^46 Localities of Minerals. 



fourths of an inch in diameter, in the western part of Gran- 

 by, in a field a few rods north east of a blacksmith's shop, 

 occupied by Mr. Tracy Cannon. In some of the rocks 

 they form geodes of considerable size. Of these I obtained 

 some specimens which, when placed near the blaze of 

 a candle, exhibit a remarkably brilliant and beautiful ap- 

 pearance. 



2. Black Tourmaline. Of this mineral there is a remark- 

 able localitity in Barkhampstead, on the farm of Wilham 

 Taylor, Esq. The rock in which it is found is a fine-grain- 

 ed granite, penetrated by a vein of quartz nine or ten inches 

 wide. From this vein elegant specimens may easily be ob- 

 tained by means of a hammer or sledge. I succeeded in 

 getting one crystal, which is more than an inch in diameter 

 and five inches long. The rock is situated about fifty rods 

 W. N. W. of Mr. Taylor's house, and about the same 

 distance east of the turnpike road leading from Hartford to 

 Albany. 



3. Garnets of twenty-four sides, of the size of a musket- 

 ball, are found in great abundance on what is called West- 

 Hill, in the town of New-Hartford. The spot which I visit- 

 ed is on the farm of Mr. Silvester Seymour, about forty rods 

 west of the house occupied by Mr. Michael Olmstead. The 

 rocks and stones in which they occur are easily broken in 

 pieces, and the visitor will be detained but a few minutes in 

 obtaining as many specimens as he wants.

1. Calcareous Spar, beautifully crystallized, at Chester. 

 Emmons. 



2. Stalactites and Stalagmites, at the cave lately discov- 

 ered in Lanesborough. When this cave was discovered, it 

 was filled with stalactites and stalagmites of the most fantas- 

 tic appearance, some of which were shown at a house near 

 the cave. The most curious have been removed by the 

 visitors ; I obtained, however, a plentiful supply of the less 

 interesting ones. There are several turnings or windings in 

 this cave. Breathing is free here and lamps burn perfectly 

 well.*
