Within-side the box, two pieces of red cedar of half an inch in thickness, 12-1/8 inches long, 9-1/2 inches broad, are nailed on to each end at E F, and E F (one of the pieces of red cedar shown at R). The quadrants, Q Q, being made to work between them and the outer case. A fillet, _v v_, is fastened on a level with 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 them), to close the 1-1/8 of an inch openings. And three or four sheets of perforated zinc are laid upon the tops of the bee-frames, resting on the fillets. Thus, then, when a swarm of bees has been
