﻿MAI-I

  remains, 
  these 
  rocks 
  of 
  doubtful 
  age 
  must 
  remain 
  classed 
  as 
  I 
  have 
  

   already 
  done, 
  in 
  a 
  provisional 
  group 
  (Negrais) 
  intermediate 
  in 
  position 
  

   between 
  the 
  Cretaceous 
  beds 
  and 
  the 
  Tertiaries. 
  

  

  One 
  bed 
  which 
  I 
  regard 
  as 
  belonging 
  to 
  the 
  group 
  which 
  contains 
  

   A. 
  injlatus, 
  is 
  a 
  limestone 
  of 
  a 
  light 
  cream 
  color, 
  in 
  places 
  exhibiting 
  a 
  

   somewhat 
  speckled 
  or 
  flea-bitten 
  aspect, 
  from 
  the 
  dissemination 
  through 
  

   it 
  of 
  sublenticular 
  crystalline 
  particles, 
  some 
  of 
  which 
  may 
  possibly 
  be 
  of 
  

   foraminiferous 
  origin. 
  The 
  rock 
  is 
  argillaceous, 
  very 
  homogeneous 
  in 
  

   grain, 
  occasionally 
  seamed 
  with 
  calcite, 
  and 
  breaks 
  with 
  a 
  subconchoidal 
  

   fracture. 
  I 
  think 
  it 
  probable 
  that 
  there 
  are 
  more 
  beds 
  than 
  one 
  of 
  this 
  

   character, 
  as 
  in 
  one 
  place 
  a 
  thin 
  bed 
  of 
  it 
  was 
  seen 
  intercalated 
  with 
  

   the 
  shales 
  of 
  this 
  group, 
  whilst 
  at 
  other 
  spots 
  where 
  the 
  rock 
  was 
  

   much 
  more 
  largely 
  developed, 
  its 
  relation 
  to 
  any 
  other 
  beds 
  was 
  not 
  

   so 
  perceptible. 
  The 
  first 
  spot 
  where 
  this 
  rock 
  occurs, 
  commencing 
  in 
  the 
  

   North 
  of 
  the 
  Sandoway 
  district, 
  is 
  four 
  miles 
  South-south-west 
  of 
  Mai-i, 
  

   where 
  it 
  constitutes 
  a 
  small 
  hill 
  not 
  two 
  hundred 
  yards 
  in 
  circumference, 
  

   on 
  the 
  edge 
  of 
  some 
  paddy-land, 
  bordering 
  a 
  tidal 
  creek. 
  It 
  is 
  here 
  

   quarried 
  and 
  burnt 
  for 
  local 
  use, 
  but 
  a 
  brisk 
  demand 
  for 
  lime 
  would 
  

   soon 
  make 
  serious 
  inroads 
  on 
  the 
  amount 
  of 
  rock 
  here 
  exposed. 
  About 
  

   twelve 
  miles 
  South-south-east 
  of 
  this, 
  a 
  much 
  larger 
  development 
  of 
  

   what 
  I 
  take 
  to 
  be 
  the 
  same 
  bed 
  occurs 
  at 
  some 
  distance 
  up 
  a 
  small 
  stream 
  

   not 
  laid 
  down 
  in 
  the 
  map, 
  but 
  which 
  may 
  be 
  termed 
  the 
  Kamah 
  stream, 
  

   from 
  the 
  name 
  of 
  the 
  village 
  situated 
  on 
  its 
  banks. 
  The 
  spot 
  being 
  some- 
  

   what 
  out 
  of 
  the 
  way 
  and 
  unapproachable 
  for 
  elephants, 
  was 
  not 
  visited 
  

   by 
  me 
  ; 
  but 
  from 
  samples 
  of 
  the 
  rock 
  it 
  is, 
  I 
  consider, 
  identical 
  with 
  

   that 
  at 
  Mai-i. 
  It 
  is 
  too 
  inaccessible 
  to 
  be 
  of 
  any 
  present 
  practical 
  value, 
  

   especially 
  as 
  the 
  same 
  rock 
  occurs 
  more 
  favorably 
  situated 
  elsewhere."* 
  

  

  * 
  The 
  Kamah 
  hill, 
  formed 
  of 
  this 
  limestone, 
  is 
  celebrated 
  for 
  a 
  large 
  cave 
  tenanted 
  by- 
  

   great 
  numbers 
  of 
  a 
  recently 
  described 
  frugivorous 
  bat, 
  Macroglossus 
  speloeus 
  Dobson, 
  the 
  

   same 
  species 
  as 
  that 
  inhabiting 
  the 
  farm 
  caves 
  near 
  Moulmein, 
  and 
  I 
  believe 
  some 
  others 
  

   in 
  Burmah.
