BARREL CROP: DISEASE BY STATES. 
Id, the four States represented by more than 75 cars — New York, 
Virginia, West Virginia, and Michigan, total 1,051 cars — the aver- 
age percentage of rot (Table 12) was 8.7, the average of the disease 
indices 15.7. In all other States and in Canada, with a total of 497 
cars, the average for rots was 14.4 per cent; for disease indices, 19.2.

The significance of these figures is not clear. They may have no 
significance at all, but on the other hand they may mean that in States 
where the commercial crop is large those methods of growing, handling, 
and storage which prevent loss are better understood and more gen- 
erally used than in the States where the commercial crop is small. 
BOX AND BARREL CROP: DISEASE BY INSPECTION OFFICES. 
If the figures for southern offices — Atlanta, Baltimore, Fort 
Worth, Houston, Jacksonville, Louisville, Memphis, New Orleans, 
Oklahoma City, and Washington, D. C. — are compared, in both 
barrel and box crop, with figures for all other offices (see Tables 13 
and 14) it is found that the former are, on the average (Table 15), 
larger than the latter. That is, there- was greater loss from disease 
in cars shipped to southern markets than in cars shipped to other 
markets of the country.
