  to 
  12 
  feet 
  wide, 
  with 
  an 
  extreme 
  depth 
  of 
  ioo 
  feet. 
  In 
  its 
  associa- 
  

   tion 
  and 
  nature 
  the 
  ore 
  is 
  much 
  the 
  same 
  as 
  the 
  Palmer 
  hill 
  ore 
  and 
  

   it 
  is 
  said 
  to 
  have 
  yielded 
  equally 
  good 
  iron. 
  

  

  Dills 
  & 
  Lavake 
  and 
  Rutgers 
  pits. 
  The 
  openings 
  are 
  situated 
  3 
  

   miles 
  north 
  of 
  Palmer 
  hill 
  at 
  an 
  elevation 
  of 
  about 
  1400 
  feet, 
  as 
  

   nearly 
  as 
  can 
  be 
  determined. 
  They 
  are 
  just 
  without 
  the 
  limits 
  of 
  

   the 
  Ausable 
  topographic 
  sheet. 
  The 
  Dills 
  & 
  Lavake 
  is 
  an 
  open 
  cut 
  

   100 
  feet 
  long 
  and 
  15 
  feet 
  wide. 
  The 
  Rutgers 
  pit 
  north 
  of 
  this 
  is 
  

   nearly 
  circular, 
  30 
  feet 
  in 
  diameter 
  and 
  about 
  that 
  in 
  depth. 
  The 
  

   ore 
  is 
  somewhat 
  richer 
  than 
  the 
  average 
  for 
  Palmer 
  hill. 
  It 
  con- 
  

   tains 
  apatite 
  in 
  plainly 
  visible 
  grains, 
  indicating 
  a 
  high 
  phosphorus 
  

   content. 
  The 
  following 
  incomplete

  Cook 
  mine. 
  On 
  the 
  ridge 
  east 
  of 
  Arnold 
  hill 
  the 
  gneiss 
  series 
  is 
  

   well 
  exposed. 
  Much 
  of 
  it 
  is 
  the 
  reddish 
  microperthitic 
  nearly 
  mas- 
  

   sive 
  variety 
  that 
  has 
  been 
  described 
  as 
  the 
  predominant 
  formation 
  

   of 
  the 
  district, 
  but 
  there 
  is 
  less 
  augite 
  and 
  oftentimes 
  very 
  little 
  

   quartz 
  present. 
  In 
  the 
  vicinity 
  of 
  the 
  Cook 
  mine 
  the 
  dark 
  constitu- 
  

   ent 
  is 
  biotite 
  and 
  the 
  rock 
  has 
  the 
  composition 
  of 
  syenite. 
  A 
  coarse 
  

   quart 
  zose 
  hornblende 
  variety, 
  which 
  looks 
  like 
  a 
  sheared 
  granite, 
  

   is 
  found 
  in 
  small 
  patches 
  that 
  may 
  represent 
  later 
  intrusions; 
  it 
  

   has 
  a 
  fresher 
  appearance 
  than 
  the 
  syenite 
  and 
  the 
  borders 
  are 
  com- 
  

   monly 
  pegmatitic. 
  

  

  The 
  Cook 
  mine, 
  mentioned 
  by 
  Emmons 
  as 
  having 
  been 
  exploited 
  

   several 
  years 
  before 
  the 
  date 
  of 
  his 
  report, 
  supplied 
  ore 
  to 
  forges 
  

   on 
  the 
  Little 
  Ausable. 
  It 
  was 
  last 
  worked 
  in 
  1856 
  when 
  the 
  forges 
  

   were 
  carried 
  away 
  by 
  a 
  flood. 
  Two 
  pits 
  evidence 
  these 
  early 
  opera- 
  

   tions. 
  They 
  are 
  situated 
  on 
  the 
  western 
  side 
  of 
  the 
  ridge 
  nearly 
  

   opposite 
  the 
  Nelson 
  Bush 
  shafts 
  on 
  Arnold 
  hill. 
  The 
  elevation 
  is 
  

   about 
  1000 
  feet. 
  Both 
  are 
  surface 
  strippings, 
  of 
  which 
  the 
  larger 
  

   exposes 
  a 
  breast 
  of 
  ore 
  about 
  12 
  feet 
  from 
  wall 
  to 
  wall. 
  They 
  have 
  

   a 
  north 
  strike 
  and 
  a 
  dip 
  8o° 
  west. 
  The 
  smaller 
  parallel 
  pit 
  lies 
  above 
  

   separated 
  by 
  30 
  feet 
  of 
  rock. 
  Emmons 
  records 
  that 
  in 
  exploring 
  

   the 
  deposit 
  by 
  a 
  transverse 
  trench 
  four 
  veins 
  were 
  encountered 
  

   with 
  thicknesses 
  of 
  2 
  feet, 
  3 
  feet, 
  6 
  feet 
  and 
  13 
  feet 
  respectively.
