Fe/cA Breeding Chart Applied to Line Described in Text. 



Females from No, 8 mated back to the original male, No. 2, produce group 8, that are i the- 

 blood of No. 2, and a cockerel from No. 4, mated back to the original dam, No. 1, produce* 

 group No. 6, that Is J the blood of the original dam, and only i the blood of the original sire. 



Again we select a male from No. 8 and females from No. 6, and for a third time produce 

 chicks (in group No. 11) that are half the blood of the original pair. This is the 3d step, and 

 the 9th mating in securing complete breeding of our new strain. In all this we have not 

 broken the line of sires, for every one has come from a group in which the preponderance of 

 blood was that of the original sire. Nos. 2, 8, 13, and 18 are virtually the blood of No. 2. 



We have reached a point where we would establish a male line whose blood is virtually that, 

 of our original dam, and we now select from No. 6 a male which we mate with a female from 

 No. i and produce group 9, which is 13-16 the blood of the original dam No. 1, and 3-16 the 

 blood of the original sire. 



Again we select a male from No. 9 and a female of the new strain. No. 1, and produce 

 group 14, which becomes 21-32 of the blood of the original dam, thus preserving her strain 

 of blood.
