It will be seen that the Daubeney variety is one of great promise, 

 when the complete results are taken into consideration. The Daubeney 

 variety grows a good length of straw, stand up very well, has a spread- 

 ing head and white grain, and the g-rain is very thin in the hull. 



Continuous Selection of Seed Oats for Twelve Years in Suc- 

 cession. For twelve years in succession, an experiment has been con- 

 ducted in breeding oats by means of the selection of the seed. The 

 selections made were large, plump, well-developed seeds : light-weigh- 

 ing and light-colored seeds ; and also seeds from which the hulls had 

 been removed by the separator. The test was commenced in the 

 spring of 1903, by selecting seed from the general crop of the Joan- 

 ette Black oats of the previous year. The selection made in each of 

 the following- years has been from the product of the selected seed of 

 the previous year. The number of grains used on each plot was care- 

 fully counted and an equal number was used of each selection in each 

 year. As the selection for this experiment has been continuous, select- 

 ing- the seed each year from the crop produced in the year previous, 

 the average results are of but little value, but the final results are in- 

 teresting, valuable, and quite suggestive. In the crop produced in 

 1904, it was found that the larg^e plump seed produced 94.1 bushels; 

 the light seed, 68 bushels; and the hulled seed, 91.6 bushels per acre. 

 As only the best quality of seed becomes hulled, we find that the oats 

 from which the hulls had been removed gave nearly as good results 

 as the carefully selected, large, plump seed from which the hulls had 

 not been removed in the process of threshing. In weig-ht per measured 

 bushel, the crop produced from the large plump seed weighed 34.5 

 pounds; from the light seed, 24 pounds, and from the hulled seed, 

 33.1 pounds. The difference, therefore, between the large, plump, well- 

 developed seeds and the light-weighing and light-colored seeds is very 

 marked, and shows the great importance of sowing the former and dis- 

 carding the latter. It is interesting to notice that the crop producing-
