3,54 Br&ce on the Minerals of Litchjieldf 



Beryl, both crystallized and massive, is often found in 

 Litchfield in granite. Its colours are green, greenish yel- 

 low, pale yellow, and brown. Its crystals are often very per- 

 fect. 



Garnets are common in all the towns of this range. 



Epidote. Very beautiful crystals of this mineral have been 

 found in Washington, associated with feldspar. They are so 

 rounded as to render it very difficult to discover their form. 

 They have a very fine lustre, and are of an olive green ; in 

 Litchfield, in crystals with hornblende, and graphic granite, 

 and in veins in sienite. 



Perhaps no region can be found containing more beautiful 

 tremolite. All its varieties occur ; the fibrous of Litchfield and 

 Bethlem is very distinguished. In Canaan, it is found contain- 

 ing crystals of sulphuret of iron. I do not speak here of the 

 tremolite found in the limestone range. 



Common asbestus exists in Washington and New Milford. 



The white augite is a mineral found in this range ; in 

 Litchfield, in six-sided prisms very much flattened, on quartz, 

 and carbonate of lime with tremolite. They sometimes occur 

 several inches long. 



The lamellar and slaty varieties of common hornblende are 

 yery common. 



Radiated actynoUte of a beautiful bluish green in Litchfield \ 

 in Canton of a brownish green. 



Steatite is common, and is quarried in Litchfield. The va- 

 rieties of talc are very common, connected with steatite, cya- 

 fiite, and chlorite. 



Chlorite in Litchfield, is found on quartz, with talc. 



Porcelain clay in Litchfield in small quantities, and in Wash- 

 ington, i 



Graphite is found in Cornwall in great quantities. Its gangue 

 is gneiss and sienite. It is lamellar, and has a metallic lustre ; 

 is easily obtained, and might be made useful. Epidote and cy- 

 anite are found with it. 



Ores are not common. Oxides of iron, and sulphuret of iron 

 are scattered over the whole range. Near Mount Prospect 

 \n Litchfield, sulphU|:et of iron in mass is in great quantities ;
