3. Glass.--Some bee-keepers like to be able to make a full and daily inspection of the hive; we have therefore prepared a few hives, constructed of wooden frames enclosed on all sides and on the top with window-glass. The dimensions are precisely the same as those before mentioned, and allow the same number of bars and frames (ten). The crown has a round hole cut in the glass to admit of feeding. The four sides are constructed of double glass, to preserve the bees from variations of temperature. We cannot, however, recommend this hive for a winter residence for the bees; we should prefer lifting the combs out and placing them in a straw hive of similar construction, to pass through the ordeal of the winter season (Chap. V. § xx.). Such a hive is an object of much interest, as in it the whole commonwealth of bees is exposed to view; and it need not be obscured from daylight, provided it be protected from sun and rain. All the external woodwork can be stained, varnished, or made of polished mahogany; so that the appearance of the glass frame hive is extremely neat, and much approved of. § X. NEIGHBOURS' NEW FRAME HIVE. [Illustration] I. Wood.--Since the former editions of this work were published, several alterations and improvements have been made. We find, in the first place, that a deeper hive than the Woodbury is desirable for the better concentration of heat, and also to admit of more honey being stored above the brood, so that the food shall be easier of access to the bees in winter. Our new frame hive measures accordingly twenty-one inches from front to back, sixteen inches in width, and twelve in height, thus allowing the sides to be constructed of the original breadth of the planks, viz., eleven inches (the other inch being made up by the thickness of the floor-board). The frames, of which there are nine, are ten inches deep and thirteen wide; they rest on strips of zinc, which prevent the bees from propolising them down so firmly, and, as the outsides of the hive are so enlarged as to leave galleries from side to side beyond the ends of the bars, there is easy access allowed to the fingers in removing. Another noteworthy improvement is the addition of a "dummy frame," which is merely a thin piece of board of the same size as a frame, and whose use is either to contract the dimensions of the hive according to the population, or to make room, by its removal for the extraction of the first comb.
