PESTS OF ORCHARD AND FRUIT GARDEN. 



Fruit-growers will find indicated in the following pages most of the 

 pests which are likely to trouble them in their occupation. The 

 arrangement is rather an artificial one, but it appeared to be best suited to 

 the wants of practical men. Orchard trees will occupy the first portion, 

 whilst the latter will be assigned to bushy and herbaceous plants with 

 marketable fruits. Anomalies may be sometimes anticipated, as, for 

 instance, placing Melons with Gourds and Cucumbers in the kitchen 

 garden, and Tomatos in juxtaposition with Potatos. The Grape Vine 

 and Pineapple, and similar tropical fruits, will have to be dealt with by 

 themselves.
