Chapter II: Part 2

The beekeeper can do much (1) toward increasing the percentage in the first group and discouraging those of the second--_preventive measures_, and (2) toward making the most of the colonies under the third and fourth groups--_control measures_.

=PREVENTIVE MEASURES.=

Some effort has been made toward the final elimination of swarming by breeding from colonies showing the least disposition to swarm. Although after years of selection bees continue to swarm when conditions are favorable, many practical beekeepers testify to having greatly reduced the percentage of swarming colonies by years of careful selection and breeding. It would certainly seem advisable to replace the queens of all colonies which persist in swarming with young queens reared from colonies less inclined to swarm. The swarming problem has also been attacked from the standpoint of the hive and mechanical attachments, finally resulting in the invention of a "nonswarming" hive. More attention has, however, been paid to the prevention and control of swarming by manipulation than along either of the other fines, probably because proper manipulation gives immediate results and is now available as a means of preventing the losses due to swarming. The success in swarm control attained by the best beekeepers is a result of some effort along all three of the above fines at the same time.

Among the manipulations that tend to discourage swarming are (1) the introduction of young queens (preferably reared from selected stock); (2) an abundance of empty comb in the brood chamber at all times previous to the honey flow; (3) prompt work in the supers at the beginning of the flow induced by using "bait sections" or extracting combs in the first super given, thus tiding the colony over one of the critical periods; (4) a judicious manipulation of the supers during the honey flow (p. 41); (5) the use of more nearly perfect worker combs in the brood chamber, since drone comb and imperfect cells (p. 22) have the effect of contracting the brood chamber, thus bringing about a crowded condition; (6) an abundance of ventilation during the honey flow, obtained by means of a large entrance or by raising the hive above the bottom board by means of small blocks; (7) protection of the hive from direct rays of the sun during the hottest portion of the day by some such means as a double cover or shade board; (8) the removal of one or two frames of brood and the substitution therefor of empty combs or sheets of foundation; (9) the destruction of all queen cells provided they contain only eggs or very small larvæ.

If queen cells are well advanced, their destruction usually has little or no effect as a swarm preventive measure. While destroying queen cells in their early stages can not be relied upon as a preventive of swarming, beekeepers who practice examining the brood chambers once a week for queen cells during the swarming season are usually surprised at the number of colonies that can be induced to give up swarming and turn their attention to storing in this way. Such a result at least partly compensates for the large amount of labor required for these weekly examinations.

=CONTROL MEASURES.=

After having taken all precautions as to preventive measures there win still be some colonies that will attempt to swarm when producing comb honey. During poor seasons of course the percentage may be quite low, but during good seasons the conditions are sometimes such that a majority of the colonies may make an effort to swarm. Swarming colonies, however, may be controlled in such a manner that practically as much surplus honey is secured as if the colony made no attempt to swarm. If but a single apiary is being operated and the beekeeper is present during the swarming season, the bees may be permitted to swarm naturally without loss to the beekeeper; but if several apiaries are being operated, it is more economical to employ some method by which swarming may be controlled by visiting each apiary at given intervals during the swarming season, rather than to have an attendant at each.

=Control of Natural Swarms.=

Natural swarms may be managed (1) by allowing them to cluster naturally, then hiving them in the ordinary manner; (2) by the clipped queen method; (3) by the use of queen traps (fig. 13; see Farmers' Bulletin No. 447, pp. 29-30); or (4) by use of the swarm catcher.[4]

[4] This is simply a wire-cloth cage large enough to be set over the hive or be fitted over the entrance. If the attendant is provided with a number of these catchers he can avoid the usual confusion ordinarily occurring when several swarms issue at about the same time. After being caught in this manner the swarms may be hived at the convenience of the beekeeper.

To keep the forces together (1) the swarm without the queen may be returned to its hive, the queen cells destroyed a week later, and the colony afterwards requeened (p. 36); or (2) the brood may be removed from the hive while the swarm is out, after which the swarm with the queen is returned. The former method is useful under some conditions (p. 37), but the latter is the one usually preferred.

When the swarm is hived back without the brood on its old location in this manner, the colony does not lose any of its flying bees and is back at work with renewed energy in the same set of supers it was but a few minutes before so eagerly deserting. Instead of removing the combs from the brood chamber the usual practice is the removal of the entire brood chamber and the substitution of another whose external appearance is the same. This method of swarm management keeps the bees, queen, and supers together and is one of the most satisfactory known. It is not, however, adapted to out-apiaries or any apiaries not having an attendant, and requires considerable time in watching for and hiving swarms.

=USING THE REMOVED BROOD TO BEST ADVANTAGE.=

The disposition of the brood that is left when a swarm issues should be such that (1) no "after-swarms" (swarms resulting from the emergence of a plurality of virgin queens) are permitted to issue and (2) that the emerging workers may be used to the best advantage.

