threshing,  and  this  probably  accounts  largely  for  the  seemingly 
low  produce  of  this  plot  in  comparison  with  the  others,  for 
there  should  be  no  general  reason  for  its  produce  being  lower 
than  that  of  plot  2,  especially  as  the  straw  is  about  the  same 
in  the  two  cases. 
This  concludes  the  account  of  the  Rotation  Experiments 
of  1909,  and  it  is  intended  when,  on  all  the  rotations,  a 
full  four-years’  course  has  been  completed,  to  put  together 
the  results  and  to  set  out  the  conclusions  to  be  drawn  from 
them. 
Green-Manuring  Experiment  {Lansome  Field),  1909. 
In  this  season  the  green  crops  were  to  be  grown  on  the 
.different  plots,  and  it  was  decided  to  follow  them,  as  before, 
with  wheat  in  1910.  The  land  was  ploughed  and  winter  tares 
were  drilled  on  October  22,  1908,  on  plots  1 and  2,  mineral 
manures  (superphosphate  and  sulphate  of  potash)  being  applied 
at  the  same  time  to  plot  1,  The  tares  came  up,  but  gave  only
