1X6 CANKER-WORM. 



inches or more wide, around the trunk and besmear it with tar, or a 

 mixture of tar and molasses, applied every other day. Roofing felt 

 besmeared with refuse printers' ink has been recently suggested as pre- 

 ferable. The method suggested in this Eeport is, to put a band of rope 

 or closely twisted hay around the trunk, and over this a tin band about 

 four inches wide, placed so that the rope shall be at the middle of the 

 tin, making a closed cavity below and a free edge of the tin above. 

 The time to use these appliances is, mostly, in the month of March ; 

 but also at other times when the weather is sufficiently open to permit 

 the insects to run. 



2d. If the moths are prevented from ascending the tree they will 

 deposit their eggs below the obstruction, and for the most part near to 

 it. These eggs cau be destroyed by a single application of kerosene oil. 



3d. If the moths are not prevented from ascending the tree they will 

 deposit tbeir eggs mostly upon the under side of the loose scales of bark 

 on the upper part of the trunk and the large branches. Many of these 

 can be destroyed by scraping off and burning the scales. 



4th. If all precautions have been neglected, and the eggs have been 

 permitted to hatch, then, as soon as the worms are large enough to be 

 easily seen, jar them from the trees and sweep them away with a pole, 

 as they hang by their threads, and burn or otherwise destroy them. 

 Strong washes, such as Paris green water, or suds made from the whale 

 oil soap, thrown upon the trees with a garden syringe, will also mate- 

 rially check their depredations. 



5th. If the worms have matured and gone into the ground for win- 

 ter quarters, plow the ground late in the fall, so as to expose the pupae 

 to frost and the action of natural enemies. The effectiveness of the 

 plowing will be increased if a few handfuls of corn be plowed in under 

 each tree, and the hogs be permitted to have the range of the orchard. 



The method of putting on the tin and rope bands mentioned in the 

 first paragraph is very simple. Take a piece of inch rope — old worn 

 out rope is just as good as new — tack one end to the trunk, two feet or 

 less from the ground, with a shingle nail, driven in so that the head 

 shall not project beyond the level of the rope ; bring the rope round 

 the tree and let it lap by the beginning an inch or two ; cut it off, and 

 fasten it in the same manner. Get the tin-man to cut up some sheets 

 of tin into strips four inches wide, and fasten them together end-wise, 

 80 that they shall be long enough to go round the trees over the rope 

 band, having the rope at the middle. Let the ends of the tin lap a 

 little, punch a whole through them and fasten them with a nail driven 

 through the tin and rope into the tree. *
