tree, but it will grow in some parts of California exceedingly well. A 

 tree near Niles, in Alameda County, about fifteen years old, stood about 

 thirty feet high, with a noble sweep of branches. This tree grows

Walnut. Both the eastern and native black walnuts make grand 

 shade trees over a large and varied area in California, from the intense 

 dry heat of the interior to the cool and moist conditions of the north- 

 ern coast line. Some prefer the eastern black walnut because it is 

 inclined to drop all its leaves at once instead of being so slow about 

 going to sleep as the native species is thus scattering litter for a long 

 time and keeping the ground wet by partially excluding winter sun- 

 shine.
