Should the brood nest be restricted by a small brood chamber the colonies may be equalized by removing some frames of brood from the stronger colonies, exchanging them for empty combs taken from weaker colonies, or another brood chamber filled with empty combs may be given, thus building the colonies up individually. The former method has the following advantages: (1) After being built up to approximately the same strength, most of the colonies will be ready for a given manipulation at the same time, thus facilitating the work. (2) It requires a smaller stock of extra brood chambers and combs, at least previous to the honey flow. (3) The brood is in a more compact form, which is a very desirable condition in comb-honey production. (4) When properly done, the total number of young bees reared in a given time is probably considerably greater, owing to the fact that none of the colonies is strong beyond the capacity of the queen, the workers of the entire apiary being so distributed that all the queens are utilized to the best possible advantage. (5) When the honey flow begins the colonies are ready for the supers without additional manipulation, such as removing extra brood chambers, sorting combs of brood, etc. In equalizing colonies combs of hatching brood with the adhering workers, _without the queen_, are usually drawn from the strongest colonies and given to colonies less strong, but _never to very weak colonies_. The weakest colonies are left until the last, then built up quickly, provided there is time enough to have all the hives well filled with brood. If this is not possible the very weak colonies can more profitably be used for purposes other than comb-honey production. Another plan of equalizing is that of shaking bees from combs taken from strong colonies at the entrance of colonies less strong. The older bees at once take wing and return to their hives, while the younger bees enter the weaker colony. The operator must, of course, be sure that the queen is not on the comb thus shaken. Some of the advantages of building up the colonies as individuals are: (1) The labor required is considerably less, fewer visits being required, so that this method is particularly adapted to out-apiary conditions. (2) It is possible to determine with much greater accuracy which colonies show the most desirable traits for breeding purposes. (3) It can be more safely practiced if brood diseases are imminent. =SUMMARY.= (1) The workers that take part in storing a crop of honey from any given honey flow are usually those reared within the period of six or eight weeks just preceding the honey flow. The workers reared previous to this period are too old to be of much value as gatherers while those reared after this period mature after the flow has ceased.
