SHELTERING.

of January was a rather pleasant day. We took occasion 

 of this to examine our weak colonies, being anxious in 

 regard to their condition. To our astonishment, they were 

 found alive, and our disturbing them caused them to fly 

 and discharge their excrements. Being convinced that all 

 our bees were safe, we did not disturb the strong colonies, 

 and a few of the latter remained quiet. The next day, the 

 cold weather returned, and lasted three weeks longer. Then 

 we discovered that the weak colonies, that had had a clean- 

 sing flight, were alive and well, while the strong ones which 

 had remained confined, were either dead or in bad condi- 

 tion. 



640. In order to shelter bees more efiiciently. in out- 

 door wintering, against climatic influences, Apiarists have 

 devised hives, with double walls, filled at the sides, as well 

 as on top, with some light material non-conductor of heat. 

 Some are made on the same principle as the old two-story 

 double-wall L. hive (fig. 106) without packing.
