GENETICS AND BREEDING 177 



world-old genetic laws have not radically modified 

 the successful animal breeders' methods. In 

 pointing out that a scientifically trained geneticist 

 is not as yet an absolutely indispensable necessity 

 on a successful animal-breeding farm I have no 

 thought or desire to belittle the importance of the 

 science of genetics. My zeal and enthusiasm for 

 the advance of knowledge in this field know no 

 bounds. This attitude, however, furnishes no 

 reason that the geneticist should delude himself, 

 or by rash statements hold out false hopes to the 

 breeder, as to the immediate practical importance 

 of some of the recent developments in the science of 

 genetics. All knowledge is potentially useful, but 

 the fundamental reason for undertaking and en- 

 couraging research in genetics, or anything else, 

 is not because what one gets may be immediately 

 useful, but because it is knowledge.
