  In 
  the 
  winter 
  only 
  a 
  very 
  few 
  are 
  employed 
  in 
  hauling 
  bricks, 
  care 
  

   of 
  buildings, 
  etc. 
  In 
  the 
  blue 
  stone 
  industry 
  the 
  greater 
  number 
  

   of 
  the 
  men 
  are 
  employed 
  during 
  the 
  summer, 
  thus 
  working 
  only 
  

   a 
  part 
  of 
  the 
  year. 
  Many 
  farmers, 
  who 
  occasionally 
  quarry 
  blue 
  

   stone, 
  work 
  only 
  a 
  few 
  weeks 
  or 
  months 
  out 
  of 
  the 
  year. 
  The 
  

   cement 
  industry, 
  however, 
  keeps 
  its 
  men 
  pretty 
  constantly 
  

   employed. 
  The 
  scattering 
  industries, 
  lime 
  burning, 
  etc., 
  are 
  

   irregular.

  CEMENT. 
  

  

  In 
  the 
  manufacture 
  of 
  natural 
  cement 
  Ulster 
  county 
  leads 
  all 
  

   other 
  localities, 
  as

   in 
  1891 
  7,451,535 
  

  

  It 
  will 
  thus 
  be 
  seen 
  that 
  Ulster 
  county 
  produced 
  nearly 
  thirty- 
  

   eight 
  per 
  cent 
  of 
  the 
  natural 
  cement 
  made 
  in 
  the 
  United 
  States 
  

   in 
  1891. 
  

  

  In 
  accounting 
  for 
  this 
  great 
  industry 
  it 
  is 
  not 
  sufficient 
  to 
  say 
  

   that 
  the 
  natural 
  composition 
  of 
  the 
  hydraulic 
  limestone 
  of 
  this 
  

   county 
  is 
  superior 
  to 
  all 
  other 
  localities; 
  or 
  that 
  the 
  greater 
  

   thickness 
  of 
  the 
  beds, 
  or 
  the 
  position 
  in 
  which 
  they 
  lie, 
  render 
  

   the 
  mining 
  of 
  the 
  rock 
  much 
  cheaper.
