in which rubellite crystals are found entirely embedded in the 
lepidolite, the rubellite appearing as pink radiations in dark 
gangue of lilac-colored lepidolite. 
Those who have been permitted to inspect the workings have 
marveled at the wonder-hand of Nature. From the rocky slope 
one plunges into the yawning mouth of a tunnel that zig zags 
its way to the ledge that lies between walls of pegmatyte, or 
muscovite-granite and quartz. In places, this quartz is deeply 
stained by bismuth and decomposed rubellite. 
The first stope, broken in along the contact of the ledge and 
pegmatyte, is like a grotto in Aladdin’s cave. Embedded in 
the walls on one side the rubellite is found in great radiations, 
like clusters of pink chrysanthemums on a background of lilac 
that shades to deep blue. On the other side the milky white 
“pegmatyte, with large brilliant scales of mica, gives an attrac- 
tive setting for the jet black crystals of tourmaline that are 
also found in radiations in this rock. The light of a single 
eandle is caught up by the millions of scales and reflected over 
and over until the effect is dazzling. 
This stope has been named by the workmen the ‘‘Bridal 
Chamber’’. 
This deposit has attracted to it scientists from many corners 
of the world, German chemists being especially interested by 
reason of its lithia contents, as at present the principal supply 
of tablets is manufactured in that country. 
Less than half a mile northeast of this deposit, across the 
canyon and near the summit of the western slope, is the famous 
Kunzite mine. Here less than three years ago was unearthed 
a most remarkable deposit of unaltered lilac-colored spod- 
umene. These crystals were beautiful in their color tones, 
varying from deep rosy lilac to pale or almost color- 
less—a striking contrast to the rich deep pink-purple found at 
a greater depth. 
This is the only known lilac-colored spodumene deposit in 
the world, and is most valuable for its beauty as a gem. Crys- 
tals to the value of many thousands of dollars have been taken 
from the ledge, and within the past thirty days several new 
pockets containing many valuable crystals have been opened. 
Hiddenite, or lithia emerald, is a variety of spodumene vary- 
ing in color from a yellow green to a deep emerald green tinged 
with yellow. Like Kunzite this is at present known to but one 
locality (Stony Point in North Carolina), but knowing ones 
predict that development will also expose this valuable gem 
erystal at the Pala mines. 
Kunzite is found in metamorphic rocks, generally gneiss or 
mica schist. The rock is a coarse decomposed granite, the 
feldspar much kaolinized and reduced to red dirt. The crystals
