226  Report  on  the  Field  and  Feeding  Experiments  at  Woburn. 
The  wheat  on  plot  1,  it  will  be  seen,  weighed  6T3  lbs- 
per  bushel,  and  on  plot  2 nearly  61  lbs.,  whereas  on  the  two 
plots  top-dressed  with  nitrate  of  soda  it  weighed  1 lb.  less 
per  bushel. 
On  the  whole,  the  quality  of  the  wheat  was  superior  to  that 
in  the  Rotation  Experiments  of  the  preceding  year. 
On  the  other  hand,  the  yield  of  corn  was  considerably  less 
last  season  on  all  the  four  acres  than  in  1881,  when  from 
14  to  19  bushels  more  wheat  were  grown  than  last  season. 
The  nitrate  of  soda  on  plot  3 appears  to  have  done  more 
harm  than  good,  for  the  yield  of  dressed  wheat  on  that  plot 
was  less  than  on  any  of  the  remaining  three  acres. 
On  all  the  four  acres  the  quantity  of  straw  reaped  was  much 
greater  last  season  than  in  1881.  Thus  plot  1,  which  in  round 
numbers  produced  14  bushels  less  head-wheat  than  the  corre- 
sponding plot  in  No.  4 Rotation  the  preceding  year,  grew 
8 cwts.  3 qrs.  and  20  lbs.  more  straw  than  plot  1 in  the  Rota- 
tion wheat  in  1881. 
On  all  the  four  acres  more  straw  was  grown  in  1882  than  on 
the  four  acres  of  the  Rotation  wheat  of  1881. 
Rotation  No.  2. — Four  acres:  1877,  mangolds;  1878,  barley;. 
1879,  seeds  ; 1880,  wheat ; 1881,  mangolds  ; barley,  1882. 
Barley,  1882. — The  mangolds  grown  in  1881  were  fed-off 
on  the  field  in  spring ; the  land  was  ploughed  in  the  beginning 
of  April,  and  the  barley  drilled  in  on  the  22nd  of  April,  1882. 
White  Dutch  clover  was  sown  between  the  barley  in  May,  no 
manure  was  applied  to  plots  1,  2,  and  4.  On  plot  3 the  barley 
was  top-dressed  on  the  13th  of  June  with  124  lbs.  of  nitrate 
of  soda,  containing  one-third  as  much  nitrogen  as  the  manure 
from  1000  lbs.  of  decorticated  cotton-cake. 
With  the  exception  of  a small  piece  of  the  barley  field  fed-off 
last  by  the  sheep,  where  the  barley,  owing  to  the  treading  of  the 
sheep  in  wet  weather,  was  backward,  the  rest  of  the  field  grew  a 
splendid  crop  of  barley. 
The  barley  was  cut  on  the  11th  of  September  and  carted  in 
good  condition,  and  stacked  on  the  15tli  of  September. 
It  was  threshed  out  in  the  field  on  the  27th  of  October,  and  j 
the  corn,  after  having  been  stored  in  the  granary,  was  winnowed, 
measured,  and  weighed  on  the  23rd  of  November.  The  results 
of  the  harvest  are  shown  in  Table  IV. 
It  will  be  seen  that  by  far  the  best  crop  was  obtained  on  the 
cotton-cake  plot,  No.  1.  This  plot  produced  47*6  bushels  of 
dressed  head-corn,  weighing  nearly  52  lbs.  per  bushel,  and  1 ton 
14  cwts.  and  24  lbs.  of  straw  ; whilst  the  maize  plot,  No.  2,  yielded 
44'5  bushels  of  head-corn  and  1 ton  13  cwts.  3 qrs.  and  27  lbs.  of 
straw,  or  about  3 bushels  less  head-corn  than  the  cotton-cake