"After-swarming" may be prevented by (1) breaking up the parent colony before any of the young queens emerge, using the unhatched brood elsewhere, (2) by destroying all queen cells but one before any young queens emerge, or (3) by greatly reducing the population of the parent colony[5] just before the young queens emerge.

[5] The term "parent colony" applies to the one in the hive from which the swarm issues and is in common use, though the correctness of the term is questionable.

If swarming occurs at a time when the resulting young bees can take part in gathering and storing the crop of honey, the usual practice is to allow the brood to emerge in a separate hive and later to add these young bees to the colony from which it was taken. Under such circumstances this reenforcement of the swarm is especially desirable, since otherwise its forces are constantly diminishing during the 21 days (the time required for worker brood to develop) immediately following the removal of all its brood. The brood, however, may be used anywhere in the apiary and should be placed where the resulting bees will be most needed. The plans given below make use of at least a part of the emerging bees in reenforcing the swarm from which the brood was taken.

When hiving natural swarms on the old location as suggested above, the old brood chamber is provided with a bottom and cover and set aside, usually with its entrance turned away about 90° from its former position (figs. 14, 15). This is to prevent any field bees returning to the parent colony. A day or so later it is turned about 45° toward its former position (fig. 16) and as soon as the bees have this location of the entrance well marked the hive is placed parallel to the hive on the old stand (fig. 17). So far as the bees returning from the field are concerned, these two colonies are now on the same stand.

The further disposition of the remnant of the brood and young bees may be by any one of the following methods: (1) One week after the swarm issues, or just before the parent colony would cast a second or "after-swarm," it may, when the bees are well at work in the fields, be removed and given a new location. This throws the entire flying force into the colony having the supers, where they are of greatest service, and so depletes the other colony of its flying bees just when the young queens are emerging that "after-swarming" is usually prevented. (2) Before moving it, away the parent colony may be more thoroughly depleted of its young bees by shaking most of them from their combs, adding them of course to the colony with the supers. The comb containing the finest queen cells should not be shaken, since to do so will probably injure the immature queens. Two or three frames should be left with their adhering bees in order that the parent colony will still contain enough workers to care for the remaining unemerged brood. (3) Instead of moving the parent colony away as in (1) above, the bees may all be added to the swarm by shaking them from their combs, and the combs then distributed among nuclei previously prepared. By successive additions of frames of brood these nuclei are finally built up into full colonies and "after-swarming" is prevented. (4) Instead of giving the parent colony a new location, as in (1) above, it may be shifted to the opposite side of the swarm on the old stand (fig. 18) and by thus shifting it from one side to the other at intervals of several days the young bees as they hatch and learn to fly will finally all be added to the colony with the supers. Few beekeepers, however, go to this extreme, as the season usually closes before the latest emerging young bees are thus transferred to the colony with the supers and these later-emerging bees may be used for increase at little if any expense in surplus honey. (5) If increase is not desired, the bees may be added to the swarm on the old stand as before, and after 10 or 15 days the combs of the parent colony still containing some unhatched brood may be used on which to hive another swarm. Before being used for this purpose the bees are of course shaken from these combs and added as before to the swarm on the old stand. (6) If the honey flow is of long duration or conditions otherwise such that the storing colony may prepare to swarm again, the brood chamber of the parent colony may be left by the side of the swarm (fig. 18) until the young queen begins to lay, then restored to its original position on the old stand and the supers transferred to it. The brood chamber containing the old queen is moved to one side, its flying bees thus induced to enter the hive containing the young queen. The two colonies may afterwards be united or the one containing the old queen may finally be moved to a new location for increase. If, when using this plan, a virgin queen or a ripe queen cell is given the parent colony just after the swarm issues, this colony is ready to be restored to its original position on the old stand about a week earlier than if left to requeen itself.

In case the emerging bees are not to be added to the storing colony the brood and young bees may be used in one of the following ways:

(1) They may be used immediately after the swarm issues to build up such colonies as are not strong enough to work in the supers or to build up previously prepared nuclei, as in (3) above. Before being used in these ways the adhering bees are usually added to the swarm.

(2) The parent colony may be placed at once on a new stand and given a laying or virgin queen. To allow such a colony to requeen itself usually results in its casting an "after-swarm," since it becomes quite populous again before the young queens emerge. This plan does not make immediate use of the emerging bees but may be useful under some conditions. (3) If the honey flow is of long duration or is followed closely by a second, two parent colonies, as in (2) above, may be placed upon the same stand, one of which is given a queen but with the queen cells destroyed in the other. After two or three weeks the bees may be shaken from the queenless colony in with the queen-right one. Such colonies are in excellent condition for rapid work in the supers.

