treatment was given on June 10. A few of the characteristic spots 

 of anthracnose were now noticed for the first time on the new 

 canes in the untreated rows, showing that the disease was spread- 

 ing very slowly. June 24 a fifth treatment was made. It was 

 again noted that the disease had spread but little on the un- 

 sprayed plants and practically none could be found on the treated 

 canes. As soon as the fruiting season was over the old canes 

 were removed from all the rows, and a riith spraying was given 

 August 15. 



The yield for the season of 1895 is given below in Table III.

Season of 1895. 



Again the record of yields fails to show any material gain 

 resulting from the treatment. The cause of the slight increase 

 in yield of the rows that were sprayed once before the leaf buds 

 opened with iron sulphate would be difficult to explain. 



The plantation was visited on Nov. 19, when it was found that 

 the canes in all of the rows that had been sprayed were practi- 

 cally free from disease, and since the removal of the old canes in 

 August but comparatively little was to be found on the unsprayed 

 rows.
