plot.  Nearly  the  same  weight  of  corn  and  straw  as  on  the 
maize  plot  was  grown  on  the  unmanured  plot  4,  upon  which  the 
clover  had  been  fed-off  by  sheep  which  received  neither  maize 
nor  decorticated  cotton-cake  as  additional  food. 
The  top-dressing  of  nitrate  of  soda  on  plot  3 appears  to 
have  done  some  harm  to  the  barley,  for  more  straw  was  grown 
on  that  plot  than  on  any  other  of  the  four  acres  of  the  Rotation 
barley.  On  this  plot  the  produce  of  head-corn  was  42'6  bushels, 
or  5 bushels  less  than  on  the  cotton-cake  plot  1,  and  that  of 
straw  was  1 ton  16  cwts.  1 qr.  and  4 lbs.,  or  2 cwts.  and  8 lbs. 
more  than  on  plot  1. 
On  the  whole,  the  Rotation  barley-crop  in  1882  was  fully  as 
good  as  in  the  preceding  year.

Seeds,  1882. — The  clover — white  Dutch — was  fed-off  by 
sheep  in  the  course  of  the  growing  season.  On  one  acre, 
672  lbs.  of  decorticated  cotton-cake  were  consumed  ; on  the 
second  acre,  728  lbs.  of  maize-meal  ; on  the  third  and  fourth 
acres  neither  cake  nor  maize  was  given  to  the  sheep  which  fed- 
off  the  clover  on  plots  3 and  4.  Fresh  water  was  supplied  to 
all  the  sheep  in  the  field.  Forty  sheep— ten  on  each  acre — were 
put  on  the  clover  on  the  22nd  of  May  ; and  by  the  23rd  of  June 
the  sheep  on  plot  3 had  eaten  down  the  clover,  on  plot  4 on  the 
26th  of  June,  and  plots  1 and  2 on  the  28th  of  June.  They 
were  weighed  before  they  were  put  on  the  Rotation  clover,  and 
again  when  they  were  taken  off.  The  following  results  were 
obtained  : —

The  clover  was  somewhat  immature,  and  not  over-abundant, 
when  the  sheep  were  put  upon  it  for  the  first  time.  This 
explains  the  greater  increase  of  live-weight  of  the  sheep  which 
consumed  cake  or  corn  as  additional  food. 
The  sheep  which  received  decorticated  cotton-cake  made  the 
largest  increase  in  live-weight,  and  on  plot  4 they  did  the
