  Series 
  2. 
  We 
  have 
  secured 
  record 
  of 
  the 
  white 
  crystalline 
  lime- 
  

   stone 
  at 
  only 
  two 
  points. 
  One 
  is 
  at 
  the 
  steamer 
  dock 
  at 
  Sabbath- 
  

   day 
  Point, 
  where 
  at 
  low 
  water 
  it 
  is 
  stated, 
  limestone 
  is 
  exposed. 
  

   The 
  other 
  is 
  in 
  a 
  deep 
  boring 
  at 
  the 
  new 
  prospect 
  at 
  Graphite, 
  

   where 
  Mr 
  Frank 
  Hooper 
  informed 
  us 
  that 
  limestone 
  was 
  

   penetrated 
  30 
  feet 
  below 
  the 
  surface. 
  The 
  limestones 
  also 
  occur 
  

   at 
  Rogers 
  Rock, 
  but 
  whether 
  in 
  Hague 
  or 
  Ticonderoga 
  or 
  both 
  

   we 
  can 
  not 
  say. 
  

  

  In 
  Hague 
  township 
  there 
  are 
  however 
  the 
  most 
  interesting 
  

   metamorphosed 
  sediments 
  of 
  Precambrian 
  age 
  that 
  have 
  yet 
  been 
  

   met 
  in 
  the 
  eastern 
  mountains. 
  The 
  principal 
  outcrop 
  and 
  the 
  

   one 
  best 
  exposed 
  is 
  at 
  the 
  graphite 
  mine 
  about 
  four 
  miles 
  west 
  

   of 
  Hague 
  village, 
  but 
  other 
  rocks 
  which 
  are 
  with 
  little 
  doubt 
  

   altered 
  sediments 
  are 
  met 
  at 
  several 
  other 
  points 
  in 
  the 
  town. 
  

   The 
  graphite 
  deposit 
  will 
  be 
  first 
  taken 
  up 
  and 
  then 
  the 
  others. 
  

   The 
  graphitic 
  deposit 
  is 
  an 
  impregnation 
  or 
  dissemination 
  of 
  

   graphite 
  in 
  quartzite. 
  The 
  graphite 
  forms 
  leafy 
  masses 
  among 
  

   the 
  grains 
  of 
  quartz 
  and 
  seemed 
  to 
  lie 
  along 
  slipping 
  surfaces 
  

   which 
  have 
  rubbed 
  them 
  out 
  into 
  small 
  striae. 
  Beyond 
  question 
  

   there 
  has 
  been 
  movement 
  in 
  the 
  rocks 
  of 
  a 
  most 
  pronounced 
  

   character 
  and 
  they 
  have 
  -been 
  squeezed 
  and 
  maehed 
  with 
  a 
  elid- 
  

   ing 
  along 
  the 
  bedding. 
  The 
  quartz 
  contains 
  a 
  good 
  many 
  email 
  

   apatites 
  and 
  probably 
  zircons 
  and 
  rarely 
  shreds 
  of 
  biotite, 
  but 
  

   iu 
  the 
  large 
  way 
  there 
  is 
  little 
  else 
  than 
  quartz 
  and 
  graphite 
  

   present. 
  This 
  simplifies 
  the 
  problem 
  of 
  concentrating 
  the 
  

   graphite, 
  with 
  which 
  any 
  scaly 
  mineral 
  would 
  interfere. 
  The 
  

   foot 
  and 
  hanging 
  walls 
  are 
  a 
  tough, 
  dense, 
  green, 
  garnetiferous 
  

   gneiss, 
  a 
  peculiar 
  rock 
  that 
  has 
  not 
  been 
  noted 
  elsewhere. 
  Large 
  

   red 
  garnets 
  up 
  to 
  half 
  an 
  inch 
  in 
  diameter 
  are 
  buried 
  in 
  the 
  

   greenish, 
  fibrous 
  matrix. 
  In 
  appearance 
  the 
  rock 
  suggests 
  some- 
  

   what 
  the 
  eclogites 
  of 
  Bavaria, 
  but 
  in 
  thin 
  section 
  the 
  hanging 
  

   wall 
  is 
  found 
  to 
  be 
  almost 
  entirely 
  sillimanite 
  and 
  garnet 
  {see 
  

   plate 
  10, 
  fig. 
  A 
  and 
  B). 
  There 
  is 
  a 
  little 
  quartz 
  and 
  more 
  or 
  less 
  

   graphite, 
  and 
  some 
  small 
  accessories, 
  but 
  other 
  minerals 
  are 
  lack- 
  

   ing. 
  The 
  sillimanite 
  forms 
  fibrous 
  aggregates 
  with 
  roughly 
  

   parallel 
  alignment 
  and 
  of 
  size 
  from 
  very 
  fine 
  rods 
  up 
  to 
  prisms 
  

   ^l 
  of 
  an 
  inch 
  (1 
  mm) 
  in 
  diameter. 
  It 
  is 
  broken 
  by 
  the 
  cross 
  frac-
