ORES OF THE CHAMPLAIN, TACONIC AND METAMORPHIC ROCKS.

which is of quartz, containing galena, blende, copper pyrites, etc. is about four inches wide 
at the surface, and widens downwards, but is very irregular in width, and branches off into 
bunches and strings. It is nearly vertical, and ranges S. 70° W. and N. 70° E. The strata 
dip eastwardly sixty to seventy degrees. The ores from this mine, when mixed, are said to 
yield one hundred and eighteen ounces of silver to the ton.* The mine is situated on a hill¬ 
side near a small stream called Punch brook. Many small veins of quartz, calc spar and 
brown spar, traverse the strata in different directions, and most of them contain small quanti¬ 
ties of galena and blende. The principal vein has its outcrop parallel to the strike, and it 
passes downwards through the rocks nearly vertically, while the strata dip to the east as above 
stated. It seems then to be a proper vein. The geological relations of this mine are indi¬ 
cated, as far as is known, on Plate 23, fig. 4. The striped stratified part represents the 
slate, and the checkered part the sparry limestone. Dr. C. A. Lee described this mine in 
1825.t 
Prof. Beck thus describes this locality : 
“ At this mine two or three veins of galena may be observed on the surface, which with 
their gangue vary in width from a foot to three or four feet. When they widen, as they 
sometimes do, the ore is very sparingly disseminated in the calcareous spar and quartz, which 
constitute its principal associates. 
“ The occurrence of the lead ore at this locality, reminded me of that of the copper ore at 
Flemington, New-Jersey. It does not appear to constitute a true vein, but to be a collection 
of strings communicating with beds of various dimensions. These strings are parallel with 
the strata, and not at right angles to them; and in no case did I observe the ore separating 
from the walls, as it often does at the Rossie vein, but it gradually loses itself in the accom¬ 
panying rock. 
“ The mine seems at present to be judiciously worked, although I have reason to believe 
that it has not answered the expectations of the proprietors. The principal shaft is about 
seventy feet in depth, and from this runs a shore level which communicates with another 
shaft, opened many years since, and which now performs the part of a ventilator. At the 
base of the hill, a level has been commenced, which is intended to cross the deposit of ore, 
and will, when completed, be about one hundred and Miy feet (yards ?) in length. 
“ The galena is both crystalline and granular. It is associated with quartz, and occasionally 
has mixed with it some carbonate of lime. But the former constitutes the principal gangue, 
and the difficulty of separating it from the ore renders the processes necessary for its reduction 
comparatively tedious and expensive.
