NEW CREATIONS IN PLANT LIFE 



road. They stand about fifteen feet high, they 

 are perhaps six inches in trunk diameter. 

 These trees belong to a past generation; the 

 noble trees on his side of the road are of the 

 progressive today. In fourteen years the new 

 tree grew six times as much as the older tree 

 had grown in thirty years. In addition to 

 their specifically economic value, the new 

 trees are very beautiful, making an ideal tree 

 for shade in private grounds, for an avenue 

 approaching some country estate, to over-arch 

 in gothic strength some beautiful city street. 

 Along with the production of this tree 

 which Mr. Burbank named the "Paradox" he 

 worked on a different combination, though 

 produced in the same way. The Paradox was 

 particularly suited to regions like California, 

 where winters are not severe. He wanted 

 another tree, as rapid in growth, as fine for 

 timber, as valuable for fuel, which would grow 

 in any climate where the hardy northern black 

 walnut would grow. So he joined together the 

 native California black walnut and the old- 

 fashioned New England black walnut, produc- 

 ing a new hybrid which he named the "Royal." 

 This tree has answered all the demands made
