spirit added to it. These may be fastened among the branches of the 



trees with cord or pieces of wire. 



The insects, being attracted 1>\ 



the smell of the compound, they 



are lured into the bottle and 



drowned, and thus the mischief 



they were about to perpetrate 



is nipped in the bud. Later in 



the season the wormy fruit should 



be carefully gathered, and either 



dipped in boiling water to destroy 



the grubs, or fed to hogs. Fig.

of the insect : a section of apple 



attacked, b point at which the 



egg was laid and at which the 



young worm entered, e the full grown worm, h its head and portion ot 



body magnified, i the cocoon which it spins, d the chrysalis enclosed in 



the cocoon, /the perfect insect as it appears when at rest, £ the same with 



its wings expanded. 



Borers. June is the month for borers of all kinds, so lookout for your 

 apple trees ; prevention in this instance is far better than cure, and by 

 taking a little pains now the entrance of the borer may be prevented. Soft 

 soap, reduced with water to the consistence of thick paint, and applied 

 copiously over the trunk, and a short distance up the main branches of the 

 tree, will prevent the beetles from depositing their eggs on such at all, and 

 besides will have the effect of cleansing the bark from many other animal 

 and vegetable parasites.
