ENEMIES AND DISEASES OF BEES 153 



of Agriculture, at Washington, D. C. Such 

 samples will be examined by an expert and. the 

 beekeeper informed as to the natiire of his 

 trouble without expense, to him. It is impor- 

 tant that the particular disease which may be 

 present be early determined, as the kind of 

 treatment necessary will depend upon which 

 disease is present. In the case of American 

 foulbrood it will be necessary to remove the 

 bees to a clean hive and deprive them of all 

 their brood and honey. The contamination 

 seems to be spread in the honey with this dis- 

 ease. If the disease is European foulbrood it 

 will be necessary to check brood rearing for a 

 time, and to requeen with a resistant strain, 

 preferably Italian. 



Sacbrood is a disease somewhat resembling 

 those just described. It is milder in form and 

 frequently disappears of itself during a honey 

 flow. The author usually requeens colonies 

 found to be affected with this disease and this 

 is usually sufficient.
