descriptions and illustrations, and various methods of circumventing and 

 destroying them ; one of which, at least, is cheap and efficient. So that 

 there seems to be no good reason why orchardists should have their trees 

 damaged by this enemy. 



Mr. Robison — I have understood that some of Dr. LeBaron's reports 

 are difficult to get. 



The Secretary — They may be in separate form, but I have quite a 

 good supply of copies of the Reports of this Society which contains 

 them. 



Dr. Long — I am well acquainted with this canker-worm, and have 

 no trouble in keeping it out of my orchard. Late fall or winter plowing 

 is the remedy j no matter how badly your trees are affected, two seasons' 

 "fighting it out on this line " will give you the victory. What you can 

 not turn with the plow, turn with the hoe or spading fork, and the cold 

 will kill them. I know what I am talking about ; you need not fear the 

 canker-worm, if you will attend to this matter of late plowing. 



Mr. Wier — I was about to suggest, that as Dr. LeBaron's reports 

 are out of print, it might be well to have a new edition published with 

 the forthcoming volume.* 



■^ Acting upon this hint, I present the following quotation from Dr. LeBaron's 



second annual report, taken from the fifth vohmie of Reports of Transactions of Illinois 



State Horticultural Society, giving one of the preventive measures referred to for the 



canker-worm : 



" Take a piece of inch rope — old worn out rope is 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 around 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 endwise, so that they shall he long enough to go around the trees over the 

 rope. Put one of these strips around the tree outside the rope, so that the rope shall 

 be in the middle of it ; let the ends lap a little, punch a hole through them and fasten 

 them with a nail driven through them and the rope into the tree. * * * * * * 

 " This obstruction prevents the females, which are destitute of wings, from ascending 

 the tree to deposit their eggs under the bark of the trunk and larger limbs, and they 

 will deposit them l>c/o7c> the obstructrm, and generally within a few inches of it." 



These bands should lie put on as early as March first, in the latitude of Chicago, 

 and proportionately earlier or later to the south or north; As the eggs hatch before the 

 red currant blossoms, the bands should be taken off before this time, or before April 

 twenty-fifth, in latitude of Chicago, and dipped in scalding water, and the trunks of 

 the trees below the bands to the ground should be well treated to kerosene oil, applied 

 with a brush ; then replace the bands. One application of kerosene is sufficient, and 

 will not hurt the trees. 



Other methods of destruction, both before and after hatching, are given in the 

 volume referred to. — Editor.
