124 SYSTEMATIC POMOLOGY

 American Pomological Society in its official 

 proceedings, in its fruit exhibits and in its 

 published reports. Only here and there do 

 the rules give one the feeling that the men 

 who framed them expected them to have any 

 force or application outside the society. In 

 this respect they differ essentially from the 

 Lazy Club rules, which were designed to 

 express the fundamental laws of nomencla- 

 ture as applied to pomology. 



It is evidently easier to make rules for a 

 society than for the whole world, and inestima- 

 bly easier to enforce such rules. But, ideally, 

 the rules of nomenclature should rest on uni- 

 versal laws, or, at least, the rules themselves 

 should have universal recognition. Perhaps 

 the best expression of this point was the one 

 given long ago, written, I believe, by De 

 Candolle, saying that science " can make no 

 real progress without a regular system of 

 nomenclature, acknowledged and used by a 

 large majority" of the men engaged in a

Another closely related principle was ex-