=WHAT TO USE IN THE BROOD CHAMBER WHEN HIVING SWARMS.=

(1) The use of narrow strips of foundation 1 inch or less in width in the brood chamber offers some advantages. (_a_) When the brood chamber contains only these narrow "starters" and supers of partly filled sections are transferred from the parent colony to the new swarm at the time of hiving, there being no cells below in which to store the honey, it is taken to the supers. Under these conditions work in the brood chamber goes on slowly, the work of the colony being largely in the supers. (_b_) Colonies that are thus required to construct a set of new combs in the brood chamber and that are supplied with sufficient storage room seldom attempt to swarm again during the same season, even though the flow be of long duration. (_c_) The treatment of brood diseases may be combined with swarm control. (See Farmers' Bulletin No. 442, p. 14.) The greatest objection to their use is in the excessive amount of drone comb usually built when anything less than full sheets of foundation are used, especially if the queen is old or the brood chamber large in proportion to the size of the swarm.

(2) The use of full sheets of foundation in the brood frames has the decided advantage of resulting in straight combs having the maximum number of cells of the worker size, but is more expensive than the narrow strips and allows a more rapid building of comb in the brood chamber, which under some conditions is considered a disadvantage.

(3) The exclusive use of either narrow strips or full sheets of foundation in the brood chamber when hiving swarms necessitates the use for a short time of a queen excluder (fig. 2) if the supers are transferred from the parent colony to the swarm at the time of hiving, since otherwise the queen would probably enter the sections and a brood nest be established there. To avoid the use of queen excluders for this purpose, one or more empty combs maybe used in each brood chamber, the remaining frames containing full sheets of foundation. This empty comb also serves as a storage place for pollen that may be gathered before the other combs of the brood chamber are constructed. Otherwise this pollen may be stored in the sections (p. 46). It is also probable that fewer colonies will "swarm out" or desert their hives if hived in a brood chamber containing one or more empty combs than if foundation only is used. A disadvantage of this plan is that the cells near the top bar of the comb may be so elongated as to interfere with the complete drawing out of the foundation in the adjacent frame. Empty combs can not well be used in connection with narrow strips of foundation, since their use favors the construction of drone comb.

(4) Empty combs are sometimes used with the idea of saving the bees the work of constructing a new set of combs. Under same conditions this is false economy and gives poorer results than starters or foundation. With very strong colonies, or with the brood chamber contracted to five or six frames, empty combs in the brood chamber may give good results. Medium colonies on a full set of empty combs are included to store the honey in the brood chamber and neglect the supers.

(5) Combs of honey are sometimes used on which to hive swarms. In some instances the beekeeper uses frames of foundation or empty combs above the brood chamber previous to and during the first few days of the honey, flow for the purpose of discouraging swarming and afterwards uses these partly filled combs on which to hive swarms. In order to make room for the queen, this honey is rapidly carried above, and stored in the sections.

(6) Combs of sealed brood in which no eggs have been laid during the previous 10 days or 2 weeks may be used. Such combs are usually available toward the close of the swarming season from colonies that have swarmed 10 days or 2 weeks before. This plan is especially desirable when the beekeeper runs short of hives during the swarming season. In some localities, however, the character of the flow is such that the colonies may later again prepare to swarm when hived on either empty combs or combs of sealed brood.

=EXTREME CONTRACTION OF THE BROOD CHAMBER WHEN HIVING SWARMS.=

Some beekeepers contract the brood chamber, when hiving swarms, to five or six frames, the remaining space being filled by means of division boards or "dummies." This reduction in the capacity of the brood chamber results in practically all the honey being stored in the supers and also restricts brood rearing at a time when the resulting bees develop too late to become gatherers. This is especially adaptable to locations furnishing an early flow of white honey followed by a later flow of darker honey. The white or more marketable honey is stored in the supers and later the brood chamber is expanded and provisioned for winter with the less desirable honey. Some beekeepers accomplish a somewhat similar result by hiving two swarms together in a single hive body.

When practicing contraction it is best to give the full amount of room at the time of hiving the swarm and to reduce the space three or four days later, as otherwise the bees are apt to "swarm out" because of their cramped quarters. Since contraction of the brood chamber is but a temporary expedient, it should not be continued beyond the time that its use is of advantage. If there should be a later honey flow, the brood chamber should be expanded in time to rear the bees for it. In any event, contraction should not continue so long as to interfere with securing the proper conditions of the colonies for winter (p. 21). Frames of foundation, empty combs, frames of brood or honey may be used to complete the set of combs when expanding the brood chamber, and these are usually given just before or at the close of the honey flow. Contraction of the brood chamber to less than one hive body, except in hiving swarms, is not usually advisable.

