ingly. The front and 



gi" in depth. This is sufficiently 

 large to take eleven frames and one 

 dummy (93). The sides (h) are 19J" 

 X gi" X i", the front (t) is 17!'' x 8S* 

 X i", and the back, 17 J" x gi" x J", 

 rabbeted J' x J" at the bottom to rest 

 on and overlap the floor board. 

 These are dovetailed, and are nailed 

 together flush on the upper edges. 

 If put together with a double rabbet 

 nailed, the above measurements 

 must, of course, be altered accord- 

 back have two grooves running 



"sasaisE; 



from top to bottom, f" wide x i" deep, beginning ij" from 

 the ends. Two inner walls, iSJ" x 8i" x f", are fitted into 

 the grooves and are chamfered outwards on the upper 

 edges to carry the frames (Figs. 22, 39,) : they are nailed 

 i" below the top of the body box, so that when the body box 

 is placed in position upon the floor board the sides and back 

 overlap the floor board, and the front, being only 81" deep, 

 leaves a space of f" between it and the floor board as an 

 entrance for the bees. The inner walls being 4" below the level 

 of the sides and back, and J" distant from 

 the sides, the frames (97), when in position, 

 are level with the top of the body box, and 

 are prevented by the hive sides from moving 

 laterally (267). It will be seen that the body 

 box measures internally when complete i8" 

 X 14I" X 8i". This leaves a space of f" be- 

 tween the frame ends and the inner walls of 

 the body box, and a space of i" between the 

 bottoms of the frames and the floor board. 

 Four slips, 175" X J" X J", are nailed between 

 the tops and bottoms of the inner walls and 

 the hive sides, and a space of |" is left be- 

 tween the upper slips and the bottoms of the 

 frame shoulders. The spaces between the inner walls and the 

 hive sides are sometimes filled with cork dust, chaff or sawdust, 

 to preserve the heat of the brood chamber. The front (i) has 

 either a i" groove in the centre of the bottom, or an arrange- 

 ment in the porch in which run two doors [x) 8" x J" x-^^" so 

 that the entrance may be reduced, or enlarged, or closed as 

 required. Above the doors a porch (f) is provided to keep off 

 rain from the entrance. (See also 91, page 48.) 



87. The Lift or Riser (Fig. 20, C) measures internally 20" 

 long, 18" wide, and 12" deep, and is made of two pieces 2o|"x 12" 

 X J", and two pieces 18}" x 12" x f" dovetailed together. Four
