94 ZOOLOGICAL SKETCHES. 



This grunt and a feeble, parrying movement of his 

 fore-legs seem to be his only means of self-defence, — 

 a dertiier ressort, reserved for emergencies. If a dog 

 bites him, or if you offer him a tidbit after a prolonged 

 fast and snatch it away from his very jaws, he will slowly

 hive. I do not know if a sloth can be teased into active 

 resistance, for, after trying all my conscience and Mr. 

 Bergh would permit, that point still remains undecided. 

 A Spanish-American sportsman, however, told me that 

 the females sometimes use their claws in defence of their 

 young. This would seem to prove that not resentment 

 or even self-preservation, but child-love and the love of 

 freedom are either the most radical or the most inalien-

 long claws in entomological pursuits. On principle 

 rather than from absolute helplessness he appears to 

 surrender at discretion to all his enemies, great or small. 

 I do believe that a swarm of horse-ants could eat him 

 alive without meeting with any serious objection on his
