AMERICAN FOREST TREES 



eight or ten inches in diameter; but trees occasionally are sixty feet high and eighteen 

 inches through. The leaves are small, measuring from six to nine inches in length, 

 with from nine to seventeen leaflets. Nuts are about half the size of eastern black 

 walnuts. The kernel is edible. The wood is heavier than black walnut, and some- 

 what lighter in color. Otherwise the two woods are much alike, except in strength 

 and stiffness. In these the California wood is inferior. It has not been reported for 

 any use, but it is suitable for a number of purposes, provided logs of sufficient size 

 could be had. The trunk, in addition to being small, is usually short. The tree is 

 intolerant of shade, and is not often found in forests. It grows rapidly and will 

 attain a diameter of fifteen inches in twenty years or less; but it apparently does not 

 live long. Its principal usefulness in California is as a shade tree, and as a stock in 

 nurseries on which to graft English walnut.
