  Concretions 
  are 
  abundant 
  in 
  the 
  clay 
  on 
  Center 
  island 
  and 
  Weet 
  

   neck. 
  Those 
  found 
  at 
  the 
  latter 
  locality 
  are 
  disc-shaped, 
  while 
  

   those 
  found 
  on 
  Center 
  island 
  are 
  more 
  or 
  less 
  botrvoidal. 
  

  

  Silicified 
  yellow 
  gravel 
  fossils 
  have 
  been 
  found 
  by 
  the 
  writer 
  

   in 
  the 
  sands 
  on 
  West 
  neck/ 
  and 
  more 
  were 
  subsequently 
  found 
  

   in 
  other 
  localities 
  by 
  Dr 
  HoUick.^ 
  

  

  On 
  Little 
  neck, 
  in 
  ISTorthport 
  bay, 
  is 
  an 
  extensive 
  deposit 
  of 
  

   stoneware 
  clay 
  and 
  fire 
  sand, 
  which 
  has 
  been 
  worked 
  for 
  a 
  num- 
  

   ber 
  of 
  years. 
  The 
  clay 
  is 
  stratified, 
  the 
  layers 
  being 
  separated 
  

   by 
  laminae 
  of 
  sand. 
  In 
  color 
  the 
  material 
  varies 
  from 
  black 
  to 
  

   brown 
  and 
  yellow, 
  and 
  it 
  becomes 
  sandy 
  in 
  its 
  upper 
  portion. 
  

   There 
  is 
  a 
  dip 
  of 
  15° 
  se 
  due 
  to 
  a 
  slipping 
  of 
  the 
  clay 
  bank. 
  

   Overlying 
  the 
  clay 
  is 
  cross-bedded 
  fine 
  sand 
  and 
  gravel, 
  the 
  latter 
  

   containing 
  much 
  coarse 
  material 
  near 
  the 
  surface. 
  Very 
  little 
  

   till 
  covers 
  the 
  whole. 
  Much 
  fine, 
  white 
  fire 
  sand 
  occurs 
  in 
  por- 
  

   tions 
  of 
  the 
  bank. 
  A 
  careful 
  examination 
  of 
  the 
  section 
  showed 
  

   a 
  brownish 
  black 
  seam 
  of 
  the 
  clay, 
  2 
  feet 
  thick, 
  containing 
  

   numerous 
  fragments 
  of 
  plant 
  remains, 
  of 
  which 
  a 
  number 
  were 
  

   sufficiently 
  well 
  preserved 
  to 
  determine 
  the 
  Cretaceous 
  age 
  of 
  the 
  

   clay 
  beyond 
  doubt. 
  The 
  species 
  were 
  identified 
  for 
  me 
  by 
  Dr 
  

   ITollick 
  as 
  follows:
