The  four  bullocks,  according  to  these  data,  increased  in 
weight  at  the  rate  of  95  lbs.  per  week  ; or  on  an  average  each 
bullock  increased  in  weight  23§  lbs.  per  week,  or  about  3j  lbs. 
per  day. 
On  the  19th  of  July,  1882,  I took  in  the  field  the  following 
notes  respecting  the  appearance  of  the  barley  on  the  several 
plots. 
The  unmanured  plots  looked  remarkably  well,  considering 
that  barley  had  been  previously  grown  on  them  for  five  years 
in  succession. 
The  plots  dressed  with  nitrate  of  soda,  or  with  salts  of 
ammonia  only,  appeared  about  equal,  and  much  better  than  the 
unmanured  or  the  dunged  plots. 
Minerals  alone  (plot  5).  The  barley  was  not  stronger  than 
on  the  unmanured  plots,  but  was  lighter  in  colour,  and  more 
manured. 
The  plots  manured  with  minerals  and  the  smaller  quantity 
of  nitrate  of  soda  (plot  6),  or  with  minerals  and  ammonia-salts 
(plot  5)  were  about  equal.  The  barley  on  both  plots  was  very 
strong,  and  the  best  of  the  several  plots. 
On  the  two  dunged  plots  the  barley  was  not  so  strong  as  on  the 
plots  which  had  been  top-dressed  in  spring  with  nitrate  of 
soda,  or  with  ammonia-salts. 
Plot  8a  (minerals  without  ammonia).  Barley  not  much 
better  than  on  the  unmanured  plots. 
Plot  8b  (minerals  and  large  dose  of  ammonia-salts).  Barley 
down  on  the  ground. 
Plot  9a  (minerals  without  nitrate  of  soda).  Not  much  better 
than  the  unmanured  plots. 
Plot  9b  (minerals  and  large  dose  of  nitrate  of  soda).  Barley 
very  luxuriant,  a good  deal  down  on  the  ground,  though  scarcely 
as  much  as  on  plot  8b. 
The  barley  was  cut  on  the  21st  of  August,  1882  ; and,  rain 
intervening,  the  cutting  was  finished  on  the  25th  of  August.
