this is a measure people are very reluctant to take, and 

 it is one consequently an entomologist does not like to 

 recommend (though it may be evident to him that in the 

 long run this would be economy both to the owner and 

 his neighbors.) Until the State enforces by law the de- 

 struction of such infested trees, we cannot, therefore, 

 hope for the prompt and drastic measures often needful 

 for stamping out the pests to which vegetation is sub- 

 ject. 



Injviries should be checked at their Inception 



and Precautionary Measures should 



be adopted. 



It is sometimes possible to prevent the increase of 

 an injurious insect with but slight trouble if we 

 know exactly what it is, and when our work may be 

 most profitably done. The cutting away and burning 

 of an infested branch, the removal and destruction 

 of an entire tree, sometimes even the removal of a 

 single insect, may save the trees of a whole village 

 from severe injury. Always dead portions of trees 

 either on the trees or lying on the ground are to be 

 removed and disposed of. Weeds and rubbish calculated 

 to afford lurking places for insects ought always to be 

 removed, and loose dead bark on the trunks should not 

 be allowed to remain. Though to many people a white- 

 washed tree trunk is an unsightly object, there can b» 

 no question as to the value of such treatment for some 

 injuries, and the wash may be made even more effective 

 by adding to it London purple or Paris green, when the 

 " tombstone effect " of which some people complain will 

 be done away with. 



It is a matter of common observation that the man who 

 attends to these things is much less troubled by" injury 

 to trees than one who neglects his grounds. Still there
