NEW CREATIONS IN PLANT LIFE 



attention whatever. It is thought by culti- 

 vation and irrigation they would probably be 

 led to produce as much timber in eight or 

 ten years as they have done in fourteen years 

 with no aid. The Paradox will grow in any 

 climate similar to that of California, anywhere 

 where the English walnut will grow; the 

 Royal will grow anywhere in the United 

 States, or any other country, where the hardy 

 New England black walnut will grow. 



The secret of these wonderful trees lies in 

 the fact that Mr. Burbank selected them from 

 the most rapid -growing of all the many 

 thousands of seedlings he had under test, at 

 the same time taking into account all the 

 other characteristics that were essential. Enor- 

 mous rapidity of growth, so to use the words, 

 in the early life of the seedling has been main- 

 tained in after years so that these two trees 

 now stand at the head — the most rapid - grow- 

 ing trees in the temperate zones of the globe. 



They are deciduous, losing their leaves like 

 the elm and maple in the late autumn. 



In this, as in so many other lines of Mr. 

 Burbank's investigations, a new field is now 

 opened up for practical work. It now becomes
