  Section 
  No. 
  2 
  was 
  run 
  268 
  feet 
  south 
  of 
  No. 
  1 
  or 
  middle 
  

   section 
  and 
  gave 
  a 
  width 
  of 
  610 
  feet 
  of 
  ore 
  without 
  apparently 
  

   encountering 
  the 
  walls. 
  Section 
  No. 
  3 
  crossed 
  the 
  ore 
  body 
  210 
  

   feet 
  south 
  of 
  No. 
  2, 
  and 
  No. 
  4 
  was 
  run 
  231 
  feet 
  north 
  of 
  No. 
  1; 
  

   their 
  length 
  is 
  not 
  stated. 
  On 
  the 
  basis 
  of 
  this 
  work 
  Professor 
  

   Emmons 
  estimated 
  the 
  ore 
  body 
  to 
  contain 
  6,830,000 
  tons 
  at 
  a 
  

   depth 
  of 
  2 
  feet 
  below 
  the 
  adjoining 
  surface. 
  The 
  results 
  obtained 
  

   by 
  diamond 
  drilling 
  during 
  the 
  years 
  1906 
  and 
  1907 
  have 
  demon- 
  

   strated 
  that 
  the 
  ore 
  continues 
  westward 
  practically 
  to 
  the 
  lake 
  

   side 
  considerably 
  farther 
  than 
  Emmons 
  was 
  able 
  to 
  trace 
  it, 
  wmile 
  

   they 
  have 
  also 
  proved 
  its 
  continuity 
  to 
  a 
  depth 
  of 
  300 
  or 
  400 
  feet, 
  

   as 
  far 
  as 
  the 
  drills 
  have 
  penetrated. 
  Recent 
  magnetic 
  surveys 
  

   show 
  the 
  existence 
  of 
  lines 
  of 
  attraction 
  which 
  cross 
  the 
  lake 
  to 
  

   the 
  western 
  shore 
  where 
  they 
  merge 
  with 
  the 
  smaller 
  ore 
  body
