122 PHILIPPINE RESINS, GUMS, AND OILS 
Aguilar,* who also has made a study of the Philippine oils, 
says that lumbang oil is similar to linseed oil in its properties 
as a paint vehicle, and that, like linseed, it has certain disadvan- 
tages for use in red-lead paints. Bagilumbang oil cannot be used 
as a paint vehicle, especially with red lead, as it dries into a 
paste. Aguilar found that a mixture of the two oils, containing 
25 to 50 per cent of lumbang oil makes a good paint vehicle for 
red lead. The Aleurites oil so far produced in the Philippines 
is almost entirely the product of Alewrites molwecana, which is 
fairly abundant in a wild state in many parts of the Philippines, 
and is also planted. Alewrites trisperma is reported from many 
localities, but is probably not so abundant. Both species can be ¢ 
grown readily in plantations. 
The Bureau of Forestry is using large numbers of both species 
in its reforestation projects and is also distributing seed and 
encouraging other people to plant these species. It is safe to 
say that at the present time the yearly planting of these species 
amounts to between 400,000 and 500,000 trees. From these 
figures it would seem reasonable to predict that in the near 
future large quantities of Aleuwrites oil will be available in the 
Philippines. During the year 1918, 184,428 kilograms of Aleu- 
rites moluccana oil valued at 129,838 pesos were exported from 
the Philippines. 
That there would be a market for considerable quantities of « 
Aleurites moluccana (lumbang) oil is shown by the fact that 
one American concern, which has experimented with this oil, 
has inquired as to the possibility of obtaining 4,000 tons per 
month.

The oil of Alewrites moluccana is known in the Philippines 
as lumbang oil. This species is distributed through Polynesia, 
the Malayan region, and the Hawaiian Islands. In Hawaii the 
oil is called kukui or candle-nut oil. The latter name is also 
used in other parts of the world. According to Wilcox and 
Thompson + the Hawaiians strung the nuts on sticks and used
