Those that build in trees, or erect pyramids, have a strong resemblance to each other, and pass through the same stages to the winged state, but they are not of so large a size as the foregoing; and it is a very singular circumstance, that of all these different species, neither the labourers nor soldiers expose themselves to the open air, but travel in subterraneous vaults, unless when they are obstructed and impelled by necessity; and when their covered ways and habitations are destroyed, it is wonderful how quickly they will rebuild them.  I have frequently destroyed them in the evening, and have found them re-erected on the following morning.

When a pair, in the perfect state, is rescued from the general devastation which attends these little animals, they are by the two first species elected king and queen, and are inclosed in a chamber, as before described, around which a new empire is formed, and pyramids are erected.

That species which builds in trees, frequently establish their abode in houses also, which in time they will entirely destroy, if not extirpated.  The large kind, however, are more destructive, and more difficult to guard against, as their approaches are principally made under-ground, and below the foundation; they rise either in the floors, or under the posts, which in African buildings support the roof, and as they proceed, they form cavities towards the top, similar to the holes bored in the bottom of ships by the worms, which appear to answer the same purpose in water as the termites do upon land.  How convincing is this fact of the infinitely wise arrangements of the Creator, who has united, in the whole system of creation, one uniform conformation of order and utility; for although the vermis, or worm, which is so pernicious to shipping in tropical climates, and the termite, possess so many destructive qualities, yet these very properties serve the most important purposes and designs.  Scarcely any thing perishable on land escapes the termite, or in water, the worm; and it is from thence evident, that these animals are designed by nature to rid both of incumbrances, which in tropical climates would be attended with putrefaction and disease.

The first object which strikes the attention, and excites admiration, upon opening and investigating the hills of the termites, is, the conduct of the armed species, or soldiers; when a breach is made by a pick-axe, or hoe, they instantaneously sally forth in small parties round the breach, as if to oppose the enemy, or to examine the nature of the attack, and the numbers increase to an incredible degree as long as it continues; parties frequently return as if to give the alarm to the whole community, and then rush forth again with astonishing fury.  At this period they are replete with rage, and make a noise which is very distinguishable, and is similar to the ticking of a watch; if any object now comes in contact