=Swarm Control by Manipulation.=

Swarm control by manipulation enables the beekeeper to operate a series of apiaries by visiting each at certain intervals, thus eliminating the necessity of an attendant in each apiary during the swarming season. The fact that bees usually, by the construction of queen cells, indicate about a week in advance their intention to swarm, enables the beekeeper to control swarming by examining each colony once a week during the swarming period and forestalling the colonies that are making preparations to swarm. It is also possible to manipulate all the colonies before any swarming occurs so that most of them go through the honey flow without swarming, thus eliminating the weekly examinations.

Any manipulation for swarm control, whether applied after the colony has acquired the "swarming fever" or applied to all colonies alike previous to the swarming season, is based upon the single principle--_a temporary disturbance in the continuity of the daily emergence of brood_. This disturbance should occur just previous to or during the swarming season. In natural swarming the brood and the swarm are separated, the swarm being without hatching brood during a period of three weeks. The brood from which the swarm came may be allowed to emerge in a separate hive and the resulting bees may then be returned to the swarm (p. 29). In this way the swarming instinct is satisfied, at least temporarily, without materially decreasing the population of the colony. The beekeeper may anticipate swarming by removing the brood from the hive, allowing it to emerge in a separate hive and finally returning these young bees to the colony in the same manner as is done with the natural swarm. Under the same conditions the subsequent behavior of a colony treated in this way is similar to that of a natural swarm. In either case there has been a break in the continuity of the emergence of young bees in the hive during a period of three weeks.

Instead of hiving a natural swarm upon empty combs or frames of foundation, combs of emerging brood (without queen cells) taken from a colony that has been queenless during a period of 10 to 15 days may be used (p. 33) and a similar condition may be had without swarming by removing all of the brood and substituting such combs of emerging brood, thus at least temporarily avoiding swarming. In these cases there is a break of 10 to 15 days in the continuity of the daily emergence of bees.

A similar interruption of brood rearing may be accomplished by removing the queen from the hive or caging her within the hive during a period of 10 days or 2 weeks, then returning her to the combs. In this case no queen cells must of course be allowed to mature. A condition similar to this may be obtained without removing the queen by dividing the brood chamber into two parts with queen-excluding metal, for a period of 10 to 15 days. The brood from the division containing the queen is then removed and the bees, together with the queen, shaken into the other (queenless) division, the queen cells if any being first destroyed. The brood thus removed may later be returned to the colony in the form of young bees in the usual manner (p. 29). Even the destruction of the sealed brood by uncapping it has been advised as a means of swarm control. This gives a period of about 12 days during which few or no young bees emerge.

These methods are illustrative of the principle employed in the various methods of control by manipulation, which may be classified under three general headings: (1) Taking the queen from the hive. (2) Taking the brood from the hive. (3) Separating the queen and brood within the hive.

The following methods of swarm control are given for the purpose of illustrating the various types of control by manipulation. It is not to be understood that all the methods given are equally adaptable to any locality or season, but it is hoped that, presented in this way, the beekeeper may more readily see the principle underlying each plan as well as the basic principle underlying all the plans and thereby be better enabled to elaborate a system of control to meet his particular requirements.

=TAKING THE QUEEN FROM THE HIVE.=

The temporary removal of the queen from the colony for the required time (p. 36) and the return of the same queen is a method which has been used in swarm control. Of course, no queen cells should be permitted to develop in the meantime. Such colonies may prepare to swarm again, especially if the period of queenlessness is not more than 10 days. The method is a valuable one, however, and may be used at any time during the season on colonies making preparations to swarm.

=Dequeening in connection with requeening.=--Requeening each colony with a young queen early in the season may greatly reduce the percentage of colonies that attempt to swarm but can not be relied upon as a method of complete control since during a good and prolonged honey flow quite a number of such colonies prepare to swarm. If each colony is requeened with a young queen at the beginning of the honey flow, _after having been queenless for 10 or 15 days_, there will probably be very little if any swarming during an ordinary season. This method is not in general use among beekeepers, largely because of the difficulty in so timing the operation that there will be no loss. The following are illustrative of the various adaptations of requeening in connection with a period of no brood rearing.

