 in places where the hoof of the mule could find no support. 

 It was estimated, after the conquest, that 300,000 were thus 

 employed. As they never feed after sunset, it is necessary, 

 when journeying, to allow them to graze for several hours dur- 

 ing the day. They utter a peculiar low sound, which at a dis- 

 tance resembles, when the herd is large, the tone of numer-

 killed for food.

The alpaca is smaller than the llama, and somewhat re- 

 sembles the sheep. It has a long, soft, fine fleece of a silky
