"A flock of llamas journeying over the table-lands," says Dr. Von Tschudi, "is a beautiful sight. They proceed at a slow and measured pace, gazing eagerly around on every side. When any strange object scares them, the flock separates, and disperses in various directions, and the arrieros have no little difficulty in re-assembling them. The Indians are very fond of these animals. They adorn them by tying bows of ribbons to their ears, and hanging bells round their necks; and before loading, they always fondle and caress them affectionately. If, during a journey, one of the llamas is fatigued and lies down, the arriero kneels beside the animal, and addresses to it the most coaxing and endearing expressions. But notwithstanding all the care and attention bestowed on them, many llamas perish on every journey to the coast, as they are not able to bear the warm climate." When resting they make a peculiar humming noise, which, if it proceed from a numerous flock and is heard at some distance, resembles a concert of Æolian harps. The flesh of the llama is spongy, and not agreeable in flavour: Its wool is used in manufacturing coarse cloths. The Alpaca (_Auchenia_), or Paco, is smaller than the llama. It measures only three feet three inches from the lower part of the hoof to the top of the head, and to the shoulders two feet and a half. In form it resembles the sheep, but has a longer neck and a more graceful head. Its fleece is very long, in some parts four or five inches, and exquisitely soft. Its colour is usually either white or black, but in some few instances is speckled. Of its wool the Indians weave their blankets. It is also exported to Europe, and especially to England, in large quantities, though since the alpaca was naturalized in Australia, through the patriotic exertions of Mr. Ledger, England has begun to obtain a supply from her great and thriving colony.[133] The alpacas are kept in large flocks, which graze, throughout the year, on the green and level heights, and are driven to the huts only at shearing-time. Their shyness is very great, and at the approach of a stranger they take to rapid flight. Their obstinacy is remarkable. If one of these animals should be separated from the flock he will throw himself on the ground, and neither force nor persuasion will induce him to rise; he will frequently suffer the severest punishment rather than go the way his driver wishes. Few animals seem to stand in such urgent need of the companionship of their species, and it is only when brought to the Indian huts very young that they can be separated from their flocks.
