For want of proper precautions, the bees of this hive perished, during the intense cold of January 1820.
On the 25th of March following, Mr. Dunbar introduced another swarm into the same unicomb hive; and so early as the 27th, he saw the queen laying the eggs of workers. This second swarm found plenty of honey and farina in the hive, left by its former tenants. Other particulars reported by Mr. Dunbar are detailed in the Chapters to which they belong.
These hives are of course only useful to the amateur apiarian, who is in quest of information or amusement.
Huber carried the principle of this hive still further: he joined several thin boxes together with hinges: these boxes or wooden frames were without glasses, and the hinges were so contrived as to admit of easy removal. Every box or leaf (as Huber called each separate frame), except the two exterior, was reduced in thickness to an inch and quarter, which, as there was a free communication between all the leaves, afforded the same liberty for the operations of the bees as the single box that was an inch and half wide. This contrivance gave him the power of opening the leaves separately, and inspecting the proceedings of the bees at all times: they soon became accustomed to this treatment, and M. Huber was thus able to examine any one of the divisions, without exciting the anger of the bees. After they had properly secured the pieces of comb which he had attached to the roofs of the boxes, they were subjected to a daily inspection by this indefatigable naturalist.
The preceding sketches may serve to show my readers the progressive proceedings of the bees in the unicomb hive, and the following outline may give them a notion of the compound hive.
