(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.=
