372  The  Woburn  Field  Experiments,  1909. 
It  will  be  noticed  tbat  neither  in  the  upper  half  nor  the 
lower  was  there  anything  to  bring  out  the  believed  superiority 
of  the  cotton  cake,  whether  fed  directly  on  the  land  or 
whether  put  on  in  the  form  of  farmyard  manure.  The  in- 
equalities in  the  duplicate  plots  3 and  4 were  due  to  “ finger 
and  toe,”  which,  indeed,  affected  the  yields  of  plots  1 to  4 
throughout. 
Rotation  II.  1909,  Green  crop  {Mustard) — after  Barley  (1908) . 
The  land  was  ploughed  at  the  end  of  October  and  beginning 
of  November,  1908,  and  again  June  5-9,  1909.  Lime  at  the 
rate  of  2 tons  per  acre  was  spread  over  the  whole  rotation 
April  5-7,  1909.  On  July  20  white  mustard  seed  was  drilled, 
but  the  crop  came  up  very  patchily,  and  on  August  16  fresh 
seed  was  drilled  where  the  first  crop  had  failed.  This 
came  better,  and  the  crop  was  cut,  carted  and  weighed 
September  16-17.  The  results  are  given  in  Table  IV.

Though  the  crop  was  irregular  and  patchy,  the  cake 
manuring  (given  in  1907)  would  appear  to  have  “ told  ” on 
both  halves. 
Rotation  III.  1909,  Wheat — after  Mustard  (1908). 
The  land  on  which  mustard  had  been  grown  in  1908  was 
ploughed  October  8-13,  1908,  and  prepared  for  wheat, 
which  was  drilled  October  14,  9 pecks  per  acre  of  “ Street’s 
Imperial  ” wheat,  obtained  from  Driffield,  Yorks,  being  sown. 
Early  in  1909  the  wheat  looked  fairly  well,  but  was  markedly 
better  on  the  upper  (sheep-fed)  half  than  on  the  lower  half. 
The  crop  was  cut  August  19,  but,  owing  to  bad  weather,  could 
not  be  carted  and  stacked  until  September  7.  The  harvest 
results  quite  bore  out  the  appearances  of  the  different  plots. 
These  results  are  given  in  Table  V.
