The floor-board is of mahogany, the border being French polished. A middle-sized bell-glass, for deprivation, is placed over the hole; this hole may be closed by a zinc slide. A cover of straw, eighteen inches deep, fifteen inches wide, with a zinc ventilating top similar to that affixed to the cottage hive, completes the arrangements. The weight of the stock-hive and board is about 16 lbs. This hive is well adapted for those persons who are desirous of having the opportunity of more closely examining the workmanship of these industrious and interesting insects, as the whole of the interior may be exposed to view; it is particularly suitable for a window or an indoor apiary, and will also be found a valuable addition to the green-house. Under these circumstances, the entrance-way should be covered with a flat piece of glass, and an aperture cut in the sash corresponding with the entrance to the hive; through the glazed passage the bees may then find egress and ingress without being able to gain access to the apartment. An alighting board, four inches wide, must be fixed outside, on a level with the entrance. We had a hive of this kind in operation at the Great Exhibitions of 1851 and 1862, fixed after the manner above described. It answered admirably, and excited much interest and curiosity, though placed there under many disadvantages. When a hive of this kind is to be stocked, procure an early and strong swarm, which must be temporarily hived in a common straw hive, from which dislodge the bees into the glass hive, but for this purpose a little preparation will have to be made. Spread a sheet on the ground, place the mahogany floor-board on it with the support, put three bricks, or some solid blocks of about the same substance, upon which the glass will rest; then, with a sharp and sudden blow, precipitate the swarm out of the straw hive on to the floor-board and support, place the glass hive on the bricks, and the bees will collect under the bars and on to the pedestal. In about one hour's time the whole will have settled quietly and all the stragglers on the board will have collected together, the swarm hanging pear-shaped from the bar support; the bricks can now be removed, and the glass put in its right place on the floor-board. The straw cover being put on the hive, it can be removed to the place it is destined permanently to occupy. The light should not be admitted for some days after hiving; if undisturbed, the bees will speedily build comb, working from the wooden bars, which are placed there for their assistance and support. In ten days or a fortnight, if the weather continue fine and warm, they will prepare to swarm again; the opening at the top must now be unstopped, and the bell-glass put on, guide-comb having been previously fixed. The directions given for the improved cottage hive equally apply to the ladies' observatory hive.
