SHELTERING. 341 
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 efficiently. 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.
