356 DESCRIPTIVE MINERALOGY. 



Putnam County. Epidote has been found near Coldspring, in this county. There is a 

 locahty in the town of Southeast, about two miles south of the village of Carmel, where both 

 the massive and crystallized varieties have been obtained. The crystals are translucent, of a 

 beautiful green colour, and from a quarter to three quarters of an inch in length. They arc 

 usually six-sided prisms, but the terminations are seldom perfect. The associates are horn- 

 blende, garnet, etc. 



Rockland County. This mineral is found in small granular masses, associated with feld- 

 spar and actynolite, at Montaigne's marble quarry, two and a half miles west of Grassy 

 point. 



Saratoga County. Epidote has been credited to the town of Moreau. 



Warren County. The common massive variety is found in gneiss at Sabbath Day point 

 on Lake George. 



Washington County. Epidote occurs in small but imperfect translucent crystals of a yel- 

 lowish colour, on the lianks of Lake George in the town of Putnam, two miles south of 

 Ale.tandria. 



Westchester County. Near West-Farms, it is met with in granular masses and in 

 crystals. 



In Vermont, zoizite occurs at Montpelier and Wardsborough ; in Massachusetts, at Goshen 

 and Williamsburgh ; and in Connecticut, at Milford. Fine crystals of epidote occur at Had- 

 dam in Connecticut. 



TOURMALINE. 



(Said to be a corruption of the Ceylon name for this mineral.)

Occurs regularly crystallized ; also massive and disseminated. 

 Primary form an obtuse rhombohcdron. Fig. 356. P on P 133'^ 

 26'. It is usually found in prisms of three, six, nine and twelve 

 sides, and terminated by very irregular summits. Cleavage diffi- 

 cult. Fracture uneven and imperfect. Lustre vitreous. From 

 transparent to opaque. Brittle and easily frangible. Hardness 

 from 7.0 to 7.5. Specific gravity from 3.00 to 3.42. Before 

 the blowpipe, the black variety intumesces and becomes a black scoriaceous mass ; the green 

 variety intumesces, but does not fuse. With borax, it fuses into a transparent glass. 



Tourmahne possesses the property of exhibiting different colours, according as it is viewed 

 parallel or perpendicular to the axis of its crystals, and it is almost invariably less transpa- 

 rent in the first of these directions than in the last. It becomes electric when heated ; and 

 according to Haiiy, the termination which presents the greatest number of planes always 

 exhibits the positive or vitreous electricity, while that which consists of the smaller number
