  The 
  wiudowed 
  bucket 
  is 
  put 
  iu 
  a 
  trough 
  under 
  a 
  small 
  jet 
  of 
  water, 
  

   conducted 
  by 
  a 
  rubber 
  tube 
  to 
  the 
  bottom 
  of 
  the 
  bucket. 
  The 
  jet 
  

   discharging 
  at 
  the 
  bottom 
  of 
  the 
  bucket, 
  and 
  the 
  surplus 
  water 
  escaping 
  

   through 
  the 
  perforated 
  window, 
  assist 
  in 
  the 
  process 
  of 
  tempering. 
  

   The 
  temperature 
  being 
  equalized, 
  the 
  fish 
  are 
  carefully 
  ladled 
  into 
  

   troughs 
  or. 
  pools 
  and 
  the 
  various 
  sizes 
  sorted 
  and 
  separated 
  into 
  difiereut 
  

   troughs. 
  

  

  A 
  part 
  of 
  the 
  fry 
  do 
  not 
  find 
  their 
  way 
  through 
  the 
  wire 
  screens 
  into 
  

   the 
  cut-off, 
  and 
  all 
  around 
  the 
  margin 
  of 
  the 
  pond, 
  even 
  in 
  the 
  deep 
  

   water, 
  straggling 
  fry 
  may 
  be 
  seen. 
  Sometimes 
  these 
  scattered 
  youngsters 
  

   will 
  be 
  small, 
  but 
  generally 
  they 
  are 
  the 
  largest. 
  After 
  all 
  the 
  fry 
  have 
  

   been 
  captured 
  from 
  the 
  cut-off" 
  and 
  the 
  season's 
  spawning 
  is 
  over, 
  the 
  

   pond 
  is 
  drawn 
  to 
  collect 
  and 
  save 
  those 
  that 
  have 
  failed 
  to 
  come 
  into 
  

   the 
  cut-off". 
  This 
  work 
  is 
  generally 
  in 
  June 
  or 
  July, 
  when 
  the 
  ponds 
  

   are 
  quite 
  warm 
  and 
  the 
  temperature 
  of 
  the 
  atmosphere 
  is 
  high, 
  and 
  is 
  

   carried 
  out 
  with 
  extreme 
  watchfulness 
  and 
  care, 
  as 
  the 
  midsummer 
  

   drawing 
  of 
  a 
  bass 
  pond 
  is 
  the 
  most 
  delicate 
  operation 
  connected 
  with 
  

   their 
  propagation 
  in 
  ponds. 
  These 
  fry 
  need 
  to 
  be 
  "tempered" 
  and 
  

   sorted 
  in 
  the 
  same 
  way 
  as 
  advised 
  for 
  other 
  fry. 
  

  

  During 
  the 
  various 
  stages 
  of 
  its 
  life 
  the 
  bass 
  is 
  subject 
  to 
  the 
  attack 
  

   of 
  enemies 
  of 
  many 
  kinds. 
  The 
  fish-eating 
  birds, 
  like 
  the 
  kingfisher; 
  

   wading 
  birds, 
  like 
  the 
  heron, 
  and 
  amphibious 
  animals, 
  like 
  the 
  mink 
  

   and 
  muskrat, 
  must 
  be 
  guarded 
  against. 
  Snakes, 
  frogs, 
  turtles, 
  and 
  

   various 
  beetles 
  are 
  dangerous 
  to 
  the 
  fry, 
  and 
  sometimes 
  even 
  to 
  adult 
  

   fish. 
  

  

  SHIPPING 
  FRY. 
  

  

  Collecting 
  for 
  shipment 
  occurs 
  in 
  the 
  cool 
  days 
  of 
  autumn, 
  as 
  experi- 
  

   ence 
  has 
  shown 
  that 
  the 
  bass 
  can 
  be 
  much 
  better 
  and. 
  more 
  safely 
  

   transported 
  in 
  the 
  spring 
  and 
  fall 
  than 
  in 
  the 
  summer. 
  They 
  can 
  be 
  

   transported 
  more 
  cheaply 
  iu 
  midwinter 
  than 
  any 
  other 
  time, 
  but 
  when 
  

   fish 
  are 
  moved 
  long 
  distances 
  in 
  very 
  cold 
  weather 
  (or 
  at 
  any 
  other 
  time 
  

   when 
  much 
  ice 
  is 
  used 
  in 
  the 
  cans) 
  many 
  die 
  from 
  gill 
  troubles. 
  After 
  

   the 
  ponds 
  are 
  freed 
  from 
  vegetation 
  and 
  are 
  ready 
  for 
  drawing 
  off, 
  

   the 
  water 
  level 
  is 
  reduced 
  slowly. 
  Every 
  precaution 
  is 
  taken 
  not 
  to 
  

   frighten 
  the 
  fish, 
  and 
  with 
  this 
  in 
  view 
  no 
  more 
  attendants 
  are 
  allowed 
  

   about 
  the 
  bank 
  than 
  are 
  absolutely 
  necessary. 
  Black 
  bass 
  when 
  

   frightened 
  will 
  burrow 
  in 
  the 
  mud 
  and 
  live 
  there 
  an 
  incredible 
  length 
  

   of 
  time, 
  and 
  if 
  a 
  fingerling 
  burrow 
  in 
  the 
  mud 
  when 
  the 
  pond 
  is 
  being 
  

   drawn 
  he 
  may 
  prove 
  a 
  dangerous 
  occupant 
  the 
  following 
  spring 
  when 
  

   the 
  young 
  fry 
  are 
  introduced. 
  The 
  same 
  precautious 
  should 
  be 
  observed 
  

   in 
  transferring 
  fingerlings 
  as 
  with 
  the 
  very 
  young 
  fry.
