   Native 
  sulphur 
  is 
  of 
  common 
  occurrence 
  in 
  the 
  small 
  cavities 
  in 
  the 
  

   encrinital 
  limestone 
  at 
  the 
  Cold 
  Spring 
  quarries, 
  two 
  miles 
  east 
  of 
  

   Lockport, 
  Niagara 
  county.

  BITUMEN.

  Mr. 
  Hall 
  inform^ 
  us 
  that 
  fluid 
  bitumen 
  is 
  of 
  common 
  occurrence 
  in 
  

   the 
  Genesee 
  slate, 
  and 
  with 
  it 
  a 
  bright 
  blue 
  fluid 
  and 
  a 
  substance 
  like 
  

   spermaceti, 
  but 
  softer. 
  These 
  are 
  volatile, 
  and 
  it 
  has 
  been 
  impossible 
  

   to 
  preserve 
  any 
  of 
  them. 
  The 
  fluid 
  bitumen 
  and 
  the 
  blue 
  fluid 
  have 
  

   likewise 
  been 
  noticed 
  in 
  septaria, 
  in 
  the 
  Marcellus 
  slate.

  Mr. 
  Hall 
  has 
  a 
  cut 
  # 
  of 
  the 
  Oil 
  Spring 
  in 
  Freedom, 
  Cattaragus 
  county. 
  

   He 
  remarks 
  that 
  the 
  origin 
  of 
  the 
  spring 
  is 
  doubtless 
  from 
  the 
  bitumin- 
  

   ous 
  matter 
  which 
  is 
  carried 
  down 
  by 
  the 
  water 
  as 
  it 
  percolates 
  through 
  

   the 
  interstices 
  of 
  the 
  sandstone.

  Several 
  localities 
  of 
  this 
  useful 
  mineral 
  occur 
  in 
  Northern 
  New- 
  York 
  

   which 
  it 
  is 
  probable 
  will 
  yield 
  an 
  abundant 
  supply. 
  The 
  Ticonderoga 
  

   deposits 
  are 
  already 
  turned 
  to 
  considerable 
  profit. 
  In 
  the 
  village 
  of 
  

   Keeseville, 
  at 
  a 
  short 
  distance 
  from 
  these 
  deposits, 
  there 
  are 
  three 
  

   manufactories 
  of 
  pencil 
  points, 
  which 
  send 
  out 
  several 
  millions 
  annu- 
  

   ally. 
  Large 
  quantities 
  of 
  the 
  mineral 
  in 
  powder 
  are 
  also 
  consumed 
  for 
  

   stove 
  blacking, 
  for 
  which 
  purpose 
  it 
  is 
  considered 
  by 
  many 
  equal 
  to 
  the 
  

   celebrated 
  " 
  British 
  Lustre." 
  

  

  A 
  new 
  method 
  has 
  been 
  recently 
  proposed 
  by 
  Profs. 
  K. 
  E. 
  and 
  W. 
  

   B. 
  Rogers, 
  for 
  determining 
  the 
  carbon 
  in 
  native 
  and 
  artificial 
  Graphites.
