or fifteen degrees from a perpendicular ; is six or eight feet 
in diameter, and traverses granite and other primitive rocks. 
It has been observed at intervals from Montgomery to Hat- 
field, 4 distance of twenty miles: but it is very doubtful, 
whether it continues, uninterruptedly, the whole of that ex- 
tent; indeed, from what I have observed of other lead veins 
in the vicinity, I have sometimes been disposed to ques- 
tian, whether the veins observed at many of these intervals, _ 
inch, toa foot in diameter. At the depth above mentioned, 
the water became so abundant, that it was thought advisable 
to abandon a perpendicular exploration, and to descend to 
ihe foot of a hill on the east, nearly eighty rods from the vein, 
and attempt a horizontal drift, or adit, and ever since its 
commencement, seven or eight years ago, the working of 
the vein has ceased. This drift is now carried into the hill, 
rewarded for the great expence they have incurred, but, al- 
so, that many a rich specimen will be found to ornament the
