  effect 
  which 
  the 
  salt 
  might 
  have 
  upon 
  the 
  Smelt 
  spawn, 
  a 
  trial 
  

   could 
  he 
  very 
  easily 
  made 
  of 
  one 
  of 
  the 
  jars 
  only, 
  and 
  the 
  

   result 
  noted, 
  i. 
  e., 
  as 
  to 
  whether 
  there 
  were 
  any 
  more 
  dead 
  

   eggs 
  in 
  the 
  jar 
  after 
  the 
  salt 
  hath 
  than 
  before. 
  The 
  salt 
  

   bath 
  is 
  very 
  effectual, 
  and 
  perfectly 
  innocuous 
  with 
  Trout 
  

   eggs 
  and 
  aquaria, 
  and 
  there 
  is 
  no 
  reason 
  to 
  suppose 
  it 
  would 
  

   be 
  otherwise 
  with 
  the 
  eggs 
  of 
  the 
  Smelt. 
  With 
  the 
  growth 
  

   and 
  extension 
  of 
  fungi 
  in 
  the 
  jars 
  thus 
  prevented, 
  and 
  with 
  

   that 
  care 
  in 
  the 
  manipuLition 
  of 
  the 
  spawn 
  which 
  I 
  have 
  

   suggested, 
  the 
  Commission 
  ought, 
  with 
  the 
  experience 
  of 
  

   the 
  present 
  season, 
  to 
  be 
  able 
  to 
  work 
  a=i 
  successfully 
  here- 
  

   after 
  with 
  Smelt 
  spawn 
  as 
  they 
  have 
  shown 
  themselves 
  to 
  be 
  

   with 
  spawn 
  which 
  is 
  non-adhesive, 
  such 
  as 
  that 
  of 
  the 
  Trout 
  

   and 
  Shad. 
  

  

  The 
  work 
  of 
  the 
  Commission, 
  from 
  nececsity, 
  as 
  well 
  as 
  

   inclination, 
  is 
  to 
  increase 
  the 
  food 
  supply 
  as 
  profitably 
  to 
  the 
  

   State 
  as 
  possible, 
  and 
  while 
  the 
  matter 
  of 
  profitable 
  propa- 
  

   gation 
  rests 
  to 
  a 
  great 
  extent 
  in 
  the 
  hands 
  of 
  the 
  Commis- 
  

   sion, 
  through 
  the 
  experience 
  which 
  is 
  gained 
  each 
  year, 
  

   yet 
  other 
  circumstances 
  enter 
  largely 
  into 
  these 
  calculations, 
  

   such, 
  for 
  instance, 
  as 
  their 
  ability 
  to 
  do 
  as 
  they 
  would 
  like, 
  

   and 
  to 
  work 
  just 
  at 
  the 
  time 
  they 
  desire. 
  If 
  in 
  the 
  propa- 
  

   gation 
  of 
  the 
  Smelt 
  the 
  Commission 
  could 
  so 
  arrange 
  their 
  

   time 
  for 
  work 
  upon 
  the 
  Raritan 
  as 
  to 
  be 
  there 
  when 
  the 
  tem- 
  

   perature 
  of 
  the 
  water 
  used 
  in 
  tlie 
  hatching 
  jars 
  is 
  from 
  42° 
  

   to 
  44° 
  at 
  an 
  average, 
  they 
  would 
  undoubtedly 
  meet 
  with 
  the 
  

   greatest 
  and 
  best 
  success, 
  especially 
  in 
  a 
  pecuniary 
  point 
  of 
  

   view, 
  since 
  at 
  such 
  a 
  temperature 
  the 
  young 
  fish 
  could 
  be 
  

   hatched 
  out 
  in 
  about 
  tliree 
  weeks. 
  

  

  The 
  most 
  serious 
  objection 
  to 
  this 
  plan 
  is 
  in 
  the 
  running 
  

   of 
  the 
  fish 
  themselves, 
  the 
  greater 
  portion 
  of 
  the 
  fish 
  passing 
  

   into 
  the 
  river 
  earlier 
  in 
  the 
  season. 
  But 
  if 
  the 
  method 
  is 
  

   adopted 
  of 
  keeping 
  the 
  males 
  and 
  females 
  in 
  confinement 
  

   until 
  ripe, 
  even 
  this 
  objection 
  might 
  have 
  very 
  little 
  weight, 
  

   and 
  the 
  spawn 
  might 
  be 
  handled 
  at 
  a 
  time 
  when 
  it 
  could 
  be 
  

   so 
  done 
  most 
  expeditiou.sly 
  and 
  ijrofitably.
