in Georgia are the Carman, Early Crawford and others. Ob- 
servations on the question of varietal resistance need to be 
extended. 
The average annual loss to the peach-growers of this country 
because of brown-rot is placed at $5,000,000. For the year 
1900 Georgia growers are said to have lost from $500,000 to 
$700,000, and the average annual loss is estimated to be not 
less than 40 per 
cent. Again, in 
1909 the loss of 
peaches due to 
brown-rot in 
Georgia, with only 
one-third of an 
average crop, is 
said to have 
reached $1,000,- 
000. Almost a 
total loss of the 
peach-crop is re- 
ported from Ala- 
bama in 1897, and 
similar losses occur 
in other southern 
states. While in the northern states and in Canada peach- 
growers do not experience any such calamities, yet these 
regions are by no means exempt from the disease, and in 
some years the outbreak is severe. The loss from this disease 
is not limited to the fruit-growers, but is felt by the 
transportation companies, the commission men and the con- 
sumers. A shipment of fruit which shows great promise as 
it leaves the orchard may reach the market in a worthless 
condition. The disease is destructive in one or more of the 
following ways: (1) blossoms may be blighted, destroying
