There are also various other more highly modified forms at the localities in this town, but 
they are seldom sufficiently perfect for measurement. 
Putnam County. There are several localities of hornblende in this county, but well 
defined crystals are seldom found. 
Hornblende, in the form of the primary with the acute lateral edges replaced by tangent 
planes (Fig. 240), occurs in Phillipstown, of a grey colour; and tremolite of a white and 
bluish colour, at Hustis’ farm in this town, and also at Coldspring. 
Hornblende, in long four and six-sided prisms without perfect terminations, occurs abun¬ 
dantly in a decomposing serpentine at Brown’s quarry, three miles northwest of the village of 
Carmel. 
At the same locality, actynolite, of various shades of grey and green, having a good deal 
of lustre, is found in veins in the serpentine. The fibres are bent, curved and interlaced, and 
sometimes pass almost into asbestus. 
The same variety is found in the town of Kent, about two miles northeast of Carmel. 
At the Phillips iron mine, actynolite, green and black, is sometimes found coating the ore. 
Lamellar hornblende, having a high lustre, and exhibiting various shades of green, brown 
and black, is found associated with magnetic iron ore in the town of Southeast, about three 
miles southeast of the village of Carmel; and the same mineral, of a dark green or black 
colour, associated with epidote and other minerals, is found in the same town, a short distance 
from the preceding. 
Tremolite of a white and bluish white colour, both bladed and fibrous, is abundant in the 
dolomite in the vicinity of the village of Patterson. Knapp’s quarry affords the best speci¬ 
mens. They are quite similar to those found in the same rock in Dutchess, Westchester and 
New-York. 
Asbestus, often reduced to silky fibres of a white colour, is frequently found in the same 
rock in the vicinity of Patterson. It is sometimes associated with loose crystals of pyroxene 
and calcareous spar, the whole having been originally imbedded in the dolomite, which has
