  The 
  crystalline 
  limestone 
  series 
  certainly 
  is, 
  and 
  

   has 
  been 
  so 
  colored 
  by 
  Walcott 
  in 
  a 
  small 
  map 
  of 
  the 
  United 
  States. 
  

   (U. 
  S. 
  Geol. 
  Surv. 
  Bulletin, 
  Plate 
  II, 
  p. 
  865.) 
  The 
  magnetites 
  

   occur 
  in 
  gneisses 
  as 
  fundamental 
  as 
  any, 
  and 
  these 
  gneisses 
  show 
  

   more 
  or 
  less 
  mineralogical 
  variety. 
  Such 
  ores 
  and 
  variable 
  gneisses 
  

   are 
  thought 
  to 
  characterize 
  the 
  Grenville 
  series 
  in 
  Canada 
  while 
  

   the 
  Ottawa 
  gneiss 
  is 
  Very 
  uniform 
  and 
  lacks 
  ore 
  entirely.

  Hise 
  

   regards 
  the 
  G-renville 
  series 
  as 
  Algonkian.

  Whether, 
  therefore 
  any 
  gneiss 
  has 
  been 
  yet 
  

   met 
  in 
  this 
  district 
  which 
  would 
  be 
  regarded 
  archsean 
  in 
  the 
  

   sense 
  of 
  Yan 
  Hise, 
  or 
  which 
  would 
  correspond 
  to 
  the 
  Ottawa 
  

   gneiss 
  of 
  the 
  Canadian 
  geologists, 
  is 
  doubtful. 
  Dr. 
  Smyth, 
  

   however, 
  has 
  perhaps 
  met 
  these 
  older 
  gneisses 
  on 
  the 
  western 
  side, 
  

   as 
  they 
  are 
  there 
  more 
  uniform 
  and 
  lack 
  magnetites.

  Series 
  I. 
  The 
  gneisses 
  make 
  up 
  the 
  largest 
  portion 
  of 
  Ticon- 
  

   deroga. 
  Th^y 
  enter 
  from 
  Warren 
  county 
  on 
  the 
  south 
  as 
  high 
  

   ridges 
  with 
  a 
  northeast 
  trend. 
  They 
  probably 
  form 
  the 
  western 
  

   part 
  of 
  the 
  town, 
  but 
  the 
  area 
  is 
  a 
  wild 
  region 
  and 
  can 
  best 
  be 
  

   reached 
  from 
  the 
  west 
  another 
  season. 
  The 
  strike 
  of 
  the 
  lamina- 
  

   tions 
  in 
  Ticonderoga 
  village 
  is 
  north 
  thirty 
  degrees 
  east, 
  but 
  in 
  

   the 
  ridge 
  west 
  of 
  Lake 
  George 
  it 
  is 
  north 
  forty 
  degrees 
  west. 
  Fur- 
  

   tier 
  north 
  it 
  changes 
  to 
  the 
  east 
  again 
  and 
  near 
  Putnam's 
  pond 
  is 
  

   variable 
  through 
  ninety 
  degrees, 
  but 
  has 
  a 
  general 
  northerly 
  trend.
