Subject: — Orchard Insect Pests and Modern Methods of Spraying. 



I know of no subject that is of more vital importance than 

 the one to be discussed this afternoon, that of the care of our 

 orchard trees, in consideration of some of the great dangers 

 which threaten them at the present time. 



We are comparatively a new country and we have not as yet 

 that high appreciation of trees as is held in older countries. 

 We have most ruthlessly destroyed a vast territory that has 

 been covered with forest trees, a territory which made the nat- 

 ural home of insects which, so long as they could be maintained 

 in their natural homes, were not pests ; but when we have so 

 ruthlessly destroyed our forests we have not been sufficiently 

 wise to replace the trees, thus we have thrown out upon our 

 cultivated fields many kinds of insects that have become pests. 

 At this time when we desire to plant orchards or to raise choice 

 fruits we fmd an infestation of so many kinds of insects that we 

 are confronted with the fact that whoever plants fruit trees 

 must protect them from insects. Few of us have made a study 

 of msects because until recent years there has been no occasion 

 for the farmer to be an entomologist. The man who attempts 

 to plant orchards without a knowledge of the msects that attack
