 When an inundation takes place, they are heaped toge-

 diameter and four fingers in depth. Thus they remain 

 floating upon the water while the inundation continues. 

 One of the sides of the mass which they form is attached 

 to some sprig of grass, or piece of wood ; and when the 

 waters are retired, tl^ey return to their habitation. When 

 they wish to pass from one plant to another, they may

 and of the breadth of a finger, which has no other sup- 

 port than that of its two extremities. One would sup- 

 pose that their own weight would sink them ; but it is

Gould tells us that the hill-ant is very fond of basking 

 in the sun, and that on a fine serene morning you may 

 see them conglomerated like bees on the surface of their 

 nest, from whence, on the least disturbance, they will 

 disappear in an instant b . M. Huber also observes, after 

 their labours are finished, that they stretch themselves 

 in the sun, where they lie heaped one upon another, and 

 seem to enjoy a short interval of repose : and in the in- 

 terior of an artificial nest, in which he had confined some
