58 HISTORY OF INSECTS. 



or living thing that in any way injures or endangers the 

 safety of the nest ; this duty they perform with the most 

 reckless bravery, the labourers retiring within the nest dur- 

 ing the time of danger. The offices of the labourers are 

 manifold ; they take the eggs from the queen as fast as she 

 lays them, convey them to the nurseries, tend them until 

 hatched ; they feed the young, store provisions, build the 

 nest, repair damages, and perform every kind of labour re-

The nests of the wliite ants are so numerous all over the

 rest of the earth, almost covered with grass and other plants, 

 and in the dry season, when the herbage is burnt up by the 

 rays of the sun, somewhat resemble very large hay-cocks. 

 The exterior of the building is one large shell in the man-

 and the inhabitants from the attacks of natural or acciden-

 the interior building, which is the habitable part, divided 

 with a wonderful kind of regularity and contrivance into an 

 amazing number of apartments, for the residence of the 

 king and queen and the nursing of their numerous proge-