(1) Just previous to the honey flow and at about the time that heavy brood rearing is no longer desirable, remove the queen from each colony, (_a_) Eight or ten days later destroy all queen cells but one and allow the colony to requeen itself, or (_b_) destroy _all_ queen cells 8 or 10 days after removing the queen, then after 3 to 6 days supply each colony with a "ripe" queen cell (one in which the queen is ready to emerge), a virgin queen, or a young laying queen. It is usually desirable that the interval of queenlessness be as short as possible without defeating its purpose. Some beekeepers give a young laying queen 10 days after removing the old one, or a virgin or ripe cell considerably earlier, sometimes even at the time the old queen is removed, while others prefer a period of at least 14 days before giving either a laying or a virgin queen. However, colonies with virgin queens sometimes swarm even though no other queen cells or larvæ from which to rear a queen are present. Another objection to the use of queen cells or virgin queens for this purpose is that some of the queens fail to emerge and some virgin queens fail to mate, thus leaving the colony hopelessly queenless. For these reasons, some prefer to have the young queens mate and begin to lay in "nuclei" (very small colonies) before introducing[6] them in the strong colonies. This method may be used for the entire apiary at the beginning of the honey flow or it may be applied only to those colonies making preparations to swarm.

[6] The young laying queens may be introduced Into the colony by the ordinary indirect or caging method (Farmers' Bulletin No. 447, p. 44) or together with a comb of brood and adhering from the nucleus from which she was mated.

(2) Use two hive bodies as a brood chamber before the honey flow, uniting if necessary to secure strong colonies. At the beginning of the honey flow divide each colony, leaving the field bees and most of the brood on the old stand in one hive body, placing the queen, remaining brood, and enough bees to care for it in the other hive body which is set beside the first. The supers are of course given to the queenless colony on the old stand, which after the proper interval of queenlessness is allowed to requeen itself or is requeened by the beekeeper as in (1) above. The colony containing the old queen may be used to strengthen the storing colony by shifting its position from one side of it to the other (p. 31), or used for increase.

(3) Ten days before the honey flow is expected to begin, put most of the brood into a single hive body, on this a queen excluder, and over this a second hive body with a frame of brood and the queen, the other combs of this set being empty except perhaps a little brood and honey. Nine or ten days later remove the upper story, supply it with a bottom board, and place it close beside the original hive. Destroy queen cells if any are present in the queenless portion which remains on the old stand, give a ripe queen cell, virgin queen, or a young laying queen, and put on the supers. The brood chamber containing the old queen may be used to make increase or its flying bees may be united with the storing colony (p. 31).

By any of these methods there is a break of 10 to 15 days in the continuity of brood emergence in the brood chamber left on the old stand and the colonies are requeened with young queens--each a strong factor in swarm control and when combined should with rare exceptions result in no swarming.

=REMOVING THE BROOD FROM THE HIVE.=

Since removing the brood brings about conditions quite similar to that of natural swarming (p. 28), such a management of the colonies is practically identical with that of natural swarming. The use of the brood that is removed (p. 29), the question of what should be used in the brood chamber instead of the removed brood (p. 32), the contraction of the brood chamber (p. 33), etc., have been discussed under natural swarming and need not be repeated here. While some of the plans using this principle may be applied to all the colonies in the apiary before swarming actually begins, the usual practice is to apply them only to such colonies as are making preparations to swarm. It should not be used on weak colonies, on colonies having a small percentage of sealed and emerging brood and few young bees, on colonies in which the queen is failing, or on any colonies during a very poor season. Under any of these conditions it is usually better to discourage swarming by destroying queen cells (p. 27), by removing one or two frames of brood, or, if some control measure is finally necessary, by requeening such colonies after an interval of queenlessness. On the other hand, for strong colonies having a high percentage of sealed and emerging brood and a good queen the method usually gives excellent results, since by its use the workers, queen, and supers are kept together during the flow. The following are some of the various plans employing this principle of swarm control:

(1) Find the queen and put the comb on which she is found to one side, then shake the bees from most of the other combs into or in front of their hive. As the combs of brood are removed put frames containing either narrow strips or full sheets of foundation or combs into the hive and replace the supers. When most of the shaken bees are in the hive, place the queen among them. Put all the brood and the few bees remaining thereon into another hive close beside the shaken colony (fig. 17). Enough bees should be left on the combs of brood to care for it; usually two combs are not shaken at all, but placed in the other hive with all the adhering bees. For further disposition of the brood see page 29.

(2) In order to avoid the trouble of finding the queen, the above plan may be varied by shaking and brushing _all_ the bees from the combs so as to be sure that the queen is among them. In this case the brood may be utilized by one of the following plans: (_a_) Use it to build up weaker colonies (p. 31) or (_b_) place it in a hive body over a queen excluder on top of the forced swarm or some colony not being used for comb-honey production that can spare enough bees to care for it. In a short time bees will pass through the excluder and cover the brood, after which the hive body containing it is removed, supplied with a cover and bottom board, and placed at one side of the forced swarm so that the emerging bees may later be added to the swarm. Or (_c_) after the shaking is complete, remove the forced swarm and put the hive body containing the brood temporarily back on the original stand to induce field bees to enter it. Then in the evening set it aside and restore the swarm to its position on the old stand. These field bees will be able to prevent the brood being chilled during the night but in returning from the fields the next day will enter the hive on the old stand. In the meantime enough young bees will have emerged to care for the brood.

