trees, earth, clay, etc., etc., are made use 
of, while the outward form or structure 
likewise varies. Frequently there is a 
considerable-sized mound or “ant hill”; 
at other times a small one, in which the 
intricate parts are below the level of the 
ground. Sometimes an old tree is made 
use of, or a wall or the roof of a dwelling- 
place. If these nests are cut into sectionally, 
it will often be discovered that the interior 
varies between one nest and another quite 
as much as do the externals. Apparently 
the aim and object of all is the same, viz., 
the protection of the larvae from climatic 
and other risks. The interior shows a 
number of stories connected by corridors, 
and the hard-working neuters may be seen 
inside just as we see them outside, when 
disturbed, carrying the precious larvae 
from place to place. When the sun’s rays 
are pouring upon the nest the larvae are 
brought near to the surface that they may 
get the benefit of the warmth. When it 
becomes colder these are removed to a lower 
story. These inner recesses are also used 
when there is danger from an outside 
enemy.
