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
