PEACH BLISTER. 
Y one who is acquainted with Peach trees is 
probably equally well acquainted with the disease of 
the leaves known as ‘ Peach Blister.” This disfigur- 
ing disease of the foliage is not confined to the Peach 
but occurs on Almonds and allied plants, 1s 
rally most common in spring and early summer, and 
makes itself manifest by large leathery red wri " 
blisters on the leaves. A fungus known as 
deformans (so named by Mr. Berkeley) frequently or 
invariably accompanies this red blister ; it grows upon 
the blister of the leaf, generally upon the lower 
surface, but not unfrequently upon the upper side. 
At times the fungus may be sought for in vain, in fact,
