The difference in size ascribed to the race, though one of the most remarkable features in the superstition, and lying on its surface, has been taken little notice of by writers. At one time the elves are small enough to creep through key-holes, and a single potato is as much as one of them can carry; at another they resemble mankind, with whom they form alliances, and to whom they hire themselves as servants; while some are even said to be above the size of mortals, gigantic hags, in whose lap mortal women are mere infants. In the Highlands the names _sithche_ and _daoine sìth_ are given to all these different sizes alike, little men, elfin youth, elfin dame, and elfin hag, all of whom are not mythical beings of different classes or kinds, but one and the same race, having the same characteristics and dress, living on the same food, staying in the same dwellings, associated in the same actions, and kept away by the same means. The easiest solution of the anomaly is that the fairies had the power of making themselves large or small at pleasure. There is no popular tale, however, which represents them as exercising such a power, nor is it conformable to the rest of their characteristics that it should be ascribed to them. The true belief is that the Fairies are a small race, the men ‘about four feet or so’ in height, and the women in many cases not taller than a little girl (_cnapach caileig_). Being called ‘little,’ the exaggeration, which popular imagination loves, has diminished them till they appear as elves of different kinds. There is hardly a limit to the popular exaggeration of personal peculiarities. Og, King of Bashan, was a big man, and the Rabbis made his head tower to the regions of perpetual snow, while his feet were parched in the deserts of Arabia. Finmac Coul was reputed strong, at least he thrashed the devil, and made him howl. A weaver in Perthshire, known as ‘the weaver with the nose’ (_figheadair na eròine_), had a big nose, at least he carried his loom in it. Similarly the ‘little men’ came down to the ‘size of half an ell,’ and even the height of a quart bottle. The same peculiarity exists in the Teutonic belief. At times the elf is a dwarfish being that enters through key-holes and window-slits; at other times a great tall man. In different localities the Fairies are known as Alfs, Huldra-Folk, Duergar, Trolls, Hill Folk, Little Folk, Still Folk, Pixies, etc. A difference of size, as well as of name, has led to these being described as separate beings, but they have all so much in common with the Celtic Fairies that we must conclude they were originally the same.
