ings from this type of head would not produce very fertile 

 eggs, and the progeny would deteriorate each year if they 

 were bred from stock with heads like this. If the parents were 

 200 egg type, their egg yield and vitality would be reduced 

 each generation of breeding. If they were of the beef type 

 their vitality and ability to produce flesh economically would 

 diminish with each generation. If they were a fancy type the 

 breeder would be up aganst a stone wall of discouraging ex- 

 periences.

I would advise the reader to take specilal notice of figure 

 43, as this cut shows the method of determining prepotency 

 plainer than any of the others. 



Cut No. 41 shows a hen with prepotency full, i. e., thumb 1-8 

 of an inch behind forefinger. Sometimes a poultryman will be 

 lucky enough to mate up a lot of pens of the right type for his 

 purpose with heads like Nos. 41, 42, and 43. His 

 business prospers and his neighbors call him lucky.
