whatever may be upon that top and fastened to it, may be moved round notwithstanding: this is what we particularly want in the construction of an observatory-hive, and must, therefore, be particularly attended to. A piece of clean, close-grained wood--beech, elder, mahogany, or any other firm wood--made much in the shape of our telescopic candlestick, but of not more than two inches and a half in height, with a bore through it of an inch in diameter, and turned, that is, wrought in a lathe, so that an inch of the top-part may enter into, and neatly fit, the cap fixed round the inch bore at the centre of the bottom-frame of the upper pavilion (Fig 2), and which cap is represented by the moveable top of the candlestick, is, as well as I can describe it, the pedestal to support the observatory-hive,--is, with the cap just mentioned, the compound, or double-hinge upon which that hive is turned round,--and is also the Bee-way into that hive. The way into the winter-pavilion, or octagon (g.) is made by cutting a circular hole through the very centre of the plane top, an inch in diameter, directly under the upward passage; so that the Bees, whether their way be into the summer-pavilion above, or into the winter-pavilion below, lies through the pedestal, and the only difference is, that one passage leads upwards and the other downwards. The covered-way which has been so often mentioned, may easily be made by taking out of the under-side of the bottom-board of the paneled and roofed box, made to secure the observatory-hive, and which is placed upon the top of the winter-pavilion, just as much as will allow a sufficient space for that way. Having completed the passages, my next business is--to describe the novel apartment into which the passage through the pedestal leads--that is, the real observatory-hive.
