e manganese is of an indigo colour, its gangue quartz, 
which is often yellow, although much of it is milk white. 
Particles of a steel gray metallic pita! insensible to the mag- 
net, are seen disseminated in the manganese. 
No 8 is in the east part of Conway. I know but little 
about this mine, and have put it down only to excite atten- 
tion. I was at this place several years since, and saw a vein 
of quartz in granite, a crystalized, and some rounded 
masses containing galen

vein has not been actually seen, but large blocks of quartz, 
much crystalized, are seen ina range, several rods wide, and 
one-fourth of a mile long, scattered in great profusion. The 
vein is evidently covered with geest. The blocks, upon 
breaking them, show the radiated quartz in abundance, and 
are rich in galena, with considerable pyritous copper. The 
galena is frequently in various stages of oxidation, and often 
the red oxide of lead (?) is found. Upon breaking open a
