  sent 
  probably, 
  aa 
  remarked 
  i>\ 
  Walcott 
  (36:319) 
  a 
  bha-k 
  caught 
  

   on 
  the 
  line 
  of 
  the 
  fault. 
  A 
  Bimilair 
  case 
  has 
  been 
  made 
  known 
  

   \>\ 
  Vanuxem 
  from 
  tin- 
  East 
  Canada 
  creek, 
  when- 
  along 
  a 
  fault 
  

   a 
  Trenton 
  limestone 
  bed 
  lias 
  been 
  caught 
  between 
  the 
  Utica 
  

   >lul<- 
  and 
  the 
  Beekmantown 
  (Oalciferous) 
  limestone 
  io:210). 
  

   This 
  would 
  indicate 
  that 
  the 
  conglomerate 
  bed 
  was 
  the 
  first 
  

   it 
  stratum 
  within 
  or 
  below 
  the 
  Xormans 
  kill 
  shales. 
  Its 
  

   similarity 
  with 
  tin* 
  Moordener 
  kill 
  bed 
  permits 
  the 
  conclusion 
  

   that 
  it 
  is. 
  like 
  the 
  latter, 
  inclosed 
  in 
  the 
  shahs, 
  and 
  perhaps 
  

   continuous 
  with 
  it. 
  A 
  few 
  miles 
  south 
  of 
  Castleton 
  another 
  

   brecciated 
  limestone 
  bed, 
  intercalated 
  in 
  graptolite-bearing 
  Nor- 
  

   mans 
  kill 
  shahs, 
  was 
  discovered 
  by 
  Ford 
  (see 
  p. 
  503). 
  This 
  lies 
  

   direitly 
  in 
  the 
  strike 
  of 
  the 
  Moordener 
  kill 
  bed 
  and 
  is 
  probably 
  

   also 
  continuous 
  with 
  it. 
  

  

  The 
  conclusion 
  to 
  be 
  derived 
  from 
  the 
  observations 
  on 
  these 
  

   (oii-hunt 
  rate 
  beds, 
  which 
  is 
  of 
  the 
  greatest 
  import 
  for 
  the 
  pres- 
  

   ent 
  investigation, 
  is 
  that 
  there 
  is 
  intercalated 
  in 
  undoubted 
  Nor- 
  

   mans 
  kill 
  or 
  lower 
  Dicellograptus 
  shales 
  a 
  conglomerate 
  bed 
  

   which, 
  in 
  pebbles 
  as 
  well 
  as 
  matrix, 
  contains 
  as 
  its 
  youngest 
  

  

  -ils 
  those 
  of 
  lower 
  Trent 
  on 
  aspect. 
  The 
  occurrence 
  of 
  peb- 
  

   bles 
  of 
  two 
  different 
  kinds 
  of 
  limestone 
  (even 
  three 
  at 
  Rj 
  

   dorph 
  hill 
  i 
  means 
  that 
  the 
  formation 
  of 
  several 
  Trenton 
  

   Limestone 
  beds 
  must 
  have 
  preceded 
  the 
  deposition 
  of 
  these 
  

   shales, 
  mid 
  that 
  an 
  unconformity 
  exists 
  between 
  the 
  lirne- 
  

   Btone 
  and 
  the 
  shah-. 
  The 
  more 
  common 
  fossils 
  of 
  the 
  

   pebbles 
  have 
  however 
  been 
  found 
  also 
  in 
  the 
  matrix. 
  This 
  

   could 
  be 
  explained 
  either 
  by 
  the 
  assumption 
  that 
  some 
  fossils 
  

   me 
  separated 
  from 
  the 
  pebbles 
  and 
  embedded 
  in 
  the 
  

   matrix, 
  a 
  view 
  which 
  seems 
  to 
  be 
  supported 
  by 
  the 
  scarcity 
  of 
  

  

  -ils 
  in 
  the 
  matrix 
  and 
  opposed 
  by 
  the 
  occurrence 
  of
