  Eight 
  miles 
  south 
  of 
  the 
  above 
  section 
  and 
  i^ 
  miles 
  north- 
  

   west-north 
  of 
  Lyons 
  Falls 
  station 
  another 
  excellent 
  section 
  is 
  

   shown 
  along 
  Mill 
  creek 
  where 
  all 
  the 
  beds 
  from 
  the 
  Precambric 
  

   to 
  the 
  Trenton 
  are 
  exposed. 
  Mill 
  creek 
  is 
  not 
  properly 
  placed 
  

   on 
  the 
  map 
  here. 
  Its 
  true 
  course 
  is 
  close 
  to 
  the 
  town 
  line 
  be- 
  

   tween 
  Turin 
  and 
  West 
  Turin. 
  By 
  means 
  of 
  the 
  hand 
  level 
  the 
  

   writer 
  has 
  determined 
  the 
  thickness 
  of 
  the 
  Pamelia 
  here 
  to 
  be 
  

   about 
  56 
  feet. 
  The 
  basal 
  conglomerate, 
  i 
  foot 
  thick, 
  is 
  followed 
  

   by 
  10 
  feet 
  of 
  gray, 
  calcareous 
  sandstones 
  and 
  very 
  sandy 
  lime- 
  

   stones 
  with 
  some 
  sandy 
  shale 
  partings. 
  Next 
  come 
  4^ 
  feet 
  of 
  

   bluish 
  black 
  limestones. 
  Above 
  this 
  the 
  beds 
  are 
  much 
  like 
  

   those 
  along 
  Roaring 
  brook 
  and 
  their 
  summit 
  is 
  here 
  also 
  capped 
  

   by 
  a 
  limestone 
  conglomerate. 
  

  

  Some 
  7 
  miles 
  south 
  of 
  the 
  Mill 
  creek 
  section 
  and 
  in 
  the 
  vicin- 
  

   ity 
  of 
  Denley 
  there 
  are 
  good 
  exposures 
  of 
  the 
  Pamelia. 
  No 
  

   complete 
  section 
  is 
  visible 
  but 
  a 
  study 
  of 
  all 
  the 
  outcrops 
  makes 
  

   it 
  certain 
  that 
  the 
  formation 
  is 
  here 
  not 
  over 
  20 
  feet 
  thick. 
  The 
  

   basal 
  conglomerate 
  and 
  sandstone 
  underlies 
  grayish, 
  sandy, 
  thick 
  

   bedded 
  limestones, 
  while 
  the 
  whole 
  is 
  capped 
  by 
  the 
  usual 
  lime- 
  

   stone 
  conglomerate. 
  The 
  most 
  southerly 
  outcrops 
  of 
  Pamelia 
  

   occur 
  along 
  Mile 
  creek 
  from 
  ^ 
  to 
  i 
  mile 
  above 
  its 
  mouth, 
  where 
  

   the 
  formation 
  is 
  apparently 
  not 
  over 
  10 
  of 
  12 
  feet 
  thick. 
  It 
  dis- 
  

   appears 
  before 
  the 
  Remsen 
  quadrangle 
  is 
  reached. 
  

  

  The 
  thinning 
  out 
  to 
  disappearance 
  of 
  the 
  Pamelia 
  in 
  passing 
  

   southeasterly 
  may 
  be 
  entirely 
  explained 
  as 
  due 
  to 
  overlap, 
  since 
  

   the 
  formation 
  came 
  in 
  from 
  the 
  west, 
  as 
  above 
  shown, 
  and 
  rap- 
  

   idly 
  thins 
  out 
  eastward. 
  Its 
  place 
  of 
  disappearance, 
  most 
  likely 
  

   in 
  the 
  northeastern 
  corner 
  of 
  the 
  Boonville 
  quadrangle, 
  is 
  some 
  

   9 
  or 
  10 
  miles 
  east 
  of 
  a 
  north-south- 
  line 
  passing 
  through 
  the 
  

   Roaring 
  brook 
  section 
  where 
  the 
  Pamelia 
  is 
  over 
  71 
  feet 
  thick. 
  

   This 
  represents 
  an 
  eastward 
  thinning 
  of 
  7 
  or 
  8 
  feet 
  per 
  mile 
  

   which 
  compares 
  favorably 
  wath 
  the 
  rate 
  of 
  thinning 
  noted 
  by 
  

   Gushing 
  over 
  the 
  Theresa 
  quadrangle. 
  Of 
  course, 
  some 
  of 
  the 
  

   thinning 
  may 
  quite 
  possibly 
  be 
  due 
  to 
  a 
  lack 
  of 
  deposition 
  of 
  so 
  

   much 
  material 
  in 
  the 
  southern 
  portion 
  of 
  the 
  basin. 
  It 
  seems 
  

   certain 
  that 
  the 
  Pamelia 
  is 
  present 
  in 
  considerable 
  force, 
  under 
  

   cover 
  of 
  later 
  rocks, 
  in 
  the 
  western 
  part 
  of 
  the 
  Port 
  Leyden 
  

   quadrangle 
  and 
  to 
  some 
  extent, 
  at 
  least, 
  in 
  the 
  northern 
  part 
  of 
  

   the 
  Boonville 
  quadrangle. 
  In 
  a 
  letter 
  Gushing 
  says 
  that 
  what 
  

   has 
  heretofore 
  been 
  referred 
  to 
  as 
  Beekmantown-Lowville 
  passage 
  

   beds 
  in 
  the 
  region 
  around 
  Little 
  Falls 
  may 
  in 
  reality 
  be 
  a 
  touch 
  of 
  

   the 
  PameHa 
  there.
