354 Brace on the Minerals of Litchfield. 
l, both crystallized and massive, is often found in 
Litchfield in granites. Its colors are green, greenish yel- 
low, pale yellow, and brown. Its crystals are often very per- 
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 of sienite. ~ 
Perhaps no region can be found containing more beautiful 
tremolite. All its varieties occur; the fibrous of Litchfield and 
Bethlem is very much distinguished. In Canaan, it is found con- 
taining crystals of sulphuret of iron. 1 do not speak here of 
the tremolite found in the limestone range. 
~ Common asbestus exists in Washington and New Milford. 
he 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. The crystals sometimes 
occur several inches long. 
The lamellar and slaty varieties of common hornblende are 
very common. 
Radiated actynolite of beautiful bluish green in Litchfield; 
in Canton of a brownish green. 
Steatite is common, and js quarried in Litchfield. The va- 
rieties of tale are very common, connected with steatite, cya- 
nite, and chlorite. 
Chlorite in Litchfield, is found on quartz, with talc. 
Porcelain clay in Litchfield in small quantities, and in Wash- 
ington. 
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 
in Litchfield, sulphuret of iron in mass is in great quantities;
