bagilumbang. Although the extraction of oil from bagilumbang 

 nuts alone might not be profitable with the present small supply, 

 it would probably become so if carried on in connection with the 

 extraction of lumbang oil. 



The fertilizing value of the cake «)f Aleiirites tnsperma com- 

 pares favorably with that of Aleurites moluccana, as will be seen 

 from Table 22, taken from Aguilai.

Planting experiments carried on by the Division of Investiga- 

 tion, Bureau of Forestry, at Los Bafios, showed a germination 

 of 98 per cent, germination taking place in nineteen days. At 

 the end of the first year the plants had an average height of 

 54 centimeters. 



This species, like Aleurites moluccana, was hardy and grew 

 rapidly. The average rates of growth of large numbers of trees 

 are given in Table 23.

Aleurites trisperma is a tree 10 to 15 meters or more in height. 

 It does not have hairs except on the inflorescences. The fruit 

 is 5 to 6 centimeters in diameter, somewhat rounded and angled, 

 opens later along the angles, and usually has three cells, each of 

 which contains a single seed. The seed is somewhat circular, 

 flattened, rather smooth, but with numerous small ridges. It 

 has a hard, brittle shell about 0.5 millimeter thick. This con- 

 tains a white, oily, fleshy kernel consisting of a very thin em- 

 bryo surrounded by a large endosperm. This in turn is covered
