  tiiat 
  witli 
  very 
  little 
  labor 
  in 
  one 
  sinj^lc 
  

   and 
  sliori 
  operation, 
  the 
  mineral 
  can 
  he 
  exliausfed. 
  There 
  are 
  no 
  rich 
  residues 
  

   left 
  to 
  be 
  worked 
  over 
  nor 
  liquors 
  to 
  be 
  concentrated, 
  which 
  makes 
  the 
  lixiviat- 
  

   in^r 
  process 
  so 
  complicated. 
  Besides, 
  the 
  boracic 
  acid, 
  and 
  particularly 
  the 
  bor- 
  

   acic 
  acid 
  glass, 
  can 
  bear 
  the 
  high 
  co.st 
  of 
  transportation 
  from 
  the 
  borax 
  marshes 
  

   much 
  better 
  than 
  the 
  borax 
  or 
  the 
  borate 
  of 
  lime. 
  To 
  bring 
  one 
  pound

  six 
  to 
  seven 
  cents. 
  To 
  transport 
  tlie 
  molten 
  boracic 
  acid, 
  which 
  gives 
  

   three 
  pounds 
  of 
  borax 
  r.early, 
  would 
  reduce 
  the 
  cost 
  for 
  one
