colored lithia mica to that containing much feldspar, and 
amblygonite occur in masses of several tons weight. The 
amblygonite is found as a rule below the lithia deposits. 
Triplite is found in masses of several pounds weight, alman- 
dine and vermiculite occur to some extent, and about five 
pounds of sulphide of bismuth have been found in one place 
in amblygonite. This is the only metallic mineral so far 
known in this locality. 
C/ays in the Veins. At least three kinds of clay from 
the kunzite bearing pockets are recognized, known locally 
as kunzite clay, kunzite and tourmaline clay, and lithia clay. 
A physical analysis of these has been made, by specific 
gravity methods. 
Below is the average mineral composition of them :

These analyses show that the amount of feldspar and 
quartz is about the same in all — 83% to 86% — while the 
percentages of muscovite and rarer minerals vary consid- 
erably. 
The halloysite is a pink clay apparently derived from 
rubellite, for all gradations from unaltered tourmaline to 
the chalky clay can be found. An analysis of it as given 
by W. T. Schaller* is as follows :
