The  Woburn  Field  Experiments,  1910. 
So  far  as  the  upper  half  of  the  rotation  is  concerned,  the 
wheat  crop  of  1910  brought  to  a close  the  four-course  series 
on  Rotation  II.  since  the  adoption  of  the  new  plan  of  experi- 
ment ; Rotation  III.  was  similarly  concluded  with  the  wheat 
crop  of  1909,  while  Rotations  I.  and  IY.  closed  respectively  in 
1908  and  1907.  On  the  lower  half,  Rotation  II.  was  the  only 
one  to  complete  the  full  four-course  with  the  wheat  crop  of 
1910,  Rotation  I.  reaching  its  second,  and  Rotation  IV.  its  third, 
crop  under  the  new  plan. 
It  is  not  proposed  to  carry  this  on  further,  but  to  summarise 
the  results  and  to  renew  the  inquiry  on  somewhat  different 
line3.  This  will  commence  in  1911. 
Green-manuring  Experiment  ( Lansome  Field),  1910. 
In  1910  wheat  followed  on  the  growing  and  ploughing-in 
of  the  green  crops  of  1909.  The  land  was  ploughed  in  Sep- 
tember, 1909,  and  subsequently  cultivated.  On  November  10 
“ Square  Head’s  Master  ” wheat  was  drilled  at  the  rate  of  9 
pecks  per  acre.  Though  somewhat  weakened  by  frosts,  it 
came  a fair  crop,  that  after  tares  ploughed-in  looking,  as  usual, 
good  at  first,  but  later  on  it  fell  far  behind  the  other  two,  there 
being  little  to  choose  between  the  rape  and  the  mustard  plots. 
The  crop  was  cut  on  August  20,  1910,  carted  September  2,  and 
subsequently  threshed  and  weighed.  The  harvest  results  are 
given  in  Table  VII.
