504 GEOLOGY OF OLD HAMPSHIEB COUNTY, MASS. 



then, in my freshman year, and rowing the length of the adit. The Manhan 

 Silver-Lead Company was formed, which erected extensive buildings and 

 installed expensive machinery. I have been informed that the enterprise 

 failed because of the fall in the price of lead at the close of the war, and 

 that the machinery, costing about $60,000, was sold to the Chester Emery 

 Company for about $17,000. 



The vein produced lead with about 12 i ounces of silver per ton from 

 galena. Sphalerite, chalcopyi'ite, pyrite, and bornite occun-ed more rarely; 

 barite and quartz in abundant crystals was the gangue. As decomposition 

 products, malachite appeared with wulfeuite, cerussite, and anglesite, and 

 the linest pyromorphite occurred. Pseudomorphs after calcite and fluorite 

 indicated the former more abundant presence of these gangue minerals. 



The most interesting article that has been published on the lead veins 

 of Hampshire was by a wholly self-taught man, Mr A. Nash, and this seems 

 to have been his only essay in authorship. Professor Shepard, who then 

 did editorial work on the American Journal of Science, told me that it took 

 much editing to make the paper intelligible. Much of what follows comes 

 from that paper.^ 



Whateli/. — This vein is in the southwest part of the town, on the 

 summit of a high mountain of granite. The vein is 3 to 4 feet wide; 

 considerable galena occurs in a quartz gangue; the range and vein strike 

 northeast. (Nash.) I have searched for this without success. 



miateli/. — In the northwest part of the town. The vein runs north 

 and south. It has been traced 100 yards to the edge of Conway. The 

 ends of the vein are in mica- schist; the middle Is in granite; 6 to 7 feet 

 wide. The gangue is quartz; the ore, galena only. (Hitchcock.-) Shows 

 graphitic slickensides; crushed veins with quartz, calcite, and green fluor. 



Conway. — Southeast part, 3 miles from meetinghouse, and southeast 

 of the manganese vein. It contains quartz and galena. (Nash.) Maybe 

 the same as the last. 



Chesterfield. — A copper mine is put down on Nash's map east of the 

 Lily Pond Brook, but not mentioned in the text. 



Goshen. — Sixty rods east of Congregational meetinghouse; galena in 

 crystallized masses of quartz on the ground; no vein seen. (Nash.)
