  of 
  about 
  12 
  to 
  15 
  feet 
  in 
  thickness, 
  passing 
  down 
  into 
  ferruginous 
  sand- 
  

   stone. 
  It 
  is 
  traceable 
  for 
  some 
  distance 
  along 
  the 
  scarp 
  of 
  the 
  hills 
  

   to 
  the 
  westward, 
  but 
  appears 
  to 
  thin 
  off 
  to 
  the 
  east 
  : 
  at 
  Chorvira, 
  in 
  the 
  

   latter 
  direction, 
  it 
  is 
  only 
  a 
  very 
  few 
  feet 
  in 
  thickness; 
  and 
  it 
  is 
  suc- 
  

   ceeded, 
  above 
  and 
  below, 
  by 
  the 
  light-coloured 
  soft 
  sandstone. 
  

  

  In 
  former 
  days 
  this 
  ferruginous 
  band 
  was 
  worked, 
  and 
  the 
  ore 
  

   smelted 
  for 
  iron 
  in 
  many 
  places, 
  notably 
  at 
  the 
  village 
  of 
  Kantrori, 
  

   8 
  miles 
  west 
  of 
  Sara. 
  Scarcity 
  of 
  fuel 
  and 
  the 
  cheapness 
  of 
  the 
  

   imported 
  metal 
  have 
  caused 
  this 
  industry 
  to 
  die 
  out. 
  

  

  Among 
  the 
  sandstones 
  below 
  the 
  ferruginous 
  zone, 
  there 
  occurs 
  a 
  

  

  band 
  of 
  thinly-laminated 
  fine 
  shaly 
  sandstone, 
  or 
  arenaceous 
  shale, 
  

  

  associated 
  with 
  dark 
  argillaceous 
  and 
  carbonaceous 
  

   Plant 
  shales. 
  

  

  shale, 
  the 
  latter 
  containing 
  numerous 
  impressions, 
  

  

  mostly 
  fragmentary, 
  of 
  fossil 
  plants, 
  leaves, 
  seeds, 
  &c. 
  The 
  fossils 
  were 
  

  

  obtained 
  from 
  two 
  localities— 
  one 
  near 
  the 
  village 
  of 
  Songadh 
  2 
  J 
  miles 
  

  

  N.N.E. 
  of 
  Than, 
  and 
  the 
  other 
  three-quarters 
  of 
  a 
  mile 
  north-west 
  of 
  

  

  Than. 
  There 
  is 
  a 
  very 
  limited 
  exposure 
  of 
  the 
  beds 
  at 
  either 
  place. 
  The 
  

  

  specimens 
  from 
  Songadh 
  comprise, 
  on 
  the 
  authority 
  of 
  Dr. 
  Feistmantel 
  

  

  the 
  following 
  : 
  — 
  

  

  Filices. 
  

  

  Pecopteris, 
  sp. 
  

  

  Tceniojoteris, 
  sp. 
  

  

  Cycadeace^j. 
  

  

  Podozamites 
  lanceolatus. 
  

  

  Conifers. 
  

   Echinostrobus 
  {Thuites) 
  expansus. 
  

   Of 
  these 
  plants, 
  the 
  last 
  named 
  is 
  common 
  to 
  both 
  the 
  Jabalpur 
  

   and 
  the 
  Umia 
  (Cutch) 
  groups 
  ; 
  while 
  the 
  Podozamites 
  was 
  known 
  in 
  

   the 
  former 
  group 
  only. 
  

  

  The 
  second 
  locality 
  (north-west 
  of 
  Than) 
  proved 
  the 
  richer, 
  and 
  

   the 
  specimens 
  obtained 
  therefrom 
  have 
  been 
  named 
  and 
  discussed 
  by 
  

   Dr. 
  Feistmantel 
  in 
  a 
  short 
  paper 
  published 
  in 
  1880.
