worm dust crowded and compacted together, some of which 

 becomes crowded out through a crack in the bark or a hole 

 made by the worm. It is by seeing this sawdust-like pow- 

 der protruding out of the bark that we detect the presence 

 of these borers in the tree." It feeds here for about a year, 

 and has then grown strong enough to attack the solid wood, 

 into which it bores a cylindrical hole three or four inches, 

 inclining upwards- towards the centre of the tree, and then 

 curving outwards until Its upper end comes to the bark. 

 Here it makes its bed, to repose in during its pupa state. 

 Shortly afterward it reaches the winged state and crawls out 

 of the tree. 



Remedies must be applied early. At first the insect 

 may be cu out with the point of a knife. If deep in the 

 wood it may be punched to death in its hole by a flexible 

 wire. To prevent the insect from laying its eggs in the bark, 

 apply a wash of strong soap-suds and flour of sulphur 

 towards the end of spring and early summer ; repeat the 

 operation if the rains wash this off. 



Says D. L. Tracy, of Longmont : The best remedy 

 against the borer is good soap-suds with a good stout cloth 

 to rub with. Rub the body and limbs until they shine, at 

 least once a week.
