[Footnote 62: George Webbe Dasent says (_Pop. Tales_, Introd., pp. 57-58): "The trolls, or, the other hand [i.e., in comparison with the Giants], with whom mankind had more to do, were supposed to be less easy tempered, and more systematically malignant, than the Giants, and with the term were bound up notions of sorcery and unholy power.... But when Christianity came in, and heathendom fell; when the godlike race of Æsir became evil demons instead of good genial powers, then all the objects of the old popular belief, whether Æsir, Giants, or Trolls, were mingled together in one superstition, as 'no canny.' They were all trolls; all malignant; and thus it is that, in these tales, the traditions about Odin and his underlings, about the Frost Giants, and about sorcerers and wizards, are confused and garbled; and all supernatural agency that plots man's ill is the work of Trolls, whether the agent be the arch enemy himself, or giant, or witch, or wizard." It is quite impossible to characterize trolls in detail with unqualified words or phrases. They are usually malignant, though there are instances of their doing men a good turn. They are always very powerful, and are usually very large. It is told of one troll that, had she not made a misstep, she would have succeeded in wading from Norway to Iceland; and of another, that the thumb of his glove held four bushels, good measure. In some instances, however, it is possible for many trolls to enter one room of an ordinary dwelling house. There are trolls with three heads, with six heads, with nine heads, and with twelve heads. Sometimes they are one-eyed, and sometimes they have other characteristics that differentiate them from human beings. In fact, anything with supernatural qualities is apt to be called a troll. As a rule, it is impossible for human beings to cope with trolls except by outwitting them, which often is done. They are inimical to Christianity; and, though their depredations may occur on any day of the year, between sunset and sunrise, adventures with trolls, as stated above, are frequently represented as occurring Christmas Eve; and that is the time when particular precaution must be taken to avoid them. Usually it is taken for granted that trolls will not attack the inmates of a house, and people feel perfectly safe so long as they do not venture out. In another type of troll story, however, people expect trolls to invade the house Christmas Eve and attack them; and to avoid injury, the inmates vacate the house for the night, before sunset. Illustrations of these statements are found in such well known collections of fairy tales as _Sc. Folkl._, _Nor. Tales_, _Folk. Huld. Even._, _Event. Sagn_.] [Footnote 63: This story is in print and was related to the present writer by one who had read it; and, though diligent search has failed to locate it again, the writer ventures to reproduce it, for he is certain that it is in existence.]
