  the 
  lieader 
  and 
  cleaner, 
  for 
  the 
  next 
  washing, 
  and 
  at 
  the 
  same 
  time 
  is 
  

   scraped 
  with 
  a 
  knife 
  that 
  removes 
  the 
  scales. 
  The 
  fish 
  is 
  then 
  passed 
  

   along 
  into 
  a 
  second 
  tank 
  of 
  clear 
  water, 
  where 
  it 
  receives 
  its 
  final 
  

   washing 
  and 
  cleaning 
  and 
  is 
  made 
  ready 
  for 
  cntting 
  in 
  proper-sized 
  

   pieces. 
  A 
  series 
  of 
  semicircular 
  knife-blades 
  is 
  attached 
  to 
  a 
  roller, 
  

   the 
  blades 
  being 
  equal 
  distances 
  apart, 
  corresponding 
  with 
  the 
  size 
  

   or 
  depth 
  of 
  cans 
  to 
  be 
  filled; 
  one 
  end 
  of 
  the 
  roller 
  is 
  hinged, 
  to 
  the 
  

   other 
  end 
  a 
  handle 
  is 
  attached. 
  The 
  knives 
  are 
  raised 
  by 
  means 
  of 
  

   the 
  handle, 
  the 
  fish 
  is 
  placed 
  under 
  them, 
  and 
  with 
  one 
  quick, 
  sharp 
  

   blow 
  the 
  fish 
  is 
  entirely 
  cut 
  up 
  into 
  lengths 
  suitable 
  for 
  canning. 
  For 
  

   ] 
  pound 
  tall 
  cans, 
  7 
  knives 
  are 
  attached 
  to 
  the 
  roller; 
  for 
  1-pound 
  flat 
  

   cans, 
  13 
  knives; 
  for 
  ^-pound 
  cans, 
  17 
  knives. 
  The 
  fish 
  are 
  now 
  in 
  snit- 
  

   able 
  lengths, 
  but 
  must 
  be 
  sliced 
  into 
  sizes 
  proper 
  to 
  enter 
  the 
  cans; 
  this 
  

   is 
  quickly 
  performed, 
  and 
  the 
  pieces 
  are 
  passed 
  on 
  to 
  the 
  filling 
  gang. 
  

  

  Several 
  men 
  stand 
  at 
  one 
  or 
  both 
  sides 
  of 
  the 
  filling 
  table, 
  each 
  sup- 
  

   plied 
  with 
  small 
  s(;ales 
  adjusted 
  to 
  the 
  weight 
  of 
  the 
  cans 
  to 
  be 
  (illcd. 
  

   In 
  some 
  canneries 
  cans 
  are 
  filled 
  by 
  machinery, 
  but 
  this 
  is 
  usually 
  done 
  

   by 
  hand. 
  As 
  soon 
  as 
  filled 
  the 
  can 
  is 
  placed 
  on 
  the 
  scale; 
  if 
  it 
  shows 
  full 
  

   or 
  over 
  weight 
  it 
  is 
  passed 
  on, 
  no 
  fish 
  being 
  removed, 
  but 
  if 
  short 
  weight, 
  

   the 
  can 
  is 
  put 
  one 
  side 
  to 
  receive 
  enough 
  to 
  make 
  up 
  the 
  deficiency. 
  

  

  From 
  the 
  filler 
  the 
  can 
  passes 
  to 
  a 
  man 
  who 
  places 
  it 
  on 
  a 
  swiftly 
  

   revolving 
  plate 
  having 
  a 
  closely 
  fitting 
  cap, 
  and 
  a 
  small 
  but 
  strong 
  

   stream 
  of 
  water 
  is 
  made 
  to 
  play 
  against 
  the 
  revolving 
  can, 
  removing 
  all 
  

   grease 
  and 
  dirt. 
  A 
  small 
  scrap 
  of 
  flat 
  tin 
  is 
  put 
  on 
  top 
  of 
  its 
  contents, 
  

   and 
  the 
  prepared 
  top 
  is 
  fitted 
  on. 
  In 
  order 
  to 
  keep 
  the 
  top 
  in 
  place 
  

   pending 
  soldering, 
  the 
  can 
  next 
  goes 
  to 
  a 
  man 
  who 
  places 
  it 
  on 
  a 
  revolv- 
  

   ing 
  plate, 
  while, 
  by 
  means 
  of 
  a 
  lever 
  operated 
  with 
  his 
  foot, 
  the 
  top 
  

   piece 
  is 
  forced 
  down 
  and 
  securely 
  held 
  at 
  the 
  same 
  time 
  the 
  edges 
  are 
  

   being 
  smoothly 
  crimped. 
  The 
  sealing 
  of 
  the 
  to]) 
  is 
  ingeniously 
  accom- 
  

   plished. 
  A 
  brick 
  furnace 
  has 
  on 
  its 
  top 
  a 
  long 
  V-shajied 
  trough 
  that 
  is 
  

   kept 
  filled 
  with 
  molten 
  solder. 
  At 
  the 
  u])per 
  end 
  of 
  tlie 
  solder 
  trough 
  

   and 
  a 
  few 
  inches 
  higher 
  is 
  a 
  similar 
  one 
  filled 
  with 
  muriatic 
  acid. 
  From 
  

   the 
  crimping 
  machine 
  the 
  cans 
  drop 
  in 
  an 
  almost 
  continuous 
  stream 
  

   into 
  the 
  trough 
  with 
  acid. 
  A 
  heavy 
  endless 
  chain 
  i)asses 
  ak)ngjust 
  

   over 
  the 
  troughs, 
  and 
  by 
  the 
  friction 
  from 
  the 
  chain 
  the 
  cans 
  are 
  

   carried 
  on 
  first 
  through 
  the 
  acid, 
  which 
  touches 
  only 
  the 
  outer 
  edge 
  ot 
  

   the 
  top 
  of 
  the 
  can 
  and 
  prepares 
  it 
  to 
  receive 
  the 
  solder 
  through 
  which 
  

   it 
  next 
  passes. 
  The 
  top 
  of 
  each 
  can 
  has 
  a 
  small 
  hole 
  punched 
  in 
  it 
  to 
  

   ])ermit 
  the 
  escape 
  of 
  air 
  as 
  the 
  can 
  becomes 
  heated 
  in 
  its 
  ]»assage 
  

   through 
  the 
  trough 
  of 
  molten 
  solder. 
  Here 
  may 
  be 
  noticed 
  the 
  utility 
  of 
  

   the 
  small 
  piece 
  of 
  tin 
  before 
  mentioned 
  as 
  being 
  put 
  in 
  the 
  can, 
  with- 
  

   out 
  which 
  the 
  hole 
  is 
  liable 
  to 
  be 
  clogged 
  u]) 
  with 
  fish, 
  and, 
  tlie 
  vent 
  

   being 
  closed, 
  the 
  cans 
  are 
  liable 
  to 
  be 
  badly 
  strained, 
  made 
  leaky, 
  and 
  

   have 
  the 
  entire 
  top 
  blown 
  out. 
  

  

  The 
  endless 
  chain, 
  having 
  rolled 
  the 
  cans 
  through 
  Ihe 
  solder, 
  drops 
  

   them 
  on 
  an 
  inclined 
  plane 
  some 
  30 
  or 
  40 
  feet 
  in 
  length. 
  Shortly 
  before 
  

   reaching 
  the 
  bottom 
  of 
  this 
  incline 
  the 
  cans 
  are 
  met 
  with 
  a 
  shower 
  bath
