- Fluor Spar, crystallized and massive in quartz, ‘tra- 
soniog granite about two miles east of Cooke’s tavern in 
Cumberland, colour white, smoky, purple, and violet. When 
placed on hot coals, it phosphoresces with an intense eme- 
rald-green light—a quantity might be stein at this place 
= but fittl: trouble.

portion of mica, crystals of one and a quarter inches in 
diameter have been obtained from this place, they are from 
ihe veins on the surface and are seldom regularly termin- 
ated—were the rocks in the neighbourhood blasted, it is 
probable that large and perfect crystals might be procured.
