SECOND\RY SWARMS, 229 
leave, after hiving, than primary-swarms. It is probably 
owing to the fact that the young queen has to go out for 
her bridal trip (121), and the bees sometimes leave with 
her. Acomb of unsealed brood (166) given them will 
usually prevent this (109). An absconding swarm often 
leaves without settling. 
449. After the departure of the second swarm, the oldest 
remaining queen leaves her cell; and if another swarm is 
to come forth, piping will still be heard; and so before the 
issue of each swarm after the first. It will sometimes be 
heard for a short time after the issue of the second swarm, 
even when the bees do not intend to swarm again. The third 
swarm usually leaves the hive on the second or third day 
after the second swarm, and the others, at intervals of 
about a day. We once had five swarms from one stock, 
in less than two weeks. In warm latitudes, more than 
twice this number of swarms lave been known to issue, in 
one season, from a single stock. 
After-swarms, or casts—these names are given to all 
swarms after the first—seriously reduce the strength of the 
parent-stock; since by the time they issue, nearly all the 
brood left by the old queen has hatched, and no more eggs 
can be laid until all swarming is over. If, after swarming, 
the weather suddenly becomes chilly, and the hive is thin, 
or the Apiarist continues the ventilation which was needed 
only for a crowded colony, the remaining bees being unable 
to maintain the requisite heat, great numbers of the brood 
may perish. 
PREVENTION OF NATURAL SWARMING. 
450. The prevention of natural swarming, in the pres- 
ent state of bee-keeping, is an important item, for several 
reasons. 
Ist, Bee-keeping has so spread in the last few years, that
