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 (36 per cent of decay in the precooled and 45.1 per 

 cent of decay in the nonprecooled). These data, while emphasizing 

 the beneficial effects of precooling, bring out most strongly the im- 

 portance of careful handling. 



PRECOOLING EXPERIMENTS IN THE SEASON OF 1912. 



During the season of 1912 the precooling investigations were con- 

 tinued, and carefully handled as well as commercially handled ber- 

 ries were used. The fruit was shipped to Grand Forks, N. Dak., 

 as in the case of the handling investigations previously noted. Un-

fortunately, owing to market conditions a number of precooled and 

 check cars were diverted and did not reach the inspection point. 

 The data, while therefore not as comprehensive as desirable, are 

 nevertheless consistent with the results of the 1911 season and are 

 considered sufficiently conclusive to warrant final deductions being 

 made. 



As in the season of 1911, more beneficial results were obtained from 

 careful handling than from precooling alone. The results, however, 

 bring out clearly the fact that precooling with proper handling is 

 of great service and value in the preservation of fruits like red 

 raspberries in maximum good condition while in transit. Table VI 

 and figure 22 show the results of the Carefully handled precooled 

 and nonprecooled shipments.
