  The 
  ore 
  in 
  places 
  is 
  a 
  compact 
  rich 
  magnetite, 
  yet 
  the 
  greater 
  por- 
  

   tion 
  as 
  exemplified 
  by 
  sampling 
  the 
  deposits 
  consists 
  of 
  disseminated 
  

   grains 
  or 
  stringers 
  of 
  magnetite 
  in 
  a 
  gangue 
  of 
  hornblende, 
  biotite 
  

   and 
  quartz. 
  Apatite 
  shows 
  in 
  some 
  specimens. 
  The 
  analyses, 
  

   however, 
  indicate 
  a 
  phosphorus 
  content 
  that 
  is 
  well 
  within 
  the 
  

   Bessemer 
  limits. 
  The 
  following 
  were 
  made 
  by 
  Mr 
  James 
  Brakes, 
  

   probably 
  from 
  selected 
  material.

  Battie 
  mine. 
  This 
  is 
  located 
  on 
  a 
  continuation 
  of 
  the 
  Cook 
  ore 
  

   body, 
  about 
  1 
  \ 
  miles 
  north 
  of 
  that 
  mine. 
  From 
  Emmons's 
  account, 
  

   the 
  existence 
  of 
  two 
  parallel 
  deposits 
  is 
  inferred, 
  though 
  only 
  one 
  

   is 
  shown 
  by 
  outcrop 
  or 
  workings. 
  The 
  mine 
  was 
  last 
  operated 
  

   about 
  50 
  years 
  ago. 
  It 
  is 
  an 
  open 
  cut 
  about 
  600 
  feet 
  long 
  and 
  10 
  to 
  

   20 
  feet 
  wide. 
  The 
  ore 
  shows 
  much 
  variation 
  across 
  the 
  dip, 
  bands 
  

   of 
  massive 
  magnetite 
  alternating 
  with 
  rock 
  that 
  carries 
  a 
  greater 
  

   or 
  smaller 
  proportion 
  of 
  magnetite 
  in 
  disseminated 
  grains. 
  It 
  has 
  

   a 
  sheeted 
  structure 
  evidently 
  due 
  to 
  slight 
  movements 
  along 
  the 
  

   walls. 
  They 
  are 
  noticeably 
  grooved 
  and 
  polished. 
  The 
  principal 
  

   gangue 
  mineral 
  is 
  biotite. 
  The 
  ore 
  is 
  said 
  to 
  have 
  yielded 
  good 
  

   iron, 
  similar 
  in 
  quality 
  to 
  that 
  made 
  from 
  the 
  Cook 
  ore. 
  Its 
  gen- 
  

   eral 
  character 
  is 
  shown 
  by 
  the 
  analyses 
  below 
  which 
  have 
  been 
  

   communicated 
  by 
  Mr 
  J. 
  N. 
  Stower. 
  The 
  analyses 
  were 
  made 
  by 
  

   James 
  Brakes 
  from 
  samples 
  taken 
  at 
  different 
  places 
  along 
  the 
  

   outcrop. 
  The 
  high 
  titanium, 
  reaching 
  over 
  2 
  per 
  cent 
  in 
  No. 
  5, 
  is
