The record of yields tends to prove nothing except that the 

 treatment seriously injured the fruiting canes in the treated rows. 

 It should be borne in mind, however, that this injury was due to 

 the fact that the Bordeaux mixture used in a single application 

 was improperly made. The almost entire absence of anthracnose 

 on the treated rows as compared to the considerable amount found 

 on the unsprayed rows at the close of the season goes to show that 

 the treatment was effective. 



Experiments in 1895. 



The plantation was given the same treatment throughout the 

 season of 1895. 



Dates of spraying. — The first spraying, when the diflerent solu- 

 tions were applied, was given on April 2G, just as the leaf buds 

 began to swell. The second treatment was begun May 11, but 

 on account of rain it was not completed until May 13. At this 

 time the new canes had just begun to grow. On May 24, a third 

 spraying was given, when the largest of the new canes were

 tions had been seriously injured by the application. A fourth
