the oil content of kernels due to storage, a sample of fresh kernels 
was secured and divided into two portions. The first portion 
was expressed immediately and gave an oil with an acidity of 
0.55. The second portion was stored in a cool, open, dry place 
for a month, when the oil was expressed, and found to have an 
acidity of 5.32. The fertilizing value of the cake from the kernels 
as well as that of cake obtained from crushed nuts are shown in 
Table IV.

LUMBANG BANUCALAG (ALEURITES TRISPERMA) 
Baguilumbang, balucalad (Laguna) ; banucalag, lumbang banucalag, 
lumbang gubat (Cavite) ; balucanag (Batangas) ; lumbang (Oriental Ne- 
gros, Camarines). Baguilumbang is the name officially adopted by the 
Bureau of Forestry. 
The fruit is 5 to 6 centimeters in diameter, somewhat rounded 
and obscurely angled, usually 3-celled, the cells 1-seeded, tardily 
dehiscent. The seed is somewhat ellipsoid, slightly fiattened, 
brown, rather smooth, and has a rather brittle shell about 0.5 
millimeter thick. This contains a white, oily, fieshy kernel, con- 
sisting of a very thin embryo surrounded by a large endosperm. 
This in turn is covered by a thin, white, papery seed coat. When 
dry the kernel with the thin seed coat shrinks slightly away from 
the shell so that the shell and the kernel are easily separated. 
The close similarity between Chinese wood oil and lumbang 
banucalag oil " and the important place Chinese wood oil is now 
occupying in the paint industry of the world,® clearly show the 
industrial possibilities of banucalag oil. 
The kernel of lumbang banucalag nuts is not so difficult to 
separate from the shell as is that of lumbang bato. When the
