  Marble. 
  — 
  In 
  1878 
  it 
  was 
  reported 
  to 
  me 
  that 
  statuary 
  marble 
  'in 
  

   any 
  quantity 
  ' 
  had 
  been 
  discovered 
  in 
  the 
  Gondal 
  State, 
  and 
  that 
  quarries 
  

   had 
  been 
  opened 
  in 
  it. 
  The 
  so-called 
  c 
  marble 
  quarries 
  ' 
  proved 
  to 
  be 
  

   some 
  very 
  limited 
  surface 
  diggings 
  along 
  an 
  irregular 
  vein 
  in 
  the 
  trap 
  

   rocks, 
  near 
  the 
  villages 
  of 
  Khirasra 
  and 
  Sejriala 
  in 
  the 
  Bhayawadar 
  

   pargana, 
  about 
  15 
  miles 
  north-west 
  of 
  Dhoraji. 
  The 
  vein 
  is 
  not 
  more 
  

   than 
  about 
  30 
  inches 
  in 
  width, 
  often 
  less; 
  and 
  the 
  marble 
  is 
  associ- 
  

   ated 
  with 
  quartz 
  and 
  other 
  spars, 
  such 
  as 
  coarsely 
  crystallized 
  calcite 
  

   (calc-spar) 
  of 
  which 
  the 
  vein 
  is 
  largely 
  made 
  up 
  in 
  places. 
  The 
  work- 
  

   able 
  stone 
  is 
  a 
  white-mottled 
  hard 
  marble, 
  capable 
  of 
  a 
  high 
  polish, 
  and 
  

   consists 
  of 
  a 
  mingled 
  combination 
  of 
  aragonite 
  and 
  calcite. 
  I 
  do 
  not 
  

   consider 
  it 
  could 
  be 
  worked 
  profitably 
  for 
  exportation, 
  but 
  it 
  might 
  be 
  

   locally 
  employed 
  for 
  ornamental 
  purposes 
  in 
  a 
  small 
  way. 
  

  

  The 
  stone 
  is 
  interesting 
  from 
  a 
  mineralogical 
  point 
  of 
  view 
  : 
  it 
  is 
  

   decidedly 
  harder 
  than 
  ordinary 
  white 
  marble, 
  and 
  somewhat 
  heavier 
  ; 
  

   neither 
  has 
  it 
  any 
  distinct 
  rhombic 
  cleavage. 
  Mr. 
  Mallet 
  has 
  deter- 
  

   mined 
  it 
  to 
  be 
  et 
  remarkably 
  pure 
  carbonate 
  of 
  lime, 
  without 
  any 
  appre- 
  

   ciable 
  quantity 
  of 
  either 
  iron 
  or 
  magnesia/'' 
  Its 
  specific 
  gravity 
  is 
  2*87 
  

   (which 
  is 
  higher 
  than 
  any 
  calcite, 
  and 
  a 
  little 
  under 
  ordinary 
  aragonite). 
  

   Its 
  hardness 
  ( 
  3'5 
  — 
  4) 
  more 
  nearly 
  agrees 
  with 
  aragonite. 
  When 
  

   strongly 
  heated, 
  before 
  the 
  blow-pipe, 
  it 
  does 
  not 
  fall 
  to 
  pieces 
  like 
  

   aragonite, 
  but 
  becomes 
  opaque 
  and 
  more 
  readily 
  friable 
  than 
  ordinary 
  

   white 
  marble 
  after 
  being 
  similarly 
  heated.
