Tire RoTAL Walnut 



At ahout the time the Paradox was produced, 

 I undertook another series of hybridising experi- 

 ments with walnuts that resulted in a tree 

 •carcdy less anomalous. 



These experiments consisted of the maiitig of 

 the California walnut with the t^ack walnut of 

 the eastern United SUtes. The Utter tree pro- 

 duces perhaps the finest cabinet wood grown in 

 America, but it has almost disappeared from our 

 eastern forests owing to the rapadty and lack of 

 foresight of the lumberman. The California 

 and eastern walnuts are rather closely related, 

 yet the divergence is sufficient to give the 

 hybrid a character markedly diflferent from 

 either parrat 



In some respects this hybrid, which was 

 christened the "Royal/' showed characteristics 

 analogous to the Paradox. It had the same 

 tendency to extraordinary rapid growth, and in 

 subsequent generations it showed to a certain 

 extent the same tendency to produce a varied 

 company of dwarf and of giant progeny. There 

 was also a considerable variation in foliage, 

 although not the extraordinary diversity shown
