We believe that not only does a glass present a much handsomer appearance when thus worked--and will, on that account, most fully reward the trouble of fixing guide-comb--but that more honey is stored in the same space and in less time than if the glass be merely placed on the hive in a naked condition for the bees to follow their own course. This mode of fixing guide-comb does not solely apply to the above-shaped glass, but is equally useful for all kinds of glasses. It is introduced in connection with this glass because, from its having a flat top and no knob, the regularity is more clearly apparent. The working of bees in the bell glasses illustrates how tractable their disposition really is if only scope is allowed for the due exercise of their natural instinct. They have no secrets in their economy, and they do not shrink from our constant observation as they daily pursue their simple policy of continuous thrift and persevering accumulation. Yet it is only owing to the labours of successive inventors that we are now enabled to watch "the very pulse of the machine" of the bee commonwealth. "Long from the eye of man and face of day, Involved in darkness all their customs lay, Until a sage well versed in Nature's lore, A genius formed all science to explore, Hives well contrived in crystal frames disposed, And there the busy citizens disclosed." Murphy's Vanière. § XIII. APPLYING SUPERS. Supposing the hive to be a stock (page 81), the super should be applied at the early part of the season, say, if fine and warm, at the latter end of April or beginning of May; but if the weather is then unfavourable it is better to delay doing so until a more genial temperature. If the colony is a swarm of the present year, two or three weeks should be allowed to elapse from the time of tenanting a hive before putting on the super; this delay is necessary to give the bees the opportunity of building combs in their new domicile, and of getting a store of honey for themselves before working for their master. The exact time[28] will, however, depend much upon the weather, and the same applies to the subsequent time occupied by the bees in filling the super. They will be the more incited to commence their work, and having commenced to continue it, if some warm covering is placed over the glass; at night, when much comb-building goes on, it is important to wrap it in flannel or worsted, or some warm material (a baize bag is convenient for bell glasses). A further inducement will be offered by the fixing of a piece of comb to the bars or ventilating tube, as the case may be. The cells on the outside or by the window are always the last to be filled, so that when these are sealed over it is safe to conclude that the rest are also complete.
