Insects Injurious to the Potato and Apple. 593, 



the spring. In Yermont I do not tliink that many come 

 from the cocoons in the fall, and very few if any come 

 ont during the winter ; so tliat it i^ in spring only that 

 we are to expect them in any numbers. Tliey attack other 

 trees beside the apple, such as the wild cherry and elm. 



As to remedies, the following are more or less effectual, 

 and all have l)een tried fully. I give them as the best that 

 have come under my notice. 



To prevent the passing of moths up the trees, tarred 

 strips, troughs of oil, etc., are all effectual, if properly 

 used, Le Baron recommends putting a band of rope or 

 twisted hay around the tree, and over this a tin band four 

 inches wide, so placed that the rope shall be in the middle 

 of the band — i. e., put the rope two feet from the ground, 

 or less, and fasten the ends with a shingle nail ; then take 

 a strip of tin four inches wide and long enough to go 

 around the tree over the rope ; let the ends of the tin lap, 

 and nail tln-ough them and the rope to the tree, thus making 

 a sloping band. This has been found to effectually prevent 

 the ascent of the moths. If tliis is used, the moths will then 

 lay their eggs below it, and, of course, the same remark 

 applies to any band tliat keeps them down, and these must 

 be destroyed by kerosene brushed over the trunk. If, how- 

 ever, these remedies have not been used, as they lay their 

 eggs for the most part on the under side of the l)ark scales, 

 on the trunk or larger branches, if the tree be thoroughly 

 scraped and the scrapings burned the number of worms the 

 following season will be greatly lessened. If the worms 

 have hatched they can be removed from trees that are not 

 too large by jarring them down and catching them in a
