8 PROCESSING OF JAPANESE PERSIMMONS. 
the dealer supplying the gas. If no reducing valve is used, sudden 
stoppages will usually occur during the outflow due to the choking 
of the orifice in the needle valve with solid carbon dioxid. Such 
stoppage is usually followed by a sudden rush of gas, and very close 
watching is necessary if annoying accidents are to be avoided. 
Processing experiments were conducted at the nurseries of the 
Griffing Bros. Co. at Macclenny, and at the Glen St. Mary nurseries 
at Glen St. Mary, using in all cases fruit freshly picked from the trees. 
Two of the iron tanks were used at each locality. At the outset it 
was supposed that the control of the humidity was an important 
feature in processing, and so the treatment of the persimmons was 
conducted in one of the tanks at each locality, with no attempt made 
to lessen the very humid conditions which occur during processing, 
while in the other the humidity was somewhat lessened by dis- 
tributing about 50 pounds of dry starch among the persimmons. 
Perceptible differences in the amounts of moisture which collected at 
the top of the boxes during the processing period were noticeable in 
the experiments at each locality, but as no injury traceable to exces- 
sive humidity was observed at any time, the measures taken to lessen 
it are without importance. 
The experiments in Florida were started September 19 and com- 
pleted September 27. During this period the diurnal changes in 
temperature were quite uniform, as shown by recording thermome- 
ters operated at each locality. The experiments at Macclenny were 
conducted in a carriage shed, the doors of which were usually kept 
closed. Here the temperature ranged from 70° to 86° F., with an 
average of about 77° F. At Glen St. Mary experinents were carried 
on in an open shed, and the temperature variation was from 73° to 
99° F., with an average of about 80° F. 
The number of fruits used in process and in check lots and the 
time required in processing are shown in Table I.
