Bolivia  may  rightly  be  called  the  mineral
storehouse  of  the  world,  for  locked  within  the
heart  of  her  many  mountains  are  untold  riches,
the  tons  which  she  has  contributed  to  the  universe ­
  being  microscopic  in  proportion  to  what
remains.  Her  inexhaustible  dried  lakes  of
borax  and  salt,  glistening  like  snow  in  the  pure
air  of  the  high  elevation,  have  been  scraped
for  centuries  without  apparently  reducing
their  supply.  There  are  many  rich  deposits
of  gold,  silver,  copper,  tin,  antimony,  bismuth,
borax,  zinc,  wolfram  and  coal.
In  the  production  of  tin,  Bolivia  ranks  second, ­
  the  chief  producer  being  the  Malay  Peninsula. ­
  Tin  forms  about  70  per  cent,  of  the
total  export  of  Bolivia,  amounting  in  value
to  over  $23,000,000,  Great  Britain  taking
about  90  per  cent,  of  the  output  of  the  mines
and  selling  it  to  the  other  nations  of  the  world.
There  are  yet  enormous  unworked  deposits
of  this  metal  in  this  land.
Bolivia  is  one  of  the  largest  bismuth  producing ­
  countries  of  the  world  and  the  third  in
the  production  of  copper,  and  is  rich  in  anti-
