Result of using a pure-bred sire. The above pure-bred Barred Rock Cockerel 

 (Figure 48), crossed with the mongrel hen (Figure 49), produced a half-blood 

 pullet (Figure 50), weighing (average of the flock) 1.23 pounds more than 

 the mother hen. Another pure-bred cross on this pullet produced a three- 

 quarters-blood pullet (Figure 51), weighing (average) 0.59 pounds more than 

 her mother — An increase of nearly two pounds in two crosses. Note also 

 the improvement in breed type.
