88 THE NUKSERY AND THE ORCHARD. 



is left to mature on a well grown tree. Many methods of 

 protection against the enemy have been tried with par- 

 tial success, among them, smoking with the fumes of coal 

 tar, syringing with Paris green or other poisons, dusting 

 with sulphur and lime and various ways of entrapping, 

 but perhaps the best results are obtained by jarring the 

 trees and destroying the insects and stung fruit that fall. 

 By giving a sharp, quick blow with a mallet on the stub 

 of a limb sawed off, o^ a peg inserted in the tree to pre- 

 vent bruising, many of the insects will fall", and can be 

 caught on a sheet spread under the tree for the purpose. 

 The jarring is commonly done early in the morning or 

 just before night. When hogs are turned under the trees 

 while the fruit is dropping, they consume large quanti- 

 ties of the grubs, and thus prevent so rapid multiplica- 

 tion, but they afford no immediate protection. Trees 

 planted near the house, where they will be constantly 

 tramped around, are comparatively free from attacks of 

 this troublesome insect. To succeed in raising large 

 crops of fine plums, war must be declared very early 

 against the curculio, and waged unremittingly until th& 

 fruit is gathered. 



If you have never seen this insect, quietly approach 

 one of your plum or nectarine trees early some morning 

 in May, give the tree a quick rap, and you will be likely 

 to enjoy the pleasure. 



THE PEACH TREE BORER. 



This troublesome insect attacks the peach, nectarine 

 and apricot, and if left unmolested will in a few years 

 become very destructive. Large orchards fall a prey to
