  much 
  larger, 
  those 
  of 
  5 
  or 
  6 
  inches 
  in 
  diameter 
  being 
  very 
  common 
  

   and 
  the 
  largest 
  ones 
  taken 
  out 
  are 
  said 
  to 
  have 
  been 
  nearly 
  the 
  size 
  

   of 
  a 
  bushel 
  basket. 
  As 
  a 
  rule 
  the 
  hornblende 
  rims 
  increase 
  in 
  

   width 
  with 
  the 
  size 
  of 
  the 
  garnets, 
  and 
  the 
  large 
  garnets 
  imbedded 
  

   in 
  the 
  walls 
  of 
  this 
  mine 
  present 
  a 
  most 
  interesting 
  appearance. 
  

   The 
  garnet-bearing 
  hornblende 
  gneiss 
  here 
  forms 
  an 
  inclusion 
  in 
  

   syenite 
  fully 
  three-fourths 
  of 
  a 
  mile 
  long 
  and 
  200 
  feet 
  wide. 
  Several 
  

   large 
  openings 
  have 
  been 
  made 
  in 
  this 
  rock. 
  

  

  At 
  the 
  old 
  mine 
  on 
  the 
  Parker 
  farm 
  the 
  rocks 
  are 
  a 
  mixture 
  of 
  

   granitic 
  syenite 
  and 
  Grenville 
  interbanded 
  parallel 
  to 
  the 
  strike 
  

   of 
  the 
  foliation. 
  These 
  bands 
  of 
  rock 
  are 
  often 
  20 
  to 
  40 
  feet 
  wide, 
  

   one 
  of 
  them 
  being 
  made 
  up 
  of 
  a 
  nearly 
  pure, 
  granular, 
  medium 
  

   grained 
  mass 
  of 
  irregular 
  crystals 
  of 
  reddish 
  brown 
  garnet 
  and 
  

   bright 
  green 
  pyroxene 
  (coccolite?). 
  About 
  twenty 
  years 
  ago 
  this 
  

   band 
  of 
  garnet 
  rock 
  was 
  mined, 
  crushed, 
  and 
  put 
  into 
  barrels, 
  

   there 
  being 
  no 
  attempt 
  to 
  separate 
  the 
  pyroxene 
  from 
  the 
  garnet. 
  

  

  At 
  the 
  Sanders 
  Brothers 
  mine 
  the 
  mode 
  of 
  occurrence 
  is 
  very 
  

   similar 
  to 
  that 
  of 
  the 
  Parker 
  mine, 
  the 
  bands 
  of 
  Grenville 
  being, 
  

   however, 
  somewhat 
  less 
  pronounced 
  and 
  numerous. 
  The 
  rock 
  

   which 
  is 
  mined 
  is 
  quite 
  badly 
  granulated, 
  and 
  consists 
  mostly 
  of 
  

   intimately 
  associated 
  reddish 
  brown 
  garnet 
  and 
  green 
  pyroxene 
  

   (coccolite?) 
  in 
  small 
  grains, 
  with 
  sometimes 
  a 
  little 
  feldspar. 
  There 
  

   are 
  some 
  streaks 
  or 
  patches 
  of 
  nearly 
  pure 
  garnet. 
  Work 
  began 
  

   in 
  1907 
  on 
  the 
  south 
  side 
  of 
  the 
  creek 
  but 
  now 
  all 
  the 
  mining 
  is 
  

   confined 
  to 
  the 
  north 
  side 
  (see 
  map). 
  The 
  garnet, 
  pyroxene 
  rock 
  

   is 
  crushed, 
  put 
  into 
  bags, 
  and 
  shipped 
  to 
  various 
  parts 
  of 
  the 
  world. 
  

  

  'Years 
  ago 
  an 
  attempt 
  was 
  made 
  to 
  mine 
  the 
  garnets 
  which 
  occur 
  

   in 
  the 
  coarse, 
  feldspar, 
  biotite, 
  quartz, 
  garnet 
  (Grenville) 
  gneiss 
  

   about 
  three-fourths 
  of 
  a 
  mile 
  east 
  of 
  Fuller 
  pond. 
  

  

  At 
  the 
  Hooper 
  mine, 
  near 
  Thirteenth 
  lake, 
  the 
  garnets 
  occur 
  as 
  

   crystals, 
  often 
  with 
  good 
  crystal 
  boundaries, 
  up 
  to 
  an 
  inch 
  or 
  more 
  

   in 
  diameter. 
  They 
  are 
  thickly 
  scattered 
  through 
  a 
  medium 
  to 
  

   fairly 
  coarse-grained, 
  dark 
  to 
  light 
  gray, 
  very 
  gneissoid 
  horn- 
  

   blendic 
  rock 
  which 
  has 
  the 
  composition 
  of 
  a 
  basic 
  syenite 
  or 
  acidic 
  

   diorite. 
  These 
  garnets 
  never 
  show 
  the 
  rims 
  of 
  hornblende. 
  This 
  

   type 
  of 
  occurrence 
  has 
  not 
  been 
  noted 
  on 
  a 
  large 
  scale 
  within 
  the 
  

   map 
  limits 
  of 
  the 
  North 
  Creek 
  sheet, 
  though 
  a 
  rock 
  almost 
  exactly 
  

   like 
  it 
  does 
  occur 
  at 
  the 
  Rogers 
  mine 
  as 
  a 
  distinct 
  zone 
  (wall 
  rock) 
  

   intermediate 
  in 
  position 
  and 
  composition 
  between 
  the 
  typical 
  garnet 
  

   gneiss 
  and 
  the 
  country 
  rock 
  of 
  syenite, 
  where 
  the 
  garnet 
  rock 
  grades 
  

   perfectly 
  into 
  the 
  syenite.
