  surface 
  of 
  the 
  road 
  injuring 
  the 
  horses 
  and 
  making 
  pleasure 
  

   driving 
  impossible. 
  

  

  Limestone 
  from 
  its 
  softness 
  and 
  greater 
  binding 
  power 
  is 
  more 
  

   easily 
  rolled 
  into 
  an 
  even 
  surface 
  under 
  the 
  wheels 
  of 
  vehicles, 
  

   and 
  while 
  not 
  having 
  the 
  durability 
  to 
  support 
  heavy 
  traffic 
  for 
  

   a 
  long 
  time, 
  can 
  be 
  cheaply 
  renewed 
  if 
  the 
  source 
  of 
  supply 
  is 
  not 
  

   far 
  distant. 
  This 
  fact 
  has 
  been 
  recognized 
  for 
  a 
  long 
  time 
  at 
  

   points 
  within 
  easy 
  reach 
  of 
  the 
  limestone 
  quarries. 
  In 
  Onon- 
  

   daga 
  county 
  at 
  many 
  points 
  a 
  portable 
  crusher 
  has 
  been 
  used 
  

   to 
  crush 
  the 
  blocks 
  for 
  road 
  metal 
  from 
  the 
  limestone 
  fences 
  

   which 
  are 
  cheerfully 
  donated 
  by 
  the 
  residents 
  for 
  the 
  improve- 
  

   ment 
  of 
  the 
  roads. 
  There 
  are 
  many 
  other 
  counties 
  in 
  which 
  this 
  

   might 
  be 
  done 
  as 
  may 
  be 
  seen 
  from 
  the 
  geologic 
  map. 
  In 
  most 
  

   of 
  these 
  areas 
  limestone 
  will 
  be 
  found 
  in 
  the 
  fences 
  and 
  may 
  be 
  

   crushed 
  for 
  road 
  metal 
  at 
  small 
  expense. 
  

  

  Many 
  of 
  the 
  local 
  stone 
  quarries, 
  which 
  are 
  scattered 
  over 
  the 
  

   state, 
  sell 
  for 
  road 
  metal 
  the 
  rock 
  obtained 
  in 
  stripping 
  off 
  the 
  

   upper 
  layers 
  from 
  their 
  quarries. 
  

  

  A 
  few 
  large 
  quarries 
  are 
  operated 
  for 
  road 
  metal 
  alone 
  and 
  

   deserve 
  special 
  mention. 
  

  

  Many 
  tons 
  of 
  material 
  are 
  quarried 
  annually 
  from 
  the 
  Pali- 
  

   sades 
  range 
  near 
  Piermont. 
  The 
  material, 
  which 
  is 
  exceedingly 
  

   tough, 
  is 
  either 
  dressed 
  for 
  paving 
  blocks 
  or 
  crushed 
  for 
  road 
  

   metal. 
  

  

  Farther 
  up 
  the 
  Hudson 
  river 
  the 
  limestone 
  quarries 
  of 
  Tomkins 
  

   Cove 
  have 
  been 
  in 
  operation 
  for 
  a 
  number 
  of 
  years 
  and 
  supply 
  

   large 
  quantities 
  of 
  rock 
  for 
  macadam. 
  Other 
  quarries 
  are 
  at 
  

   South 
  Bethlehem, 
  Albany 
  county, 
  Howe's 
  Oave, 
  Schoharie 
  county 
  

   and 
  there 
  are 
  several 
  near 
  Syracuse 
  and 
  Buffalo. 
  This 
  magnesian 
  

   limestone 
  is 
  one 
  of 
  the 
  best 
  materials 
  used. 
  It 
  is 
  hard, 
  packs 
  

   easily 
  and 
  makes 
  a 
  good 
  surface, 
  but 
  the 
  cost 
  of 
  maintenance 
  is 
  

   considerable. 
  

  

  At 
  lona 
  Island 
  a 
  granite 
  is 
  quarried 
  and 
  crushed 
  to 
  five 
  or 
  six 
  

   different 
  sizes 
  for 
  road 
  metal 
  and 
  concrete. 
  The 
  fine 
  residue 
  or 
  

   dust 
  is 
  sold 
  for 
  polishing.
