there ig an outer case or cover, also of half-inch 
wood, thirteen to thirteen and a half inches square 
within-side, made half an inch higher than the 
nether, its top and bottom boards inclusive. The 
outer case is closed on all 
sides except the top and back 
(see Fig. 2). Upon it rests 
the floor-board of the stock- 
hive, which may be of inch 
wood, showing a_ projection 
all round of an inch, except 
at the front, where an addi- 
tional three inches is given to 
form the alighting-board, this 
part bevelling forwards. A 
square of half-inch wood must 
be screwed to the under side 
of the floor-board, of a size to 
drop easily within the square 
of the outer case, thus re- 
taining it in its place. Be- 
tween the two pieces of which 
the floor-board ig composed, 
a groove is ploughed out, 
from front to back, two inches 
wide, to receive a zinc divid- 
ing slide, pushing in from 
behind. An opening, about three inches long, is 
cut through the floor-board, towards the front, and 
also through.the cover of the nether, to correspond, 
so that a passage for the bees can be opened on 
withdrawing the divider (see Fig. 6).
