In Whately. 
In this town are three distinct veins, containing lead. One is about 
half a mile east of the second vein described in Williamsburgh. It 
extends a short distance into Williamsburgh, and more than a mile 
into Whately. In its whole course, but particularly at its southern 
part, it contains oxide of manganese along with galena. 
A second vein, three or four feet wide, exists in a high ridge of 
granite towards the south west part of the town. It may be traced 
along this ridge about three quarters of a mile. 
The third vein is in the north-west part of the town, extending 
some distance into Conway. Galena, in quartz, is the only ore that 
appears on the surface. The width of the vein is six or seven 
feet, and it traverses both granite and mica slate. It runs along the 
western margin of a high hill, so that if it should ever be explored, 
a lateral drift would be easily made. 
In Hatfield. 
About two miles west of the village in this town, we find a vein of 
sulphate of barytes, from one to four feet wide at the surface, run- 
ning in a north-westerly direction and containing galena. A shaft 
has been sunk in two places, from fifteen to twenty feet deep; and 
the vein was found rapidly to widen in descending. ‘The immense 
quantity of barytes found here, gives the locality a peculiar interest 
to the mineralogist. 
In Leverett. 
Although this town lies on the eastern side of Connecticut river, 
yet the granite and mica slate, occurring there, exactly resemble the 
same rocks found on the west side of the river; and there can be no 
doubt that both belong to the same general formation. Two veins, 
the ore being chiefly galena, are found of precisely the same charac- 
ter as those on the opposite side of the river. That in the south east 
part of the town is in granite, not more than a foot or two wide at 
the surface, and the gangue is sulphate of barytes. The other is a 
mile and a half to the north of the first; the gangue is quartz, and 
there is almost an equal quantity of galena and pyritous copper ; 
blende also occurs in small quantities. This vein is several feet 
wide, and runs through granite and mica slate. Both this and the 
one first mentioned, have been explored to the depth of a few feet. 
It is impossible to form any confident opinion as to the probable 
-quantity of lead, which is contained in the several veins which have
