tection is necessary but many experiments 

 have indicated that it is a practice not 

 likely to be overdone. 



In experiments by Demuth and Phil- 

 lips, of the Department of Agriculture, 

 it was found that one of the most con- 

 venient ways of packing was to place four 

 hives together in a large packing case, 

 leaving little tunnels to the entrances. 

 This packing case was insulated by a layer 

 of three inches of material below the hives, 

 five inches on the ends, six inches on the 

 sides and from eight to twelve inches on 

 top. They state that the amount of pack- 

 ing used was effective for the latitude of 

 Washington, D. C, but that farther north 

 greater thickness would probably be 

 needed. It will be noted that the great- 

 est thickness of insulating material was 

 used on top of the hives. This agrees with 

 the practice long employed by many bee- 

 keepers and still in use in a great many 

 places. Prior to the experiments of 

 Demuth and Phillips it was not generally
