From this table it will be seen that 
there was 0.79 per cent, more and 0.37 
per cent, less of acid in the fruit from the 
south side of the tree than in the fruit 
from the north side of the tree. Conse¬ 
quently it is seen that the utmost care 
must be exercised in order to get an av¬ 
erage sample of the oranges to be tested. 
The total sugar as invert sugar, the total 
acid, as crystallized citric acid, the ratio 
of the total acid to the total sugar, and 
other determinations were made. 
A careful study of the climatological 
data for temperature and rainfall for the 
orange section was made, but no conclu¬ 
sions could be drawn from one season on¬ 
ly. The study began in October after 
a very heavy rainfall for the orange sec¬ 
tion for September^ over 11 inches, with 
decreasing amounts for each succeeding 
month. The fall and winter had been 
unusually warm, with the warmest Jan¬ 
uary since 1892. It would take analyses 
from numerous localities for several sea¬ 
sons to draw conclusions of any value 
in regard to the influence of seasonal 
variations on the composition of the or¬ 
ange. An attempt was made to corre¬ 
late the irregular decrease of the acid 
content of the orange with the rainfall, 
but without success. The observations 
on the location, in the extreme northern 
part or the extreme southern part of the 
orange section, did not show that the 
difference in climate between them had 
any effect as to the date of maturing. 
The peculiarity of the individual varie¬ 
ties of the orange is the only influence 
that was noted to have an effect on the 
date of maturity. 
The oranges of which this study was 
made were as follows:
