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
