Flowers nearly white. Much cultivated for oil used for varnishing, which is expressed 
from seed. The oil expressed from the nuts of this tree is known as tune oil, or wood oil. 
It is the fastest drying oil known to paint manufacturers, and is imported by the thousand 
gallons from Hankau. The Devartment of Agriculture is experimenting with its culture, as 
the tree grows and bears well in the Southern States (see page 1027).
