 haunches, when at rest, holding their food between their fore-

 valued on account of their fur, and have been largely imported. 

 This is especially the case in regard to the Chinchilla, a

 nature, little is known, save that it associates in numbers, and 

 excavates burrows in which it resides, feeding chiefly upon roots,
