This work, performed as it was on a large scale, agrees rather more 
closely with the results obtained from the series of ten nuts each than was 
to be expected. Here, again, it may be observed that the proportion of 
husk from the seashore nuts is considerably higher than it is from those 
from the interior, while the total amount of water is correspondingly less, 
so that nuts from the two localities yield practically the same amount of 
copra and oil. 
While weighing out 1,000 nuts from the seashore trees it was found 
that 55 of them, or 5.5 per cent, were in such a bad condition as to be 
unfit for making copra, and fresh nuts had to be substituted. Out of the 
same number from the interior only 15 were spoiled. The cause of this 
difference is probably found in the fact that the nuts from trees near the 
sea fall upon harder ground and are therefore more apt to become bruised 
and injured, and it is very possible that the inferior yield of sun-dried 
as compared with kiln-dried copra, in the case of the seashore nuts, 1s 
due to this. Given perfectly sound coconuts, the two methods of drying 
should produce equal amounts of copra, but a green nut, or one which 
has begun to decay, would undoubtedly be more subject to the attacks of 
mold, bacteria, and insects during the comparatively long alternate 
heating and cooling incident to the sun-drying process than if it were 
dried quickly at a higher temperature. 
The figures obtained in this last series on a commercial basis establish, 
even more firmly than do the results of analyses alone, the fact that there 
is practically no difference in quality between the nuts gathered along 
the seashore and those from farther inland. They should also be of some 
value as representing the average yield in copra and oil from nuts pro- 
duced in the southern parts of the Islands. 
NUTS FROM DAVAO. 
The following analyses were made of ripe coconuts, collected near 
Davao, about 1 mile inland from the sea. In this region two varieties of 
trees have been noticed, one producing large nuts rather pointed in shape, 
the other bearing a smaller, rounder fruit. 
Series XIII consists of ten of the small nuts, Series XIV of the large 
variety. On examining these figures it will be noticed that Series XIII 
shows very much the same proportion of its various constituents, as well 
as the total of oil, as the average lot of ripe nuts from San Ramon. 
Series XIV excels in total weight of oil simply because it is made up 
of larger nuts. The percentage of oil in the nut, free from-husk, is the 
same in both series. ‘The nuts in these two series were fairly uniform in 
composition, with the exception of No. 7 in Series XIV, which had a 
total weight of only 92 grams of oil, less than one-half of the average 
amount.
