246 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 William 
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. 1 succeeded in 
getting one crystal, which is more than an inch in diameter 
and five inches long. e 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. 
8. 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. Caleareous 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- 
lic appearance, some of which were shown at a house neat 
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 windin 
I cave. Breathing is free here and lamps burn perfectly 
well.
