  barn 
  20 
  by 
  20 
  feet 
  square 
  four 
  rows 
  of 
  fires 
  are 
  built, 
  four 
  

   fires 
  in 
  a 
  row, 
  1^ 
  bushels 
  to 
  the 
  sixteen 
  fires. 
  Tlie 
  entire 
  

   process 
  requires 
  from 
  three 
  to 
  four 
  entire 
  clays. 
  About 
  100 
  

   bushels 
  of 
  charcoal, 
  at 
  4 
  cents 
  per. 
  bushel, 
  are 
  allowed 
  to 
  800 
  

   pounds 
  of 
  tobacco. 
  

  

  FLUE- 
  CURING. 
  

  

  Since 
  curing 
  by 
  flues 
  promises 
  very 
  soon 
  to 
  supersede 
  all 
  

   other 
  methods, 
  this 
  process 
  is 
  more 
  particularly 
  described. 
  

   The 
  only 
  difference 
  between 
  that 
  and 
  charcoal-curing 
  is 
  in 
  

   the 
  manner 
  of 
  applying 
  heat. 
  Two 
  distinct 
  stages 
  are 
  re- 
  

   cognized 
  in 
  curing: 
  yellowing 
  with 
  a 
  damp 
  heat 
  at 
  a 
  low 
  

   temperature, 
  which 
  is 
  generally 
  90°, 
  or, 
  when 
  the 
  tobacco 
  is 
  

   very 
  light 
  and 
  yellow, 
  100°; 
  but 
  if 
  the 
  weather 
  is 
  very 
  cool, 
  

   80°. 
  The 
  second 
  is 
  the 
  drying, 
  which 
  may 
  be 
  divided 
  into 
  

   curing 
  the 
  leaf 
  and 
  curing 
  the 
  stalk. 
  

  

  Yellowing. 
  — 
  This 
  is 
  done 
  at 
  90°, 
  or 
  at 
  80° 
  if 
  the 
  weather 
  

   be 
  cool, 
  in 
  from 
  eighteen 
  to 
  thirty-six 
  hours, 
  until 
  the 
  desired 
  

   color 
  is 
  attained. 
  

  

  Drying 
  or 
  curing 
  is 
  then 
  effected 
  by 
  the 
  following 
  man- 
  

   agement 
  of 
  temperature 
  : 
  95° 
  for 
  two 
  hours, 
  100° 
  for 
  two 
  

   hours, 
  105° 
  for 
  two 
  hours, 
  110° 
  for 
  two 
  hours, 
  115° 
  for 
  two 
  

   hours, 
  120° 
  for 
  six 
  hours, 
  130° 
  for 
  two 
  hours, 
  140° 
  for 
  two 
  

   hours, 
  150° 
  for 
  two 
  hours, 
  and 
  160° 
  for 
  twenty-four 
  hours, 
  

   the 
  last 
  temperature 
  being 
  kept 
  up 
  until 
  the 
  stalks 
  and 
  

   stems 
  are 
  dried. 
  This 
  table 
  is 
  for 
  tobacco 
  not 
  gross 
  and 
  

   very 
  yellow 
  when 
  cut, 
  and 
  to 
  be 
  modified 
  with 
  judgment. 
  

   If 
  the 
  tobacco 
  is 
  gross 
  and 
  of 
  a 
  gray 
  color, 
  four 
  hours 
  in- 
  

   stead 
  of 
  two 
  should 
  be 
  taken 
  to 
  each 
  stage 
  from 
  100° 
  to 
  

   120°. 
  

  

  The 
  Ragland 
  Method. 
  — 
  This 
  method 
  is 
  for 
  medium 
  to- 
  

   bacco. 
  Ripe 
  tobacco 
  only 
  is 
  to 
  be 
  cut, 
  and 
  is 
  then 
  placed 
  five 
  

   to 
  seven 
  plants 
  on 
  a 
  stick 
  4 
  feet 
  long 
  and 
  from 
  10 
  to 
  12 
  inches 
  

   apart 
  on 
  the 
  tier 
  poles. 
  Steaming 
  or 
  yellowing 
  is 
  done 
  at 
  

   90° 
  from 
  eighteen 
  to 
  forty-eight 
  hours, 
  according 
  to 
  char- 
  

   acter 
  of 
  tobacco. 
  When 
  yellowed, 
  the 
  heat 
  is 
  raised 
  from 
  ' 
  

   90° 
  to 
  95° 
  in 
  from 
  one 
  to 
  tw^o 
  hours, 
  from 
  95° 
  to 
  100° 
  in 
  

   two 
  hours, 
  from 
  100° 
  to 
  105° 
  in 
  two 
  hours, 
  from 
  105° 
  to 
  

   110° 
  in 
  from 
  one 
  to 
  three 
  hours, 
  from 
  110° 
  to 
  115° 
  in 
  two 
  

   hours, 
  and 
  from 
  115° 
  to 
  120° 
  in 
  two 
  hours, 
  at 
  which 
  the 
  

   leaf 
  is 
  cured 
  in 
  from 
  four 
  to 
  eight 
  hours. 
  The 
  stalk 
  is 
  cured 
  

   by 
  a 
  temperature 
  advancing 
  from 
  120° 
  to 
  175°, 
  at 
  about 
  5°
