300 SUMMER. 



full-grown worm, while in a lower temperature it 

 would require weeks and even months in some cases, 

 perhaps from fall till spring 



TIME OF TRANSFORMATION, 



The worm, after spinning its cocoon, soon changes 

 to a chrysalis, and remains inactive for several days, 

 when.it makes an opening in one end and crawls out. 

 The time taken for this transformation is also governed 

 by the temperature, although I think but few ever 

 pass the winter in this state. It is a rare thing to find 

 a moth before the end of May, and not many till the 

 middle of June ; but after this time they are more 

 numerous till the end of the season. 



FREEZIN& DESTROYS WORMS, COCOON AND MOTH. 



It is pretty well demonstrated that the moth, its 

 eggs, larvae and chrysalis cannot pass the winter with- 

 out warmth of some kind to prevent their freezing to 

 death. The following facts indicate this. I have taken 

 all the bees out of a hive in the fall, and without dis- 

 turbing the comb or honey, put it in a cold chamber 

 where it could freeze thoroughly. In the following 

 March bees were again introduced, and when not on a 

 bench with some other stock that had worms, not a 

 single instance in forty cases has ever produced a 

 worm before the' middle of Jane, or until the eggs of 

 some moth matured in another hive has had time to 

 hatch. I have sometimes, instead of putting bees ia 

 these in March, kept them till June for swarms, per- 

 fectly free from any appearance of worms !
