vein, at Newbury, would appear to have passed beneath the 
Limestone for a distance of 40 yards. If, however, the Limestone 
extends farther westward, as suggested in an earlier part of this 
paper, and as shown by dotted lines on the diagram, the Newbury 
workings may really have been farther under the patch than is 
generally supposed. 
In a garden, behind some cottages at Upper Vobster, marked A 
on plan, a well was sunk many years ago, by Mr. Richard Edgell, 
a bailiff at the Vobster Colliery. It began in Mountain Limestone, 
but at a depth of 22 feet from the surface it passed into Coal 
Measures, in which it was continued 4 feet, making a total depth 
of 26 feet. This information I have obtained from Mr. Edgell 
himself, who is prepared to vouch for its accuracy, and who has 
also communicated another important fact. At the time the well 
in question was sunk, the workmen at Upper Vobster quarry 
having followed the Limestone a little deeper than usual, at a 
point marked B, passed through it into shale, and it was ascer- 
tained, by levelling the ground, that the shale at the bottom of 
the well A was on a level with the shale met with at the bottom 
of the quarry. 
A little nearer Bilboa, at the point marked C on the diagram, it 
is said another well was sunk through the Limestone into Coal 
Measures, but of this I am not in a position to speak with certainty. 
In the corner of a field adjoining the coal-yard at Bilboa, on the 
south of the patch, are the remains of an old shaft, and I have 
been informed upon reliable authority that its workings passed 
beneath the Limestone. At a depth of eighty yards from the 
surface a branch or gallery was driven north more than 100 yards, 
and the men who worked in this branch are said to have been 
within hearing of the workmen in the Dunny drift vein at Upper 
Catch pit situated in the northern side of the patch. 
In the case of the Tor rock area also it has been alleged that 
the workings of adjacent pits have met beneath the Limestone, 
but after some enquiry I have been unable to satisfy myself of the
