The frame hive in its modern form is, roughly, 
speaking, divided into two classes, and nearly all 
other types are merely modifications. First we 
have the double-walled hive on the celebrated 
““W.B.C.”’ principle. This hive consists of a 
floor-board with sunk entrance and detachable 
splayed legs, brood-box, eke and loose outer cases, 
covered with a span roof. All the sections are 
loose, and there is a free air space between the 
outer and inner walls, which tends towards an even 
temperature in the brood-nest. This hive may, 
be used for the production of either comb or ex- 
tracted honey, and if the former a special section 
rack, known as the ‘ W.B.C.” racks is used. In 
this rack the sections are worked in wide frames, 
which keep them clean, and also admit of their 
interchangeability in the event of a poor honey.

be completed while the outer rows are untouched, 
and by bringing the outer rows to the centre full — 
racks may be obtained. It may be said that both | 
comb and extracted honey, may be worked for at 
the same time. 
Our second type of hive is the well-known 
single-walled hive, and probably there are more of 
this kind in use than any other. Its name is 
rather a misnomer, as, strictly speaking, it is 
single-walled on two sides only; the other sides 
have inner walls placed for carrying the frame-
