We next come to the long floor, on which the three square Bee-boxes, (A. C. C.), which constitute _a set_, stand collaterally. This floor is the strong top of a long, shallow box, made for the express purpose of supporting the three Bee-boxes, and must, of course, be superficially of such dimensions as those boxes, when placed collaterally, require; or, if the Bee-boxes project the eighth part of an inch over the ends and back of this floor-box, so much the better; because in that case the rain or wet, that may at any time fall upon them, will drain off completely. For ornament, as much as for use, this floor is made to project about two inches in front; but this projection must be sloped, or made an inclined plane, so as to carry off the wet from the front of the boxes. To the centre of this projecting front, and on a plane with the edge of the part cut away for the entrance of the Bees into the pavilion, is attached the alighting-board, which consists of a piece of planed board, six inches by three, having the two outward corners rounded off a little. The passage from this alighting-board into the pavilion, (not seen in the plate, it being at the centre of the side not shown) is cut, not out of the edge of the box, _but out of the floor-board_, and should be not less than four inches in length, and about half an inch in depth; or so as to make a clear half-inch-way under the edge of the box for the Bee-passage. I recommend this as preferable to a cut in the edge of the box,--because, being upon an inclined plane, if at any time the wet should be driven into the pavilion by a stormy wind, it would soon drain out, and the floor become dry; whereas, if the entrance-passage be cut out of the box, the rain that may, and at times will, be drifted in, will be kept in, and the floor be wet for days, and perhaps for weeks, and be very detrimental to the Bees. In depth the floor-box, measured from outside to outside, should be four inches, so that, if made of three-fourths inch-deal, there may be left for the depth of the box-part full two inches and a half. Internally it is divided into three equal compartments, being one for each Bee-box: admission to these compartments, or under-boxes, is by the drawer and drawer-fronts, or blocks, which will be described presently.
