Although the oil cake apparently has a high food value it can- 
not, according to Wilcox and Thompson, be used as cattle food 
because it has a poisonous effect upon stock. It is a matter of 
common knowledge that the kernels, either fresh or old, are 
strongly purgative. The cake left after the oil has been ex- 
tracted from the kernel is used as a fertilizer, chiefly by the 
Chinese betel-pepper growers. 
Lumbang has been very successfully grown by the Division 
of Investigation, Bureau of Forestry, at Los Banos. The planting 
of this species was begun by Forester H. M. Curran. Table 20 « 
gives average rates of growth of large numbers of these trees. 
For the last few years the trees in the plantations have been 
rather crowded, and the best trees have made considerably faster 
rates of growth than the average indicated in the table. The 
smaller trees should be removed so as to leave more space for 
the larger ones. The trees which will be left permanently in 
the plantation have, therefore, shown a faster rate of growth 
than that given in the table.
