Winter Meeting. 223

condemned on this evidence alone. At the experiment station at 

 Columbia we tried to make an impartial test between the two, the 

 dust and the liquid, but at the end of the season there was not a 

 particle of difference between the two. That is, there was no rot on 

 any of them ; none whatever. 



Mr. George Murray. — The Canker Worm must have changed when 

 they got over in Illinois. I have never seen a liquid spray that would 

 kll the Canker Worm. 



LEAF ROLLER. 



(By Prof. J. M. Stedman.) 

 I simply wish to supplement my remarks last spring in regard 

 to the Leaf Roller, and I will say that since then I have worked out 

 the complete life history of the insect, and find that there is only one 

 brood a year ; that they hatch out in the early summer and deposit 

 their eggs, and then those eggs stay on your trees during the remainder 

 of the year, and hatch out next spring at about the time, or just a little 

 before, the blossoms open. I have some of the eggs here on a piece of 

 bark. It is not necessary to pass it around. If any of you wish to 

 see them after the meeting, you can come up and examine. You will 

 find that so far as the eggs are concerned it is almost impossible to 

 gather them during the winter, because these eggs are very dif-

THE "STING" IN THE APPLE.

 cause of the fact that it is used in advertising the Moth Catcher 

 so largely that everybody knows what I refer to. It is called there 

 a stinging insect), refering to the ichneumen, which I have always 

 said never did the stinging, I know absolutely it does not, because 

 I now know the insect that does do the stinging, although I did-not 

 at that time. All of you know that two years ago, and more or less 

 last year, the apples were stung by some kind of an insect that con- 

 verted what would otherwise have been a first class apple into a sec- 

 ond grade. That is where the damage comes. Now that was one of 

 the woist insects, one of the hardest insects to breed that I have 

 ever worked upon, and after having worked out its life history, I was 

 perfectly surprised to find that it was notlu'ng more or less than the 

 well known litlU' rascal, lln- plum curculio. 'I'hat plum curculio 

 when it comes to attack the apple work so entirely different from 

 what it docs in llic plum and cherry that nobody recognized the chap 

 from its work. Instead oi making a little hole in the apple and laying
