  ed 
  for, 
  however, 
  when 
  we 
  consider 
  that 
  the 
  Carp 
  not 
  

   only 
  tind 
  in 
  our 
  waters 
  the 
  greatfest 
  abundance 
  of 
  

   natural 
  food, 
  but 
  that 
  the 
  comparative 
  mildness 
  of 
  our 
  

   climate 
  permits 
  them 
  to 
  feed 
  through 
  a 
  inuch 
  more 
  ex- 
  

   tended 
  ]iorti()n 
  of 
  each 
  year 
  than 
  is 
  possible 
  in 
  

   Northern 
  Europe, 
  where 
  long 
  and 
  rigorous 
  winters 
  

   condemn 
  them 
  to 
  extended 
  periods 
  of 
  hibernation. 
  

  

  The 
  fact 
  of 
  such 
  relative 
  rapidity 
  of 
  growth 
  has 
  at 
  

   least 
  been 
  clearly 
  established, 
  and 
  affords 
  a 
  new^ 
  evidence 
  

   — 
  as 
  gratifying 
  as 
  it 
  was 
  unexpected 
  — 
  of 
  the 
  complete 
  

   success 
  which 
  has 
  rewarded 
  the 
  efforts 
  of 
  Prof. 
  Baird 
  to 
  

   introduce 
  this 
  valuable 
  fish 
  into 
  American 
  w^aters. 
  

  

  Reverting 
  to 
  our 
  narrative 
  of 
  oi:)erations 
  for 
  the 
  year 
  

   1879, 
  the 
  ponds 
  in 
  Druid 
  Hill 
  Park 
  were 
  drawn 
  early 
  in 
  

   May, 
  all 
  eels, 
  frogs 
  and 
  fish 
  inimical 
  to 
  the 
  Carp 
  found 
  

   in 
  them 
  were 
  destroyed, 
  and 
  a 
  number 
  of 
  aquatic 
  plants 
  

   were 
  set 
  out 
  to 
  serve 
  as 
  food 
  for 
  the 
  fish 
  and 
  as 
  recepta- 
  

   cles 
  for 
  their 
  eggs. 
  

  

  On 
  the 
  7th 
  of 
  the 
  same 
  month 
  the 
  breeding 
  fish 
  wm-e 
  

   placed 
  in 
  ponds 
  Nos. 
  3 
  and 
  4 
  — 
  thirty-one 
  Leather 
  Carp 
  

   being 
  deposited 
  in 
  the 
  former, 
  and 
  one 
  hundred 
  and 
  

   three 
  in 
  the 
  latter. 
  A 
  few 
  Mirror 
  Carp 
  of 
  varying 
  sizes 
  

   were 
  also 
  placed 
  in 
  pond 
  No. 
  4, 
  and 
  a 
  few 
  young 
  Carp 
  

   in 
  pond 
  No. 
  1 
  — 
  our 
  main 
  dependence 
  being, 
  of 
  coiirse, 
  

   the 
  adult 
  lish 
  in 
  ponds 
  Nos. 
  3 
  and 
  4. 
  The 
  imported 
  

   Golden 
  Ides 
  were 
  still 
  kept 
  in 
  pond 
  No. 
  2. 
  

  

  Immediately 
  after 
  being 
  returned 
  to 
  the 
  ponds 
  the 
  

   fish 
  commenced 
  to 
  spawn, 
  and 
  it 
  is 
  quite 
  likely 
  that 
  the 
  

   drawing 
  of 
  the 
  water, 
  and 
  disturbance 
  of 
  tlie 
  lish 
  so 
  near 
  

   their 
  spawning 
  time, 
  was 
  so 
  far 
  detrimental 
  to 
  them 
  that 
  

   the 
  yield 
  for 
  tliis 
  year 
  was 
  somewhat 
  decreased 
  in 
  

   consequence. 
  A 
  number 
  of 
  twigs 
  and 
  l)lades 
  of 
  water 
  

   grasses 
  on 
  which 
  the 
  lish 
  had 
  deposited 
  their 
  

   eggs 
  w^ere 
  taken 
  from 
  the 
  large 
  x>onds, 
  wath 
  the 
  eggs 
  

   attached, 
  and 
  were 
  placed 
  in 
  the 
  brick 
  ponds 
  adjacent 
  to 
  

   No. 
  2, 
  which 
  had 
  been 
  especially 
  prepared 
  with 
  a 
  view 
  

   to 
  the 
  purposes 
  of 
  artificial 
  breeding. 
  In 
  a 
  few 
  days 
  the
