  Generally 
  speaking, 
  the 
  streams 
  which 
  enter 
  the 
  lake 
  from 
  the 
  

   east 
  side 
  are 
  smaller 
  and 
  other 
  conditions 
  for 
  delta 
  construction 
  are 
  

   very 
  much 
  less 
  favorable, 
  than 
  on 
  the 
  west 
  side. 
  However, 
  topo- 
  

   graphic 
  configurations 
  closely 
  resembling 
  deltas 
  of 
  very 
  imperfect 
  

   formation 
  are 
  seen 
  along 
  the 
  east 
  side 
  streams 
  all 
  the 
  way 
  for 
  a 
  

   distance 
  of 
  some 
  three 
  to 
  five 
  miles 
  north 
  of 
  Hammondsport. 
  

  

  Delta 
  forms 
  are 
  also 
  seen 
  along 
  the 
  following 
  streams 
  entering 
  

   Canandaigua 
  lake 
  from 
  the 
  west 
  side, 
  and 
  are 
  placed 
  approximately 
  

   at 
  the 
  Newberry 
  level 
  : 
  Lapham's 
  glen, 
  two 
  and 
  one 
  half 
  miles 
  

   north 
  of 
  Naples 
  ; 
  the 
  stream 
  entering 
  at 
  Seneca 
  point 
  landing 
  ; 
  

   Victoria 
  glen, 
  one 
  and 
  one 
  half 
  miles 
  north 
  of 
  Seneca 
  point 
  land- 
  

   ing 
  ; 
  and 
  on 
  Menteiths 
  creek 
  which 
  enters 
  some 
  eight 
  miles 
  north 
  

   from 
  the 
  head 
  of 
  the 
  lake. 
  

  

  Comparative 
  strength

  the

  of 
  the

   terraces. 
  The 
  shore 
  features 
  found 
  marking 
  the 
  Newberry 
  level 
  when 
  

   considered 
  collectively, 
  are 
  the 
  largest 
  and 
  therefore 
  more 
  strongly 
  

   defined 
  in 
  development 
  than 
  any 
  single 
  set 
  which 
  mark 
  the 
  level 
  

   of 
  any 
  one 
  of 
  the 
  other 
  lake 
  stages.

  The 
  stronger 
  development 
  of 
  the 
  Newberry 
  terraces 
  over 
  those 
  

   of 
  any 
  other 
  stage 
  would 
  suggest 
  one 
  of 
  two 
  conditions 
  prevailing 
  at 
  

   the 
  time 
  of 
  formation. 
  First, 
  that 
  this 
  level 
  was 
  held 
  for 
  a 
  longer 
  

   period 
  of 
  time 
  than 
  any 
  previous 
  or 
  subsequent 
  one 
  thus 
  far 
  studied, 
  

   during 
  w^hich 
  the 
  activity 
  of 
  the 
  streams, 
  in 
  the 
  transportation 
  and 
  

   deposition 
  of 
  material 
  while 
  no 
  greater 
  than 
  for 
  any 
  other 
  period, 
  

   enabled 
  the 
  streams 
  to 
  accomplish 
  a 
  greater 
  amount 
  of 
  work. 
  Or, 
  

   second, 
  that 
  the 
  time 
  limit, 
  being 
  no 
  greater 
  than 
  for 
  any 
  pre- 
  

   vious 
  or 
  subsequent 
  stage, 
  the 
  agencies 
  concerned 
  in 
  the 
  processes 
  

   of 
  collecting 
  (erosion), 
  transportation 
  and 
  deposition 
  of 
  materials 
  

   were 
  more 
  vigorous, 
  and 
  attained 
  a 
  very 
  much 
  greater 
  degree 
  of 
  

   activity 
  than 
  for 
  any 
  one 
  of 
  the 
  other 
  periods. 
  

  

  When 
  considered 
  singly, 
  neither 
  of 
  the 
  two 
  possibilities 
  here 
  

   offered 
  entirely 
  meets 
  or 
  satisfies 
  the 
  cnditions, 
  but 
  the 
  field 
  evi- 
  

   dence 
  tends 
  to 
  cijmbine 
  these 
  and 
  suggests 
  a 
  greater 
  activity 
  in 
  

   stream 
  work 
  combined 
  with 
  a 
  longer 
  stay 
  in 
  the 
  static 
  waters 
  at 
  the 
  

   Newberry 
  level, 
  at 
  that 
  time. 
  

  

  The 
  last 
  trace 
  of 
  the 
  Newberry 
  level 
  is 
  found 
  about 
  mid-way 
  on 
  

   the 
  west 
  side 
  of 
  Lake 
  Canandaigua. 
  The 
  next 
  evidence 
  of 
  lake 
  

   action, 
  but 
  representing 
  the 
  next 
  lower 
  level, 
  is 
  found 
  to 
  the 
  north-
