THE ROYAL WALNUT 



trees of still wider diversity of form and growth. 

 Curiously enough the wood of the Paradox 

 walnut is exceedingly hard, even harder and more 

 close-grained than that of the ordinary black 

 walnut. This is surprising in view of the rapid 

 growth of the tree. Ordinarily trees that grow 

 rapidly have soft wood, as every cabinet-maker 

 knows. 



The Paradox further justifies its name by 

 producing a wood that has great firmness of 

 texture and is well adapted to take on a cabinet 

 finish. 



All in all the production of the Paradox hybrid, 

 and the development of a race of hard-wood trees 

 of exceedingly rapid growth, constitutes a genuine 

 triumph in tree culture. A tree that grows to 

 the proportions of a handsome shade tree and 

 furnishes material for the cabinet-maker in six or 

 eight years, has very obvious economic import- 

 ance. 



THE ROYAL WALNUT 



At about the same time when the Paradox was 

 produced, I undertook another series of hybrid- 

 izing experiments with walnuts that resulted in a 

 tree scarcely less anomalous. 



These experiments consisted of the mating of 

 the California walnut with the black walnut of 

 the Eastern United States. The latter tree pro-
