SHIPMENT OF RED RASPBERRIES. 25 
The results of this work, while decidedly beneficial in most re- 
spects, emphasize str ikingly, as in the case of many other fruits used 
in similar tests, that precooling can never be depended upon to ac- 
complish nearly as much as careful handling. While precooling 
proved decidedly beneficial, it did not in any measure. overcome the 
bad effects of rough, careless, and improper handling. The most 
noticeable. feature of the precooling was the improved appearance 
of the precooled berries, which were decidedly brighter and fresher 
than those held without precooling. 
PRECOOLING EXPERIMENTS IN THE SEASON OF 1911. 
The inspections were made in the same way as those described for 
the careful-handling investigations. Table 5 and Figure 21 give the 
results of the precooling work during the season of 1911.

per cent of decay, respectively, at the end of the 8-day period. The 
after-withdrawal inspections are consistent with the withdrawal 
results. The ratio of percentages of decay is much the same at the 
end of the 4-day period (9.5 per cent of decay in the precooled and 
16.5 per cent of decay in the regular iced) and at.the end of the 
8-day period (86 per cent of decay in the precooled and 45.1 per
