Besides what we find in the recorded Fairy-Faith, there are very many parallel traditions, both Celtic and non-Celtic, about various classes of spirits, like leprechauns or other small elvish beings, which Dr. Tylor has called nature-spirits;[131] and apparently all of these can best be accounted for by means of the animistic hypothesis. For example, in North America (as in Celtic lands) there is no proof of there ever having been an actual dwarf race, but Lewis and Clark, in their _Travels to the Source of the Missouri River_, found among the Sioux a tradition that a hill near the Whitestone River, which the Red Men called the 'Mountain of Little People' or 'Little Spirits', was inhabited by pygmy demons in human form, about eighteen inches tall, armed with sharp arrows, and ever on the alert to kill mortals who should dare to invade their domain. So afraid were all the tribes of Red Men who lived near the mountain of these little spirits that no one of them could be induced to visit it.[132] And we may compare this American spirit-haunted hill with similar natural hills in Scotland said to be fairy knolls: one near the turning of a road from Reay Wick to Safester, Isle of Unst;[133] one the well-known fairy-haunted Tomnahurich, near Inverness;[133] and a third, the hill at Aberfoyle on which the 'people of peace' took the Rev. Robert Kirk when he profaned it by walking on it; or we may equate the American hill with the fairy-haunted Slieve Gullion and Ben Bulbin in Ireland. The Iroquois had a belief that they could summon dwarfs, who were similar nature-spirits, by knocking on a certain large stone.[134] Likewise the Polong, a Malay familiar spirit, is 'an exceedingly diminutive female figure or mannikin'.[135] East Indian nature-spirits, too, are pygmies in stature.[136] In Polynesia, entirely independent of the common legends about wild races of pygmy stature, are myths about the spirits called _wui_ or _vui_, who correspond to European dwarfs and trolls. These little spirits seem to occupy the same position toward the Melanesian gods or culture heroes, Qat of the Banks Islands and Tagaro of the New Hebrides, as daemons toward Greek gods, or as good angels toward the Christian Trinity, or as fairy tribes toward the Brythonic Arthur and toward the Gaelic hero Cuchulainn.[137] Similarly in Hindu mythology pygmies hold an important place, being sculptured on most temples in company with the gods; e. g. Siva is accompanied by a bodyguard of dwarfs, and one of them, the three-legged Bhringi, is a good dancer[138]--like all _corrigans_, pixies, and most fairies.
