well or hole, as the cas3 may be, and, rapidly and dexterously 

 taking their fill, they make their exit in a different direction, if 

 possible, from that by which they entered ; in the meanwhile, 

 the outsiders gradually and evenly approach, and the ring is 

 gradually narrowed by a steady progressive movement of the 

 whole. A batch of fresh-comers never attempt to force their 

 way amongst those which have previously arrived, but remain 

 quietly on the outside of the ring until their turn comes. This 

 Guinea-Fowl feeds on grass, seeds, and insects, but chiefly on 

 a small bulb, which is also eagerly sought for by all the galli- 

 naceous birds. They rest during the heat of the day under 

 some mimosa, resuming their wanderings when the greatest 

 heat is passed. A flock of these birds is in general easily 

 discovered by their sharp, discordant, and metallic cries, some- 

 thing like a rapid succession of blows struck upon iron. They 

 have many enemies, and seek security at night by roosting in 

 tall mimosas.
