The attitude of the fairies towards mankind was, generally speaking, kindly and helpful, so much so that by the country people they were often termed the "good neighbours" and the "wee fouk"; but underneath all their display of nobility, an elfin craftiness and capriciousness of disposition existed, malignant to a degree. They did not, for example, ride unarmed, but had bows and arrows of peculiar power and potency slung at their sides ready to assail the too curious human being or menacing beast. The bows themselves were fashioned from the ribs of men buried "where three Lairds' lands meet," and the arrows, which hung in quivers made from adders' sloughs, were "tipped with deadly plagues." When mortals offended, it was on their cattle the fairies usually wreaked their vengeance by shooting them with their magic bows and arrows. Such elf-shot cattle exhibited all the symptoms of malignant cramp. Animals quite as innocent, but who, blunderingly unconscious, threatened to trample their diminutive bodies under foot as they passed along, were as summarily treated--at least that was a common explanation to account for puzzling forms of cattle-ill; for the wound of the true elf arrow was so small that evidence of penetration was almost impossible of vision, unless by the eye of those favoured and deeply skilled in fairy-craft practice. A less vague and more material description of the fairy arrows was, that "these fatal shafts were formed of the bog reed, pointed with white field flint, and dipped in the dew of hemlock." To this day the triangular flints of the Stone Age are associated with the fairy superstition, being popularly known as "elf bolts," and the occasional turning up of these flints on cultivated land, finds a superstitious explanation in the belief that a shower of these arrows discharged into a field was quite sufficient to blast and wither the expected crop. The special characteristic of the evil element in the disposition of the fairies was however, a persistent practice of kidnapping unchristened infants, substituting for them baby imps of their own, which in old-world phraseology were known as "changelings." Such changelings could only be detected and expelled by certain charms and mystic practice, which also permitted the real babe to be restored. The explanation of such kidnapping was that every seventh year "Kain," in the form of a living sacrifice from the ranks of the fairies, was demanded by Satan, their master, as the price of the supernatural privileges they enjoyed, but as a mortal infant was as readily accepted, the fairies naturally acted in accordance, much preferring to lay a human babe at the feet of the Evil One.
