various machines available should be made befoi e definite reconi 
mendations in favour of anyone are made.” The essential point if 
the kernels are to be exported is that these should not be injured in 
the husking. 
It remains to be considered whether it would be financially more 
advantageous to ship the dried kernels or to express the oil here and 
export this only. If the latter course were to be adopted, there 
would of course be less danger of losses through fermentation of the 
husks. On the other hand there would probably be less difficulty m 
marketing the kernels than the oil. 
Agriculturally, it would be preferable to retain the oil cake in 
the country where it could be directly or indirectly returned to the 
soil. Whether the cake can be used as a'cattle food remains to be 
proved. It might be found to possess deleterious or even poisonous 
effects on cattle. In any case it could be used as a manure, con- 
taining as it does a fair percentage of nitrogen. 
Weight of Seeds from Tapped or Untapped Trees. 
As mentioned above Messrs. Macmillan and Petch state that 
they find a large difference between the weight of seed from 
tapped and untapped trees, the latter being considerably 
heavier. The figures thev give are 9.1 lbs. against 7.8 lbs. per 1,000 
seeds, a difference of 1.3 lbs. or 16% per cent, on the weight of seeds 
from tapped trees. 
To see whether the difference were an actual one and if so what 
would it would amount to here, and extensive series of weighings 
was carried out by Mr. Spring. Trees of the same age in the Ex- 
perimental Plantation and the Public Gardens, Kuala Lumpur, gave 
an excellent opportunity for comparison. The following are the 
actual results : —
