Economical Geology. 



chusetts, and Vermont ; although, as the beds lie upon the clay that 

 is deposited above all the solid rocks, they have no necessary connec- 

 tion with the limestone. 



Beds in Lenox. 



These have been explored to some extent in the village, and a mile 

 or two farther west. The ore is good, I believe, but at present it is 

 not used. 



Beds in Richmond. 



These appear to be numerous and extensive. They are wrought 

 to some extent. 



Bed in West Stockbridge. 



This furnishes good ore, and is explored more extensively than any 

 other I saw in the county. The farmer who owns it receives thirty 

 seven cents and a half per ton, of those who dig it. 



In Salisbury, Ct. 



The beds here are very large, and have been extensively explored. 

 The Salisbury iron is known far and wide. 



In Bennington, Vt. 



Here also the same ore is dug to some extent ; and these beds 

 seem to deserve a notice, because they lie, like those in Salisbury, 

 upon the borders of Massachusetts. 



In all the beds of brown oxide of iron mentioned above, we find 

 the brown haematite in all its forms, the compact variety, and the 

 ochrey brown oxide, or yellow ochre. Manganese also is found in 

 them all, and at Bennington in large quantities ; although I have 

 been told, that this locality is nearly exhausted. It was of a supe- 

 rior quality. 



The red oxide of iron is found, in comparatively small quantities, 

 at the localities above mentioned. It exists, also, in other places in 

 the State, and especially at Conway, with manganese ; although it is 

 not, as yet, found in large quantities. Argillaceous oxide of iron is 

 likewise found at most of the hcematite beds above described. 



In Cranston, R. I. 

 From this place General Leach procures, as he told me, very ex-
