  From 
  Clinton 
  iron 
  ore.

  From 
  Chemung 
  shale, 
  at 
  Randolph.

  From 
  Catskill 
  shale 
  at 
  Roxbury 
  and 
  Oneonta. 
  

  

  This 
  material 
  is 
  produced 
  as 
  a 
  by-product 
  in 
  several 
  industries. 
  

   For 
  instance 
  near 
  Whitehall 
  red 
  and 
  green 
  mineral 
  paint 
  are 
  

   produced 
  by 
  grinding 
  up 
  the 
  refuse 
  of 
  the 
  slate 
  mills. 
  At 
  Clin- 
  

   ton, 
  Oneida 
  county, 
  paint 
  is 
  manufactured 
  from 
  the 
  Clinton 
  iron 
  

   ore. 
  At 
  Randolph 
  in 
  Cattaraugus 
  county, 
  paint 
  is 
  made 
  from 
  

   red 
  shales 
  of 
  the 
  Chemung 
  group. 
  At 
  Roxbury, 
  Delaware 
  county, 
  

   paint 
  is 
  made 
  from 
  red 
  Catskill 
  shales 
  and 
  at 
  Oneonta 
  a 
  similar 
  

   pigment 
  has 
  been 
  made.

  This 
  material 
  is 
  found 
  in 
  many 
  places 
  throughout 
  the 
  state. 
  

   Dutchess, 
  Columbia, 
  Orange, 
  Ulster, 
  Greene 
  and 
  Albany 
  counties 
  

   have 
  many 
  small 
  deposits; 
  in 
  central 
  and 
  western 
  New 
  York 
  

   there 
  are 
  large 
  deposits 
  in 
  Onondaga 
  and 
  Madison 
  counties, 
  

   particularly 
  in 
  the 
  Cowaselon 
  swamp 
  ; 
  it 
  is 
  also 
  f 
  o-und 
  in 
  Cayuga, 
  

   Wayne, 
  Seneca, 
  Ontario, 
  Monroe, 
  Genesee 
  and 
  Niagara 
  counties. 
  

  

  It 
  is 
  a 
  deposit 
  formed 
  in 
  standing 
  water 
  and 
  consists 
  chiefly 
  of 
  

   carbonate 
  of 
  lime. 
  It 
  is 
  largely 
  used 
  as 
  a 
  fertilizer, 
  but 
  is 
  also 
  

   employed 
  in 
  the 
  manufacture 
  of 
  Portland 
  cement 
  as 
  at 
  Warners, 
  

   Onondaga 
  county, 
  by 
  the 
  Empire 
  Portland 
  Cement 
  Co., 
  at 
  

   Montezuma 
  and 
  at 
  Wayland, 
  Steuben 
  county, 
  by 
  Millen 
  & 
  Co. 
  

  

  Millstones 
  

  

  Millstones 
  for 
  grinding 
  paint, 
  feed, 
  cement 
  and 
  other 
  purposes 
  

   are 
  quarrjed 
  from 
  the 
  Oneida 
  conglomerate 
  in 
  Ulster 
  county 
  in 
  

   the 
  town 
  of 
  Rochester 
  at 
  Accord, 
  Granite 
  and 
  Kyserike 
  and 
  in 
  

   Wawarsing 
  at 
  Kerhonkson. 
  

  

  Salt 
  

  

  The 
  salt 
  industry 
  of 
  New 
  York 
  is 
  of 
  great 
  importance. 
  Origin- 
  

   ally 
  Syracuse 
  was 
  the 
  center 
  of 
  this 
  industry, 
  but 
  since 
  the 
  dis- 
  

   covery 
  of 
  rock 
  salt 
  in 
  and 
  near 
  the 
  Genesee 
  valley 
  where 
  richer 
  

   brines 
  can 
  be 
  obtained 
  than 
  at 
  Syracuse, 
  the 
  center 
  of 
  the 
  industry