(3) Removing all the brood and substituting frames containing narrow strips or full sheets of foundation sometimes results in the colony swarming out the next day. This may be avoided by removing the brood in two installments with an interval of a few days between the two operations. When the brood is not all removed, full sheets of foundation or empty combs should be used or an excessive amount of drone comb will be built.

With sectional hives, stand the brood chamber on end, smoke the bees out of the lower section, and remove it. Destroy queen cells in the upper hive section. These will almost universally be found projecting into the space between the two sections of the brood chamber. Substitute a new hive section containing empty combs or foundation for the removed section. After, a few days remove the supers, smoke the bees out of the upper section, remove it, and add it to the section that was removed before, which at the time of its removal was given the usual position beside the colony (fig. 17).

(4) Use two hive bodies as a brood chamber throughout the year except during the honey flow. Have both as well filled with brood as possible previous to the flow. About 10 days before the honey flow is expected to begin, insert a queen-excluding honey board (fig. 2) between the two hive bodies. The queen is now confined to a single one of the hive bodies. After 10 days transfer the queen[7] to the other hive body placed on the old stand and put on the supers. Remove the hive body in which the queen has been confined to one side of the colony on the old stand and supply it with a ripe queen cell (in a protector) or a virgin queen. When the young queen begins to lay, exchange places with the two hive bodies so that the one containing the young queen now becomes the storing colony, giving it the supers and field bees. Shift the hive containing the old queen from one side to the other of the colony on the old stand about once a week, so that the entire flying force of both are at work in the hive with the supers (p. 31). At the close of the honey flow the old queen may be killed unless she is especially valuable and the two divisions may be reunited. The period of 10 days during which no eggs are laid in the hive body used by the storing colony at the beginning of the honey flow should delay swarming at least until the young queen begins to lay. When the other hive body with the young queen is substituted, it has had a similar period of no egg laying in addition to having a young laying queen, making a desirable combination.

[7] It is not necessary to find the queen, since the presence of unsealed brood indicates In which hive body she is confined. She may be transferred to the other hive body by shaking all the bees from the combs she is known to occupy in with the bees of the other hive body. In this case some bees are returned to the shaken combs (p. 38) before this brood is set aside, to prevent its being chilled.

=Mechanical devices.=--A number of mechanical devices have been described for shifting bees from one brood chamber to another. These permit the bees to leave the hive when going to the fields and are so arranged that the returning bees are led to enter the new brood chamber. This is accomplished by means of switches in the bottom board or by a chute or tube so attached that the entrance to the old brood chamber is closed, allowing exit only through the tube which opens near the entrance of the new brood chamber. In either case the hives are so arranged that the bees returning from the field readily enter the new brood chamber. The queen is found and together with a comb of brood and adhering bees is put into the new brood chamber, and the supers are transferred from the old to the new brood chamber. The young bees as they learn to fly are added to the swarm by the same device. Otherwise the manipulation is the same as the other methods described.

=SEPARATING THE QUEEN AND BROOD WITHIN THE HIVE.=

In some swarm-control methods neither the queen nor the brood is removed from the hive, but these are temporarily separated within the hive. These methods are ordinarily used only on colonies making preparations to swarm and are practically equivalent to the dequeening plan. The following methods make use of this principle of swarm control:

(1) The queen may be placed in a wire-cloth cage within the hive or may be confined to a small comb surface within the brood chamber by means of queen-excluding zinc. No queen cells are permitted to mature, and the queen is liberated after 10 to 15 days.

(2) The queen together with a comb containing a small amount of brood is placed in a lower hive body containing no other frames or combs. After destroying all queen cells the brood is placed in a second hive body, the two hive bodies being separated by a queen-excluding honey board and the supers adjusted above the brood as before. The queen, being separated from the brood by means of the excluder, lays few eggs in the comb on which she is confined during this period of separation. After a week or 10 days the queen cells are again destroyed, and the brood and queen are put back into a single hive body as before. This method gives results quite similar to the dequeening method (p. 35).

If every season were alike in a given locality the beekeeper could work out a manipulation to be applied to each colony just before or at the beginning of the honey flow, which would result in practically no swarming. The wide variation in the seasons, however, renders it next to impossible to adopt a swarm-control measure that will prove most profitable every year. The means of control adopted must be such as to favor the domination of the storing instinct. Probably the plan of making weekly visits is the most widely used system of swarm control by manipulation. When a colony is found preparing to swarm, the brood is removed if conditions are such as to justify doing so (p. 37). Otherwise the removal of the queen is resorted to.

