  The 
  period 
  in 
  which 
  Shad-hatching 
  operations 
  can 
  he 
  suc- 
  

   cessfully 
  carried 
  on 
  in 
  Maryland 
  waters, 
  is 
  limited 
  by 
  the 
  

   conditions 
  and 
  temperature 
  of 
  the 
  water, 
  to 
  about 
  six 
  weeks^ 
  

   extending 
  from 
  the 
  last 
  week 
  in 
  April, 
  the 
  time 
  when 
  the 
  

   first 
  ripe 
  fish 
  are 
  found, 
  until 
  the 
  10th 
  of 
  June, 
  when 
  tlie 
  

   catching 
  of 
  Shad 
  is 
  prohibited 
  by 
  law, 
  and 
  fishing 
  ceases. 
  

   The 
  necessity 
  for 
  extending 
  the 
  period 
  in 
  Avhich 
  the 
  gather- 
  

   ing 
  of 
  spawn, 
  and 
  the 
  development 
  of 
  the 
  same, 
  can 
  be 
  con- 
  

   ducted, 
  caused 
  me 
  to 
  investigate 
  the 
  state 
  and 
  conditions 
  of 
  

   the 
  fisheries 
  further 
  south, 
  believing 
  that 
  by 
  taking 
  advan- 
  

   tage 
  of 
  the 
  earlier 
  run 
  of 
  fish 
  into 
  the 
  rivers 
  more 
  southern 
  

   than 
  those 
  flowing 
  into 
  the 
  Chesapeake 
  bay, 
  active 
  operations 
  

   in 
  the 
  field 
  could 
  be 
  commenced 
  some 
  five 
  or 
  six 
  weeks 
  

   earlier, 
  and 
  a 
  very 
  much 
  larger 
  number 
  of 
  young 
  fish 
  pro- 
  

   cured 
  for 
  stocking 
  the 
  streams 
  of 
  the 
  State. 
  

  

  With 
  tliis 
  view, 
  I 
  communicated 
  with 
  the 
  Commissioners 
  

   of 
  North 
  Carolina 
  and 
  Virginia, 
  and 
  they 
  expressed 
  their 
  

   willingness 
  and 
  desire 
  to 
  co-operate 
  in 
  the 
  work 
  at 
  points 
  

   within 
  their 
  States. 
  Having 
  been 
  informed 
  by 
  Dr. 
  Wm. 
  11. 
  

   Capehart, 
  the 
  owner 
  and 
  operator 
  of 
  two 
  extensive 
  fislieries 
  

   on 
  the 
  Albemarle 
  sound, 
  that 
  spawning 
  fish 
  could 
  be 
  had 
  in 
  

   large 
  numbers 
  in 
  the 
  neighborhood 
  of 
  his 
  fisheries 
  during 
  

   the 
  fishing 
  season, 
  which 
  commences 
  about 
  the 
  1st 
  of 
  ]\rarcli 
  

   — 
  as 
  Dr. 
  Capehart's 
  intelligent 
  observations 
  c^nkl 
  bo 
  relied 
  

   on 
  — 
  I 
  deemed 
  it 
  of 
  sufficient 
  importance 
  to 
  the 
  future 
  of 
  our
