 of the branches. Finally the tree dies. 



Winter injury to the bark of the trunk or main limbs, mechanical in-

 of moisture or nitrogen in the soil may discolor the foliage and cause 

 premature ripening of fruit and should not be mistaken for "Yellows." 



PEAR BLIGHT. 



On left: Pear blight in a bearing tree. The blight should not have beeD permitted to spread as far 

 as it has in this tree. On right: Pear blight in a young tree. 



Little Peach. In "Little Peach," characteristic symptoms are : the 

 leaves of a part or the whole of the tree have a bunched appearance, and 

 are shorter, and broader than normal leaves. They are usually yellowish- 

 green in color with the veins appearing dilated and darker than the in- 

 tervening tissue. The fruit is usually under size and ripens from a week 

 to two weeks late. The flesh is more or less stringy, watery and very 

 insipid while the pit is usually very small. One or all symptoms may 

 be present and unless they can be positively attributed to some other 

 cause, the tree should be condemned, pulled out and burned.
