Llama—L.

I refer here to the true llama or domesticated form of the genus Llama, of which the vicunha and huanaco are the existing wild species. In the stirring time when a handful of Spanish Conquistadores under Pizarro conquered and trampled upon the ancient civilisa­tion of the Incas this useful animal was employed to an immense extent as a beast of burden. Lydekker says that at the time of the Conquest of Peru it was estimated that three hundred thousand llamas were employed in the mines of Potosi alone. Prescott gives an excellent account of the use of this animal in his Conquest of Peru. They were valued highly for their strength and sureness of foot which were much needed in their long and rugged journeys over the great passes of the Cordilleras, as well as for the excellence of their flesh.

The only region of a llama’s body which is of interest in the present inquiry is the fore-foot, figured in Fig. 47. It presents a very remarkable arrangement of hair on its under surface, just above the double hoof and spongy pad at the joint above the hoof. This is found on each side towards the outer border of the hollow region, and consists of a whorl from which the hairs radiate in a reversed direction towards the upper part and transversely across the rest of the hollow. Prescott speaks of “its spongy hoof, armed with a claw or pointed talon to enable it to secure hold on the ice,” and adds that “it never requires to be shod.” If one reflects upon the ceaseless action during rough and slippery locomo­tion of this animal throughout its working life on mountain passes, on rough stony paths and ice-covered places, one can have no doubt of the reason why this particular joint, so greatly used in maintaining a foothold, should have acquired on this sheltered portion of its hair an animal pedometer.
