Early Ked Margaret, Sabadka, Winesap, and Yakor 

 which showed rust last year, escaped this, and, in addi- 

 tion to those affected last year, there are thirty-four 

 more varieties affected this season. A greater number 

 of the Hungarian varieties were affected this year than 

 last year. Resistant varieties have for the past few sea- 

 sons been giving a good deal of promise, but this season 

 so many more varieties were affected than usual, that 

 it is probable we have no varieties in our orchard that 

 are perfectly resistant to the disease. 



Spraj/'uifj to Prevent Rust. — To determine if very 

 thorough spraying with Bordeaux mixture would have 

 any effect upon the rust, one tree of each variety was se- 

 lected and kept very carefully sprayed from early spring 

 until late in the fall. The Bordeaux mixture was used 

 at the rate of six pounds of copper sulphate and six 

 pounds fresh lime to fifty gallons of waiter. 



The varieties selected for this spraying experiment 

 were affected during the season of 1900 as follows : 



Carter's Blue, slightly. 



Cooper's Red, moderately.
