It may seem at first, very unaccountable that bees should go on to fill their hives with comb unfit for breeding, when the young queen will so soon require worker-cells for her eggs; but it must be borne in mind, that bees, under such circumstances, are always in an unnatural state. They are attempting to rear a new queen in a hive which is only partially filled with comb; whereas, if left to follow their own instincts, they never construct royal cells except in hives which are well filled with comb, for it is only in such hives that they make any preparations for swarming. It must be confessed that they do not show their ordinary sagacity in filling a hive with unsuitable comb; but if it were not for a few instances of this kind of bad management, we should perhaps, form too exalted an idea of their intelligence, and should almost fail to notice the marked distinction between reason in man, and even the most refined instincts of some of the animals by which he is surrounded.
The determination of bees, when they have no mature queen, if they build any comb at all, to build such as is suited only for storing honey, and unfit for breeding, will show at once, the folly of attempting to multiply colonies by the dividing-hives. Even if the Apiarian has been perfectly successful in dividing a colony, and the part without a queen takes the necessary steps to supply her loss, if the bees are sufficiently numerous to build a large quantity of new comb, (and they ought to be in order to make the artificial colony of any value,) they will build this comb in such a manner that it will answer only for storing honey, while they will use the half of the hive with the old comb, for the purposes of breeding. The next year, if an attempt is made to divide this hive, one half will contain nearly all the brood and mature bees, while the other, having most of the honey, in combs unfit for breeding, the new colony formed from it will be a complete failure.
Even with a Huber hive, the plan of multiplying colonies by dividing a full hive into two parts, and adding an empty half to each, will be attended with serious difficulties; although some of them may be remedied in consequence of the hive being constructed so as to divide into many parts; the very attempt to remedy them, however, will be found to require a degree of skill and knowledge far in advance of what can be expected of the great mass of bee-keepers.
The common dividing hives, separating into two parts, can never, under any circumstances, be made of the least practical value; and the business of multiplying colonies by them, will be found far more laborious, uncertain and vexatious, than to rely on natural swarming. I do not know of a solitary practical Apiarian, who, on trial of this system, has not been compelled to abandon it, and allow the bees to swarm from his dividing hives in the old-fashioned way.
Some Apiarians have attempted to multiply their colonies by putting a piece of brood comb containing the materials for raising a new queen, into an empty hive, set in the place of a strong stock which has been removed to a new stand when thousands of its inmates were abroad in the fields. This method is still worse than the one which has just been described. In the dividing hive, the bees already had a large amount of suitable comb for breeding, while in this having next to none, they build all their combs until the queen is hatched, of a size unsuitable for rearing workers. In the first case, the queenless part of the dividing hive may have had a young queen almost mature, so that the process of building large combs would be of short continuance; for as soon as the young queen begins to lay, the bees at once commence building combs adapted to the reception of worker eggs. In some of my attempts to rear artificial swarms by moving a full stock, as described above, I have had combs built of enormous size, nearly four inches through! and these monster combs have afterwards been pieced out on their lower edge, with worker cells for the accommodation of the young queen! So uniformly do the bees with an unhatched queen, build in the way described, that I can often tell at a single glance, by seeing what kind of comb they are building, that a hive is queenless, or that having been so, they have now a fertile young queen. When a new colony is formed, by dividing the old hive, the queenless part has thousands of cells filled with brood and eggs, and young bees will be hourly hatching, for at least three weeks: and by this time, the young queen will be laying eggs, so that there will be an interval of not more than three weeks, during which no accessions will be made to the numbers of the colony. But when a new swarm is formed by moving, not an egg will be deposited for nearly three weeks; and not a bee will be hatched for nearly six weeks; and during all this time, the colony will rapidly decrease, until by the time that the progeny of the young queen begins to emerge from their cells, the number of bees in the new hive will be so small, that it would be of no value, even if its combs were of the best construction.
Every observing bee-keeper must have noticed how rapidly even a powerful swarm diminishes in number, for the first three weeks after it has been hived. In many cases, before the young begin to hatch, it does not contain one half its original number; so very great is the mortality of bees during the height of the working season.
I have most thoroughly tested, in the only way in which it can be practiced in the ordinary hives, this last plan of artificial swarming, and do not hesitate to say that it does not possess the very slightest practical value; and as this is the method which Apiarians have usually tried, it is not strange that they have almost unanimously pronounced Artificial swarming to be utterly worthless. The experience of Dzierzon on this point has been the same with my own.
Another method of artificial swarming has been zealously advocated, which, if it could only be made to answer, would be, of all conceivable plans the most effectual, and as it would require the smallest amount of labor, experience, or skill, would be everywhere practiced. A number of hives must be put in connection with each other, so as to communicate by holes which allow the bees to travel from any one apartment to the others. The bees, on this plan, are to colonize themselves, and in time, a single swarm will, of its own accord, multiply so as to form a large number of independent families, each one possessing its own queen, and all living in perfect harmony.
This method so beautiful and fascinating in theory, has been repeatedly tried with various ingenious modifications, but in every instance, as far as I know, it has proved an entire failure. It will always be found if bees are allowed to pass from one hive to another, that they will still, for the most part, confine their breeding operations to a single apartment, if it is of the ordinary size, while the others will be used, chiefly for the storing of honey. This is almost invariably the case, if the additional room is given by collateral or side boxes, as the queen seldom enters such apartments for the purpose of breeding. If the new hive is directly below that in which the swarm is first lodged, then if the connections are suitable, the queen will be almost certain to descend and lay her eggs in the new combs, as soon as they are commenced by the bees; in this case, the upper hive is almost entirely abandoned by her, and the bees store the cells with honey, as fast as the brood is hatched, as their instinct impels them always, if they can, to keep their stores of honey above the breeding cells. So long as bees have an abundance of room below their main hive, they will never swarm, but will use it in the way that I have described; if the room is on the sides of their hive, and very accessible, they seldom swarm, but if it is above them, they frequently prefer to swarm rather than to take possession of it. But in none of these cases, do they ever, if left to themselves, form separate and independent colonies.
I am aware that the Apiarian, by separating from the main hive with a slide, an apartment that contains brood, and directing to it by some artificial contrivance a considerable number of bees, may succeed in rearing an artificial colony; but unless all his hives admit of the most thorough inspection, as he can never know their exact condition, he must always work in the dark, and will be much more likely to fail than succeed. Success indeed can only be possible when a skillful Apiarian devotes a large portion of his time to watching and managing his bees, so as to compel them to colonize, and even then it will be very uncertain; so that this plausible theory to be reduced to even a most precarious practice, requires more skill, care, labor and time, than are necessary to manage the ordinary swarming hives.
