Report  on  the  Field  and  Feeding  Experiments  at  Woburn.  23  L 
the  four  remaining  bullocks  were  fed  upon  mangolds  and 
straw-chaff  only. 
The  bullocks,  when  put  into  the  feeding-boxes  on  the  13th  of 
December,  1881,  weighed 
cwts.  qrs.  lbs. 
19  2 8 — receiving  decorticated  cotton-cake. 
20  1 5 — receiving  maize-meal. 
19  3 4 — no  corn  or  cake.

The  bullocks  which  were  fed  only  upon  mangolds  and  wheat- 
straw  chaff  finished  the  allotted  amount  of  food  on  the  1st 
of  February,  1882,  and  the  bullocks  which  consumed  decorti- 
cated cotton-cake  or  maize-meal  as  additional  food,  on  the 
28th  of  January,  1882. 
When  taken  out  of  the  pits  on  these  dates  the  bullocks 
weighed :

cake  as  additional  food 20  2 5

The  first  lot  gained  109  lbs.  in  live-weight  ; the  second  lot, 
139  lbs. ; the  third  lost  57  lbs. ; and  the  fourth  lost  3 lbs. 
All  the  bullocks,  before  they  were  put  into  the  feeding-boxes, 
were  fed  upon  some  corn  and  cake  ; and  when  the  concentrated 
food  was  withheld  from  four  of  the  bullocks,  they  went  back  a 
good  deal  at  first,  as  they  did  not  take  kindly  at  once  to  the 
plainer  food  ; but  gradually  they  came  round,  towards  the  con- 
clusion of  the  experiment,  and  if  they  had  been  kept  longer  in 
the  feeding-boxes  they  probably  would  have  maintained  better 
their  original  weight.  The  dung  was  turned  over  once,  and 
kept  under  cover  until  the  20th  of  February,  1882,  when  it  was 
carted  on  the  field  in  a rotten  condition,  and  subsequently 
ploughed  in. 
The  mineral  manures  were  applied  on  the  8th  of  June,  on 
which  date  the  swedes  were  sown.  The  nitrate  of  soda  on 
plots  3 and  4 was  sown  by  hand  round  the  swedes  on  the  26th 
of  July,  after  they  had  been  singled  out  and  had  made  some 
progress  in  growth  and  had  begun  to  bulb. 
The  roots  were  taken  up  in  the  second  week  of  December, 
1881,  topped  and  tailed,  and  the  whole  produce  of  the  four 
acres  (bulbs  and  tops),  was  weighed,  when  the  results  shown  in 
Table  V.  were  obtained  : —
