BREEDING am 
the male and one-half of the blood of the 
female. 
The next mating, the father is mated to his 
own daughter and the mother to.son. This 
gives a generation having three-fourths of the 
blood of the original sire and only one-fourth 
the blood of the original dam. It also gives a 
generation having three-fourths the blood of 
the original dam and-only one-fourth the blood 
of the original sire. 
You will note that by each mating a point 
is; either gained or lost in the blood of: the 
stock. In fact. two separate blood lines are 
quickly established, a male and a female line. 
If you will carry. out the system as shown in 
the accompanying chart, you can soon have 
your males all looking like the original male 
and the females looking like the original female 
of. the line. 
The advantage of the system is such that it 
achieves this very purpose. It loses nothing 
and enables the breeder to preserve the char- 
acteristics of an especially valuable specimen.
