  Several 
  points 
  brought 
  out 
  by 
  this 
  section 
  need 
  to 
  be 
  noted. 
  

   Vitreous 
  sandstones 
  run 
  up 
  in 
  it 
  for 
  nearly 
  60 
  feet 
  above 
  the 
  base, 
  

   and 
  there 
  may 
  be 
  some 
  question 
  in 
  regard 
  to 
  the 
  classification 
  of 
  

   this 
  portion 
  of 
  the 
  section. 
  The 
  sandstones 
  are 
  not 
  so 
  numerous 
  

   as 
  in 
  corresponding 
  portions 
  of 
  the 
  Theresa 
  section 
  elsewhere; 
  the 
  

   black 
  oolitic 
  and 
  magnesian 
  limestone 
  beds 
  are 
  quite 
  characteristic 
  

   of 
  the 
  Hoyt, 
  and 
  not 
  so 
  much 
  so 
  of 
  the 
  normal 
  Theresa. 
  The 
  sec- 
  

   tion 
  brings 
  out 
  clearly 
  the 
  fact 
  that 
  the 
  Hoyt 
  lies 
  above 
  the 
  Theresa 
  

   passage 
  beds 
  and 
  is 
  followed 
  by 
  the 
  Little 
  Falls 
  and 
  that 
  the 
  same 
  

   interval 
  elsewhere 
  is 
  occupied 
  by 
  a 
  thickness 
  of 
  passage 
  beds 
  equal 
  

   to 
  the 
  combined 
  thickness 
  of 
  the 
  Hoyt 
  and 
  Theresa 
  of 
  the 
  Sara- 
  

   toga 
  section. 
  In 
  other 
  words, 
  the 
  Hoyt 
  is 
  a 
  local 
  phase 
  of 
  the 
  upper 
  

   Theresa, 
  probably 
  a 
  more 
  offshore 
  phase. 
  It 
  is 
  exposed 
  only 
  at 
  

   Saratoga 
  because 
  only 
  here 
  has 
  erosion 
  cut 
  down 
  to 
  this 
  phase. 
  

   Elsewhere 
  the 
  near 
  shore 
  phase 
  of 
  the 
  formation 
  is 
  exposed 
  and
