During the early period of Huber's investigations, he prosecuted them by means of single comb hives which allow of each side of the comb being examined. He found, however, that these had one important defect. The bees could not in these hives cluster together, which is their natural method of withstanding the effects of a reduced temperature. Huber hit upon the ingenious expedient of combining a number of single comb frames so as to form one complete hive, which could be opened in order to expose any particular comb, without disturbing the rest. From the manner of the opening and closing of this hive, it has generally been called the "Leaf or Book Hive." The division separating each comb is joined both back and front with "butt hinges," fastened with a moveable pin, on withdrawing which, at either side, each comb and the bees on it may be inspected as easily as if in a single comb hive. Huber's Leaf Hive is thus in appearance as if several of those "History of England" back-gammon chess boards were set up on end together. The floorboard on which the hive stands is larger than the hive when closed, so as to allow of its being opened freely at any particular "volume." An entrance way for the bees is hollowed out of the floorboard as in other hives. There is a glass window in each end of the hive, which is provided with a shutter. There is, however, one serious objection to Huber's hive, which, though not noticed by him or his careful assistant, has prevented its general use. That is, the difficulty there is in closing it without crushing some of the bees, a catastrophe which, by exasperating their comrades, is certain to interfere with any experiments. There is no such risk in the Bar and Frame Hive, whilst in it every facility possessed by Huber's is retained; so that we strongly recommend scientific apiarians, in preference to Huber's, that they should use some kind of Bar and Frame Hive. We have here introduced a description of Huber's Leaf Hive (and should be glad to exhibit one) for the sake of its historic interest in connection with apiarian science. The invention was invaluable for Huber himself, and it suggested to other apiarians the adoption of the present plan of vertical bars and frames.
