Silver Mine. T3nT£e bank of the Con- 

 necticut, three miles -S. E. of the college. It 

 was worked by the colony for lead from 1775 

 to 1778, with the hope that it could be ob- 

 tained in sufficient quantities for military 

 purposes. It is said that the bullets- used in 

 the battle of Saratoga were made in a small 

 red house still standing -near the mine. The 

 vein which, was worked extended north-

 very rich in places. It has since been used

Cobalt Mine. At. the foot of Great Hill, 

 in the town of Chatham, seven miles S. E. 

 of the college. It maybe reached either by 

 land or by rowing to Middle Haddain, six

 This mine was opened in 3 762, by a com-
