  places, 
  especially 
  in 
  the 
  higher 
  ridges, 
  where 
  it 
  assumes 
  at 
  times 
  a 
  basaltic 
  

  

  character 
  '\ 
  Thus 
  far 
  it 
  would 
  seem 
  as 
  if 
  Lieutenant 
  Williams 
  were 
  

  

  following 
  Dr. 
  MacClelland 
  closely, 
  even 
  to 
  copying 
  the 
  unfortunate 
  word 
  

   " 
  basaltic/' 
  as 
  applied 
  to 
  an 
  unaltered 
  sedimentary 
  rock 
  ; 
  but 
  he 
  goes 
  on 
  

   and 
  says, 
  " 
  so 
  much 
  so, 
  that 
  towards 
  the 
  north 
  in 
  the 
  Prome 
  district 
  

   basaltic 
  trap 
  frequently 
  occurs 
  in 
  the 
  main 
  ridge." 
  It 
  would 
  thus 
  

   really 
  seem 
  that 
  the 
  term 
  " 
  basaltic 
  trap 
  " 
  is 
  due 
  to 
  the 
  too 
  facile 
  pen 
  

   of 
  Lieutenant 
  Williams, 
  and 
  that 
  somehow 
  or 
  other 
  the 
  term 
  which 
  no- 
  

   where 
  occurs 
  in 
  MacClelland's 
  reports 
  on 
  the 
  geology 
  of 
  the 
  district 
  has 
  

   become 
  appended 
  to 
  his 
  map. 
  How 
  far 
  Lieutenant 
  Williams 
  may 
  have 
  

   been 
  acquainted 
  with 
  what 
  may 
  be 
  almost 
  described 
  as 
  a 
  trappean 
  ash 
  

   bed, 
  which 
  occurs 
  at 
  three 
  spots 
  in 
  the 
  Prome 
  district, 
  and 
  portions 
  of 
  

   which 
  might 
  possibly 
  be 
  regarded 
  as 
  a 
  " 
  basaltic 
  trap" 
  I 
  am 
  unable 
  to 
  

   say 
  ; 
  but 
  he 
  clearly 
  regards 
  his 
  ' 
  ' 
  basaltic 
  trap 
  " 
  as 
  akin 
  and 
  to 
  some 
  

   extent 
  synonymous 
  with 
  the 
  very 
  different 
  basaltic 
  sandstone 
  of 
  

   MacClelland. 
  After 
  arriving 
  at 
  such 
  a 
  conclusion, 
  it 
  would 
  be 
  a 
  very 
  

   small 
  step 
  to 
  put 
  in 
  freely, 
  representative 
  patches 
  of 
  the 
  said 
  trap 
  here 
  

   and 
  there 
  throughout 
  the 
  Yomah 
  ; 
  and 
  this 
  is 
  all 
  the 
  explanation 
  I 
  can 
  

   suggest 
  for 
  their 
  appearance 
  on 
  Dr. 
  MacClelland's 
  map 
  in 
  spots 
  where 
  I 
  

   failed 
  to 
  re-discover 
  them, 
  and 
  for 
  the 
  complete 
  silence 
  which 
  Dr. 
  Mac- 
  

   Clelland 
  himself 
  maintains 
  regarding 
  them 
  in 
  his 
  written 
  description 
  of 
  

   the 
  geology 
  of 
  the 
  district. 
  

  

  A 
  broad 
  band 
  of 
  laterite 
  is 
  shown 
  on 
  Dr. 
  MacClelland's 
  map 
  fring- 
  

   ing 
  the 
  entire 
  Pegu 
  Yomah, 
  and 
  a 
  similar 
  one 
  skirting 
  the 
  granitic 
  region 
  

   east 
  of 
  the 
  Sittoung, 
  which 
  convey 
  a 
  very 
  exaggerated 
  idea 
  of 
  the 
  deve- 
  

   lopment 
  of 
  laterite 
  in 
  the 
  province. 
  The 
  Poungloung 
  range 
  is 
  shown 
  to 
  

   be 
  " 
  granitic/'' 
  and 
  the 
  prevailing 
  error 
  thereby 
  avoided 
  of 
  considering 
  it 
  

   to 
  be 
  mainly 
  composed 
  of 
  granite 
  or 
  " 
  igneous 
  rocks 
  " 
  as 
  depicted 
  by 
  Mr. 
  

   O'Riley. 
  It 
  may 
  indeed 
  be 
  doubted 
  if 
  any 
  granite, 
  save 
  in 
  the 
  form 
  of 
  

   veins, 
  occurs 
  in 
  the 
  Poungloung 
  range, 
  or 
  within 
  the 
  British 
  frontier 
  line 
  ; 
  

   though 
  the 
  schistose 
  rock, 
  of 
  which 
  the 
  Poungloung 
  consists, 
  displays 
  a
