means of a fanning mill. The experiments were continued 

 for three years, each year taking seed not grown from seed 

 so selected. The results showed an average gain for large 

 seed of two and one half bushels per acre. 



Georgeson, at the Kansas Experiment Station, has done con- 

 siderable work on the subject and we find the results of his 

 work in several of the publications of that station. In 

 Bulletin No. 13 the following results are presented: 



Grade of seed Yield of grain per A. 



Light 21.6 bu. 



Common 24.0 " 



He avy SO . " 



These tests, he says, prove "only what is already 

 well known". 



He later seeded plats with seed of different weights 

 per bushel and one of seed from selected heads. The grades 

 were as follows: 



Light seed 56 Ibs. per bu. 

 Common seed 62.5 62.5 " 

 Heavy seed 63 " " n 

 The seed from selected heads. 



Each year seed was selected from wheat not grown from selec- 

 ted seed. The average results from three years trials were 

 as follows: 



Grade of seed Bu. of grain per acre. 



Light 25.19 



Common 26.57 



Heavy 27.07 



Select (Average for two years) 25.82 



In Bulletin So. 54 of the same station the average for 

 six years shows as follows: 



Light 8.48 



Medium 29.85 



Heavy 30.76
