  The 
  small 
  quantity 
  of 
  titanium 
  shown 
  in 
  analyses 
  Nos. 
  2 
  and 
  3 
  

   is 
  interesting, 
  though 
  metallurgically 
  negligible. 
  It 
  seems 
  to 
  be 
  

   carried 
  by 
  the 
  mineral 
  titanite 
  which 
  is 
  intergrown 
  with 
  the 
  magne- 
  

   tite. 
  The 
  phosphorus 
  averages 
  about 
  .008 
  in 
  the 
  concentrates 
  

   now 
  made. 
  

  

  In 
  the 
  report 
  by 
  Putnam 
  are 
  given 
  the 
  following 
  incomplete 
  

   analyses 
  of 
  furnace 
  ore 
  and 
  concentrates. 
  The 
  latter 
  were 
  pre- 
  

   pared 
  by 
  jigging, 
  a 
  system 
  of 
  concentration 
  formerly 
  employed 
  at 
  

   the 
  mines. 
  The 
  sample 
  of 
  furnace 
  ore 
  (1) 
  was 
  an 
  average 
  of 
  22 
  

   carloads; 
  that 
  of 
  concentrates 
  (2) 
  an 
  average 
  of 
  120 
  tons.

  The 
  character 
  of 
  the 
  gangue 
  material, 
  which 
  in 
  a 
  way 
  may 
  be 
  

   regarded 
  as 
  closely 
  allied 
  to 
  the 
  country 
  gneiss, 
  is 
  shown 
  by 
  the 
  

   subjoined 
  analysis 
  of 
  tailings 
  from 
  magnetic 
  treatment. 
  The 
  

   analysis 
  has 
  been 
  supplied 
  by 
  Mr 
  Brakes.
