or bee-hive should be furnished with movable wooden bars, upon each of which, or at any rate upon every other bar, pieces of worker-comb should be fixed, to serve as a guide to the bees, prior to their introduction to a swarm. This, you will perceive, has been attended to in the hive and boxes before you. And it will be found that the bees, if they have their guide-combs correctly and securely fixed, will invariably accept them as the foundations of their future structures; by which means several important objects will be accomplished. In the first place, the facility of taking the stored honey will be very much increased. In the next place, if the bees are not wealthy enough to spare a whole box full of honey, you can without difficulty take from them what they _can_ spare. And thirdly, if in your apiary there should be any families _very_ unequal in wealth, provided the boxes and bars are reciprocally adapted to each other, one or more bars can be removed from a weak hive and exchanged for the same number of loaded bars from a strong one, thus giving needful support to one or more families without injury to any. In the performance of these operations, the use of a little tobacco smoke is required to paralyse the bees so far as to prevent them from being intrusive. But I will now endeavour to illustrate what I have stated to you, by having recourse to the boxes upon the table. I will suppose a swarm to have been introduced to one of them, and that the box and bees have been placed where they are to remain permanently. If your object be to collect pure honey, and to prevent swarming, as soon as you have ascertained that the box is about three-parts full of combs, another box should be placed either under or over the first, and a communication opened between them; if the season promise well, the family may be supered, if not nadired. In some remarkable seasons even a third box may be required; but this will rarely happen during the first year of a family's establishment. Indeed, during the first year honey should generally be rather sparingly taken. In future years, with good seasons, from thirty to forty pounds may be taken from each family; in highly favourable seasons, in a good locality, much more. I have now brought this lecture to a close. My chief difficulty in the composition of it has arisen from the exuberance of my materials, which it was not easy to compress into the form of a lecture. You will, of course, infer, therefore, that much has been left untold, for which I must beg to refer you to those works which have been written professedly on the subject.
