  this 
  

   seolian

  or 
  "

  In 
  the

  were 
  found 
  

   shells 
  of 
  the 
  snail 
  (Pcecilozonites

  (undetermined). 
  

  

  Among 
  other 
  facts 
  indicating 
  subsidence 
  are 
  the 
  various 
  

   caverns 
  with 
  large 
  stalactites 
  and 
  stalagmites 
  now

   more

  of 
  the 
  sea

  filled 
  with 
  sea 
  

   water, 
  which 
  is 
  said 
  to 
  be 
  at 
  least 
  40 
  feet 
  deep

  some 
  of 
  

   them. 
  The 
  stalactites 
  descend 
  into 
  the

  in 
  some 
  

   cases.

  Cathedral 
  Rocks 
  on 
  Somerset 
  Island. 
  This 
  appears 
  to 
  be 
  the 
  

   ruins 
  of 
  an 
  ancient 
  cavern 
  and 
  water 
  passages 
  which 
  have 
  been 
  partly 
  broken 
  

   down 
  and 
  dissected 
  by 
  the 
  sea. 
  The 
  roof 
  has 
  partly 
  fallen 
  down. 
  The 
  columns 
  

   are 
  hardened 
  by 
  infiltration 
  and 
  roughly 
  pitted. 
  

  

  numbers 
  of 
  fishes 
  are 
  kept 
  confined, 
  is 
  such 
  a 
  cavern 
  from 
  

   which 
  the 
  roof 
  has 
  fallen 
  away. 
  The 
  sea 
  water 
  in 
  it 
  is 
  said 
  to 
  

   be 
  40 
  feet 
  deep. 
  

  

  Some 
  of 
  the 
  existing 
  peat 
  bogs 
  are 
  said 
  to 
  extend 
  to 
  the 
  

   depth 
  of 
  45 
  feet 
  beneath 
  sea 
  level, 
  and 
  to 
  contain 
  very 
  large 
  

   cedar 
  stumps. 
  Such 
  deposits 
  cannot 
  be 
  formed 
  here 
  except 
  

   above 
  sea 
  level, 
  for, 
  owing 
  to 
  the 
  porosity 
  of 
  the 
  rocks, 
  all 
  

   depressions 
  below 
  the 
  sea 
  level 
  become 
  filled 
  with 
  sea 
  water. 
  

   Thus 
  these 
  peat 
  bogs 
  afford 
  evidence 
  of 
  submergence, 
  for 
  the 
  

   peat 
  consists 
  of 
  the 
  remains 
  of 
  various 
  terrestrial 
  plants. 
  

  

  The 
  evidence 
  of 
  still 
  greater 
  subsidence 
  is 
  derived 
  from 
  the
