resulting in a reduction in tlie 

 vitality of the bees. 



It therefore follows that excessive 

 activity causes the consumption of 

 more food, resulting in more feces, 

 so that colonies on poor stores are 

 travtling in a vicious circle, which, 

 if the feces can not be discharged, 

 results in the death of the colony. 

 In the work here recorded no at- 

 tention was paid to the theory that 

 dysentery is due to an infection, 

 since there is nothing in the ob- 

 servations made that lends any sup- 

 port to that idea. If there is more 

 than one kind of dysentery, as has 

 been held, then the observations 

 here recorded must be considered 

 as applying only to the type which 

 can be relieved at once by an op- 

 portunity for flight. 



While the activity of the cluster 

 is greater at some times than at 

 others, there are not, as has been 

 held, regular intervals of activity 

 at which the colony rouses itself 

 to take food. At no time is a col- 

 ony kept at a room temperature of 

 45° F. or less in a condition which 

 can be characterized as inactive. 

 Presumably the reported "inter- 

 vals of activity" have occurred 

 when the colony made a noise due 

 to disturbance by a beekeeper. 



The bees in colony 3 were com- 

 pelled to work constantly to main- 

 tain so high a cluster temperature. 

 In fact, they did more work than 

 colonies wintered in the open air. 

 Keeping these bees in a cellar pro- 

 tected them from low outside tem- 

 peratures, but the lack of opportun- 

 ity for a normal ejection of feces 

 caused a condition more serious 

 than extreme cold weather. We 

 seem to have an explanation of 

 the fact, often observed by bee- 

 keepers, that some colonies winter- 

 ed in the cellar are in worse con- 

 dition in the spring than colonies 

 that are exposed to severe cold. 

 Poor food is evidently a more ser- 

 ious handicap than low tempera- 

 ture.
