peach does not fully merit them? ha 
Whether the system of shortening-in and careful culture will 
prevent the breaking out of the Yellows when constitutionally 
latent in the tree, we will not yet undertake to say. A few more 
experiments will prove this.’ In slight cases of the disease we 
believe that it may. Of one thing, however, we are certain: it 
has hitherto failed entirely to reclaim trees in which the malady - 
had once broken out. Neither do we know of any. well at- 
tested case of its cure, after this stage, by any means what- 
ever.* Such cases have indeed been reported to us, and pub- 
lished in the journals, but, when investigated, they have 
pen to have been trees suffering by the effects of the borer 
only. 
A planter of peach trees must, even with care, expect to see 
a few cases of Yellows occasionally appear. The malady is 
too widely extended to be immediately vanquished. Occasion- 
ally, trees having the constitutional taint will show themselves 
where least suspected; but when the peach is once properly 
enltivated, these will every day become more rare until the ori- 
ginal health and longevity of this fruit tree is again established. 
Taz Curt is the name commonly given to a malady which 
vften attacks the leaves of the peach tree. It usually appears 
m the month of May or June. The leaves curl up, become 
thickened and swollen, with hollows on the under, and reddish 
swellings on the upper side, and finally, after two or three 
weeks, fall off. They are then succeeded by a new and healthy 
trop of foliage. This malady is caused by the punctures of 
very minute aphides, or plant lice, (Aphis Persice?) which at- 
tack the under side of the leaves. Although it does not appear 
materially to injure either the tree or the crop, yet it greatly 
disfigures it for a time. In orchards, perhaps few persons will 
fodbis themselves to destroy the insect, but in gardens it is 
much better to do so. A mixture of whale-oil soap, or strong 
soft soap and water, with some tobacco stems boiled in it, and 
the whole applied to the branches from below with a syringe 
or garden engine, will soon rid the tree of the insects for one 
or more years. , It. should be done when the leaves are a third 
grown, and will seldom need repeating the same season.
