  mission, 
  not 
  only 
  on 
  

   account 
  of 
  tlie 
  success 
  attained 
  in 
  the 
  attenijtted 
  propa- 
  

   gation 
  of 
  several 
  varieties 
  of 
  valuable 
  tisli 
  by 
  artificial 
  

   means, 
  but 
  because 
  of 
  the 
  accumulated 
  proofs 
  which 
  

   have 
  been 
  afforded 
  of 
  the 
  success 
  of 
  the 
  efi'oi-t 
  to 
  fully 
  

   restock 
  the 
  waters 
  of 
  the 
  State 
  with

  In 
  my 
  Report 
  of 
  January, 
  1880, 
  relating 
  to 
  the 
  opera- 
  

   tions 
  of 
  the 
  Commission 
  during 
  the 
  year 
  1870, 
  it 
  was 
  

   shown 
  that 
  there 
  had 
  been 
  a 
  very 
  marked 
  increase 
  of 
  

   shad 
  foi' 
  that 
  year 
  at 
  those 
  points 
  near 
  the 
  head 
  of 
  the 
  

   Chesapeake 
  Bay 
  and 
  in 
  the 
  Potomac 
  River, 
  where 
  com- 
  

   plete 
  records 
  had 
  been 
  kept. 
  During 
  tlie 
  Spring 
  of 
  

   1880, 
  this 
  increase 
  was 
  even 
  more 
  decided, 
  as 
  the 
  catch 
  

   for 
  that 
  season 
  not 
  only 
  exceeded, 
  very 
  largely, 
  the 
  

   returns 
  for 
  any 
  one 
  of 
  several 
  previous 
  years 
  ; 
  Init 
  also, 
  

   and 
  in 
  a 
  very 
  mai'ked 
  degree, 
  the 
  catch 
  for 
  J 
  870 
  — 
  the 
  

   year 
  immediately 
  preceding. 
  

  

  The 
  following 
  figures,

  Col. 
  Marshall 
  

   McDonald, 
  from 
  returns 
  secured

  the 
  various 
  

   sources 
  of 
  information 
  made 
  available 
  by 
  the 
  investiga- 
  

   tions 
  of 
  the 
  Census 
  Bureau 
  for 
  the 
  Census 
  (^f

  show- 
  

   most 
  clearly 
  the 
  efl'ect 
  which 
  the 
  operations 
  at 
  the 
  head 
  

   of 
  the 
  Bay, 
  and 
  tlie 
  large 
  deposit 
  of 
  young 
  shad

   Potomac

  liave 
  had 
  upon 
  the 
  yield 
  of 
  those
