 This is a fungous disease which attacks the fruit of the peach, 

 apricot, cherry, and plum, and als'o the leaves and twigs ol the 

 peach. Kcmaining- dormant upon the latter during the winter sea- 

 son, it is capable of being- transmitted with diseasetl peach stock in 

 spring-. (Jn the young twig-s it produces purple blotches, in which 

 the bark sometimes splits, as does also the skin of the fruit when 

 affected by the same disease. 



It checks the growth of young- trees, but is mainly injurious 

 to the orchardist by its subsequent infection of the fruit when the 

 trees begin to bear. Peach-trees exhibiting this disease should not 

 be sent out by the nurseryman, but should be destroyed as harmful 

 to the nursery trade.
