GOsths's dying cry for more light
has been echoed around the world until
cities now blaze at night with the glory
% the MONDAY sun. and this has been
made possible by some Of these rare
metals. 30 too automobiles owe their
present perfection in part to the Once
rare metals that temper and tougher
steel. In other industries also these
metals play an important part.
Until "A comparatively short time ago
these rare metals were lest IN the dump
heap al the mines Icing deemed not
only valueless hut actually detrimental
to the concentration of the ore which
was considered of value. In Boulder

throw away what they called black jack.

mining
In Cornwall. England. the miners found
tungsten ore. but called II mock lead
because OF its high specific gravity. and
they too left It in the dump Upon
learning the value vt the stun they are
working over the refiis" heaps to recover
the valuable tungstcH.
