274 THE STONE FRUITS 



borers are dug out, which should be done sometime in June, 

 a small mound of earth should be pulled up around the trunk 

 to a height of 8 to 10 inches. 



Many washes and disinfectants have been used from time 

 to time, but all of these have to be handled with some care, 

 and they are not very satisfactory. 



Peach Louse. — The peach louse sometimes becomes serious.

The trees should be examined carefully every spring and 

 fall for the borer, which should be dug out whenever it is 

 found. Where the yellows or the little peach is present 

 destroy the tree as soon as the disease is discovered. 



PLUM. 



The plum is a very old fruit. The native species ha^-e been 

 found growing in this country for many years. As early as 

 1524 foreign explorers of America tell of plums which were 

 found growing wild in this country in the \'icinity of New 

 York. A little later, in 1539, another explorer describes the 

 plum growing abundantly in the region of Florida. From
