Art. XIX.—New locality of the Green Turquois known as 
Chalchuite, and on the Identity of Tig vets with the Callais or 
Callaina of Pliny; by WituiaM P. B 
N this Journal,* pee 1858, I directed attention to the 
occurrence in New Mexico of a green turquois highly prized 
as a gem by the loaseae and known as  Chal-che-we-te, “ 
Grande has made the Cerillos eee in which the gem 
occurs, much more accessible than it was, and the ancient mine 
as been re- opened and worked to some file a by Eastern 
capitalists, as made known by ee sil Silliman.t The stone 
is in consequence more abundant than before, and at Wallace 
Station on the railway very i specimens can frequently be 
obtained of the Pueblo India 
T have reonNly visited another locality where chalchuite 
occurs and was mined by the ancients. This is in Cochise 
County, ee about twenty niles from Tombstone, in an 
outlying ridge or spur of the Dragoon Mountains and not far 
from the stronghold of the Apache chief, Cochise, so long the 
terror of that region. This elevation is now known as the 
“Turquois Mountain,” and as there are several deposits of 
argentiferous ores near it, a mining district has been formed 
called the “'Turquois District.” 
At the turquois locality there are two or more ancient excava- 
tions upon the south face of the mountain, and large piles of 
waste or debris thrown out are overgrown with century plants, 
yuceas and Cactacew. It has not been worked for a long time 
and probably never by the Apaches. The excavations are not 
as extensive as at Los Cerillos, and it is more difficult to find 
spenineng of the mineral. It is evidently much less abundant 
at the New Mexican locality. Hnough of the gem was 
obtained. however, by searching in the waste heaps, to show 
that it is identical in. its appearance with the New Mexican 
chalehuite. The rock is also similar and the chalchuite occurs 
in seams and rene rarely more than an eighth or a quarter 
of an inch in thickness. 
The color is light apple-green and rey green, prooisaly that
