gration, which results in the wider distribution and in the 
increase of the number of the species. It is a peculiar but 
effective mode of distributing and perpetuating the species. 
There are many other interesting and suggestive things 
which might be told of the life in a bee community: how 
the community protects itself from the dangers of starva- 
tion when food is scarce or winter comes on by killing the 
useless drones and the immature bees in egg and larval 
stage; how the instinct of home-finding has been so highly 
developed that the worker bees go miles away for honey 
and nectar, flying with unerring accuracy back to the hive; 
of the extraordinarily nice structural modifications which 
adapt the bee so perfectly for its complex and varied busi- 
nesses ; and of the tireless persistence of the workers until
