I am able now to state that this has been verified. During 
one of the excursions of this Club in the autumn of 1880 to 
Vobster, after having examined a drift which had been carried 
through some Coal Measure shales, and whilst Mr. MeMurtrie, 
Mr. Sandys, and myself were proceeding to join the rest of 
the members who had gone to Coleford for lunch, some infillings 
on the surface of the Limestone attracted my attention; on 
closer inspection these proved, to our delight, to be formed 
of Millstone Grit. In the “Summary of the Proceedings ” 
of that year allusion was made to this as tending to throw 
additional light upon the geological puzzle of the neighbourhood, 
and it was thought worthy of being recorded at some future 
time more in detail, as an interesting fact to be added to the 
others accumulated by Mr. McMurtrie on this question. Since 
then, however, I have been fortunate enough to find much 
additional evidence in this direction. 
The work of quarrying the Limestone for road metal and lime 
burning has recently been carried on very actively, and during a 
visit paid at the end of last October I found not only that the face 
of the quarry had been much altered by a large fall of rock and fire 
clay, calculated at about 40 tons weight, but that another one had 
been opened in the rear to the north. Access to this was obtained 
by means of a cutting about 5ft. wide, 6ft. deep, and 60ft. long ; 
the rails for a small tram-car to run backwards and forwards were 
laid upon the upturned edges of the Mountain Limestone, and it 
had been cut through a “heading” composed of yellowish and 
reddish clay and Millstone Grit blocks distinctly and evidently in 
situ. There was no mistaking these to be a few stray blocks 
scattered here and there ; they were of all sizes and shapes, from 
a large block 314 inches long, 21 broad, and 103 thick, to small 
fragments of afew inches. The blocks were angular or subangular, 
and had plainly been detached from their parent mass not a great 
distance off,
