  silver 
  mines, 
  of 
  Juga, 
  in 
  the 
  

   district 
  of 
  Hoshangabad, 
  are 
  locally 
  well 
  known. 
  They 
  were 
  visited 
  in 
  

   1855 
  by 
  Mr. 
  H. 
  B. 
  Medlicott, 
  who 
  found 
  the 
  deposit 
  so 
  thoroughly 
  

   worked 
  out 
  that 
  he 
  had 
  difficulty 
  in 
  ascertaining 
  what 
  the 
  ore 
  was. 
  

   Some 
  excavations 
  were 
  made 
  there 
  by 
  Mr. 
  G. 
  J. 
  Nicholls. 
  The 
  speci- 
  

   mens 
  forwarded 
  by 
  him 
  were 
  found 
  on 
  analysis 
  by 
  Mr. 
  Mallet, 
  Curator 
  

   of 
  the 
  Geological 
  Museum, 
  to 
  be 
  useless 
  as 
  an 
  ore, 
  although 
  tc 
  indicating 
  

   the 
  possibility 
  of 
  galena 
  occurring 
  in 
  larger 
  quantity.'" 
  He 
  found 
  the 
  

   lead 
  extracted 
  from 
  the 
  galena 
  to 
  contain 
  21 
  ounces 
  of 
  silver

  Copper. 
  — 
  In 
  the 
  district 
  of 
  Nimawar 
  (Holkar), 
  at 
  a 
  village 
  called 
  

   Tamkhan 
  (lat. 
  22° 
  27', 
  long. 
  76° 
  54), 
  I 
  met 
  with 
  heaps 
  of 
  slags 
  from 
  

   copper 
  furnaces. 
  There 
  is 
  a 
  line 
  of 
  shallow 
  excavations 
  at 
  the 
  place, 
  

   and 
  the 
  ore 
  probably 
  occurred 
  as 
  a 
  vein 
  in 
  the 
  metamorphics. 
  But 
  it 
  has 
  

   been 
  worked 
  out; 
  and 
  I 
  could 
  not 
  find 
  any 
  trace 
  of 
  it. 
  I 
  may 
  remark 
  

   that 
  the 
  name 
  of 
  the 
  village 
  signifies 
  " 
  copper 
  mine." 
  

  

  I 
  heard 
  also 
  of 
  copper 
  mines 
  near 
  Xli 
  Raj 
  pur. 
  But 
  the 
  ground 
  was 
  

   not 
  examined. 
  

  

  Lime. 
  — 
  Numerous 
  pits 
  are 
  worked 
  in 
  the 
  Bijawar 
  limestone 
  for 
  

   lime. 
  The 
  lime 
  quarries 
  near 
  Barwai 
  and 
  at 
  Barjar 
  yield 
  a 
  very 
  supe- 
  

   rior 
  article, 
  which 
  is 
  taken 
  by 
  rail 
  to 
  as 
  far 
  north 
  as 
  Oujein. 
  In 
  the 
  

   Man 
  valley 
  and 
  further 
  west, 
  I 
  saw 
  a 
  few 
  lime-pits 
  in 
  the
