The only figure that fails to support the above statement is that 
for scald in the box crop, where the average, calculated on the basis 
of all cars showing disease, is no larger for southern offices than for 
" all other offices." 
If the comparison is made by years (Table 16), using only the dis- 
ease index rather than its constituent parts — rots, scald, and other 
diseases — it appears that in only one instance (barrel crop of 1917) 
was the figure for southern offices less than that for all other offices. 
This is the smallest group of cars that appears in the table and is 
of little significance as compared with the barrel-crop inspections for 
1919 and 1920.

The difference is still apparent if a comparison is made (1) of scald 
figures for southern offices, calculated on the basis of cars showing 
scald (Table 17), with other scald figures, similarly calculated for all 
other offices; (2) of disease indices in shipments from States where 
part went to southern and part to other offices of the inspection 
service. (See Table 18 and fig. 4, which give such data for the 
barrel crop of 1920.)
