  to 
  Dana, 
  occurs 
  in 
  the 
  petroleum 
  of 
  Pennsylvania, 
  but 
  the 
  American 
  

   oils 
  are 
  usually 
  deficient 
  in 
  paraffine. 
  G-esner, 
  however, 
  says 
  that 
  paraffme 
  

   exists 
  in 
  the 
  Ouachita 
  coal 
  of 
  Arkansas 
  to 
  the 
  extent 
  of 
  143 
  pounds 
  

   per 
  ton. 
  The 
  paler 
  oils 
  of 
  Ramri 
  and 
  other 
  parts 
  of 
  Arakan, 
  having 
  

   a 
  less 
  specific 
  gravity 
  than 
  the 
  commercial 
  oil 
  of 
  Rangoon, 
  are 
  possibly 
  

   as 
  deficient 
  in 
  pararfine 
  as 
  the 
  American 
  oil, 
  which 
  they 
  so 
  much 
  resem- 
  

   ble, 
  but 
  no 
  adequate 
  analysis 
  has 
  ever 
  been 
  made 
  to 
  settle 
  this 
  impor- 
  

   tant 
  point, 
  and 
  the 
  Arakan 
  and 
  Burmese 
  oils 
  are 
  certainly 
  derived 
  from 
  

   beds 
  of 
  the 
  same 
  geological 
  age, 
  hence 
  their 
  poverty 
  in 
  pararfine 
  should 
  

   not 
  perhaps 
  be 
  assumed 
  from 
  their 
  outward 
  character. 
  

  

  Road-materials. 
  — 
  Good 
  road-materials 
  are 
  scarce 
  in 
  Pegu, 
  in 
  fact 
  

   there 
  are 
  none 
  suitable 
  for 
  roads 
  on 
  which 
  heavy 
  traffic 
  is 
  carried 
  on. 
  

   In 
  Rangoon 
  of 
  course, 
  excellent 
  road-material 
  is 
  procurable, 
  in 
  the 
  shape 
  

   of 
  ship's 
  ballast, 
  but 
  in 
  the 
  interior 
  of 
  the 
  country 
  soft 
  sandstones 
  are 
  

   the 
  prevalent 
  material, 
  with 
  a 
  little 
  laterite 
  of 
  usually 
  rather 
  inferior 
  

   quality. 
  This 
  paucity 
  of 
  good 
  materials 
  for 
  road-making 
  is 
  less 
  felt 
  in 
  

   a 
  country 
  where 
  wheeled 
  vehicles 
  are 
  usually 
  reserved 
  for 
  agricultural 
  

   purposes, 
  and 
  the 
  transport 
  of 
  grain 
  across 
  country 
  in 
  the 
  dry 
  weather, 
  when 
  

   the 
  crops 
  are 
  off 
  the 
  ground, 
  and 
  the 
  carriage 
  of 
  other 
  goods 
  and 
  mer- 
  

   chandise 
  is 
  mainly 
  effected 
  on 
  pack 
  bullocks 
  and 
  ponies. 
  The 
  serpen- 
  

   tine 
  of 
  the 
  Arakan 
  range 
  would 
  certainly 
  form 
  a 
  good 
  road-material, 
  but 
  

   it 
  is 
  hardly 
  worth 
  while 
  dwelling 
  on 
  this, 
  as 
  road 
  metal 
  is 
  too 
  heavy 
  an 
  

   article 
  to 
  bear 
  distant 
  transport, 
  and 
  the 
  roads 
  of 
  Pegu 
  must 
  of 
  necessity 
  

   be 
  constructed 
  of 
  the 
  materials 
  nearest 
  at 
  hand, 
  however 
  inferior 
  for 
  

   the 
  purpose 
  they 
  may 
  be. 
  

  

  Salt.— 
  The 
  manufacture 
  of 
  salt, 
  from 
  the 
  feeble 
  brine 
  springs 
  of 
  the 
  

   province, 
  which 
  once 
  formed 
  a 
  considerable 
  local 
  industry, 
  has 
  now 
  

   almost 
  entirely 
  ceased, 
  owing 
  to 
  the 
  greater 
  cheapness 
  with 
  which 
  

   the 
  sea 
  salt 
  manufactured 
  in 
  lower 
  Pegu 
  and 
  even 
  imported 
  English 
  

   salt, 
  is 
  now 
  procurable. 
  An 
  enumeration 
  of 
  the 
  various 
  localities 
  where 
  

   brine 
  springs

  been 
  given
