  Sandy 
  shales, 
  quite 
  hard, 
  with 
  some 
  calcareous 
  layers 
  of 
  

   the 
  Fame 
  character 
  as 
  the 
  bed 
  immediately 
  over 
  the 
  limestone, 
  

   and 
  containing 
  fossils 
  of 
  the 
  same 
  species. 
  Corals 
  predominate. 
  

   The 
  line 
  of 
  separation 
  between 
  this 
  and 
  the 
  bed 
  below 
  is 
  well 
  

   denned.

  34' 
  Soft 
  dark 
  rock, 
  with 
  layers 
  of 
  light 
  blue 
  to 
  olive 
  barren 
  

   shale, 
  which 
  predominate 
  in 
  the 
  middle 
  of 
  the 
  bed, 
  and 
  in 
  the 
  

   lower 
  part 
  are 
  about 
  equal 
  in 
  proportion. 
  Joints 
  or 
  cracks 
  

   frequently 
  filled 
  with 
  a 
  thin 
  vein 
  of 
  calcite 
  are 
  very 
  numerous 
  

   in 
  these 
  beds. 
  Their 
  principal 
  direction 
  is 
  nearly 
  east 
  and 
  

   west, 
  but 
  they 
  meet 
  each 
  other 
  at 
  all 
  angles 
  and 
  make 
  danger- 
  

   ous 
  ground 
  for 
  the 
  miners. 
  Taken 
  as 
  a 
  whole, 
  fossils 
  are 
  

   rare, 
  though 
  a 
  few 
  thin 
  layers 
  are 
  made 
  up 
  of 
  Liorhynchus 
  

   multicosta, 
  Amboccelia 
  umbonata 
  ; 
  Spirifer 
  mucronatus, 
  

   Chonetes 
  scitula, 
  Orbicidoidea 
  media, 
  Productella 
  qpinu- 
  

   lieostvu, 
  Stropheodonta

  triqueter, 
  Panenka 
  osquilatera, 
  

   JParacyclas 
  lineatus, 
  and 
  Phthonia 
  nodocostata 
  are 
  also 
  

   present, 
  and 
  plant

  are 
  quite
