entire  rotation,  and  lime  at  the  rate  of  2 tons  per  acre  was 
put  on  April  3-4,  1909.  Previous  to  this  the  land  had  been 
ploughed,  December  22-28,  1908,  and  a second  time  on  January 
4,  1909.  On  June  8 “Invicta”  swede  seed  was  drilled  all 
over  the  rotation. 
(a)  UPPER  HALF  (Sheep-feeding). 
On  this  half  the  swede  seed  was  drilled  with  4 cwts.  per 
acre  of  basic  superphosphate  and  1 cwt.  per  acre  of  sulphate 
of  potash.  A good  plant  came,  and  was  singled  July  10-30. 
Early,  however,  in  August  the  swedes  showed  signs  of  “ going 
off,”  and  this  increased  as  time  went  on,  “ finger  and  toe  ” 
being  very  marked  and  causing  considerable  “ blanks  ” in  the 
crop.  The  swedes  were  left  until  December  6,  when  they  were 
pulled  up,  the  weights  being  subsequently  taken.  These  are 
given  in  Table  III. 
(&)  LOWER  HALF  (Bullock-feeding). 
The  farmyard  manure,  made  by  bullocks  during  the 
previous  winter,  and  then  stored,  well  covered  with  earth, 
was  carted  out  and  spread  May  25-28,  1909,  after  which  it 
was  ploughed  in.  Plot  5 had  dung  made  with  decorticated 
cotton  cake,  plot  6 that  made  with  maize  meal,  while  plots  7 
and  8 had  dung  made  with  roots,  chaff,  and  hay  only.  The 
weight  actually  applied  was  4 tons  per  acre.  Swede  seed  was 
drilled,  as  stated,  on  June  8.  The  swede  crop  on  this  half 
was  decidedly  better  than  on  the  upper  half,  and  “ finger  and 
toe,”  though  not  absent  altogether,  was  not  nearly  so  prevalent. 
The  results  are  given  in  Table  III.
