The comb-honey producer is more exacting as to certain details of construction of hives than is the producer of extracted honey since it is more necessary for him to handle individual brood frames during the honey flow. The spaces[1] above and between the top bars of the brood frames must be accurate or they will be bridged with burr and brace combs and these filled with honey. Burr and brace combs make the removal and readjustment of the super and the manipulation of frames a slow and disagreeable task, to say nothing of the waste of material, which should have been placed in the sections in the beginning. The use of the slatted honey board (fig. 2), while preventing brace combs between itself and the super, does not prevent the building of burr and brace combs between and above the top bars of the frames. This trouble is largely eliminated by proper spacing. Most hive manufacturers are at present making the top bars of the brood frames of such a width that the spaces between them is from one-fourth to five-sixteenths inch with the same spacing above them. The difficulty, however, is in maintaining this spacing with any great degree of accuracy. Self-spacing frames[2] are a partial solution of this difficulty. In some localities, however, the ordinary self-spacing frames are so badly propolized as to render their removal from the brood chamber difficult as well as materially to interfere with the proper spacing. The advantages of such frames are then nullified, while their disadvantages are retained or even intensified. In such localities metal spacers having but small surfaces of contact are sometimes used. Some beekeepers prefer omitting the spacers entirely. However, some of the difficulties arising from the use of self-spacing frames are the result of carelessness on the part of the operator in not crowding the frames together properly when closing the hive after having handled the frames. [1] A bee space, or that space to which bees are least inclined to put comb or propolis, is perhaps a scant one-fourth inch. In hive construction one-fourth or five-sixteenths inch is usually used. [2] These are so constructed that the end bars are one-fourth or five-sixteenths inch wider than the top bars throughout a portion of their length or furnished with projections of metal fitted to the edges of the frame. In either case the adjustment is such that when the frames are crowded together in the hive the spaces between the top bars will be correct. =SECTIONAL HIVES.=
