  It 
  is 
  interesting 
  to 
  note, 
  in 
  the 
  second 
  

   paper, 
  the 
  rapid 
  discerning 
  in 
  Alberta 
  of 
  "Lower 
  Cretaceous" 
  

   formations, 
  and 
  that 
  their 
  fossils 
  indicate 
  a 
  sea 
  that 
  "probably 
  

   came 
  in 
  from 
  the 
  north 
  or 
  northeast." 
  The 
  seaway 
  is, 
  there- 
  

   fore, 
  not 
  a 
  transgression 
  from 
  the 
  Pacific 
  eastward 
  across 
  Canada 
  

   into 
  Alberta. 
  What 
  the 
  relations 
  of 
  these 
  Comanchean 
  forma- 
  

   tions 
  are 
  to 
  the 
  Kootenay

  not 
  yet

  It

  interesting 
  to

  that 
  something 
  

   of 
  the 
  Upper 
  Devonian 
  Portage 
  fauna 
  of 
  New

  species) 
  

   occurs 
  in 
  the

  the

  that 
  

   it

  by 
  that

  Spirifer

  the

  This 
  paper 
  sets 
  forth 
  something 
  of 
  the 
  evolution 
  of 
  

   American 
  Exogyras, 
  with 
  the 
  statement 
  that 
  "all 
  of 
  the 
  [Ameri- 
  

   can] 
  species, 
  even 
  the 
  largest 
  which 
  are 
  practically 
  smooth, 
  came 
  

   originally 
  from 
  a 
  rather 
  small 
  costate 
  form." 
  The 
  new 
  species 
  

   is 
  E. 
  cartledgei, 
  but 
  the 
  young 
  stages 
  of 
  E. 
  arietina 
  Roemer 
  are 
  

   also 
  described.

  The 
  great 
  desideratum 
  that 
  many 
  workers 
  should 
  take 
  up 
  

   the 
  problems 
  of 
  sedimentation 
  is 
  being 
  voiced 
  more 
  and 
  more. 
  

   The 
  author 
  here 
  points 
  out 
  some 
  of 
  the 
  things 
  that 
  are 
  being 
  

   done 
  and 
  that 
  should 
  be 
  done 
  along 
  this 
  line. 
  The 
  field 
  of 
  

   endeavor 
  is 
  great 
  and 
  many 
  young 
  enthusiasts 
  are 
  needed.
