  'Examples 
  of 
  the 
  

   first 
  group 
  are 
  found 
  in 
  the 
  

   folded 
  region 
  in 
  the 
  eastern 
  part 
  

   of 
  the 
  State 
  where 
  the 
  long 
  nar- 
  

   row 
  strips 
  of 
  Lower 
  Cambric, 
  

   especially 
  north 
  of 
  the 
  Hoosic 
  

   river, 
  represent, 
  according 
  to 
  the 
  

   present 
  conception 
  of 
  the 
  struc- 
  

   ture 
  of 
  this 
  region, 
  more 
  or 
  less 
  

   complex 
  anticlines.^ 
  The 
  Cam- 
  

   bric 
  is 
  here 
  surrounded 
  or 
  

   thought 
  to 
  protrude 
  from 
  Lower 
  

   Siluric 
  rocks. 
  This 
  conception 
  is 
  

   shown 
  in 
  Dale's 
  section 
  of 
  the 
  

   north 
  end 
  of 
  the 
  Taconic 
  range. 
  

   It 
  is, 
  however, 
  possible 
  that 
  the 
  

   relations 
  of 
  the 
  Cambric 
  to 
  the 
  

   Lower 
  Siluric 
  are 
  greatly 
  dif- 
  

   ferent 
  in 
  the 
  slate 
  belt 
  and 
  we 
  

   will 
  recur 
  to 
  this 
  point 
  under 
  

   the 
  heading 
  of 
  overthrust 
  inliers 
  

   [sec 
  p. 
  188]. 
  To 
  find 
  undoubted 
  

   macroanticlinal 
  inliers 
  we 
  have 
  

   to 
  go 
  outside 
  of 
  the 
  State, 
  to 
  

   the 
  northern 
  extension 
  of 
  our 
  

   folded 
  regions, 
  to 
  \'ermont, 
  and 
  

   to 
  the 
  Allegheny 
  mountains. 
  

   Here 
  are 
  long 
  belts 
  of 
  Cam- 
  

   bric 
  rocks 
  inclosed 
  by 
  the 
  Lower 
  

   Siluric 
  areas 
  and
