 times ascends to an elevation of three thousand feet above the ocean level/ 



The wood of Juglans Californica is heavy, hard, and rather coarse-grained, with a satiny surface 

 susceptible of receiving a good polish. It contains numerous regularly distributed open ducts and thin 

 obsciu^e medullary rays, and is dark brown, and often handsomely veined and mottled, with thick pale 

 sapwood, composed of eight or ten layers of annual growth. The specific gravity of the absolutely dry 

 wood is 0.6266, a cubic foot weighing 39.04 pounds. 



Juglans CaVfornica appears to have been first noticed by Dr. C. C. Parry,^ who found it in 1850 

 north of Los Angeles.^ 



Juglans Californica is often cultivated in California as a shade-tree, and is sometimes used there 

 as a stock upon which to graft different varieties of Juglans regia. Introduced into Europe through 

 the Arnold Arboretum, it flowered in the spring of 1889 in the garden of the Villa Thuret at Antibes 

 in southern France.
