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. 

 Al .. ..108 A10 .. ..95 



A4 .. ..105 All .. .. 118 



A6 .. ..114 



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. 



2 Al. 



3 Commercial sample. 



4 Al. 



5 Commercial sample. 



6 A6. 



7 Commercial sample. 



8 A6. Etc. 



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: 



These results are displayed in graphic form opposite. 

 The graph shows the plots in the same order as they 

 occurred in the field.
