 angry, into a thick plank. . When in a rage it grinds them 

 together, and, rubbing its long beard in a most curious way, 

 leaps about in every direction. At the slightest cause of

 is from three to five inches long. Its legs are covered with 

 rough hair, and its fingers are unusually long and slender,
