_Alux_ they call certain apparitions which they believe to exist in the ancient ruins and on the hills, and they say that as soon as it grows dark in the evening these apparitions or ghosts commence to walk around the houses, throwing stones, whistling to the dogs and lashing them when they get near them, which leaves the poor beasts with a cough that kills them. They pretend that these ghosts can run with great speed, as well backward as forward; that they do not terrify those who look at them. They are wont to enter into the houses to annoy and tease people who are abed in their hammocks, not letting them sleep. They assure us that on ranches where sugar-cane is grown, and just as soon as the grinding machine for the cane is set up, they will go and turn it or they will drive on the horse attached to it, to make it trot around. They say these apparitions are of the size of a little Indian boy of four or five, and that they appear naked, with only a little hat on their heads. This belief is the cause of incalculable loss to antiquarians on account of the almost daily destruction of articles found in the ruins. The Indians will destroy without pity or regard, notwithstanding they may be offered a good price for them, all the images in clay and other objects found on the hills or in subterranean passages, because they are convinced that these objects are the ones that become alive at night and come out to walk around. They attribute to the _alux_ or to their influence, all the diseases they have, as they consider their touch malignant. They say that if these apparitions find anyone asleep they will pass their hands over his face so lightly that the sleeper does not even feel it, but this causes him a fever which incapacitates him for a long time.
