When the glass is nearly filled, which in a good season will be in a very short space of time, the Bees will again want accommodation. Previously, however, to drawing up the tin-slide to enlarge their crowded house, the manager should take off the empty end-box he intends to open to them, and smear or dress the inside of it with a little liquid honey. Thus prepared, he must return the box to its proper situation, and then withdraw the sliding-tin between it and the pavilion, or middle-box, and thereby enlarge the Bees' dominion, by opening an end-box to them, which will produce the greatest harmony in the hive. The Bees will immediately commence their operations in this new apartment. This simple operation, _done at a proper time_, effectually prevents swarming; and by it the Queen gains a vast addition to her dominions, and consequently additional space for the population of her enlarged domicile. There is now no want of store-house room, nor of employment, for our indefatigable labourers. And while the subjects are employed in collecting, and manufacturing (if I may so say) their various materials, the regina is engaged in carrying on the great, first principle of nature--the propagation of her species. This she does in the department (A.) re-filling with her eggs the cells which have been vacated by the young larvæ. When, however, her next new progeny are about to be brought into life, the Bee-master must draw out the other tin-slide, and thereby open a communication to the other empty apartment, and so make a further addition to the Queen's realm; which the new, and even veteran labourers, will presently occupy, and set about improving and enriching their again enlarged commonwealth. No sooner have the Bees finished their operations in the several compartments of their box-hive, which may be ascertained by looking through the little windows at the back and ends of the boxes, than the Bee-master gently puts in the tin-slide (1.) lifts up the lid of the octagon-box or cover (H.) and takes off the bell-glass, filled with the purest and most perfect honey. Before, however, he endeavours to take away the glass, it is necessary that he should cut through between the bell-glass and the box, with a fine wire, in order that the tin may the more easily slide under the full glass of honey; when this is done, he may take off the full glass and replace it with an empty one. He must then draw out the tin-slide (1.) and so on for even The operation of taking off a glass, or a box, of honey, may be best performed in the middle of a fine, sunny day; and in taking off a glass, the operator, having put in the tin-slide (1.) as already directed, should wait a few minutes, to see whether the Bees made prisoners in the glass manifest any symptoms of uneasiness; because, if they do not, it may be concluded that the Queen-bee is amongst them; and in that case it is advisable to withdraw the slide (1.) and to re-commence the operation another day. But if, as it generally happens, the prisoners in the glass should run about in confusion and restlessness, and manifest signs of great uneasiness, _then_ the operator may conclude that all is right, and, having taken off the octagon-cover, may envelope the glass in a silk handkerchief, or dark cloth, so as to exclude the light, remove it with a steady hand, and place it on one side, or so that the Bees may have egress from it, in some shady place, ten or fifteen yards from the boxes, and the Bees that were imprisoned in it will in a few minutes effect their escape, and return with eagerness to the pavilion and their comrades.
