Decay, averaging 3.8 percent per carlot showing decay, was found 

 in 586 carlots, or 64 percent of those inspected. Distribution of decay 

 by types was as follows:

All strawberry inspections are summarized in table 11 



Decay 



per carlot inspected ranged from 0.9 to 5.7 percent, with an average of 

 2.4 percent. Gray mold rot accounted for about two-thirds of the 

 decay, and rhizopus rot for most of the rest. Leather rot was reported 

 every year but one and from all three States. Far greater spoilage 

 occurred in shipments from Arkansas than in those from either Louisi- 

 ana or Florida. The least decay occurred in shipments from Florida.

Tangerines 



Tangerines were inspected only dining 1936-38. Approximately 

 4.200 carlots were unloaded, chiefly from November through April. 

 All but 1 carlot originated in Florida. Rail shipments comprised 24 

 percent of all unloads; the rest came by boat. 



Inspections were made on 67 carlots, or approximately 7 percent of 

 all rail unloads. Distribution of decay within them was as follows:
