Anatomy of the Bee.

with pollen and honey often mount guard, and 
by a constant beating of their wings help to 
purify the air of the hive. 
2. In artificial swarms it is a remarkable fact 
that, on the days following the removal of the 
upper story of the hive, which is then placed at 
some distance from its previous position, all the 
bees in the hive work at the development of 
the brood ; and it is not until after the hatching 
takes place, and the colony is thus reinforced, 
that the work out of doors recommences. 
3. If there were bees exclusively employed in 
working the wax, during a great part of the 
spring there would be no work for them in a 
hive well stocked with comb — a fact which 
cannot be allowed, knowing their zeal and im- 
mense activity. 
4. Lastly, worker bees are all formed so as to 
fulfil all these functions ; and it is worth notice 
that certain hives, in summer, after receiving a 
great number of bees laden with pollen in the 
morning, receive hardly any in the afternoon, 
and even at what is considered to be the best 
gathering time, very few bees are loaded with 
pollen. Still, we allow that the young bees are 
exclusively occupied with the internal work of
