The ravages of this worm may not only be prevented, but 

 they may be defied and counteracted. We may stimulate the 

 growth of a peach-tree so that it will form new bark faster than 

 the wonn can eat it, while its foliage may retain the deep green 

 color of vigorous health, and its fruit be magnificent. This, 

 however, is a dangerous though interesting experiment, the 

 fullness of sap induced in the process exposing the tree to the 

 risk of being winter-killed ; but with a hardy variety, and ujxin 

 a northwest exposm-e, it has been successfully performed, with 

 the worm working imchecked and severely to the height of 

 eighteen inches aljove the ground. Any one may repeat it 

 who will plant a peach-tree upon a slope in such an exposure, 

 and set a hog-pen six feet above it.

lIpK beetle, magnified. 



A very small beetle, of a deep brown color, -nith paler legs. 

 Wing covers with obscurely-punctm-ed rows. 



The worm is minute. It eats into the smaller limbs of the 

 pear-tree, and, reaching the pith, works from that centi'e until 

 a narrow section of the wood is eaten out to the bark, forming 

 a circular cell, and the limb above the point of the injm-y droops 

 and dies suddenly. 



Remedy : cut off the limb and bm-n it the moment you per- 

 ceive the leaves to droop.
