DESCRIPTIVE MINERALOGY. 



The variety asbestus is found in fibres from half to three-quarters of an inch in length, 

 near the Greenwood furnace. The same mineral occurs in narrow veins, but of a high silky 

 lustre, at the Stirling, Forshee and O'Neil iron mines. It is found traversing the ore, as well 

 as the accompanying rock. The so called hard asbestus, which is found at the Wilks mine 

 in Monroe, and in various parts of the town of Warwick, is probably serpentine. 



In the town of Montgomery, the variety byssolite, which is probably a disintegrated horn- 

 blende, is found ; and the same mineral, with very short fibres, occurs on massive hornblende 

 at what is called Bedford's gold mine, in the town of Newburgh. 



The town of Warwick is most rich in localities of this mineral. 



At the southern base of Mount Eve, two and a half miles north of Edenville, crystallized 

 hornblende is disseminated through an aggregate of limestone and scapolite. The crystals 

 are bluish, greyish green, and deep greenish black. Besides the primary, several other forms 

 have been found at this place. 



About a mile north of Edenville is another locality, at which the crystals are of a hair- 

 brown or grey color, associated with sphene, mica and chondrodite, in white limestone. They 

 vary in size from very small to an inch in diameter. From the peculiarity of its colour, it 

 has sometimes been called Edenite. A similar variety is found a quarter of a mile south of 

 the preceding, in very large crystals, often six inches long and four inches in diameter. Near 

 this locality, tremolite and hornblende, crystallized and massive, are also found. They are 

 all green of various shades. The crystals are from semi-transparent to transparent. 



In the same vicinity, on the farm of B. Hopkins, there is an abundance of grey massive 

 hornblende, containing veins of arsenical iron and other minerals. 



The crystalline forms observed at the localities near the village of Amity, are, the primary 

 (Fig. 223), triunitaire of Haiiy (Fig. 224), accelere of Haiiy (Fig. 225), dodecaedre of 

 Haiiy (Fig. 226) ; and also.
