  fall 
  with 
  the 
  water 
  in 
  the 
  river. 
  In 
  this 
  manner 
  we 
  thor- 
  

   oughly 
  guarded 
  against 
  any 
  disaster 
  from 
  freshets 
  or 
  a 
  sudden 
  

   fall 
  of 
  the 
  river. 
  An 
  examination 
  of 
  the 
  accompanying 
  tabic 
  

   will 
  show 
  how 
  successful 
  the 
  experiment 
  was, 
  and 
  how 
  small 
  

   the 
  daily 
  losses 
  of 
  eggs. 
  The 
  experiment 
  demonstrated 
  how 
  

   practical 
  it 
  is 
  to 
  hatch 
  the 
  eggs 
  and 
  care 
  for 
  the 
  fish 
  until 
  the 
  

   sac 
  is 
  absorbed 
  without 
  the 
  expensive 
  adjunct 
  of 
  an 
  elaborate 
  

   hatching-house. 
  With 
  the 
  experiences 
  of 
  this 
  season 
  we 
  are 
  

   convinced 
  that 
  the 
  most 
  effectual 
  means 
  of 
  stocking 
  streams, 
  

   with 
  fish 
  not 
  easily 
  accessible 
  by 
  rail 
  and 
  wagon, 
  is 
  to 
  pursue 
  

   methods 
  similar 
  to 
  those 
  above 
  described. 
  It 
  is 
  entirely 
  prac- 
  

   ticable 
  with 
  an 
  equipment 
  which 
  can 
  readily 
  be 
  carried 
  in 
  a 
  

   wagon 
  to 
  organize 
  a 
  hatching-station 
  where 
  puro 
  and 
  whole- 
  

   some 
  water 
  can 
  be 
  found, 
  almost 
  as 
  quickly 
  as 
  a 
  tent 
  can 
  be 
  

   pitched, 
  and 
  that, 
  too, 
  on 
  a 
  scale 
  sufficient 
  to 
  provide 
  for 
  a 
  

   half 
  million 
  trout 
  eggs. 
  It 
  will 
  be 
  observed 
  that 
  those 
  fish 
  

   kept 
  in 
  the 
  warmer 
  waters 
  of 
  Druid 
  Hill 
  Park 
  were 
  hatched 
  

   and 
  ready 
  for 
  distribution 
  by 
  the 
  twenty-sixth 
  of 
  Xovember, 
  

   about 
  the 
  time 
  the 
  eggs 
  which 
  were 
  hatching 
  in 
  the 
  upper 
  

   waters 
  of 
  the 
  Potomac 
  were 
  freed 
  from 
  the 
  shell, 
  showing 
  a 
  

   retardation 
  of 
  about 
  one 
  month 
  by 
  the 
  employment 
  of 
  the 
  

   cold 
  mountain 
  water. 
  When 
  the 
  development 
  proceeds 
  slowly, 
  

   the 
  young 
  fish 
  are 
  more 
  vigorous 
  than 
  those 
  from 
  rapidly 
  

   hatched 
  eggs. 
  These 
  experiments 
  would 
  indicate 
  that 
  better 
  

   results 
  would 
  hereafter 
  be 
  obtained 
  by 
  seeking 
  those 
  localities 
  

   with 
  colder 
  water. 
  All 
  of 
  the 
  fish 
  obtained 
  from 
  the 
  200,000 
  

   eggs 
  transferred 
  to 
  the 
  hatching-station 
  in 
  the 
  north 
  branch 
  

   of 
  the 
  Potomac 
  were 
  turned 
  loose 
  in 
  the 
  river. 
  The 
  details 
  

   of 
  the 
  distribution 
  obtained 
  from 
  300,000 
  eggs 
  retained 
  at 
  the 
  

   Druid 
  Hill 
  Hatching-House 
  will 
  be 
  found 
  in 
  the 
  accompany- 
  

   ing 
  table.
