Such a "sheean" is the Denghoog in the Danish island of Sylt, one of the mounds believed to have been the residence of Finn, the dwarf king. Mr. W. G. Black, who has visited this "how," describes it thus:[189]

"Externally merely a swelling green mound, like so many others in Sylt, entrance is gained by a trap-door in the roof, and descending a steep ladder, one finds himself in a subterranean chamber some seventeen by ten feet in size, the walls of which are twelve huge blocks of Swedish granite; the height of the roof varies from five feet to six feet. The original entrance appears to have been a long narrow passage seventeen feet long and about two feet wide and high. This mound was examined by a Hamburg professor in 1868, who found remains of a fire-place, bones of a small man, some clay urns, and stone weapons."

This example, then, of the abode of one of the "Feens of Lochlan," corresponds exactly with Maes-how and all similar "sheeans." And, like them, it is locally remembered as the residence of a dwarf.

This, of course, is tradition. But the northern sagas (though "tradition" also) are accepted as "history," in some degree. And the sagas bear a like record. Their heroes break into those dwellings, make their entrance by the hole at the bottom of the "crater," and attack the inhabitants, who, seizing their weapons, defend their lives and (in many cases) their treasures. And before leaving the "hollow hill" of Maes-how, it may be stated that this particular broch, or sheean, is believed to have been invaded about a thousand years ago. It was entered in the twelfth century by some of those North-men who were on their way to the Holy Land; and these have incised various inscriptions on its inner walls. But at that date it was empty—and had been rifled many centuries before. One legendary tale places the date of its original despoliation as far back as the year 920; and states that "Olaf the Norseman" was its invader; and that he encountered its possessor, whom he overcame—after a deadly struggle. And, since "the common tradition of the country [up to the year 1861, when it was reopened] represented it as the abode of a goblin, who was named 'the Hog-boy'," it would seem that the prevailing blood of the country-people in that district is akin to that of this "Olaf the Norseman;" and that, therefore, in this instance, the popular memory reaches back for nearly a thousand years, with the most perfect precision.[190]

The Ross-shire Tombuidhe, the Sylt Denghoog; and this Orcadian broch are all specimens of the one class; and, both as regards the character of the dwellers and the dwellings, they have many counterparts. How many we do not yet know. It is probable that, in the British Islands alone, they may be numbered by thousands (and we need not here speculate as to the continent of Europe, and other parts of the globe). Colonel Forbes Leslie, referring only to Scotland, says that "even in the present day many a green mound ... is shunned by sturdy peasants who would not fear the hostility of any mortal"—and this because that mound once contained one or more people of a race of whom that peasant's ancestors stood greatly in awe. That the valleys of the Forth and Teith alone contain a great number of those "green hillocks," as yet unexamined, has been stated by an eminent investigator of the Scotch brochs, Dr. Joseph Anderson. How many other districts can tell a similar story is a problem that will some day be solved.

The collector (who is, to a great extent, the exponent also) of the "Popular Tales of the West Highlands," appends several very interesting remarks to one of these stories: that of "The Smith and the Fairies" (vol. ii. pp. 46-[55]). Among other things he says: "The belief that the 'hill' opened on a certain night, and that a light shone from the inside, where little people might be seen dancing, was too deeply grounded some years ago to be lightly spoken of; ... 'In the glebe of Kilbrandon in Lorn is a hill called Crocan Corr ... where the fairies ... were often seen dancing around their fire.'" And reference is also made to "a certain hill in Muckairn, known to be the residence of the fairies." The incident connected with it is capped with a similar one "told of a hill called Ben-cnock in Islay;" and "another hill, called Cnock-doun" (presumably in Islay), has a like history. But such "hills" are too numerous to mention in detail.

Owing to the great mass of earth which was heaped over the dwelling—the actual "kernel" of the mound—it will be seen that new-comers of another race from the mound-dwellers might build houses, or bury their dead, above the homes of the "little people," without being aware that the hill they were so utilizing was entirely of artificial origin. Nor are there wanting illustrations of this in fact and in tradition. Legendary lore, indeed, is full of incidents arising from the contact, often unexpected on the one side, of the two races; and many such tales reveal the mound-dwellers in a very homely light. The following story from the Hebridean island of Barra, for example:

"There was a woman in Baile Thangasdail, and she was out seeking a couple of calves; and the night and lateness caught her, and there came rain and tempest, and she was seeking shelter. She went to a knoll with the couple of calves, and she was striking the tether-peg into it. The knoll opened. She heard a gleegashing as if a pot-hook were clashing beside a pot. She took wonder, and she stopped striking the tether-peg. A woman put out her head and all above her middle, and she said, 'What business hast thou to be troubling this tulman in which I make my dwelling?' 'I am taking care of this couple of calves, and I am but weak. Where shall I go with them?' 'Thou shalt go with them to that breast down yonder. Thou wilt see a tuft of grass. If thy couple of calves eat that tuft of grass, thou wilt not be a day without a milk cow as long as thou art alive, because thou hast taken my counsel.'"[191]
