TABLE 2 



Data on the fertility and hatching of eggs from random sample of untreated BPR 

 9 9 X untreated cf cf in 1915 



1 One egg was broken during incubation. 



division of table 1 show a high degree of fertility. Thus in the 

 case of the ethyl cf mating 2118 gave no infertile eggs out of a 

 total of 25 eggs set. Out of these 25 eggs were hatched 21 

 good chickens. In the case of mating 2113, with an ethyl 9, 

 this same ethyl cf had but 2 infertile eggs out of a total of 24 

 set. Anyone who has had experience with poultry knows that 

 records of this sort are not to be obtained with impotent or 

 defective males. The methyl cf made no record quite so good 

 as these of the ethyl d^ in respect to fertility of eggs. Mating 

 2125, however, with 9 eggs infertile out of 37 set shows that the 

 male was not seriously defective in his ability to fertilize eggs.
