  The 
  main 
  product 
  of 
  Washington 
  county 
  is 
  red 
  slate. 
  This 
  is 
  

   the 
  most 
  vahiable 
  variety 
  of 
  roofing 
  slate. 
  The 
  color 
  is 
  an 
  attractive 
  

   shade 
  of 
  red 
  or 
  reddish 
  brown 
  which 
  does 
  not 
  change 
  on 
  exposure. 
  

   Red 
  slate 
  brings 
  an 
  average 
  of 
  $7 
  or 
  $8 
  a 
  square 
  and 
  is 
  shipped 
  all 
  

   over 
  the 
  country 
  and 
  even 
  abroad 
  for 
  use 
  on 
  fine 
  buildings. 
  The 
  

   principal 
  quarries 
  are 
  near 
  Granville 
  and 
  North 
  Granville 
  on 
  the 
  

   north 
  end 
  of 
  the 
  slate 
  belt. 
  Sea 
  green, 
  purple 
  and 
  variegated 
  

   slates 
  are 
  obtained 
  around 
  Middle 
  Granville, 
  Salem 
  and 
  Shushan. 
  

   The 
  red 
  and 
  green 
  varieties 
  sometimes 
  occur 
  in 
  alternating 
  beds 
  in 
  

   the 
  samcv 
  quarry. 
  Black 
  slate 
  has 
  been 
  worked 
  at 
  different 
  times 
  

   in 
  the 
  southern 
  portion 
  of 
  the 
  metamorphic 
  belt, 
  but 
  the 
  operations 
  

   apparently 
  have 
  not 
  been 
  a 
  commercial 
  success. 
  There 
  are 
  aban- 
  

   doned 
  quarries 
  at 
  Hoosick, 
  New 
  Lebanon 
  and 
  New 
  Hamburg. 
  The 
  

   quarry 
  of 
  the 
  last 
  mentioned 
  locality 
  was 
  developed 
  about 
  10 
  years 
  

   ago. 
  

  

  The 
  quantity 
  of 
  roofing 
  slate 
  made 
  in 
  1908 
  was 
  13,735 
  squares 
  

   valued 
  at 
  $111,119. 
  The 
  average 
  price 
  received 
  was 
  $8.09 
  a 
  square, 
  

   a 
  much 
  higher 
  average 
  than 
  was 
  received 
  for 
  the 
  product 
  of 
  other 
  

   slate 
  districts 
  in 
  the 
  east, 
  due 
  to 
  the 
  fact 
  that 
  most 
  of 
  the 
  output 
  

   consisted 
  of 
  red 
  slate, 
  of 
  which 
  the 
  New 
  York 
  quarries 
  have 
  a 
  natu- 
  

   ral 
  monopoly. 
  The 
  production 
  was 
  distributed 
  among 
  1 
  1 
  firms 
  and 
  

  

  individuals, 
  most 
  of 
  whom 
  operated 
  on 
  a 
  small 
  scale.

  The 
  quarrying 
  of 
  stone 
  for 
  building 
  purposes, 
  road 
  and 
  pavement 
  

   construction 
  and 
  for 
  various 
  other 
  purposes 
  is 
  one 
  of 
  the 
  most 
  wide- 
  

   spread 
  and 
  important 
  of 
  the 
  State's 
  industries, 
  furnishing 
  employ- 
  

   ment 
  to 
  4000 
  or 
  5000 
  wage-earners 
  and 
  annually 
  producing 
  about 
  

   $7,000,000 
  worth 
  of 
  stone 
  ($6,615,614 
  in 
  1908). 
  

  

  The 
  rocks 
  of 
  the 
  State, 
  ranging 
  in 
  age 
  from 
  the 
  very 
  earliest 
  

   Precambric 
  to 
  early 
  Carbonic 
  and 
  comprising 
  igneous, 
  metamorphic 
  

   and 
  stratified 
  representatives, 
  are 
  abundantly 
  able 
  to 
  supply 
  almost 
  

   every 
  type 
  of 
  rock 
  desired 
  for 
  building 
  purposes, 
  save 
  som'e 
  orna- 
  

   mental 
  stone. 
  Notwithstanding 
  the 
  large 
  amount 
  of 
  local 
  stone 
  

   used, 
  considerable 
  quantities 
  of 
  stone 
  are 
  annually 
  imported 
  into 
  

   the 
  State; 
  granites 
  from 
  New 
  England, 
  limestones 
  from 
  Indiana 
  

   and 
  sandstones 
  from 
  Ohio, 
  coming 
  from 
  large 
  centers 
  of 
  produc- 
  

   tion 
  where 
  development 
  is 
  on 
  such 
  a 
  large 
  scale 
  that 
  the 
  stone 
  can 
  

   be 
  shipped 
  into 
  the 
  State 
  at 
  a 
  price 
  almost 
  as 
  low 
  as 
  that 
  asked 
  

   for 
  local 
  material.
