( Very  poor  wheat,  small

Cui'ious  sample  of  wheat, 
full  av(‘rage  strength,  but 
there  is  an  absence  of 
bloom,  and  handles  very 
badly 
Would  have  been  an  aver- 
age wheat  in  ordinary  sea- 
sons; it  is  badly  weathered, 
contains  many  sproutea 
corns,  ami  is  in  very  bad 
condition 
Strong  wheat,  but  not  well 
matured;  thin  in  berry 
Fair  average  sample  for 
season  ; it  is  not  so  well 
grown  as  plot  7,  but  better 
harvested  than  plot  3

ing value 
{Coloury,  well-grown  wlu‘at, 
stronger  than  plot  5,  being 
decidedly  the  strongest

Sound  wheat,  being  an 
average  sample  for  the 
season,  but  it  is  not  so  well 
grown  as  plot  8a 
/Much  the  same  as  plot  8 b, 
\ slightly  inferior  in  growth 
1 and  colour 
These  plots,  together  with 
plot  1,  were  classed  as  of 
eijual  valiu‘,  all  being  yel- 
low and  without  strength

Poor,  weak,  common  lot  of

1 Ammonia  salts  are  equal  weights  of  sulphate  of  ammonia  and  muriate  of  ammonia. 
2 Mixed  mineral  manures  are.  throughout,  3J  cwt.  superphosphate  of  lime,  200  lb.  sulphate  of 
potash.  100  lb.  sulphate  of  soda,  100  lb.  sulphate  of  magnesia  per  acre.
