426 THE BEE-KEEPERS' REVIEW 



This new hive was quietly and quickly placed beneath the diseased 

 colony, the bee-escape board between. No smoke was used in this opera- 

 tion. The alighting board was removed and the front entrance escape 

 screwed on. The queen was run into the new hive at the entrance and 

 a queen-excluding zinc placed over the entrance. 



About dusk a half feeder full of syrup was given each colony so 

 treated if no honey was coming in. I waited about three weeks, when 

 I went to the hive, blocking the holes in the bee-escapes with rags. I 

 now brushed the bees from the bottom and carried the hive into a closed 

 room, where the rest of the bees were sulphured and the combs rendered. 

 This treatment was given in the fall of 1909. 



Upon going over the colonies the next spring that had been treated 

 by the McEvoy method, all were healthy with the exception of one which 

 showed the disease. In going over those treated on the bee-escape plan, 

 all showed three or four cells of the disease with the exception of one. 

 The only reason this one did not show the disease that I can see is that 

 their old queen was killed or superseded, for they had a young queen 

 in the spring. I was thoroughly discouraged, and decided to try the 

 McEvoy method again, shaking them only once on full sheets of founda- 

 tion, as there was no honey flow on at the time. I fed them one-half 

 feeder full of syrup in the evening.. In looking over them after they 

 had sealed a couple of batches of brood, I found they all showed the 

 disease. I was now determined to get rid of the disease, if I only had 

 one colony left, so I began to study the bee-escape plan again, and came 

 to the conclusion it was a failure on account of two reasons : 



First — Having a bee-escape in the center of the board, the bees from 

 above might have passed diseased honey to the ones below, which was 

 fed to the brood; there being some larvae in the combs. 



Second — I should not have used the frame of brood at all. Some 

 of the first bees emerging from the escape may have carried diseased 

 honey with them, which, upon being fed to the larvae below, started the 

 disease anew. The bee-escape plan was again brought into play, using 

 full sheets of foundation and no frame of brood ; tacking a piece of sec- 

 tion over the center escape so the bees could not go down that way. I 

 treated every one I could find diseased by this method, feeding them in 

 the evening when there was no honey flow on, and in every case when 

 treated by this method it was a complete success, not having found a 

 cell of foul brood since. 



I would not treat when the weather is too warm, unless the hive is 

 well shaded, because the brood is liable to get overheated or a comb is 

 liable to melt down, causing honey to run out of the cracks of the hive, 

 to be taken up by robber bees. Also be sure the colony to be treated has 

 honey enough to last them three weeks. If you have to feed, I advise 

 against a thin syrup, because of its souring and attracting robbers. In 

 using screws to fasten the board with the bee-escape onto the hive, I
