BULLETIN 331, U. S. DEPARTMENT OF AGRICULTURE. 
For instance, during 1913, in the carefully handled fruit in the 15-day 
withdrawal lot, the immediately precooled fruit showed 1.1 per 
cent of decay, as against 6 per cent in the fruit delayed prior to cool- 
ing. At the end of a 4-day holding period the fruit immediately 
precooled showed 3.8 per cent of decay, as against 12.8 per cent in 
the delayed precooled fruit. The data are equally consistent through- 
out and emphasize again the absolute necessity of handling the fruit 
from the tree to the car or the precooling plant with the utmost 
rapidity consistent with care in all operations.

RELATION OF BROWN-ROT TO FRESH-PRUNE SHIPMENT. 
During the seasons of both 1911 and 1913, and especially during 
the latter season, brown-rot was an important factor in determining 
the condition of prunes in transit and on the market. A great deal
