if sound and worth saving, should be cleaned and thoroughly disinfected 

 with a strong solution of carbolic acid or izal. 



On the evening of the fourth day following, the necessary number of 

 frames for the hive should be furnished with full sheets of comb-founda- 

 tion, to be exchanged with those the bees have been working on. This 

 can be done by removing the frames one at a time, shaking the bees back 

 into the hive, and inserting the others. The comb built on the starters 

 during the four days may be cut out and melted up, and the frames 

 disinfected. 



The theory of this treatment is that during their four days' comb- 

 building the bees use up all the infected honey contained in their honey- 

 sacs when taken from their old hive, so that when shifted again at the 

 end of the four days they start clean. 



After-inspection. 

 In from three to four weeks, when the new brood begins to emerge, 

 keep a look-out for any suspicious-looking brood-cells, and if any are 

 seen cut them out at once, together with the adjoining cells. " Eternal 

 vigilance ' ' should be the watchword of every beekeeper ' who hopes to 

 keep down disease. 



To PREVENT S WARMING OUT. 



On rare occasions colonies swarm out during treatment, but this is 

 not likely to occur when honey is being gathered freely. It can be 

 guarded against by caging the queen for a few days, or by giving a wide 

 entrance and placing queen-excluding zinc across. 



Saving Healthy Brood. 



When several colonies are to be treated and there is a large quantity 

 of healthy brood in the combs, put a queen-excluding zinc honey-board 

 over the frames of one of the least- affected hives, and put all the healthy 

 brood above this to emerge. When this has been accomplished remove 

 everything and treat the colony in the manner advised. The zinc pre- 

 vents the queen making use of the affected combs while the brood is 

 emerging 



Autumn Treatment. 



When it is desired to treat colonies in the autumn after hrood-rearing 

 hag ceased, just put the bees into clean hives provided with ample winter 

 stores in the shape of frames of honey from clean colonies. The disease 

 is not likely to reappear. 



Feeding and Disinfecting. 

 In all cases when treatment is going on and honey is not being stored 

 freely, feed sugar-syrup liberally after shifting the bees on the fourth 

 day. Mix half a pint of water with each pound of sugar used, stir well, 

 and bring it to the boil; when cool it is ready. Always feed within the 

 hive and in the evening.
