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
