 alive and well, while the strong ones which had remained eon-

 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. 131) without packing.

The most wide-spread style, is the chaff-hive, of A. I.

 chaff, dry leaves, or a cushion of any warm material. Some 

 Apiarists also use one-story chaff-hives with loose bottom-
