 out of the old orbit into the * mutation ' or ' sport ' 

 condition. Radical changes of environment for 

 a series of generations will produce a tendency to 

 sport, but hybridization will bring it about far 

 more abruptly, and for practical plant or animal 

 breeding or for scientific study of all these varia- 

 tions, far more satisfactorily/' 



*'The misunderstanding evidently comes from 

 not having a clear knowledge of latent and domi- 

 nant hereditary forces. A knowledge of these 

 explains the whole matter and makes harmony 

 between Darwin and Wallace, leaving Professor 

 De Vries careful experiments good, but coming 

 to different conclusions on the results." 



''Professor Hubrecht also states that 'now for 

 the first time — forty years after the appearance of 

 the 'Origin of Species — the actual birth of a 

 species has been observed by him.' As I have 

 produced several good species by hybridization, 

 apparently as good as nature herself has produced, 

 and as others have done the same by selection
