D D are ventilators. In the centre of each of the end boxes is a double zinc tube, reaching down a little below the middle: the outer tube is a casing of plain zinc, with holes, about a quarter of an inch wide, dispersed over it; the inside one is of perforated zinc, with' openings so small as to prevent the escape of the bees; a flange or rim keeps the tubes suspended through a hole made to receive it. The object in having double tubing is to allow the inner one to be drawn up, and the perforations to be opened by pricking out the wax, or rather the propolis, with which bees close all openings in their hives. These tubes admit a thermometer, enclosed in a cylindrical glass, to be occasionally inserted during the gathering season; it requires to be left in the tube for about a quarter of an hour, and on its withdrawal, if found indicating ninety degrees or more, ventilation must be adopted to lower the temperature. The ornamental zinc top D must be left raised, and is easily kept in that position by putting the perforated part a little on one side. The boxes before described are placed on a raised double floor-board, extending the whole length--viz., about thirty-six inches. The floor-board projects a few inches in front. In the centre is the entrance (as our engraving only shows the back of the hive, we must imagine it on the other side); it is made by cutting a sunken way, of about half an inch deep and three inches wide, in the floor-board, communicating only with the middle box; it is through this entrance alone that the bees find their way into the hive, access to the end boxes and the super being obtained from the inside. An alighting-board is fitted close under the entrance, for the bees to settle upon when returning laden with homey. This alighting-board is removable for the convenience of packing. The centre, or stock-box A, called by Mr. Nutt the _Pavilion of Nature_, is the receptacle for the swarm. For stocking this, it will be necessary to tack the side tins so as to close the side openings in the partition, and to tack some perforated zinc over the holes at top; the swarm may then be hived into it just the same as with a common hive. A temporary bottom board may be used if the box has to be sent any distance, or a cloth may be tied round to close the bottom (the latter plan is best, because allowing plenty of air); and when brought home at night, the bees being clustered at the top, the cloth or temporary bottom must be removed, the box gently placed on its own floor-board, and the hive set in the place it is permanently to occupy. E E are two block fronts, which open with a hinge. A semicircular hole, three inches long and two inches wide in the middle, is cut in the upper bottom-board, immediately under the window of each box; these apertures are closed by separate perforated zinc slides. These blocks, when opened, afford a ready means of reducing the temperature of the side boxes, a current of air being quickly obtained,
