  The

  doubled 
  within 
  the

  three 
  years. 
  

   It 
  is 
  to 
  be 
  expected 
  from 
  the 
  present 
  general 
  conditions 
  of 
  busi- 
  

   ness 
  that 
  there 
  will 
  be 
  little

  include 
  only 
  the 
  

   quantities

  some 
  crude 
  

   gypsum 
  is 
  imported 
  each 
  year 
  from 
  Canada 
  and 
  calcined 
  in 
  local 
  

   plants. 
  The
