RT OF THE 
cee principles of selection to the breeding of bees with assurance of realizing results — 
“Ata, alike in kind and degree to those which have by the persistent application of the ~ a 
_... game laws and principles been realized in breeding all kinds of domestic animals. 
anal I have, by establishing mating stations in localities remote from other bees, secured ine 
. . the mating of queens and drones selected on account of their excellent paternity 
aaa and perfect development. 1 controlled the flight of the different varieties by the use 
“a, of queen-excluding zinc. By crossing selected individuals of different varieties, 
and by mating selected bees of the same variety avoided in breeding, I have laid _ 
gt the foundation for some ancestral stock of superior excellence. This kind of work ‘
