  places 
  by 
  a 
  moderately 
  fine 
  sand 
  and 
  gravel, 
  cross-bedded 
  in 
  places. 
  

   The 
  clay 
  varies 
  from 
  6 
  to 
  50 
  feet 
  in 
  thickness. 
  It 
  extends 
  in 
  places 
  

   to 
  an 
  altitude 
  of 
  90 
  feet, 
  as 
  at 
  McConnell 
  & 
  O^Brien's 
  bank, 
  

   while 
  at 
  others, 
  as 
  McGuire's 
  bank, 
  it 
  only 
  reaches 
  a 
  hight 
  of 
  6 
  

   feet 
  above 
  mean 
  tide. 
  At 
  the 
  latter 
  place 
  the 
  clay 
  is 
  overlain 
  by 
  10 
  

   feet 
  of 
  sand 
  and 
  coarse 
  gravel 
  and 
  has 
  been 
  excavated 
  to 
  10 
  feet 
  

   below 
  mean 
  tide. 
  

  

  A 
  partial 
  analysis 
  of 
  the 
  buff 
  clay 
  from 
  McConnell 
  & 
  O'Brien's 
  

   clay 
  bank 
  at 
  Yerplanck

  King 
  & 
  Lynch's 
  yard 
  is 
  situated 
  on 
  G-eorge 
  point 
  near 
  Mon- 
  

   trose. 
  The 
  bank 
  is 
  about 
  700 
  feet 
  distant, 
  and 
  the 
  clay 
  is 
  hauled 
  

   in 
  cars 
  drawn 
  by 
  horses. 
  At 
  most 
  of 
  the 
  yards 
  the 
  haulage 
  is 
  

   down 
  grade. 
  Fisher's 
  clay 
  bank 
  at 
  Crugers 
  is 
  overlain 
  by 
  2 
  feet 
  

   of 
  loam. 
  This 
  is 
  used 
  to 
  supply 
  part 
  of 
  the 
  tempering 
  material 
  

   and 
  the 
  rest 
  is 
  obtained 
  from 
  Jonespoint. 
  At 
  the 
  yards 
  on 
  Yer- 
  

   planck 
  point 
  horse 
  power 
  is 
  chiefly 
  used 
  to 
  operate 
  the 
  machinery. 
  

   Most 
  of 
  the 
  yards 
  at 
  this 
  locality 
  obtain 
  their 
  clay 
  from 
  the 
  pits 
  of 
  

   the 
  Hudson 
  river 
  brick 
  co. 
  This 
  clay 
  bank 
  is 
  worked 
  in 
  benches^ 
  

   The 
  haulage 
  distance 
  is 
  about 
  one 
  half 
  a 
  mile. 
  It 
  is 
  done 
  either 
  

   in 
  carts 
  or 
  in 
  cars 
  run 
  on 
  tracks 
  and 
  drawn 
  by 
  horses. 
  

  

  Along 
  the 
  isew 
  York 
  Central 
  railroad 
  a 
  short 
  distance 
  south 
  of 
  

   Montrose 
  station 
  are 
  the 
  yards 
  of 
  C. 
  Hyatt 
  and 
  J. 
  Morton. 
  Mr 
  

   Morton 
  also 
  has 
  a 
  covered 
  yard 
  on 
  Yerplanck 
  point 
  where 
  front 
  

   brick 
  are 
  made. 
  Their 
  banks 
  are 
  practically 
  a 
  continuation 
  of 
  

   each 
  other. 
  The 
  clay 
  is 
  both 
  blue 
  and 
  yellow 
  and 
  is 
  overlain 
  by 
  

   several 
  feet 
  of 
  coarse 
  sand. 
  Hyatt 
  uses 
  steam 
  power 
  and 
  Morton
