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.
The largest animal of this tribe is the Huanacu or Guanaco. He measures five feet from the bottom of the hoof to the top of the head, and three feet three inches to the shoulders. So nearly does he resemble the llama in form that, until very recently, zoologists supposed the latter to be an improved species of the huanacu, and that the huanacu was neither more nor less than a wild llama. But there are specific differences between them. The huanacu is of a uniform reddish-brown colour on the neck, back, and thighs. The under part of the body, the middle line of the breast, and the inner side of the limbs are of a dingy white. The wool is shorter and coarser than that of the llama, and of nearly uniform length on all parts of the body. The huanacus assemble in small herds of five or seven, and if taken very young may be tamed, but can with difficulty be trained as beasts of burden.
The Vicuña is a more beautiful animal than either of the preceding. His size is a medium between that of the llama and alpaca. He measures four feet one inch to the top of the head, and two feet six inches to the top of the shoulders. He is distinguished by his longer and shapelier neck, by the superior fineness of his short curly wool. The crown of the head, the upper part of the neck, the back, and thighs are of a peculiar reddish-yellow hue, which the natives call color de vicuña. The lower part of the neck and the inner parts of the limbs are of a bright ochreous colour, and the breast and lower part of the body white.
During the wet season the vicuña browses on the scanty vegetation of the Cordilleran ridges. He never ventures up to the bare rocky summits, for his hoofs, being accustomed only to the yielding sward, are very soft and tender. He lives in herds, consisting of from six to fifteen females, and one male, who is the protector and leader of the herd, and who, while the females graze, stands a few paces apart, carefully watching over their safety. At the approach of danger he gives a signal, consisting of a kind of whistling sound and a quick movement of the foot. Immediately the herd draws close together, each animal stretching out his head in the direction of the impending alarm. Then they take to flight; first moving leisurely and cautiously, but quickening their pace to the utmost degree of speed; whilst the male vicuña, who covers the retreat, occasionally halts to observe the motions of the enemy. The females reward his devotion by the warmest affection and fidelity, and will suffer themselves to be killed or captured rather than desert him.
The mode in which the Indians hunt the vicuña is sufficiently curious. In the Chacu, as it is termed, the whole company, seventy or eighty in number, proceed to the Attos—the most secluded districts of the Peruvian mountains—which are the animal’s favourite haunts, with an abundant supply of rope and cord, and numerous stakes. Selecting a spacious open area, they drive the stakes into the ground in a circle, at intervals of from twelve to fifteen feet apart, and connect them together by ropes fastened at the height of two or two and a half feet from the ground. The circular space within this enclosure measures about half a league in circumference; an opening of about two hundred paces in width is left for entrance. On the ropes which are carried round the stakes, the Indian women hang pieces of coloured rag that flutter gaily in the wind.
The chacu being thus made ready, the Indians, who are mounted on horseback, range over the country within a circuit of several miles, driving before them all the herds of vicuñas they encounter, and forcing them into the chacu. When a sufficient number is collected, they close the entrance. The timid animals do not attempt to leap over the ropes, being affrighted by the fluttering rags, and when thus secured, the Indians easily kill them with their bolas.
These bolas consist of three balls, composed either of lead or stone; two of them heavier than the third. They are fastened to long elastic strings, made of twisted sinews of the vicuña, and the opposite ends of the strings are all tied together. The Indian holds the lightest of the three balls in his hand, and swings the two others in a wide circle above his head; then, taking his aim at the distance of about fifteen or twenty paces, he lets go the hand-ball, whereupon all three whirl in a circle, and cling round the object aimed at. The aim is usually directed at the animal’s hind legs, and the cords twisting round them, he is unable to move. Great skill and long practice are required to throw the bolas dexterously; a novice in the art incurs the risk of dangerously hurting either himself or his horse, by not giving the balls the proper swing, or by letting go the hand-ball too soon.
