Table XVIII and figure 21 give the average percentages of decay of oranges from 
two packing houses in the same locality working on practically the same kind of fruit. 
The type of work in house No. 1 was good, but that in house No. 2 was rather poor. 
These shipments were made at the same time, and the results of carefully handled 
lots prepared by the bureau workers from the same houses are given for comparison.

Fig. 20.— Diagram illustrating the percentage of blue-mold decay of oranges on arrival in Washington

It will be noticed that the commercial shipment from house No. 1 gave practically 
as favorable returns as the specially prepared shipments of the bureau workers, the 
difference being only 2 per cent, both series from this house having less than the 
commercial allowance of 3 per cent decay on arrival. The commercial shipments 
from house No. 2, where observation showed the handling to be rather careless, had 
developed 21.3 per cent of decay on arrival at Washington, while the fruit handled 
by the bureau workers at the same time and shipped under identical conditions 
showed 0.3 per cent of decay. After three weeks the commercial shipments from 
house No. 1 averaged 5.7 per cent of decay, and those from house No. 2 showed 59.5 
per cent, as against 2.5 per cent and 0.7 per cent, respectively, for the carefully 
handled fruit.
