  — 
  Seasonal 
  deposition 
  in 
  aqueo-glacial 
  deposits 
  has 
  been 
  a 
  

   subject 
  of 
  much 
  interest 
  since 
  de 
  Greer 
  succeeded 
  in 
  counting 
  by 
  

   that 
  means 
  twelve 
  thousand 
  years 
  of 
  late 
  glacial 
  and 
  post-glacial 
  

   time. 
  Deposition 
  of 
  the 
  coarser 
  sediment 
  near 
  the 
  ice-front 
  is 
  

   very 
  much 
  increased 
  during 
  the 
  melting 
  season. 
  As 
  a 
  result 
  

   the 
  clay 
  deposits 
  in 
  water 
  bodies 
  marginal 
  to 
  ice 
  sheets 
  are 
  

   banded 
  as 
  conspicuously 
  as 
  the 
  annual 
  rings 
  of 
  growth 
  in 
  trees. 
  

   Sayles 
  some 
  years 
  ago 
  published 
  descriptions 
  of 
  his 
  discoveries 
  

   of 
  striated 
  bowlders 
  and 
  other 
  evidences 
  of 
  glacial 
  origin 
  in 
  the 
  

   Squantum 
  tillite 
  member 
  of 
  the 
  Roxbury 
  conglomerate 
  series 
  of 
  

   Permo-Carboniferous 
  age 
  near 
  Boston, 
  Massachusetts. 
  

  

  The 
  present 
  memoir 
  is 
  a 
  very 
  careful 
  study 
  of 
  the 
  banded 
  

   slates 
  which 
  occur 
  interbedded 
  with 
  the 
  tillite. 
  The 
  plates 
  show 
  

   handsome 
  reproductions 
  of 
  banding 
  in 
  Pleistocene 
  clays 
  com- 
  

   pared 
  with 
  the 
  Squantum 
  banded 
  argillites. 
  The 
  resemblance 
  is 
  

   striking. 
  The 
  memoir 
  is 
  important 
  not 
  only 
  in 
  giving 
  further 
  

   evidence 
  of 
  the 
  glacial 
  associations 
  of 
  the 
  Roxbury 
  conglomerate 
  

   Series, 
  but 
  in 
  proving 
  the 
  existence 
  of 
  sharp 
  seasonal 
  changes 
  

   from 
  summer 
  to 
  winter 
  at 
  that 
  time 
  and 
  in 
  that 
  latitude. 
  Fur- 
  

   thermore 
  the 
  bands 
  give 
  graphic 
  detail 
  of 
  individual 
  years. 
  As 
  

   a 
  meteorological 
  record 
  belonging 
  to 
  a 
  remote 
  geologic 
  period 
  

   Sayles' 
  publication 
  is 
  unique.
