  the 
  season, 
  I 
  am 
  quite 
  confi- 
  

   dent 
  that 
  the 
  total 
  result 
  above 
  given 
  would 
  have 
  been 
  

   increased 
  to 
  over 
  :30,000,000. 
  But 
  when 
  the 
  records 
  of 
  

   the 
  hatching 
  operations 
  on 
  the 
  Potomac 
  River 
  for 
  1880 
  

   are 
  compared 
  with 
  those 
  of 
  other 
  years, 
  as 
  given 
  in 
  pre- 
  

   vious 
  reports, 
  it 
  will 
  be 
  seen 
  that 
  the 
  organization 
  of 
  the 
  

   work 
  on 
  such 
  a 
  scale 
  w(mld 
  have 
  ap]>eai'ed 
  wholly 
  un- 
  

   necessary. 
  

  

  The 
  Steamer 
  ''Lookout'" 
  continued 
  her 
  nightly 
  trips 
  

   down 
  the 
  river 
  with 
  vai-ying 
  success 
  until 
  the 
  end 
  of 
  

   June. 
  

  

  As 
  the 
  law 
  j)i'ohibiting 
  the 
  catcliing 
  of 
  hsh 
  after 
  the 
  

   1st 
  of 
  June 
  is 
  utteily 
  ignoied 
  on 
  the 
  Potomac, 
  outside 
  of 
  

   the 
  District 
  of 
  Columbia, 
  I 
  determined 
  to 
  gather 
  all 
  the 
  

   spawn 
  that 
  could 
  be 
  obtained 
  from 
  the 
  fish 
  taken, 
  and 
  

   from 
  them 
  producing 
  as 
  many 
  young 
  fish 
  as 
  possible 
  in 
  

   order 
  to 
  keep 
  u]j 
  the 
  future 
  supply 
  in 
  this 
  river. 
  The 
  

   expei'iences 
  of 
  this 
  year 
  on 
  the 
  Potomac 
  are 
  most 
  impor- 
  

   tant, 
  not 
  only 
  on 
  account 
  of 
  the 
  magnitude 
  of 
  the 
  work 
  

   and 
  of 
  the 
  results 
  accomplished, 
  but 
  as 
  affording 
  a 
  clear 
  

   indication 
  of 
  the 
  good 
  results 
  of 
  oui- 
  former 
  effoits 
  and 
  

   as 
  demonstrating 
  how 
  readily 
  and 
  successfully 
  the 
  work
