  single 
  layers, 
  required 
  too 
  much 
  space, 
  and 
  it 
  therefore 
  

   became 
  necessary 
  to 
  modify 
  the 
  apparatus 
  from 
  time 
  to 
  

   time 
  so 
  that 
  larger 
  quantities 
  could 
  be 
  hatched. 
  Recently 
  

   the 
  eggs 
  of 
  the 
  shad 
  had 
  been 
  hatched 
  in 
  jars, 
  holding 
  

   from 
  2\ 
  to 
  3 
  quarts, 
  in 
  which 
  could 
  be 
  placed 
  60,000 
  or 
  

   70,000 
  eggs, 
  each 
  jar 
  being 
  about 
  two-thirds 
  full. 
  It 
  had 
  

   also 
  been 
  found 
  desirable 
  to 
  concentrate 
  the 
  work 
  of 
  the 
  

   hatcheries. 
  Formerly 
  it 
  was 
  supposed 
  that 
  these 
  must 
  be 
  

   built 
  in 
  the 
  vicinity 
  of 
  each 
  important 
  breeding-ground 
  

   of 
  the 
  fish, 
  and, 
  that 
  more 
  ground 
  might 
  be 
  covered, 
  steam 
  

   launches 
  came 
  into 
  use 
  : 
  these, 
  shortly 
  before 
  the 
  time 
  

   for 
  the 
  nets 
  to 
  be 
  hauled, 
  take 
  in 
  tow 
  a 
  number 
  of 
  

   boats, 
  and 
  proceed 
  along 
  the 
  river 
  bank, 
  leaving 
  men 
  here 
  

   and 
  there 
  at 
  the 
  various 
  fisheries. 
  After 
  the 
  eggs 
  had 
  

   been 
  secured 
  in 
  the 
  gathering 
  boats, 
  the 
  steam-launches 
  

   again 
  took 
  them 
  in 
  tow 
  on 
  its 
  way 
  to 
  the 
  hatchery. 
  This 
  

   was 
  found 
  to 
  cause 
  considerable 
  delay, 
  and 
  the 
  success 
  was 
  

   not 
  all 
  that 
  could 
  be 
  desired. 
  It 
  has 
  since 
  been 
  found 
  

   desirable 
  to 
  pack 
  the 
  eggs 
  by 
  a 
  method 
  which 
  was 
  not 
  

   formerly 
  supposed 
  possible 
  — 
  he 
  was 
  speaking 
  now 
  of 
  the 
  

   shad. 
  They 
  are 
  now 
  packed 
  in 
  trays, 
  and 
  a 
  number 
  of 
  

   trays 
  are 
  put 
  together 
  with 
  damp 
  cloths 
  between 
  them 
  ; 
  

   in 
  this 
  way 
  they 
  can 
  be 
  sent 
  by 
  a 
  steamboat 
  50, 
  75, 
  

   or 
  100 
  miles. 
  Now, 
  therefore, 
  at 
  the 
  different 
  hatching 
  

   stations, 
  men 
  were 
  sent 
  out 
  to 
  the 
  different 
  fishing 
  places 
  

   along 
  the 
  river 
  bank, 
  simply 
  provided 
  with 
  a 
  tent, 
  in 
  which 
  

   are 
  placed 
  rations 
  for 
  two 
  months, 
  a 
  few 
  spawning-pans, 
  

   dippers, 
  and 
  pails, 
  in 
  which 
  to 
  impregnate 
  the 
  eggs, 
  and 
  

   a 
  few 
  of 
  the 
  crates 
  in 
  which 
  the 
  eggs 
  were 
  shipped. 
  

   Arrangements 
  were 
  made 
  with 
  one 
  of 
  the 
  river 
  steamers 
  to 
  

   stop 
  at 
  these 
  different 
  landings 
  to 
  take 
  on 
  board 
  the 
  crates 
  

   which 
  had 
  been 
  filled 
  with 
  the 
  eggs, 
  and 
  carry 
  them 
  to 
  the 
  

   hatchery. 
  In 
  this 
  way 
  ten 
  times 
  as 
  much 
  work 
  could
