The  wheat  came  up  well  on  all  the  plots,  and,  owing  to  the 
mild  winter,  grew  well  and  looked  healthy  and  strong  on  all 
of  them  in  February. 
Towards  the  end  of  Ma^  the  wheat  was  in  a fine  growing 
condition,  and  scarcely  a single  weed  could  then  be  noticed  in 
the  Experimental  field,  either  on  the  wheat  or  on  the  barley 
plots. 
On  the  17th  of  June  the  wheat  began  to  come  into  ear,  and 
towards  the  end  of  the  month  bloomed  well. 
On  the  19th  of  July  I took  the  following  notes  in  the  field 
on  the  appearance  of  the  crop  : — 
Plot  1 (unmanured).  Wheat  thin,  and  knocked  down  in 
places. 
Plot  7 (duplicate  unmanured  plot).  Wheat  thin,  but  healthy, 
knocked  about  a good  deal  by  wind,  rather  better  than  on 
plot  1. 
Plot  2 (ammonia-salts  alone).  WTheat  looks  very  well. 
Plot  3 (nitrate  of  soda  alone).  Wheat  looks  very  well,  no 
perceptible  difference  between  plots  2 and  3. 
Plot  4 (minerals  alone).  Slightly  better  than  the  unmanured 
plot  7. 
Plot  5 (minerals  and  ammonia).  Much  better  than  plot  2 
(ammonia-salts  alone)  ; promises  to  turn  out  a good  crop. 
Plot  6 (minerals  and  nitrate).  About  the  same  as  plot  5. 
Plot  8a  (minerals  alone,  ammonia-salts  left  out  in  1882). 
Scarcely  better  than  No.  4. 
Plot  8b  (minerals  and  ammonia-salts).  Wheat  remarkably 
strong  and  healthy,  not  knocked  down  nor  mildewed  in  the 
least. 
Plots  9a  and  9b  (minerals  with  and  without  nitrate  of  soda). 
The  same  condition  as  in  8a  and  8b.  No  perceptible  dif- 
ference in  the  appearance  of  the  8 and  9 plots. 
Plot  10a  (no  dung  in  1882).  Wheat  thin,  and  a good  deal 
knocked  about  by  rain  and  wind. 
Plot  11a  (no  dung  in  1882).  Wheat  thin. 
Plot  10b  (small  dose  of  dung).  Wheat  somewhat  better 
than  on  10a.
