Securing Workers for the Honey Flow.
Of course, the shorter the period for brood rearing previous to the honey flow, the more serious the problem of getting the colonies strong enough. Adverse weather conditions greatly retard brood rearing and thus have the effect of shortening this period. On the other hand, in some localities the main honey flow comes so late in the season that the colonies may even be divided and both divisions built up.
In most comb-honey localities the season is short and there is usually during the season only one honey flow that furnishes any considerable surplus suitable for comb honey, with perhaps other honey flows either very meager or furnishing honey unsuitable in color. The early minor flows are in such localities utilized in brood rearing in preparation for the main flow, and those occurring after the main flow may be utilized for winter stores, or if sufficient in quantity some surplus may be secured. In localities where the season is made up of a series of honey flows of almost equal importance and with sometimes a long interval between, the problem of securing workers for the harvest is rendered more complex, since the process must be repeated for each crop or the colonies kept very strong throughout the season. As a rule such localities are not the best for comb-honey production.
The workers that gather and store the crop of honey are those that emerge during the few weeks preceding and during the first part of the honey flow. Unless it is of unusual duration, the eggs that produce these workers are all laid before the honey flow begins, since those which develop from eggs laid later are not ready for work until after the close of the flow. On the other hand, the workers that emerge six weeks or more before the honey flow will have died of old age or be too old to be of much value during the flow. Their services, however, are of great value provided they expend their energy to the best possible advantage in rearing brood. If brood rearing ceases or is greatly restricted during this period, a colony that has been strong earlier in the season is rendered almost worthless as gatherers, since it begins the harvest with old and worn-out workers. This is exactly what often happens unless the beekeeper is alert and provides conditions such that brood rearing is not restricted during this period. In the clover belt, for example, it frequently happens that there is a scarcity of nectar during the period when the workers for the harvest should be reared and, unless the colonies are abundantly supplied with stores, brood rearing is greatly restricted. This may to some extent justify the saying among beekeepers that if the early flowers yield well the season will be good. The progressive beekeeper, however, provides conditions favorable to brood rearing even though the early flowers fail to yield nectar. It is therefore highly important (1) that each colony be in a normal condition at a period six or eight weeks previous to the honey flow, and (2) that brood rearing be at its maximum for the entire period of six or eight weeks during which the brood is reared to produce workers available for the honey flow.
BUILDING UP THE COLONY IN THE EARLY SPRING.
The condition of the colonies in the early spring depends upon many factors not all of which are under the control of the beekeeper. In the white-clover belt for instance, where the honey flow comes early, a large percentage of strong colonies in early spring means of course that they have wintered well, which in turn is largely dependent upon proper conditions the previous late summer and autumn. The manipulations having for their purpose the rapid upbuilding of the colony may therefore have their beginning at or even before the close of the honey flow of the previous year, including late summer and fall management and wintering. Good queens, preferably young, with enough room for breeding purposes and a supply of stores during the previous late summer and autumn are among the factors favoring good wintering. During the winter the central idea is the conservation of the energy of the bees, the complex details of which can not be presented in this paper.
The rapidity with which the colonies build up in early spring depends upon a number of conditions, some of which are: (1) The number and vitality of the workers; (2) the age and fecundity of the queen; (3) the supply and location of stores within the hive; (4) weather conditions; (5) the supply of new pollen, nectar, and water; (6) the conservation of heat within the brood nest; (7) the race of bees; (8) the character of the brood combs, etc. Most of these conditions are to a great extent within the control of the beekeeper. By supplying each colony with a young queen the previous autumn, or at least supplanting all undesirable ones, a greater number of young and vigorous workers are reared late in the season, which usually means greater vitality and numbers the next spring. Young queens reared the previous summer or autumn should be in prime condition the next spring. If to this combination is added an abundance of stores within the hives, brood rearing should progress rapidly, even in spite of adverse weather conditions. It is now the general practice among beekeepers to supply enough stores the previous autumn not only for winter stores but for brood-rearing purposes the next spring. Since the amount consumed during the winter varies considerably with different colonies, an early examination to determine the amount of stores may be necessary. Under some conditions it may be found profitable to stimulate brood rearing early in the spring by slowly feeding diluted sugar sirup to each colony, by spreading brood, or by doing both, but any very early stimulation of this kind should be used with caution. Among extensive beekeepers the tendency is decidedly toward letting the bees alone until the weather is more settled, simply making sure that they have sufficient stores. The apiary should, if possible, be so located that the bees may have access to water without the necessity of exposure of a long flight during bad weather. In localities that do not furnish natural pollen, it may be necessary to feed an artificial substitute, such as rye meal. A good hive that will conserve the heat of the cluster is also a great help in early brood rearing. Some beekeepers who winter their colonies in the cellar in single-walled hives find it profitable to give them some additional protection after they have been removed from the cellar. In the northern States double-walled hives are especially advantageous during the spring. A protected location for the apiary in some instances makes a great difference in early brood rearing. Some races breed up more rapidly in the spring than others. The Italians are somewhat conservative in this respect, but have so many excellent traits that they are generally used in this country. In localities having intermittent honey flows Italian bees may not give the best results because of their tendency to restrict brood rearing during the honey flow by crowding the queen and to curtail the production of brood during a scarcity of nectar. Drone comb within the brood nest in early spring is a decided barrier to rapid brood rearing. Many brood combs considered by the average beekeeper to be perfect contain, especially in the upper portion, a large percentage of cells which can not be used for rearing worker brood because of imperfections in shape and size due to the stretching of this portion of the combs during hot weather. This suggests the advisability of the use of a heavier grade of foundation or some method of using vertical wires or wooden splints in the upper half of the sheet of foundation.
THE PRODUCTION OF GATHERING BEES.
During the six or eight weeks just preceding the honey flow every colony should be encouraged to rear the greatest possible amount of brood. Brood rearing during this period is often restricted by insufficient stores or by insufficient room. It is therefore of great importance that both stores and available brood-rearing space be supplied in abundance. If stimulative feeding or spreading the brood is practiced, this is the time it should be done.
