stroyed, and such trees may then be set out with as much safety 
as though they had never been affected. This, at all events, is a 
point which any nurseryman can easily ascertain by experiment. 
Mr. Downing recommends the mixing of a shovelful! of ashes 
with the earth in which such trees are set, which may be equally 
as effectual as an immersion of the roots in soap suds. 
AFFECTING THE TRUNK. 
Excavating a round flat cavity under the bark near the root, and then boring a 
cylindrical hole upward in the solid wood: a yellowish or white, footless, 
cylindrical grub, broadest anteriorly, with a brown head and black jaws.

This is one of the worst enemies against which our apple trees 
have to’contend. It is much more common everywhere in our 
country than is generally supposed. The editor of the Ohio Cul¬ 
tivator (vol. x, page 212,) speaks of it as a New England insect, 
which has never been seen as yet, to his knowledge, in Ohio. 
There can be no doubt, however, that it is common in that State, 
for I met with it last autumn in the orchards of Michigan and 
Illinois, and am informed by the editor of the Prairie Farmer 
that it has for many years been found in the neighborhood of 
Chicago. Specimens of the beetle have also been sent me from 
Arkansas; and as this is a native insect, which breeds in the dif¬ 
ferent species of thorn, in the mountain ash, and the shad-bush, 
there is a strong probability that it is as widely spread over our 
country as these trees are. And notwithstanding it has been so 
often noticed in our agricultural and other papers, many of our 
citizens are yet wholly unaware.of its existence, and others who 
are familiar with the published accounts, suppose it occurs only 
in some distant localities, and are wholly unsuspicious that their 
own neighborhoods and their own trees are suffering from it. We 
have reason to believe that in many instances where orchards are 
dwindling and dicing fiom the attacks of this insect, their pro¬ 
prietors suppose there is something in the soil or local situation 
which prevents their fruit trees from being more vigorous and
