COMPOSITION AND MATURITY OF CANTALOUPES. 21 
an increase because of a slight concentration of juice, these figures 
indicate that a decrease in sucrose occurred after the melons were 
removed from the refrigerator car, at the relatively high room temper- 
ature that prevailed at the time. It is believed, however, that this 
loss was not much greater than 1 per cent of sucrose. 
Further evidence on the effect of storage on composition was found. 
Two crates of half-slip melons were gathered from the field at Brawley, 
expressed to Los Angeles, and placed in cold storage at a temperature 
of 8° C. At regular intervals samples were removed and analyzed, 
counting the time of storage from the date of arrival in Los Angeles. 
No significant changes were found during 10 or 12 days, any differ- 
ences being within the sampling error. All these samples were ana- 
lyzed immediately on removal from the refrigerator. The results, 
together with those in Table 11, support the conclusion that at such 
eee the changes in composition of the constituents measured 
are slight. 
The effect of storage upon the composition of the juice of melons 
stored at Porterville and at Turlock in 1920 is shown in Table 12. 
Only full slips were used for the comparison, as they are more uniform 
in composition than other types. 
The Porterville melons were stored in an ice house at temperatures 
from 2° to 5° C. for 10 days, after which they were shipped by express 
to Turlock for analysis. Usually less than 24 hours elapsed from the 
time of removal from the refrigerator until the time of analysis. 
The Turlock melons after storage in, an ice house at from 2° to 5° C. 
for 10 days were shipped by express to Los Angeles, the transit period 
being about 48 hours. They were then held in cold storage from 
4 to 5 days and analyzed. 
During the analytical work, some of the melons were badly broken 
down; that is, the flesh became very soft and watery. In some cases 
a distinctly bad odor developed.