With any of these methods of control the colony may rapidly restore former conditions, and even though it has been diverted from swarming may later again prepare to swarm and require a second manipulation. Generally speaking, when the honey flow is short, less radical measures are required. Colonies that have been supplied with young queens after a period of queenlessness have one factor (the queen) changed with at least some degree of permanency. Colonies that have been compelled to construct a new set of brood combs from narrow strips of foundation have the most radical change of conditions as to brood rearing. Either of these changes alone is usually sufficient to insure no further preparations to swarm.

=Manipulation of the Supers.=

Proper manipulation of the comb-honey supers is not only a strong factor in the prevention of swarming but is also a stimulus to storing. The amount of room the colonies should have in the surplus apartment varies so much that the ordinary standard super is simply a unit in a large and flexible surplus apartment. If enough surplus room is given at the beginning of the season for the storage of the entire crop of honey, the space so given is too great for best results at the beginning of the honey flow, and little of it is needed at all if the season is poor. If, on the other hand, a single super is given and no other added until the first is completed, the room in the surplus apartment decreases from the time the super is given until the combs are completely drawn out, when there is little space left between the combs, the bees being practically crowded out. Thus while the population of the colony is increasing their room is being diminished--a condition highly conducive to swarming and less energetic work. After the super is filled, it is some time before the honey is ripened and sealed, ready to be removed. During this interval, if no other supers are given, there is no place for storage of the incoming nectar, and the comb builders must remain idle or waste their wax in building burr and brace combs. To avoid loss in this way, empty supers are added as they are needed, and the comb builders move from one super to another as their work in each is completed. The surplus apartment, whether consisting of a single super or several supers, should at all times contain some space for the comb builders.

If the honey flow is heavy and promises to continue, it is desirable to furnish not only sufficient room but to induce the bees to begin work in as many sections as possible, giving large comb surface for the storage and evaporation of the thin nectar, thus in a measure approximating extracted honey conditions.

There is a danger, however, that if the bees are induced to extend their work through too many supers, the sections when completed will be less well filled and therefore lighter in weight. Also, if the honey flow should not continue as expected a rapid expansion of the surplus apartment results in a large number of unfinished sections.

The rapidity of the expansion of work in the supers may to some extent be regulated by the position of each newly added super. If a rapid expansion is desirable, the empty super is placed below the supers already on the hive, while if it seems best to crowd the bees somewhat the empty super is placed above those already on the hive. When the empty super is placed above the partly finished ones, the bees do not begin work therein unless they need the room. This practice is always desirable during a slow honey flow or toward the close of any honey flow, but when nectar is coming in rapidly does not result in a rapid expansion of comb building sufficient to avoid a more or less crowded condition, which in turn causes a loss of honey and increases the probability of swarming. If each super is supplied with one or two extracting combs (p. 16), this disadvantage of the practice of placing the empty super on top largely disappears, since the extracting combs are immediately available for the storage of nectar.

When the empty supers are placed under the partly filled ones, work in them is commenced promptly, but this may be at the expense of the nearly completed sections, which by this plan are moved farther from the brood chamber as each empty super is added. In the case of the super in which the honey is being sealed this distance is an advantage in so far as the whiteness of the cappings is concerned, but it may retard the completion of the work. An arrangement of the supers that to some extent avoids this difficulty is as follows: Except toward the close of the season, place each newly added super next to the brood chamber and keep the one nearest completion just above it with all others arranged above these two, the one in which least progress has been made being on top (fig. 19). Thus super No. 1 is raised up and No. 2 placed beneath it. When No. 3 is given, it is placed next to the brood chamber, while above it is No. 1 with No. 2 on top. If No. 4 is given, it is placed next to the brood chamber with Nos. 1, 2, and 3 in order above it. By this arrangement, if conditions justify doing so, strong colonies may be induced to expand their surplus apartment with great rapidity, since as soon as the foundation is well drawn in each newly added super it may be transposed to the top and an empty one put in its place. Such rapid expansion of work in the supers should not be attempted, however, except during a heavy honey flow.

If early in the honey flow the bees are storing rapidly, strong colonies should be given a second super as soon as work has been fairly begun in the first. Colonies of medium strength may of course be allowed to do considerable work in the first super before the second is given, while a weak colony may have sufficient room for comb building until the first super is almost completed. The first super should contain some empty comb when given to the colony, and each succeeding super should be given in advance of the time when the bees would be in any way crowded without it. At no time should all the sections be removed and new supers containing only foundation be given, but the surplus apartment should contain sections in all the various stages of development. In this way there is no break in the work in the supers, and the critical periods, so far as the super room bears upon the problems of swarming and energetic work, are largely eliminated.

