantage at the following mine works, viz. :—Wigpool, 
Edge Hill, St. Annals, Buckshaft, and Shakemantle. 
There are some Argillaceous Ores which occur in the Coal Shales, but these 
have not been worked to profit to my knowledge. They are to be found in 
small quantities at almost every colliery in the Forest. 
I should have said at the St. Annals mine works before alluded to, there is 
found with the Red Hematite Iron Ore a beautiful Ochre. 
In the lowest Coal Seam called the Hildelph Vein occurs a small quantity 
of Lead, yielding a low percentage of Silver. 
A quantity of Iron Pyrites (locally termed “‘ Dogs,” because they form 
blocks like Stone) is to be found in a Vein of Coal named the “ Twenty 
Inches.” The Pyrites are very detrimental to the Coal (being very heavy, 
and have to be cut out,) and the former is insufficient to guarantee a manu- 
facture of Sulphur, although such a process has been contemplated.
