and tie that aroand the tree and let it fall over where it is tied and it 

 forms a loose, fluffy band and the moth cannot crawl over that on ac- 

 count of the fibres, neither can she pass over the tin. 



Q. How would it be in a rain and after this cotton gets packed 

 could they crawl over it then ! 



A. They probably could. 



Q. Mr. Murray — WhaL time would you put it on f 



A. The female of one species hatches out in the fall and deposits 

 her eggs, and another in the spring. 



Q, Then you have to put it on in the fall and in the spring ? 



A. You could leave it on all the time, but cotton soon packs so 

 it is better to put them on twice a year; tin is better because you can 

 put it on so they cannot get around; this spring some of the canker 

 worms hatched out as early as February. 



Q. Mr. Everington — What do those young feed on ? 



A. The female climbs up and lays her eggs, and they hatch out 

 about the time the leaves come out. 



Q. What may be expected of an orchard that has been infested 

 with canker worm this season and defoliated? Will it bring a crop of 

 fruit next year? 



A. If you keep the canker worms away, yes, sir, decidedly ; some- 

 times they disappear entirely, but that is due to parasites. 



Q. President Evans — Have you an idea what area of our State 

 has been infested with canker worms this year? 



A. I have not mapped it out yet, but I have all the information 

 on tile so I can say, I should think, about one-third of the fruit-grow- 

 ing region. 



Q. What would be the average destruction in each of those 

 counties? what proportion of orchards have been destroyed in the 

 counties that are infested? 



A. About one-sixth. 



Q. Mr. Hopkins — Suppose they are not destroyed and reappear 

 for two or three years in succession and destroy all the foliage, won't 

 that kill the tree ? 



A. No, the tree recovers so far as the leaves are concerned, but 

 you lose your crop. 



Mr. Hopkins — Last year the canker worm appeared in an orchard 

 of Dr. Ullman's, and I desputed it being a canker worm, because of the 

 fact that I had never seen it at that season of the year. 



Mr. Stedman — One specie is much more familiar than the other, 

 and that was the specie you was not familiar with.
