THE ORCHARD 



ing " wormy apples." It is estimated that this worm has 

 caused over $7,000,000 damage each year in the states of 

 Nebraska, Illinois and New York alone. The codling 

 moth can be controlled pretty well by spraying the trees 

 soon after the flowering period with water containing 

 Paris green stirred in it, at the rate of one pound to two 

 hundred gallons. 



The woodpecker finds the worm hidden in his silken 

 cocoon under the scales of the bark of the apple tree. 

 This bird should not be killed. He is doing a good work 

 in destroying the worms that would otherwise spoil many 

 apples. 



THE PLUM AND CHERRY. 



The Plum and Cherry are favorite fruits which can be 

 grown over much of the United States and parts of 

 Canada. They grow on small trees that begin to bear 

 when they are three or four years old. The trees 



are planted in the orchard 

 when they are about two 

 years old, and are set about 

 sixteen feet apart each 

 way. 



The Curculio An insect 

 called the curculio troubles 

 the fruit by laying an egg in 

 it. The egg hatches into a 

 maggot that lives on the 

 fruit until full grown. It is 

 usually this maggot that causes plums to drop before 

 they are ripe, and that causes " wormy " cherries. The
