habitants, in a great variety of winding 

 directions, all communicating with each 

 other, and with several other nests upon the 

 same tree. They have also another house 

 built on the ground, generally at the root of 

 a tree, formed like an irregularly sided cone ; 

 sometimes more than six feet high, and 

 nearly as much in diameter. The outside 

 of these nests is of well-tempered clay, about 

 two inches thick, and within are the cells, 

 which have no opening outward. One of 

 these is their summer, and the other then- 

 winter dwelling, communicating with each 

 other by a large avenue leading to the ground, 

 by a subterraneous passage. The ground 

 structures are proof against wet, which those 

 in the branches are not. — Encyc. Brit.
