bark-louse, called the mealy-hug, is naturalized in our 

 green-houses, where it does much injury. It is the 

 Coccus Adonidum, and is at once distinguished from 

 the former by the white dust with which it is covered, 

 and by the cottony substance with which it envelopes 

 its eggs. Bark-Hce of every kind may be destroyed 

 by the application of a ley of ashes, or a solution of 

 potash. 



An infinite number of noxious insects invade our 

 fruit-bearing trees and shrubs. It will be possible 

 to notice but a few of them. Passing by, therefore, 

 the minute bugs which revel upon the juices of the 

 raspberry and strawberry, and make themselves known 

 only by their abominable odor when crushed ; — the 

 ants, wasps, and flies, which unite to rob us of our ripe 

 grapes, cherries, peaches, and pears ; — the saw-fly, an 

 imported insect, whose gregarious larvae devour the 

 leaves of the gooseberry ; — the JEgeria,* also a for- 

 eigner, which, in the caterpillar state, perforates the 

 stems of the currant-bush; — the muscle-shaped bark- 

 louse which adheres to the Hmbs, and the moth whose 

 caterpillar lives in the fruit, of the apple-tree, both 

 apparently introduced from abroad ; — passing by 

 these, and a host besides, we must advert only to 

 some of the insects, whose threatened, repeated, or 

 extensive ravages render them peculiarly obnoxious 

 to the lover of good fruit. 



From a period of high antiquity, the culture of the 

 grape has occupied the attention of civihzed man. In 

 regions favorable to its growth, it forms a very con-
