"If honey is coming in freely, so that thin honey is shaken out of the 

 combs, cover the runway (D) with newspapers and shake the bees in 

 front of the new hive (B), leaving all frames in place and the cover on. 

 After the operation the soiled newspapers should be destroyed. In 

 shaking in front of the entrance the first one or two frames should be 

 so shaken that the bees are thrown against the entrance, where they can 

 locate the hive quickly. They then fan their wings and the others follow 

 them into the hive. If this is not done the bees may wander about and 

 get under the hive or in some other undesirable place." 



"After the bees are mostly in the new hive a queen and drone trap 

 (F) or a strip of perforated zinc is placed over the entrance to prevent 

 the colony from deserting the hive. The queen cannot pass through the 

 openings in the perforated zinc and the workers will not leave without 

 her. By the time that new combs are built and new brood is ready to be 

 fed, any contaminated honey carried by the bees into their new hive will 

 have been consumed and the disease will rarely reappear. If it should, 

 a repetition of the treatment will be necessary."

 in position of B) ; B, clean hive; C, empty hives to receive combs after shaking; D, hive

 drone trap; G. cover for clean hive B. From Farmers' Bulletin 442, U. S. Dept. of Agr.,

"Saving the healthy brood. — The old combs are now quickly removed. 

 If several colonies are being treated at one time it may pay to stack 

 several hive bodies containing contaminated combs over a weak diseased 

 colony to allow most of the healthy brood to emerge, thereby strengthen- 

 ing the weak colony. After 10 or 12 days this colony is treated in turn 

 and all the combs rendered into Avax. If only one or two colonies in a 

 large apiary are being treated it will not pay to do this." 



"Saving the wax. — Any but a very small apiary should have included 

 in its equipment a wax press for removing wax from old combs. After 

 the contaminated frames are taken to the honey house the combs should 

 be kept carefully covered, so that no bees can reach them until the wax 

 can be rendered. This should not be delayed very long or the combs 

 may be ruined by wax moths. The slumgum or refuse remaining after 

 the wax is removed should be burned. Contaminated combs should not 

 be put into a solar wax extractor for fear of spreading the disease. The 

 wax from contaminated combs may safely be used for the manufacture 

 of comb foundation." 



"Cleaning the hive. — The hive which has contained the diseased colony 

 should be thoroughly cleaned of all wax and honey, and it is desirable 

 that it be carefully disinfected by burning out the inside with a gasoline 

 blua-flama torch. If this piece of apparatus is not available .sev-
