Passing now to the notice of some of these, we will draw attention first to "Nutt's Collateral Hive"--named from its first maker, who may be considered a pioneer in the improved modern methods. It consists of three boxes side by side, and having thin wooden partitions, with six or seven perforations, to admit of the passage of the bees from one compartment to another. These may be stopped by zinc slides. In the centre of the top is a wooden cover, to contain a bell-glass for supering. A ventilator over each of the side-boxes secures the proper temperature of these. "The grand object," as explained by Mr. Nutt, "is to keep the end boxes and the bell-glass cooler than the pavilion or middle box, so as to induce the queen to propagate her species there only, and not in the depriving (_i.e._ honey-storing) part of the hive. By this means the side and upper combs are in no way discoloured by brood. The queen requires a considerable degree of warmth. The bees enjoy coolness in the side-boxes, and thereby the whiteness and purity of the luscious store are increased." When the centre box is filled, access to the super and one side-box may be given by opening the slides. The glass is likely to be filled first, if kept warm by suitable coverings, and can be removed when the honey is sealed in the combs. If the season be very productive, one or both of the side-boxes may also be taken before the end of the summer, if sufficient stores are left in the central stock-portion, or if any deficiency be made up by judicious feeding. [Illustration: Fig. 47.--Modern Hives. Nutt's Collateral Hive in the Foreground.] The next and most important modification to which we come is the introduction of movable frames into hives, admitting of separate removal, either for examination as to conditions, or for the taking of honey. Bevan whose admirable work on _The Honey Bee_, published nearly half a century ago, is the foundation of modern systems of apiculture in this country--speaks of a straw hive with bars, instead of a solid top, invented by Mr. Golding, and named by him "The Village Hive." Even now we consider this variety might well be the cottager's introduction to the more enlightened methods of procedure; and it would, at the same time, satisfy, in large measure, old-fashioned prejudices in favour of straw for the material of the stock-hive. If the bars are properly furnished with "guides," straight and symmetrical combs may be secured, and the depriving of surplus honey-stores may be easily effected without murdering the workers. Previous to this invention, Réaumur, Bonnet, and Huber had suggested, and tried, the use of boxes with movable bar-frames. The last named apiarian is said to have borrowed his idea from the inhabitants of Candia, and he called it the "leaf-hive." In its original form it had eight frames, secured to each other by hooks and eyes, the external ones being glazed, and covered with a shutter.
