REMEDIES FOR THE CANKER-WORM 





the 'Bodlime' applied by a man who was an expert in the 

 use of the trowel. I ordered material sufficient for 200 trees 

 and they sent me 200 lbs. which cost $15, on cars in Bos- 

 ton. The freight charges and the labor charges brought the 

 cost per tree up to about ten cents per tree. We removed the 

 ' Bodlime ' about July i , as you recommended. It seemed to be 



very effective, so much so that we 

 shall not apply it to our orchard 

 next year. The application was 

 made April i and 2. This was 

 just a little too late, in my opinion, 

 as some of the moths had gone up 

 before the application was made. 

 However, I think it was effective 

 enough so that I shall not make 

 the application the ensuing year. 

 If the canker-worms show any in 

 the orchard in the year 1902, I 

 shall make two applications of 

 'Bodlime' — one about Nov. i, 1902, 

 and the next March 15, 1903. I 

 shall put a little higher than the 

 bands where the 'Bodlime' was ap- 

 plied the previous November. I

to take off the moths that were caught each night to prevent 



their bridging the bands with their dead bodies." 



This banding method is particularly serviceable in the case 

 of orchards which are likely to be badly infested, because it 

 prevents the injury that is bound to occur before the canker- 

 worms in such an orchard can be killed by spraying. It also 

 is especially useful in protecting large elm trees, which are 

 difficult to spray on account of their height. 



If thoroughly applied, the bands being kept on throughout 

 the entire season, during which the moths and caterpillars of 

 both species appear — from October till June — this banding 

 method is easily applicable to orchard practice. In cases 

 where the attack the previous season was severe, it will gen-
