124 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 Aleurites moluccana, which is 

 fairly abundant in a wild state in many parts of the Philippines, 

 and is also planted. Aleurites 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 Alem^ites 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 moluccaria (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.

LUMBANG OIL. 



The oil of Aleurites 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 f the Hawaiians strung the nuts on sticks and used
