CANKER-WORM. 



CANKER-WORM. 



We think we cannot render a greater service to the 

 community, at the present time, than to call the atten- 

 tion of cultivators to that destructive pest which so 

 long has foiled all attempts to destroy it. 



It is well known that some of these worms ascend 

 the tree in autumn. Those, therefore, who intend to 

 take measures of prevention should commence opera- 

 tions before the enemy has effected a lodgement from 

 which he cannot be driven. 



We fondly hope some cheaper, and more effectual 

 method may yet be discovered to save our ornamental 

 as well as our fruit-trees. Last summer the devouring 

 herd attacked the English cherry-tree and the rose- 

 bush for lack of their favorite food, and it is vincertain 

 where they will stop, if no attempts are made to arrest 

 their progress. 



We take from the New Haven Herald a well- written

 unknown hand in Philadelphia. We know not, at

 recommended. 



We would invite the attention of our citizens to the 

 following article on the canker-worm. The renewed 

 foilage with which our shade-trees are now covered 

 has in some degree removed the apprehension enter- 

 tained a few months since, that we were in danger of 

 losing one of the chief ornaments of our city. Our 

 citizens ought to be apprised, however, that the effort 

 required to put forth two sets of foilage annually, can- 

 not be sustained, ordinarily, longer than two or three 

 successive years. For one year, or two, this may 

 occur v/ithout serious detriment ; but the third year 

 commonly proves fatal to the tree. Many of our most 

 valuable ornamental trees have now been completely 

 denuded two years in succession, and, unless measures
