14 Luther Burbank's Late Introductions 



English Walnut is hardy in Interlaken is sufficient evidence that the Paradox, which 

 is a cross between the English and the hardy California Black, will find conditions 

 throughout the eastern and western states, where there are great extremes of cold 

 in the winter months , congenial to its growth and development. Late observa- 

 tions clearly go to prove that the Paradox will stand frost much better than was 

 at first supposed. Advices based on actual experiments go to show that it will 

 grow well over the Pacific Coast States and Territories, throughout the South- 

 west, and the Gulf and Atlantic Southern States as far north as Pennsylvania, 

 and possibly throughout most of the northern States. 



Planting. Do not fail to dig the hole in which the tree is to be set, at least 

 two feet in diameter and two and one-half feet deep, and loosen up the soil as 

 deeply as possible in the bottom of the hole. When the tree is set, the collar 

 should not be more than two inches below the surface of the ground. The 

 planter should always bear in mind that the soil must always be well packed 

 around the roots at the time of planting. 



Winter Protection. In every cold climate, for at least two years after the 

 trees are planted, they should be wrapped with corn stalks. Rye straw would 

 answer if corn stalks are not available. 



Nuts. For some unexplainable reason this variety never produces many nuts 

 and those that are produced are retained by Mr. Burbank for planting with a 

 view, by selection, of still further improving this tree. 



Timber. The wood of the Paradox Walnut is in every respect the equal 

 of the celebrated Cashmere Walnut lumber now so extensively used for picture 

 framing. It works up smoother and has a finer compact grain than the ordi- 

 nary Black Walnut. As the tree grows several times faster, often averaging 1% 

 inches in diameter annually on good soil in California, it certainly possesses un- 

 usual attractions to the timber grower. Its parent, the common English Walnut, on 

 cultivated ground at Santa Rosa, California, at thirty-three years of age, showed 

 a total growth of nine to twelve inches in diameter, while at only sixteen years 

 of age the Paradox on a dry, hard sidewalk is over two feet in diameter at four 

 feet from the ground. It is well to bear in mind that walnut trees require a 

 year or two to make a strong tap root and become well established. 



In view of these facts, it is pertinent to ask, what will be the size of Para- 

 dox trees when thirty-three years of age? Will they not be four times as great 

 in diameter at the ordinary Black Walnut at the same age? At Santa Rosa, 

 San Jose, Campbell and other California points, where both varieties are grow- 

 ing side by side, these facts are now self-evident. Touching the high quality of the 

 lumber cut from Paradox logs, the accompanying illustrations tell their own 

 story. Note the compact grain of the wood, the fine gradations of light and 

 dark shadings so essential and pleasing in interior finishing and cabinet work. 

 When to these is coupled unusual strength, durability and other good qualities, 

 we certainly have an ideal high-grade lumber.
