The specific gravity is 3°64 and was determined upon 
several different samples. Pleochroisim 1s very strong. 
Iron and chromium were very carefully tested for, but 
no-trace of either was observed in the analysis, Which 
showed only the presence of alumina and silica. 
Crystallized cyanite is usually in long bladed crystals 
without terminations, the best crystals having been found 
at St. Gothard in Switzerland and on Mt. Greiner in 
Bryerolii «>. Lhese crystals of a blue and blueish white 
color, are often transparent but are seldom over a few 
millimeters wide. i 
.Phis new occurrence of the cvanite is not only of inter- 
est on account of the deep green color of the mineral but 
also on.account of the exceptional size and development 
of the crystals. 
“Pale green cyanite has been obtained from a number of 
localities and it has also been found in the v icinity of the 
ereen cyanite locality on the farm of Isaac Enelish of 
Spruce Pine, Mitchell Co., imbedded in an undecomposed 
mica schist. Another occurrence that is worthy of note 
is that of Graves Mt., Georgia. At this locality thin 
small plates of the pale green cyanite are associated with 
well crystallized rutile.
