 cavies which range in size from that of a mouse to that of a good-

 habitats. Some kinds live in the mountains hidden among the 

 rocks by day and coming out in the twilight to feed upon tender 

 herbs and grass. Oth-

 occasional loss of a 

 member or two to a 

 beast of prey or to 

 man. The loss is 

 soon made up if the 

 food holds out, for 

 they multiply with 

 great rapidity.
