﻿in 
  a 
  few 
  days 
  and 
  the 
  young 
  grow 
  very 
  rapidly. 
  They 
  feed 
  

   voraciously 
  upon 
  so-called 
  frog-spittle, 
  the 
  green 
  alga 
  scum 
  

   that 
  is 
  so 
  common 
  in 
  frog 
  ponds. 
  Consequently 
  such 
  waters 
  

   are 
  especially 
  adapted 
  for 
  carp. 
  Whenever 
  the 
  water 
  becomes 
  

   chilled 
  down 
  to 
  perhaps 
  40°, 
  and 
  especially 
  when 
  frozen 
  over 
  

   at 
  the 
  top, 
  the 
  fish 
  bury 
  themselves 
  in 
  the 
  mud, 
  aggregating 
  in 
  

   lots 
  from 
  fifty 
  to 
  one 
  hundred, 
  frequently 
  with 
  their 
  tails 
  pro- 
  

   jecting 
  and 
  constituting 
  what 
  is 
  called 
  in 
  Germany 
  kettles 
  or 
  

   rolls. 
  It 
  is 
  very 
  important 
  that 
  they 
  should 
  not 
  be 
  disturbed 
  

   under 
  such 
  circumstances. 
  Of 
  course 
  while 
  hybenating 
  

   in 
  this 
  way 
  they 
  are 
  not 
  feeding, 
  although 
  they 
  are 
  said 
  not 
  

   to 
  lose 
  appreciably 
  in 
  weight. 
  In 
  the 
  more 
  southern 
  regions, 
  

   where 
  the 
  waters 
  do 
  not 
  freeze, 
  they 
  will 
  probably 
  feed 
  

   throughout 
  the 
  year 
  and 
  make 
  a 
  more 
  rapid 
  growth. 
  So 
  far, 
  

   no 
  waters 
  have 
  proved 
  too 
  warm 
  for 
  them. 
  As 
  regards 
  the 
  

   best 
  plants 
  for 
  a 
  carp 
  pond, 
  I 
  may 
  mention 
  the 
  ordinary 
  pond- 
  

   weeds 
  j)ontederia 
  and 
  sagittaria 
  — 
  splatter 
  docks 
  or 
  pond 
  

   lilies 
  ; 
  and, 
  indeed, 
  any 
  of 
  the 
  kinds 
  that 
  grow 
  in 
  the 
  water 
  

   with 
  leaves 
  floating 
  upon 
  the 
  surface, 
  duck-weed 
  among 
  the 
  

   number. 
  Those 
  which 
  produce 
  seeds, 
  like 
  the 
  wild 
  rice, 
  are 
  

   especially 
  desirable, 
  as 
  the 
  fish 
  feed 
  voraciously 
  upon 
  them.

  truly 
  yours,

  Dr. 
  Hessel, 
  superintendent 
  of 
  the 
  ponds 
  at 
  Washington, 
  

   makes 
  the 
  following 
  statement, 
  which 
  shows 
  how 
  well 
  adapted 
  

   this 
  fish 
  is 
  to 
  fill 
  a 
  need 
  so 
  long 
  felt 
  by 
  those 
  having 
  waters 
  too 
  

   warm 
  and 
  limited 
  for 
  the 
  propagation 
  of 
  brook 
  trout 
  and 
  

   other 
  game 
  fishes 
  : 
  

  

  " 
  ' 
  The 
  carp 
  is 
  able,' 
  says 
  Dr. 
  Hessel, 
  ' 
  to 
  live 
  in 
  water 
  where 
  

   other 
  fishes 
  could 
  not 
  possibly 
  exist 
  — 
  for 
  instance, 
  in 
  the 
  pools 
  

   of 
  bog-meadows 
  or 
  sloughs.' 
  Though 
  it 
  is 
  not 
  to 
  be 
  inferred 
  

   from 
  this 
  that 
  the 
  best 
  carp 
  ponds 
  should 
  be 
  thus 
  located. 
  

  

  "In 
  Silesia, 
  puddles 
  two 
  or 
  three 
  feet 
  deep, 
  in 
  the 
  villages, 
  

   are 
  used 
  for 
  raising 
  two 
  year 
  old 
  car^D 
  for 
  stocking 
  distant 
  

   waters. 
  From 
  this 
  resource 
  a 
  single 
  estate 
  realized 
  what 
  

   would 
  amount 
  to 
  about 
  fifty-five 
  dollars 
  to 
  the 
  acre 
  of 
  pond
