(2.) Thb body-box, or " brood chamber " (Figs. 1 and 30), rests 



on the floor-board, and overlaps it at the 



21. Body-Box of sides and back. This part of the hive is the 



0. D. B. Hive. permanent home of the bees. In it the 



frames are suspended in which the brood is 



raised and the winter food supply is stored. It should be made to 



contain at least ten, but preferably eleven frames (24), and a 



dummy (25) . It is fitted with two sliding doors opening to the 



flight-board, which is protected by a movable wooden porch. 



(3.) The lift, or raiser (Figs. 1 and 36), serves to raise the 

 roof sufficJiently to permit of crates (29) of 

 22. Lift of 0. D. B, sections, or boxes of frames for extracting 

 Hive. (31), being placed above the body-box, so 



that the bees can obtain access to them 

 from the brood chamber in order to fill the sections or super 

 frames with surplus stores of honey for removal. In winter 

 the lift should be inverted and slipped down over the body- 

 box (130). A second hft can be fitted on over the lower lift, 

 when it is desired to place more than three crates of sections 

 on the hive. 



(4.) The roof (Fig. 1) serves only as a protection from the 



weather; not to confine the bees. It is 



23. Eoof. fitted in front with two perforated brass 



cones (42), forming a non-return bee 



escape, and at the back with a perforated zinc ventilator. 



Bar-frames axe of the pattern known as the ' ' Abbott ' ' bar- 

 frame (Figs. 1, 9 and 30). They vary from 

 24. Bar-Frames, the dimensions of the" Standard ' ' frame as 

 fixed by the British Bee-keepers' Associa- 

 tion, in that the top bar is half -inch thick, instead of being only 

 three-eighths inch thick, as specified for the ' ' Standard ' ' frame ; 

 this extra thickness of the top bar is given to prevent sagging, 

 and to permit of itis being grooved to receive foundation : these 

 frames can be used in any hive constructed to take ' ' standard ' ' 

 frames, but should not be used in the same hive with ' ' stan- 

 dard ' ' frames unless the latter are raised to the same level by 

 fixing slips of wood one-eighth inch thick under the shoulders 

 of the ' ' standard ' ' frames ; otherwise the eighth-inch spaceB 

 above the shoulders of the ' ' standard ' ' frames would be filled 

 with propolis by the bees when the section-crates are on (110) . 

 The under side of the top bar of the " Abbott " frame is fitted 

 with two machine-cut grooves, separated by a very thin slip 

 of wood, running the whole length of the frame ; the foundation 

 (33) is fixed in position by inserting one edge of the sheet in 

 the centre groove ; a wedge-shaped slip of wood is then pressed 

 home in the other groove, thus tightly wedging the foundation 

 in position (73). The frames are kept at the correct distance 

 apart by the shoulders at each end of the upper bar. Bar- 

 frames should be made with the greatest accuracy as to 

 measurement so that they may all be exactly of one size ; it is,
