and its Economic Management. 119 



during the whole period the said out-apiary remained 

 perfectly free from the disease. I have stronger evidence 

 to show you yet, that even the bees themselves do not 

 carry infection by leaving their own diseased stock and 

 entering a clean hive, but this will be explained in due 

 course. 



4. — Bees flying from their own diseased hives do not carry 

 infection to any point of contact with other workers, from, or in 

 other hives, except only under the conditions of natural swarm- 

 ing ; e.g.: (a) No disease is communicated from flower to flower 

 in consequence of the visits of such bees, (b) No outside watering 

 or feeding apparatus is thus contaminated, (c) A bee flying from 

 its own {diseased) hive may enter a clean hive without danger to 

 the latter. 



In proceeding to give proofs in support of clause c, I 

 shall have shown sufficient to prove all other points 

 contained in my present proposition. 



Some of my most remarkable experiences occurred a 

 few years since, when I carried out a bold experiment 

 which entirely changed my own views as to the nature and 

 destructiveness of foul brood ; for whereas formerly I con- 

 sidered the combs must be destroyed utterly, I am now 

 able to point to perfectly clean combs which were at that 

 time diseased, and yet they were not medically treated in 

 effecting the cure. > 



The said experiment consisted in exchanging places 

 with two stocks ; one of which was badly diseased, but 

 strong in workers, old and young, while the other was 

 more backward but perfectly healthy. 



And the result ! Well, it will astonish the reader to 

 know that the healthy hive remained perfectly clean, 

 though it received the whole of the working force and a 

 great number of the younger nursing bees of the diseased 

 hive. But throughout this experiment it is to be distinctly 

 understood the dees were not first smoked or in any way
