  very 
  curious 
  narrow 
  veins 
  of 
  garnet 
  cross 
  some 
  exposed 
  ledges. 
  

   They 
  suggest 
  metamorphosed 
  diabase 
  dikes. 
  

  

  Series 
  IV. 
  The 
  palaeozoic 
  sediments 
  are 
  entirely 
  lacking.

  One 
  small 
  diabase 
  dike 
  has 
  penetrated 
  the 
  

   anorthosites, 
  just 
  above 
  the 
  mill, 
  about 
  one 
  mile 
  west 
  of 
  the 
  

   Windsor 
  Hotel.

  The 
  surface 
  deposits 
  are 
  sands 
  and 
  gravels. 
  The 
  

   central 
  Eliza 
  bethtown 
  valley 
  is 
  a 
  beautiful 
  exhibition 
  of 
  an 
  

   abandoned 
  lake 
  bottom, 
  with 
  well-preserved 
  side 
  deltas. 
  It 
  has 
  

   been 
  described 
  by 
  my 
  assistant, 
  Mr. 
  Eies, 
  in 
  the 
  Trans. 
  'N. 
  Y.

  1893,

  The 
  water 
  was 
  clearly 
  held 
  in 
  

   check 
  by 
  a 
  drift 
  dam, 
  which 
  was 
  finally 
  cut 
  and 
  practically 
  all 
  

   eroded. 
  The 
  narrow 
  valley, 
  through 
  which 
  the 
  Boquet 
  river 
  

   makes 
  its 
  exit, 
  furnished 
  an 
  exceptionally 
  favorable 
  position 
  for 
  

   a 
  barrier. 
  The 
  old 
  deltas 
  are 
  of 
  wonderful 
  perfection, 
  and 
  at 
  the 
  

   time 
  of 
  our 
  visit 
  the 
  recent 
  freshet 
  exposed 
  them 
  in 
  ideal 
  cross- 
  

   sections. 
  Lincoln 
  pond 
  is 
  now 
  the 
  shrunken 
  remains 
  of 
  another 
  

   pleistocene 
  lake, 
  the 
  boundaries 
  of 
  which, 
  however, 
  we 
  have 
  not 
  

   traced. 
  

  

  Mines. 
  — 
  The 
  decline 
  of 
  the 
  blomaries 
  or 
  forges 
  proved 
  the 
  death- 
  

   blow 
  to 
  iron 
  mining 
  in 
  this 
  town, 
  except 
  at 
  the 
  Burt 
  Lot 
  mines, 
  

   which 
  are 
  just 
  within 
  its 
  southern 
  boundaries. 
  They, 
  however, 
  

   belong 
  with 
  the 
  Mineville 
  openings 
  and 
  are 
  worked 
  in 
  connection 
  

   with 
  them. 
  They 
  afford 
  a 
  rather 
  lean 
  bessemer 
  ore. 
  On 
  the 
  

   next 
  great 
  ridge, 
  to 
  the 
  northwest 
  of 
  Lincoln 
  pond, 
  is 
  a 
  line 
  of 
  

   openings, 
  of 
  which 
  the 
  Gates 
  and 
  Putnam 
  mines 
  are 
  the 
  largest. 
  

   They 
  are 
  in 
  pyroxene 
  gneiss 
  and 
  showed 
  good 
  sized 
  breasts 
  up 
  to 
  

   twenty 
  feet, 
  but 
  their 
  remote 
  situation 
  and 
  the 
  closing 
  down 
  of 
  

   the 
  New 
  Russia 
  blomary 
  ended 
  their 
  production. 
  Titaniferous 
  

   ores 
  are 
  known 
  in 
  several 
  places 
  in 
  the 
  eastern 
  anorthosite 
  area. 
  

   Along 
  the 
  western 
  edge 
  of 
  the 
  gneiss, 
  and 
  not 
  far 
  from 
  its 
  con- 
  

   tact 
  with 
  the 
  anorthosites 
  is 
  a 
  row 
  of 
  deposits 
  which 
  extend 
  both 
  

   north 
  and 
  south 
  of 
  New 
  Russia. 
  They 
  are 
  known 
  as 
  the 
  Ross? 
  

   Post, 
  Castaline 
  and 
  Pitkin 
  beds, 
  and 
  in 
  their 
  day 
  they 
  contributed 
  

   more 
  or 
  less 
  ore 
  to 
  the 
  New 
  Russia 
  forge 
  Mr. 
  Anthony 
  Ross 
  

   of 
  Essex, 
  owner 
  of 
  the 
  Ross' 
  bed, 
  informs 
  me 
  that 
  the 
  analysis 
  

   of 
  his 
  ore 
  showed 
  a 
  high 
  grade 
  of 
  bessemer. 
  The 
  remote 
  situa- 
  

   tion 
  will 
  prove 
  an 
  impassable 
  barrier 
  to 
  the 
  profitable 
  production 
  

   of 
  these 
  ores 
  for 
  many 
  years.
