pocket of emeralds, hiddenite, quartz, etc., on the Osborn 
Lackey land in Alexander County, N. C. This new discovery 
is distant about one-fifth of a mile northwest from the mine of 
the Emerald and Hiddenite Mining Company, and joins the 
land formerly known as the Lyon’s property. About fifty 
crystals of emerald, 2cm. to 7 cm. long and from 2 mm. to 
8 mm. in diameter, were found. They were all transparent 
but of pale color and but one of the crystals was large and pure 
enough to be cut into gems, The Hiddenites found were very 
_ inferior and of very pale color. The curious rough edges and 
pseudo-horizontal striations were noticed on nearly all of the 
crystals of emerald, these markings being peculiar to the beryls 
of the region. Only the planes /, 7-2 and O were found. 
The particular interest attached to this occurrence is the fact of - 
the locality being somewhat distant from the old one and for 
this reason it is encouragement for future work.
