PREVENTIVE MEASURES. 



It is easier to use precautions than to combat the disease after it 

 has entered a district. If the following measures were followed, the dis- 

 ease would be less likely to spread: 



1. Do not feed bees honey the source of which you do not know. 



2. Transfer all queens received through the mail to clean cages, and 

 destroy the old ones, candy and all, including the bees accompanying the 

 queens. 



3. Do not move colonies from one place to another without thorough 

 inspection. It is against the law, if disease exists in the vicinity, unless 

 a permit is issued from the state entomologist. 



4. Contract the entrance to all weak hives, and inspect all colonies 

 not doing well, as soon as found. 



5. The purchase of second-hand combs and supplies is dangerous, 

 unless they are known to come from healthy districts. 



6. Do not put honey from diseased colonies on the market.
