APPLE-TRUNK BOHEE ITS EXTENT. 11 



stroyed, and such trees may then be set out with as much safety 

 as though they had ne7*r 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 THUNK. 



Excavating a round flat cavity under the bark near the root, and then boring a 

 cyliudricalTiole 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 om 

 country than is generally supposed. The editor of the Ohio Cul- 

 tivator (vol. X, page 212j) 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 tlw 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 tiom it. We 

 have rfason to believe that in many instances where orchards are 

 dwiodling and dicing fiom the attacks of this insect, their pro- 

 prietors siippo.-e there is soniething in the soil or local situation 

 which prevents'their fruit trees from being more vigorous and
