  a 
  remnant 
  of 
  a 
  terrace 
  at

  From 
  this 
  J. 
  J. 
  Jova 
  and 
  Rose 
  <fe 
  Co. 
  

   obtain 
  their 
  clay. 
  The 
  former 
  has 
  80 
  acres, 
  the 
  latter 
  40. 
  The 
  

   clay 
  is 
  mostly 
  blue 
  and 
  rises 
  to 
  a 
  hight 
  of 
  100' 
  feet 
  above 
  the 
  

   river. 
  At 
  Jova's 
  upper 
  yard 
  it 
  is 
  underlain 
  by 
  limestone 
  and 
  

   overlain 
  by 
  sand. 
  On 
  top 
  of 
  the 
  clay 
  at 
  bis 
  lower 
  yard 
  are 
  10 
  

   to 
  15 
  feet 
  of 
  sand 
  and 
  gravel. 
  

  

  A 
  well 
  was 
  sunk 
  from 
  river 
  level 
  at 
  Jova's, 
  passing 
  through 
  

   the 
  following:

  Adding 
  to 
  the 
  above 
  section 
  100 
  feet 
  of 
  clay 
  above 
  river 
  level 
  

   gives 
  us 
  a 
  total 
  thickness 
  of 
  180 
  feet 
  of 
  clay. 
  At 
  Rose 
  & 
  Co.'s 
  

   yard, 
  which 
  adjoins 
  Jova's 
  on 
  the 
  south, 
  it 
  is 
  said, 
  a 
  well 
  was 
  

   sunk 
  135 
  feet 
  through 
  blue 
  clay. 
  Adding 
  to 
  this 
  108 
  feet 
  of 
  

   clay 
  above 
  mean 
  tide 
  gives 
  us 
  a 
  bed 
  of 
  clay 
  243 
  feet 
  thick. 
  The 
  

   terrace 
  which 
  the 
  clay 
  underlies 
  at 
  Roseton 
  extends 
  back 
  from 
  

   the 
  river 
  several 
  hundred 
  feet 
  into 
  a 
  reentrant 
  angle 
  of 
  the 
  hill. 
  

   The 
  clay 
  contains 
  little 
  sand 
  and 
  is 
  worked 
  in 
  benches. 
  Carts 
  

   are 
  used 
  to 
  haul 
  the 
  clay. 
  South 
  of 
  Roseton 
  station 
  is 
  a 
  bank 
  of 
  

   sand 
  of 
  alternating 
  yellow 
  and 
  grayish 
  black 
  layers, 
  which 
  has 
  been 
  

   used 
  for 
  tempering, 
  but 
  is 
  said 
  not 
  to 
  give 
  as 
  good 
  results 
  as 
  that 
  

   on 
  Jova's 
  premises.
