with the bottom of the old workings. Through 
this level the water passes off, and the pro- 
duce is brought out to be dressed, and on its 
mouth a house is built, where when the mine 
is open the overseers dwell, and the workmen 
are undressed and examined as they pass to 
and from work. 
As the mountains in this neighbourhood 
are not composed of regular strata, so this

in pipes, or bellies, at a considerable distance 
from each other. This mountain consists 
principally of that kind of rock called grey 
macké, a stratum of a darker coloured stone 
runs through it, containing more iron, the 
joints strongly tinged with oxide of iron; 
this is traversed in various directions by 
strings or small veins exhibiting traces of wad, 
and it is generally at the intersection of two 
of these veins that the valuable bellies are 
met with; in one of which, opened in 1803, 
upwards of 500 casks of the best quality 
were procured, containing about one hundred

irregular shape, and of various sizes; some
