62 BAILEY—MOVEMENT IN PLANT-BREEDING. [April 2, 
price. Eventually the efficiency points of the grower and the 
commercial grades of the dealer ought nearly or quite to coin- 
cide. There should come a time when corn is sold on its inherent 
merits, as, for example, on its starch content. This corn would 
not then be graded 1, 2 and 3 on its starch content, because that 
content would be assured in the entire product ; but the Grade 1 
would mean prime physical condition, and the lower grades infe- 
rior physical condition. Eventually something like varietal names 
may be attached to those kinds of corns that, for example, grade 
fifteen per cent. protein. The name would be a guarantee of the 
approximate content, as it now is in a commercial fertilizer. 
Closely allied to the corn-breeding work of Illinois (which is 
carried on by the Experiment Station and also by a commercial 
firm organized for that purpose) is the wheat-breeding and flax- 
breeding work in Minnesota under the direction of Professor Hays. 
Mr. Hays’ aim has been chiefly to increase productiveness. The 
following sketch is made from his notes: 
‘‘ Here are three examples of increased efficiency produced at 
the Minnesota Experiment Station in co-operation with the U. S. 
Bureau of Plant Industry. 
‘‘Minn. No. 163 wheat was bred by selection from Fife parent- 
age. During three years’ comparison in field tests at University 
Farm, near Minneapolis, it averaged 2.7 bushels gain per acre, 
or eleven per cent., better than its parent variety, as shown by the 
following table:

eight of whom made the comparison between this and their com- 
mon wheats in a manner fair to both. The following table shows 
the average increased yield to have been 1.4 bushels per acre, or 
eight per cent.:
