separate plots, again with several plots of commercial 
seed for comparison. The yields in the harvest of 1912 
were as follows :— 
Average of Commercial Seed Plots 100.

Of these, Al, A6, and All were kept for further trial, 
and their seed was sown in 1912, in large duplicated plots 
each about an acre in extent. The arrangement of the 
plots was as follows :— 
Plot 1 Commercial sample.

It is now perhaps time to refer to the ‘‘commercial 
sample’’ used as the basis of comparison. 
Five or six of the leading grain merchants in Christ- 
church were each asked for a bushel of the best Hunter’s 
seed they had in stock. The grain received was all mixed 
together and the resultant sample was considered as an 
average of the best seed of the variety a farmer 
could procure under the conditions then obtaining. 
The progeny of this seed has been used as the standard 
in the subsequent trials. 
The harvest of 1913 showed the following results :—
