Females from No. 5 mated back to the original male, No. 2, produce 

 group 8, that are } the blood of No. 2, and a cockerel from No. 4, mated 

 back to the original dam, No. 1, produces group No. 6, that is i the blood 

 of the original dam, and only \ the blood of the original sire. 



Agfun we select a male from No. 8 and females from No. 6 and a third 

 tune produce chicks (in group No. 11) that are half the blood of the origi- 

 nal pair. This is the third step and the 9th mating in securing complete 

 breeding of our new strain. In all of this we have not broken the line of 

 sires, for everyone has come from a group in which the preponderance of 

 blood was that of the original sire, Noa. 8, 13 and 18 are virtually the 

 blood 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. 4 and produce group 9, 

 which is thirteen-mxteenths the blood of the origuial dam No. 1, and three- 

 sixteenths the blood of the original sire. 



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

 11, and produce group 14, which becomes |^ of the blood of the original 

 dam, thus preserving her strain of blood. 



A male from No. 13, which is tbirteen-sixteenths the blood of the 

 original sire No. 2, mated to females from No. 10, which are five-sixteenths 

 the blood of the original sire. No. 2, gives us group 17, which is nine-six- 

 teenths the blood of sud sire. 



While in No. 16 we have the new strain and in No. 18 the strain of 

 our original sire, No. 2, we have three distinct strains, and by and with 

 this systematic use we can go on breeding for all time to come. Remem- 

 ber that each dotted line is a female selection and each solid line the 

 male selection.
