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, ia 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, running 

 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 quan- 

 tity 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 

 been described, except, perhaps, in regard to that in Southampton, 

 which has been explored to a considerable extent. In many instances 

 appearances at the surface are quite favorable ; but whether the veins 

 become wider, like that in Hatfield, or narrower, as they descend, 

 can be determined only by actual exploration. Of one thing, howev- 

 er, I think we may be assured, from the facts that have been stated ;
