EDDY : LEAD VEINS

before speaking of the nature of the vein itself. The deep adit 
driven east nearly to, and west to the ends of the mine : the middle 
level, 10 fathoms higher, originally driven from a rise eastwards 
and extended to near the east end, and westward beyond Taylor's 
shaft; the upper adit, 10 fathoms higher still, extending from 
the surface eastward the whole distance ; and Briggs level, a 
superficial adit, begun at the surface east of the engine shaft and 
continued to the east end of the mine. Below the deep adit, the 
15 fathom level was driven some distance east and west go a distance 
beyond Taylor's shafc, the 25 a short distance east and west of 
Engine shaft crosscut, and the 45 fathom, level which extended but 
little from this crosscut. There is also an old adit crosscut driven 
from the south-west side of the hill in the Glusburn ground, with two 
small shafts upon it, but this does not communicate with the mine 
proper. The principal shafts are Taylor's, at the end of the main 
crosscut sunk to the deep adit level, eastward from this the engine 
shaft to the 45 fathom level below the deep adit ; and Garforth's 
and Mason's shafts both sunk to the deep adit only. In this 
part of the mine an "inclined plane," or shaft, was extended 
from the surface to the deep adit eastward. Westward of the main 
crosscut are Remfry's shaft to the deep adit, and Good Hope shaft, 
which has of late years been sunk to a level about 10 fathoms below 
the deep adit. 
At this, the western part of the mine, exists the only chance I 
know of at present for any further development of the Cononley 
Main Yein. 
The principal crosscuts which have practically proved the 
worthlessness of the side veins north and south of the main fault 
vein are, eastwards, the old Glusburn adit crosscut, Brigg's crosscut, 
the middle level north and south, and the upper adit south ; in the 
centre of the works the upper adit north, middle level south, deep 
adit north, and the 15, 25, and 45 fathoms crosscut south. In the 
west end, the deep adit south, and one north (not shown on plan). 
Besides these works there have been drivages at the upper
