ith the tops of the two pieces
of red cedar, to form a ledge of about a 1/4 of an inch all round, to
support the sheets of perforated zinc, as shown at W W.

Sixteen pieces of mahogany, 1-1/8 of an inch broad, and half an inch
deep, are to be screwed to the mahogany floor board, commencing against
the piece of red cedar, R, and leaving a space between each piece, half
of an inch, and finishing against the other piece of red cedar with the
last; there will then be formed fifteen grooves, half of an inch in
width, half an inch in depth, and 9-1/2 inches long on the floor-board
as shown at 1, 2, 3, 4, 5, 6.

A bar of mahogany, Y Y, about two inches square, having grooves,
X X X X, &c., corresponding to those on the floor-board, 1, 2, 3, 4, 5,
6, &c., is let in, and fastened between A and C, having a clear space of
twelve inches between the floor-board, and this top bar; the object of
these grooves being to receive, and keep steadily in their places, the
fifteen bee-frames, when introduced into them.

[Illustration: _Fig. I._]

The "bee-frames" are made of mahogany, nine inches long, twelve inches
high, and half an inch broad. Each frame is _dove-tailed_ to make it
strong at the angles, and to keep it true; the upper part is formed of
one inch mahogany, and _bevelled_ off (as the carpenters call it) to the
eighth of an inch, in the centre, as shown at _a_, fig. 1: on the two
sides of this triangular bar, _b b_, pieces of glass, extending the
length of the bar, are fixed with red lead. The two sides of the frame,
_d, d_, are to increase in size, from half an inch at the top, to 1-1/2
inches at the bottom. The bottom piece, _c_, is half an inch in depth.
The back of each frame has a piece of tin, about the thickness of a
card, fixed on it, of the exact size, viz. twelve inches long, and half
an inch broad, _e, e_. In the centre of the back of each frame, _f_,
a screw-nut is let in, which is made to fit a screw at the end of a
long spindle, S, Plate I, fig. 1. This spindle with a handle, Z, will
screw equally well into the screw-nuts of the fifteen bee-frames and
division-frame. The use of this spindle being, to draw in and out of the
grooves the fifteen bee-frames when required. When the bee-frames have
been put into the grooves in the box, slips of tin about thirteen inches
long, and and a half broad, are slipped into their backs (being run in
between the backs of the bee-frames, and the pieces of thin tin fixed
upon the
