year period show that the average yield of grain and straw 

 and the weights per measured "bushel were in favor of large 

 plump seed as against either medium size or small seed. 



7/ith oats the Aberdeen and lorth of Scotland Agricul- 

 tural College (22} found that when equal "bulks of small and 

 large seed were planted the "results were slightly in favor 

 of the small seed*. The two lots of seed were selected 

 from the same field. . 



The \Vest of Scotland Agricultural College (23) reports 

 a series of experiments with oats in which the oats were di- 

 vidAd into (a) singles, or kernels that hear rudiments that 

 might have developed into "bosom oats, ("b) and firsts, or 

 oats in which the rudiments did so develop. The small seeds 

 are made up of seconds or "bosom oats broken from the firsts. 

 The firsts produced heavier yields of straw and grain than 

 either the seconds or the singles. The seconds produce^ more 

 straw and less grain per acre than the singles. The differences 

 reported range from twenty- three to thirty- six per cent in 

 terms of the weights yeilded hy the singles.
