  Forty-seventh 
  Report 
  on 
  the 
  State 
  Museum, 
  

  

  containing 
  Niagara 
  corals. 
  On 
  this 
  there 
  lie 
  seven 
  feet 
  of 
  dark- 
  

   gray 
  limestones, 
  impure 
  near 
  the 
  base, 
  and 
  for 
  two 
  feet 
  toward 
  the 
  

   top. 
  Two 
  feet 
  above 
  their 
  bottom 
  is 
  a 
  fossiliferous 
  layer 
  con- 
  

   taining 
  Atryjpa 
  reticularis, 
  a 
  very 
  unusual 
  occurrence 
  in 
  this 
  part 
  

   of 
  the 
  formation. 
  This 
  limestone 
  is 
  overlaid 
  by 
  a 
  ten-foot 
  bed 
  

   of 
  cement 
  rock, 
  of 
  which 
  the 
  upper 
  four 
  feet 
  are 
  of 
  poor 
  quality. 
  

   Next 
  above 
  is 
  a 
  heavy 
  mass 
  of 
  fine-grained, 
  dark-colored, 
  brecciated 
  

   limestone, 
  filled 
  with 
  a 
  great 
  variety 
  of 
  corals 
  representing 
  

   the 
  Stromatopora 
  layer 
  of 
  the 
  Tentaculite 
  series. 
  It 
  has 
  here 
  

   the 
  very 
  remarkable 
  thickness 
  of 
  ten 
  feet 
  with 
  only 
  a 
  few 
  thin 
  

   beds 
  of 
  typical 
  Tentaculite 
  members 
  above. 
  These 
  are 
  overlaid 
  

   by 
  the 
  heavily-bedded 
  Pentamerus 
  limestone, 
  which, 
  in 
  the- 
  

   Kingston 
  region, 
  are 
  quite 
  cherty. 
  A 
  slight 
  change 
  in 
  the 
  strike 
  

   in 
  this 
  vicinity 
  is 
  a 
  notable 
  feature, 
  the 
  relations 
  of 
  which 
  are 
  

   shown 
  in 
  plate 
  4. 
  It 
  appears 
  to 
  be 
  connected 
  with 
  the 
  anticlinal 
  

   shown 
  in 
  section 
  II 
  of 
  this 
  plate. 
  This 
  anticlinal 
  brings 
  up 
  the 
  

   Tentaculite 
  and 
  Cement 
  horizons 
  to 
  the 
  top 
  of 
  the 
  ridge 
  on 
  the 
  

   line 
  of 
  section 
  II, 
  and 
  they 
  are 
  exposed 
  just 
  north 
  of 
  the 
  road: 
  

   The 
  synclinal 
  to 
  the 
  east 
  widens 
  to 
  the 
  southward, 
  and 
  holds 
  an 
  

   area 
  of 
  lower 
  Shaly 
  limestone 
  which 
  passes 
  over 
  the 
  anticlinal 
  

   and 
  occupies 
  a 
  belt 
  of 
  considerable 
  width 
  in 
  a 
  series 
  of 
  rough 
  

   ridges 
  lying 
  west 
  of 
  the 
  crest 
  of 
  the 
  main 
  ridge. 
  

  

  Passing 
  along 
  the 
  northern 
  road 
  over 
  the 
  ridge, 
  there 
  are 
  

   extensive 
  exposures 
  of 
  the 
  upper 
  and 
  lower 
  Shaly 
  limestones 
  with 
  

   the 
  intervening 
  Becraft 
  limestone, 
  and 
  the 
  overlying 
  Oriskany 
  

   beds. 
  The 
  Shaly 
  limestones 
  present 
  their 
  usual 
  characteristics 
  of 
  

   dark-gray, 
  impure, 
  moderately 
  thick-bedded 
  limestones, 
  traversed 
  

   by 
  pronounced 
  slaty 
  cleavage. 
  The 
  Becraft 
  limestone 
  is 
  in 
  heavy 
  

   beds, 
  having 
  an 
  aggregate 
  thickness 
  of 
  about 
  thirty 
  feet. 
  The 
  

   Oriskany 
  consists 
  of 
  gray, 
  very 
  silicious, 
  highly 
  fossiliferous 
  

   limestone 
  above, 
  with 
  coarse 
  sandstones 
  below. 
  The 
  dips 
  in 
  this 
  

   region 
  gradually 
  increase 
  in 
  steepness 
  from 
  the 
  anticlinal, 
  west- 
  

   ward 
  to 
  eighty 
  degrees 
  in 
  the 
  Oriskany 
  outcrops. 
  The 
  Oriskany 
  

   beds 
  give 
  rise 
  to 
  a 
  sharply 
  defined 
  subordinate 
  ridge, 
  extending 
  

   along 
  the 
  slope 
  of 
  the 
  upper 
  Shaly 
  ridge. 
  To 
  the 
  westward 
  there 
  

   is 
  a 
  wide 
  belt 
  of 
  Esopus 
  shales 
  which 
  outcrop 
  in 
  a 
  series 
  of 
  abrupt 
  

   ridges 
  of 
  moderate 
  height, 
  but 
  considerable 
  steepness. 
  There 
  are 
  

   several 
  flexures 
  on 
  this 
  belt, 
  of 
  which 
  the 
  character 
  is 
  shown 
  in 
  

   section 
  on 
  plate 
  4.
