here ; and the vein was formerly explored to a considerable depth, 

 It is several feet wide. 



In West Hampton. 



This vein has been usually described as existing in Williamsburg 

 and extending into Northampton : But so far as it exhibits itself at 

 the surface' it lies wholly in West Hampton in quite the north east 

 part of the town, only a few rods from the Northampton line, and but 

 half a mile from that of Williamsburg. The gangue is quartz, and 

 the vein is several feet wide, and may be traced 30 or 40 rods. But 

 the quantity of galena is small at the surface. 



In Williamsburg. 



A vein of galena lies near the north-eastern part of this town, and 

 probably extends into Whately. It is two or three feet wide, and the 

 gangue, as in nearly every other vein of lead in this region, is quartz. 

 Manganese is found in the same gangue. 



A second vein of quartz with galena occurs in this town, a mile 

 or two north east of the one last mentioned. The quartz, however, 

 appears only in loose masses on the surface, but to such an extent, as 

 can be explained only on the supposition, that a vein exists in the rock 

 beneath the soil. Pyritous copper is found in connexion with the ga- 

 lena at this place. 



In Goshen. 



According to the statements of Mr. Alanson Nash, who has given 

 a map and description of the lead veins and mines of Hampshire 

 county, in the twelfth volume of the American Journal of Science, 

 the same indications of a galena vein appear a little west of the center 

 of Goshen, as those mentioned in respect to the third vein in Williams- 

 burg just noticed, viz. the occurrence of masses of quartz containing 

 galena. The rock in the region is mica slate and quartz. 



In Whately. 



In this town are three distinct veins containing lead. One is about 

 half a mile east of the first vein described in Williamsburgh. It ex- 

 tends 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
