  This 
  consisted 
  of 
  six 
  Ferguson 
  hatching-jars, 
  

  

  attached 
  by 
  rubber 
  tubes 
  and 
  stop-cocks 
  to 
  a 
  central 
  tub 
  

   or 
  reservoir, 
  which 
  Avas 
  supplied 
  with 
  water 
  from 
  the 
  city 
  

   hydrant. 
  This 
  reservoir 
  had 
  a 
  waste-pipe 
  passing 
  down 
  its 
  

   centre^ 
  so 
  that 
  the 
  flow 
  of 
  water 
  upon 
  the 
  jars 
  could 
  be 
  regu- 
  

   lated 
  as 
  completely 
  as 
  could 
  be 
  desired. 
  The 
  remaining 
  

   apparatus 
  consisted 
  of 
  trays, 
  pans, 
  pails, 
  dippers, 
  &c. 
  for 
  

   the 
  purpose 
  of 
  manipulating 
  the 
  spawn. 
  The 
  methods 
  era- 
  

   ployed 
  by 
  the 
  Commission 
  for 
  the 
  propagation 
  of 
  the 
  young 
  

   Smelt, 
  were 
  crude 
  and 
  imperfect, 
  to 
  the 
  extent 
  that 
  they 
  

   were 
  trial 
  methods, 
  and 
  that 
  the 
  accommodations 
  were 
  not 
  

   such 
  as 
  were 
  desired, 
  but 
  sucli 
  only 
  as 
  could 
  be 
  obtained 
  

   upon 
  the 
  spur 
  of 
  the 
  moment, 
  just 
  when 
  it 
  was 
  necessary 
  to 
  

   handle 
  and 
  care 
  for 
  the 
  spawn. 
  

  

  The 
  Commission 
  had 
  a 
  somewhat 
  difficult 
  work 
  before 
  it, 
  

   which 
  was 
  the 
  handling, 
  not 
  only 
  of 
  a 
  species 
  of 
  spawn 
  which 
  

   had 
  never 
  been 
  successfully 
  handled 
  before, 
  but 
  of 
  a 
  species 
  

   of 
  adhesive 
  spawn, 
  and 
  at 
  the 
  same 
  time, 
  if 
  possible, 
  to 
  bring 
  

   out 
  a 
  profitable 
  result 
  in 
  the 
  number 
  of 
  young 
  fish 
  hatched. 
  

   Such 
  work 
  must 
  always 
  be 
  more 
  or 
  less 
  experimental 
  ; 
  if 
  the 
  

   experiments 
  happen, 
  to 
  be 
  all 
  right, 
  the 
  result 
  will 
  be 
  very 
  

   favorable 
  in 
  a 
  fine 
  lot 
  of 
  young 
  fish 
  ; 
  but 
  if 
  the 
  experiments 
  

   are 
  not 
  all 
  right, 
  the 
  result 
  may 
  be 
  the 
  entire 
  loss 
  of 
  spawn, 
  

   time, 
  patience 
  and 
  money, 
  and 
  the 
  latter 
  is 
  a 
  very 
  important 
  

   item 
  in 
  conducting 
  experimenti 
  in 
  fish-culture.
