  The 
  next 
  spot 
  where 
  this 
  limestone 
  occurs 
  largely 
  is 
  a 
  few 
  miles^ 
  

   South-west 
  of 
  Ki-ben-ziaht, 
  a 
  village 
  on 
  the 
  Tan-loay 
  stream, 
  not 
  quite 
  

   half 
  way 
  from 
  Maii, 
  to 
  the 
  mouth 
  of 
  the 
  Sandoway 
  river. 
  It 
  here 
  

   occurs 
  in 
  considerable 
  quantity 
  in 
  undulating 
  ground, 
  but 
  its 
  relation 
  to- 
  

   any 
  other 
  beds 
  is 
  not 
  seen. 
  Thus 
  far 
  I 
  think 
  there 
  is 
  little 
  doubt 
  that 
  

   these 
  outcrops 
  are 
  all 
  portions 
  of 
  one 
  and 
  the 
  same 
  bed, 
  re-appearing 
  at 
  

   intervals 
  and 
  probably 
  discoverable 
  at 
  more 
  spots 
  than 
  my 
  hasty 
  examina- 
  

   tion 
  enabled 
  me 
  to 
  detect, 
  but 
  whether 
  or 
  no 
  the 
  same 
  bed 
  is 
  identical 
  

   with 
  some 
  outcrops 
  of 
  rock 
  of 
  very 
  similar 
  mineral 
  aspect 
  farther 
  South, 
  

   is 
  not 
  equally 
  clear. 
  For 
  instance, 
  close 
  to 
  Tonghoop, 
  a 
  small 
  outcrop 
  of 
  

   limestone 
  is 
  seen 
  which 
  may 
  belong 
  to 
  this 
  bed, 
  and 
  North 
  of 
  it, 
  about 
  

   three 
  miles, 
  some 
  limestone, 
  which 
  probably 
  is 
  the 
  same; 
  it 
  is 
  seen 
  in 
  the 
  

   bed 
  of 
  the 
  stream 
  up 
  which 
  the 
  road 
  winds 
  ; 
  and 
  again 
  farther 
  South 
  another 
  

   outcrop 
  occurs 
  five 
  miles 
  North-west 
  of 
  Sandoway. 
  Between 
  Sandoway 
  

   and 
  Kyeantalee, 
  limestone 
  occurs 
  at 
  several 
  spots, 
  but 
  usually 
  more 
  or 
  less 
  

   sub-crystalline 
  in 
  character, 
  and 
  not 
  so 
  argillaceous 
  as 
  the 
  Kamah 
  rock. 
  

   At 
  Sanday, 
  four 
  miles 
  above 
  Kyeantalee, 
  on 
  the 
  opposite 
  side 
  of 
  the 
  river, 
  

   occurs 
  an 
  argillaceous 
  limestone 
  which 
  may 
  belong 
  to 
  this 
  group, 
  but 
  

   which 
  I 
  have 
  already 
  noticed, 
  from 
  its 
  close 
  juxta-position 
  to 
  a 
  small 
  

   outcrop 
  of 
  Nummulitic 
  limestone, 
  as 
  the 
  probable 
  representative 
  of 
  the 
  

   argillaceous 
  c 
  Andagu 
  kyouk' 
  of 
  the 
  Eastern 
  side 
  of 
  the 
  range. 
  Besides 
  

   the 
  above 
  limestone 
  there 
  is 
  another 
  peculiar 
  kind 
  of 
  rock 
  which 
  may 
  be 
  

   used 
  to 
  trace 
  the 
  extent 
  of 
  the 
  Cretaceous 
  group, 
  to 
  which 
  it 
  would 
  seem 
  

   to 
  belono* 
  to 
  the 
  South. 
  This 
  peculiar 
  rock, 
  which 
  is 
  first 
  met 
  with 
  

   about 
  two 
  and 
  a 
  half 
  miles 
  North-east 
  of 
  Kyeantalee, 
  is 
  a 
  greyish, 
  rather 
  

   earthy 
  sandstone, 
  which 
  in 
  places 
  exhibits 
  a 
  pisolitic 
  structure, 
  from 
  the 
  

   dissemination 
  through 
  it 
  of 
  small 
  globular 
  concretions 
  of 
  carbonate 
  of 
  

   lime 
  and 
  iron 
  (with 
  a 
  trace 
  of 
  magnesia 
  according 
  to 
  an 
  analysis 
  by 
  

   Mr. 
  Mallet) 
  which 
  rarely 
  exceed 
  the 
  size 
  of 
  a 
  small 
  pea. 
  These 
  concre- 
  

   tions, 
  which 
  must 
  be 
  considered 
  as 
  of 
  cotemporary 
  age 
  with 
  the 
  rock, 
  and 
  

   the 
  result 
  of 
  segregative 
  or 
  crystalline 
  action 
  previous 
  to 
  its 
  consolidation, 
  

   arc 
  sparingly 
  distributed 
  through 
  it, 
  and 
  very 
  irregularly 
  likewise,
