field.  The  wheat  looked  better  both  on  the  mustard  and  the 
rape  plots  than  after  the  tares,  and  the  experience  of  previous 
years  was  again  I’epeated.  Of  the  two  former,  the  rape  at  first 
looked  the  better,  but,  later  on,  the  mustard. 
The  wheat  was  cut  on  August  19,  1903,  and  carried  and 
stacked  on  August  31.  The  weights  of  produce — given  in 
Table  V.,  page  29o — quite  bore  out  the  appearances  shown  in 
the  field.  The  highest  yields  were  given  l)y  the  mustard  plot, 
the  next  by  the  rape,  and  the  lowest  by  the  tares,  thus  con- 
firming the  results  of  1899  and  1901.  It  is  noticeable,  however, 
that  now,  for  the  first  time,  there  was  a marked  benefit  arising 
from  the  use  of  mineral  manures.  These  results,  following  on 
the  discussion  of  last  year's  figures,  leave  this  experiment  a 
very  interesting  one,  calling  for  further  investigation  in  view 
of  the  fact  that  the  conclusions  are  the  opposite  of  those  to 
which  theoretical  considerations  would  tend.  It  has  been 
suggested  that  a single  corn  crop  is  not  enough  to  take  out,  or 
fully  utilise,  the  nitrogen  that  has  been  stored  uj)  l>y  the  green 
crops,  and  so  it  is  proposed  to  take  a second  corn  crop  after 
this.

The  great  attention  which  has  lieen  paid  of  late  to  the 
differences  between  English  wheat  and  imported  wheat,  more 
especiallj’  in  respect  of  the  “ strength  ” ' of  the  latter  and  its 
better  milling  qualities,  led  to  the  institution  of  experiments  at 
the  Woburn  Farm,  simultaneously  with  those  carried  on  at  various 
other  places.  These  were  the  outcome  of  a series  of  investiga- 
tions, conducted  on  behalf  of  the  National  Association  of  British 
and  Irish  Millers,  by  a Committee  of  the  Association,  the 
principal  work  of  which  was  carried  out  by  Mr.  A.  D.  Hall, 
M.A.,  Director  of  the  Rothamsted  Experimental  Station,  and 
Mr.  A.  E.  Humphries,  of  Coxes  Lock  Mills,  Weybridge. 
The  object  of  the  inquiry  was  to  find  out  how  increased 
“strength,”  such  as  is  possessed  by  imported  wheats,  could  be 
combined  with  the  high  produce  of  home-grown  wheat.  The 
immediate  purpose  in  the  trial  at  Woburn  was  to  grow  the  seed 
of  imported  varieties  and  to  ascertain  how  its  yield  compared 
with  English  wheat  on  the  same  class  of  land,  and  snbsequentlj' 
to  test  the  milling  and  baking  qualities  of  the  two.  A further 
question  arose  as  to  whether  the  imported  wlieat  should  be 
sown — as  usual  in  tliis  countrj' — in  autninn,  or  else  in  the 
spring.  Early  in  1902  sami)les  of  three  kinds  of  Canadian 
wheat  were  received  from  Dr.  Saunders,  of  Ottawa,  viz..
