Throughout the time the fruit is receiving the treatment, air with 
100-percent humidity is forced into and drawn from the rooms. The 
heat and humidity are obtained by injecting steam into the air- 
conditioning unit. 
Owing to the reduction in the number of citrus plantings found 
infested during the year, only about 20 percent as much fruit was 
sterilized as was treated in the preceding season. 
Table 2 lists the amount of fruit sterilized by the two approved 
methods in the fiscal years 1939 and 1940.
