  In 
  Erie 
  county 
  on 
  the 
  western 
  end 
  of 
  the 
  belt 
  the 
  dip 
  of 
  the 
  

   Upper 
  Siluric 
  strata 
  has 
  usually 
  been 
  estimated 
  at 
  50 
  feet 
  or 
  less 
  

   to 
  the 
  mile. 
  The 
  Clinton 
  outcrop, 
  however, 
  here 
  lies 
  fully 
  150 
  feet 
  

   higher 
  with 
  respect 
  to 
  sea 
  level 
  than 
  it 
  does 
  in 
  the 
  central 
  part, 
  

   a 
  circumstance 
  that 
  seems 
  to 
  indicate 
  a 
  higher 
  rate 
  of 
  inclination 
  

   than 
  the 
  above, 
  when 
  it 
  is 
  further 
  considered 
  that 
  the 
  line 
  of 
  out- 
  

   crop 
  is 
  somewhat 
  south 
  of 
  its 
  position 
  in 
  Wayne 
  and 
  Cayuga 
  coun- 
  

   ties. 
  At 
  Rochester 
  the 
  dip 
  has 
  been 
  stated 
  at 
  80 
  feet 
  to 
  the 
  mile, 
  

   in 
  a 
  direction 
  slightly 
  east 
  of 
  south. 
  

  

  On 
  the 
  eastern 
  section 
  of 
  the 
  belt 
  the 
  dips 
  increase 
  progressively 
  

   from 
  Madison 
  to 
  Herkimer 
  county, 
  while 
  there 
  is 
  likewise 
  a 
  grad- 
  

   ual 
  increase 
  of 
  elevation 
  of 
  the 
  outcrop. 
  The 
  average 
  dip, 
  as 
  

   determined 
  from 
  the 
  Chittenango 
  and 
  Lakeport 
  wells, 
  in 
  Madison 
  

   county, 
  is 
  62 
  feet 
  to 
  the 
  mile 
  over 
  a 
  distance 
  of 
  8 
  miles. 
  The 
  dip 
  

   of 
  the 
  iron 
  ore 
  at 
  Clinton 
  as 
  determined 
  by 
  leveling 
  is 
  150 
  ieet 
  

   to 
  the 
  mile. 
  There 
  is 
  little 
  basis 
  for 
  calculation 
  of 
  the 
  dips 
  in 
  the 
  

   part 
  of 
  the 
  belt 
  beyond 
  Oneida 
  county, 
  but 
  it 
  is 
  to 
  be 
  expected 
  

   naturally 
  that 
  the 
  beds 
  are 
  more 
  highly 
  inclined 
  as 
  they 
  come 
  more 
  

   and 
  more 
  within 
  the 
  zone 
  of 
  the 
  Appalachian 
  uplift. 
  

  

  It 
  is 
  in 
  this 
  region 
  that 
  the 
  Clinton 
  outcrop 
  reaches 
  its 
  highest 
  

   elevation 
  which 
  is 
  about 
  1400 
  feet. 
  At 
  Clinton 
  the 
  elevation 
  is 
  about 
  

   700 
  feet. 
  In 
  eastern 
  Wayne 
  county 
  the 
  iron 
  ore 
  bed 
  lies 
  at 
  nearly 
  

   the 
  level 
  of 
  Lake 
  Ontario 
  which 
  is 
  246 
  feet. 
  In 
  Niagara 
  county 
  the 
  

   northern 
  outcropping 
  edge 
  of 
  the 
  Clinton 
  is 
  found 
  at 
  about 
  400 
  

   feet. 
  

  

  A 
  comparison 
  of 
  the 
  dips 
  given 
  above 
  shows 
  that 
  the 
  uplifting 
  of 
  

   the 
  beds 
  has 
  been 
  accompanied 
  by 
  a 
  certain 
  amount 
  of 
  warping, 
  the 
  

   effect 
  of 
  which 
  has 
  been 
  to 
  give 
  the 
  formation 
  as 
  a 
  whole 
  a 
  broad 
  

   synclinal 
  arrangement, 
  with 
  the 
  depressed 
  portion 
  in 
  the 
  central 
  

   part 
  near 
  the 
  Wayne-Cayuga 
  county 
  line, 
  where 
  the 
  beds 
  attain 
  their 
  

   most 
  northerly 
  extent 
  within 
  the 
  State. 
  East 
  of 
  this 
  line 
  the 
  gen- 
  

   eral 
  dip 
  is 
  toward 
  the 
  southwest, 
  becoming 
  more 
  marked 
  as 
  the 
  

   eastern 
  termination 
  is 
  approached. 
  Between 
  Cayuga 
  and 
  Monroe 
  

   counties 
  the 
  dip 
  is 
  slightly 
  east 
  of 
  south. 
  West 
  of 
  Monroe 
  county 
  

   the 
  syncline 
  appears 
  to 
  be 
  interrupted 
  by 
  a 
  minor 
  undulation, 
  indi- 
  

   cated 
  by 
  the 
  southwesterly 
  dip 
  of 
  the 
  beds 
  at 
  Niagara 
  Falls.

  The 
  name 
  Protean 
  originally 
  applied 
  to 
  the 
  Clinton 
  beds 
  by 
  Van- 
  

   uxem 
  is 
  significant 
  of 
  their 
  extreme 
  variability. 
  They 
  comprise 
  a 
  

   heterogeneous 
  assemblage 
  of 
  sedimentary 
  types