During the latter part of the honey flow the reasons for further expansion of the surplus apartment in excess of the immediate needs of the colonies (p. 41) no longer exist. At the beginning of a good honey flow the maximum of new work consistent with well-filled sections is desirable, while toward the close of the flow the beekeeper desires the minimum of new work consistent with sufficient room. The precise period when further expansion of the surplus apartment is no longer desirable and a concentration of the work already begun should take place is sometimes difficult to determine, and to do so requires a thorough knowledge of the locality and good judgment on the part of the beekeeper.

It is usually desirable to remove the honey as soon after it is finished as can well be done. If it is left on the hives too long after it is finished, it is likely to become discolored or "travel stained," while if it is taken off too soon some of the sections are not completed. It is desirable that the honey be removed by entire supers instead of by individual sections, therefore conditions should be made as favorable as possible for the completion of all the sections in a super without the more advanced ones becoming "travel stained." The bees are more inclined to stain the white surface of the combs toward the close of the honey flow or during very slow flows. Trouble from this source is at such time intensified because of the uneven progress of work in the different sections, the more advanced sections therefore being sealed some time before the super is sufficiently advanced to justify its removal. Another form of discoloration is brought about by the honey being sealed in close proximity to old and dark brood combs, in which case some of the darker wax from the old combs is sometimes apparently used for capping the honey.

During a good honey flow all except the last supers may be left upon the hives until all or nearly all of the sections of honey are sealed, since (1) there is little trouble from "travel stain" when work is progressing rapidly, (2) all the sections in the super are ready to be sealed at about the same time, and (3) when there are several supers on each hive the one in which the honey is being sealed is at least one super removed from the brood combs.

Toward the close of the honey flow all supers having most of their sections finished should be removed and the sections sorted. The unfinished sections should be graded according to the degree of completion, the various grades placed in supers and given to such colonies as are most likely to finish them. Every effort should be made at this time to contract the surplus apartment, concentrating the work upon the sections nearest completion. All supers in which work has not yet been started should be removed and as soon as possible the surplus apartment of each colony should be reduced to one super. Though little room is necessary during the close of the honey flow, there should always be some room for the storage of new nectar until it is ripened. For such conditions extracting combs are valuable, since, instead of giving the last comb-honey super in which little work would be done, a set of extracting combs may be placed over the sections to afford room for the incoming nectar and comb surface for its ripening.

=CARING FOR THE CROP.=

=Removing the Honey from the Hives.=

If the honey flow is of considerable duration the major portion of the crop is removed before the flow ceases. At this time the removal of the finished supers is comparatively easy because the bees can readily be driven from them and also because the operator is not hindered in his work by robbing bees. At the close of the honey flow all the supers remaining upon the hives should be removed promptly, since to leave them on would result not only in some of the honey being carried down into the brood chamber but also in badly propolized sections. After the honey flow has ceased, great care should be exercised to keep bees from robbing. The use of bee-escapes (fig. 12) greatly facilitates the removal of the honey at any time, but their use is especially desirable in removing the honey remaining on the hives at the close of the honey flow. By their use the honey may be removed and stored in the honey house with little disturbance or excitement among the bees. The supers of honey should of course be taken directly to the honey house or kept well covered[8] from robbers.

[8] Honey from out-apiaries should be loaded for transportation in such a manner that the bees can not get at it, then before the horse is hitched to the wagon the load of honey should be drawn by hand some distance from the apiary if the slope of the ground will permit doing so. If this is not possible the horse may be attached by means of a long rope and the load drawn to a safe distance before the horse is hitched to the wagon.

Before finally storing the supers of honey in the honey room those that are but partly filled may have their sections removed and sorted. The unfinished sections that can not be disposed of at a profit locally are usually put back into supers and the honey they contain is fed to the bees. This feeding is done by simply exposing the supers where the flying bees can have access to them. If there are few supers compared with the number of colonies they should be placed in piles and only a small entrance allowed, since if free access were given to a large number of bees they would tear the combs to pieces. When the bees have finished removing the honey from these unfinished sections the latter may be stored for future use as "bait" sections.

=Care of Comb Honey.=

In the honey room the supers of honey should be placed in piles in such a manner as to allow a free circulation of air between them. This may be done by "sticking them up" as lumber is piled to dry or by placing alternate supers crosswise. The air in the honey room should be kept as dry as possible. This is usually accomplished by means of a high temperature, the honey room being located on the sunny side of the building or directly under the roof. The windows should be opened only during dry weather. Ventilation of the honey room is of no value except when the air that is admitted contains less moisture than that already present. Otherwise ventilation may be a positive detriment. If a protracted period of rainy or damp weather should occur while the honey is in this storage it may be necessary to use artificial heat to dry the air in the honey room. Any great variation in temperature should be avoided, since it may cause a condensation of moisture on the surface of the cappings which will be absorbed by the honey.
