  Along 
  Bagley's 
  brook 
  east 
  of 
  Delancey 
  (formerly 
  Lansingville) 
  

   a 
  few 
  fossils 
  were 
  found 
  in 
  loose 
  pieces 
  of 
  shale 
  similar 
  to 
  those 
  

   in 
  the 
  Holmes 
  Hollow 
  brook:

  The 
  lower 
  slopes 
  of 
  the 
  hills 
  along 
  this 
  stream 
  are 
  also 
  covered 
  

   by 
  soil, 
  drift 
  and 
  gravel 
  so 
  that 
  there 
  is 
  no 
  opportunity 
  to 
  ex- 
  

   amine 
  the 
  bed 
  rocks. 
  Higher 
  in 
  the 
  hills 
  are 
  red 
  and 
  gray 
  sand- 
  

   stones 
  and 
  shales. 
  

  

  LXV 
  A. 
  On 
  the 
  eastern 
  side 
  of 
  the 
  Delaware 
  river 
  to 
  the 
  north- 
  

   east 
  of 
  Delhi 
  is 
  a 
  steep 
  hill 
  known 
  as 
  Federal 
  Hill. 
  Along 
  the 
  

   Federal 
  Hill 
  road 
  from 
  the 
  Delaware 
  valley 
  road 
  nearly 
  to 
  its 
  

   summit 
  are 
  frequent 
  ledges 
  of 
  red 
  sandstone 
  and 
  shales 
  alter- 
  

   nating 
  with 
  grayish 
  sandstones. 
  Near 
  the 
  summit 
  of 
  the 
  road 
  

   is 
  more 
  of 
  the 
  gray 
  sandstone 
  below 
  which 
  the 
  rocks 
  are 
  prevail- 
  

   ingly 
  red. 
  In 
  the 
  field 
  on 
  the 
  south 
  side 
  of 
  the 
  road, 
  about 
  65 
  

   feet 
  above 
  the 
  base 
  of 
  the 
  coarse 
  gray 
  sandstone 
  exposed 
  on 
  the 
  

   road 
  near 
  its 
  summit, 
  is 
  the 
  top 
  of 
  a 
  ledge 
  of 
  thick, 
  gray 
  sand- 
  

   stone. 
  However, 
  there 
  is 
  a 
  zone 
  of 
  red 
  between 
  the 
  top 
  and 
  

   bottom 
  of 
  this 
  mass 
  of 
  gray 
  sandstone. 
  On 
  the 
  Geologic 
  map 
  of 
  

   New 
  York 
  the 
  Oneonta 
  sandstone 
  is 
  represented 
  well 
  toward 
  

   the 
  summit 
  of 
  Federal 
  Hill, 
  which 
  is 
  apparently 
  correct, 
  but 
  its 
  

   top 
  is 
  mapped 
  as 
  capped 
  by 
  Chemung. 
  

  

  On 
  the 
  hill 
  south 
  of 
  the 
  Delaware 
  river 
  in 
  the 
  western 
  edge 
  of 
  

   Stamford 
  township, 
  opposite 
  Bloomville, 
  are 
  quite 
  thick 
  ledges 
  

   of 
  sandstone 
  near 
  the 
  boundary 
  line 
  between 
  the 
  Oneonta 
  and 
  

   Chemung 
  formations 
  as 
  represented 
  on 
  the 
  Geologic 
  map 
  of 
  New 
  

   York. 
  First 
  there 
  are 
  ledges 
  of 
  about 
  40 
  feet 
  of 
  greenish 
  gray, 
  

   coarse 
  grained 
  sandstone. 
  In 
  the 
  lower 
  part 
  of 
  these 
  sandstones 
  

   are 
  specimens 
  of 
  Rhodea 
  pinnata 
  Dd., 
  which 
  are 
  common 
  in 
  one 
  

   place. 
  Succeeding 
  the 
  gray 
  sandstones 
  are 
  those 
  that 
  are 
  red- 
  

   dish 
  and 
  thin 
  bedded, 
  at 
  least 
  35 
  feet 
  thick 
  with 
  a 
  layer 
  of 
  gray 
  

   sandstone 
  about 
  20 
  feet 
  above 
  their 
  base. 
  Then 
  the 
  rocks 
  are
