THE CALL OF THE HEN. 77 
deal more than half the flock. If I mate 100-egg type cock birds with 
200-egg hens, the progeny may lay about 150 eggs, thus reducing my 
egg-yield about 25 per cent in the progeny of each of the twelve hens. 
For this reason I have given as much thought to the male bird as I have 
to the hen; and in arranging the charts for the male birds have experienced 
a great deal of difficulty, as it takes years of time and hundreds of matings 
to arrive at conclusions that would be approximately correct. In any 
one case, everything else (type, capacity, and breed) being equal, care 
and environment have a dominating influence on the product, whether 
eggs or meat; consequently, if a number of investigators were working 
on this proposition, using the same system of selection, they could not 
help but arrive at somewhat different conclusions as to figures, but that 
would not affect the value of the system.
