They are usually termed hills, and are generally in a conical form, from 10 to 12 feet in perpendicular height, and frequently upwards of 100 feet square in the base.

For a considerable period, vegetation is banished from the surface of their abode, but from the second to the third year, it becomes like the surrounding soil.  The exterior forms a crust, which shelters the interior from the weather, and the community from the attacks of enemies.  The interior is divided into almost innumerable chambers or apartments, with amazing regularity and contrivance; in the centre of which is the royal residence of the king and queen, composed of solid clay, closely compacted, and distinct from the external habitation, which accommodate their subjects.  It appears that the royal erection is the first which occupies the attention of the labourers, as it is central in the foundation of the hill which composes the empire at large.  This makes its first appearance above the surface of the earth in various turrets, in the form of a sugar loaf, from which they increase their number, widening them from the base; the middle one is the highest and largest, and they fill up the spaces as they proceed, until the whole is formed into one.

This compact construction is admirably adapted to guard against external violence, and to preserve a genial warmth and moisture to cherish the hatching of the eggs, and the young.

The queen is by far the largest, and has an unwieldy body, of enormous dimensions, when compared with her subjects; so also is the king, but inferior in size to the queen.

The royal residence is a full constructed hill, surrounded by an innumerable number of others, differing in shape and dimensions, arched in various forms, circular, and elliptical, which communicate by passages, occupied by guards and attendants, and surrounded by nurseries and magazines.  But when the community is in an infant state, these are contiguous to the royal residence; and in proportion as the size of the queen increases, her chamber is enlarged, and her attendants and apartments multiplied.

The construction of the outward apartments which surround the central royal residence, that of the common father and mother of the community, form an intricate labyrinth of nurseries and magazines, separated by chambers and galleries, communicating with each other, and continuing towards the surface of the pyramid; and being arched, they support each other, and are uniformly larger towards the centre.

The second order of termes are like the first, blind and active, but they undergo a change of form, approaching to the perfect state; they are much larger, and increase from about a quarter of an inch in length to half an inch, and greater in bulk; and what is still more remarkable, the mouth is armed with sharp claws, and the head is disproportionably enlarged.  They may properly be called the nurses and warriors of the kingdom; they urge their fellow subjects in the first state to labour, they inspect the construction of the interior apartments, repel all attacks from enemies, and devour them with fury; and may be considered as the standing army of the state.
