We have been shown, in our two preceding pieces from Ernst Willkomm, Pathetic Fairies, and Fairies merry to rioting. Here we have, not without merriment either, Working Fairies. In the mines of the Upper Lusatian Belief, the tale of THE DWARF'S WELL strikes into a vein which our author has promised us, but of which we have not heretofore handled the ore. Here we shall see the imagination touching in some deeper sterner colours to the sketches flung forth by the fancy; and in the spirit of unreal creation, a wild self-will which rejoices to waft into the presence of the beautiful, and of unbridled laughter, cold blasts from the region of pure affright. There is in this, however, no prostration of strength--quite the reverse! Not a nervous and enfeebled sensibility, yielding itself up to a diseased taste for pain.--No child fascinated with fear, and straining its eyes to take in more horror. But here the unconquerable consciousness of strong life throws itself with an unmastered glee of battle, right into the thick of its mortal adversaries, to slay, and strip, and bind to its own triumphant chariot-wheels. The Upper Lusatian Highlander, turned poet, dreaming at his discretion, amuses himself with converting terror and madness into merriment, and reconciles conflicting elements of invention--with an overpowering harmony?--No. But, by subjugating them all alike to one imperious lord, viz. to himself;--to his own pleasure. Hence, in the Traditions and Tales, in which he embodies his illusory creed of the Invisible, there is engendered an esthetical species, which waits, perhaps, for a name with us, and might accept that of the _Ghastly_, or at least, of the _Ghostly-Humorous_, the _Gay-Horrible_. The story of the PRIEST'S WELL soars boldly upon this pinion; that of the WILL-O'-THE-WISP HUSSAR has gone stark-raving in the same grimly-mirthful temper. The mind in which Burns imagined and chaunted his TAM-O'-SHANTER, is right down Upper Lusatian, in this key. Our Elves, however, are not yet witches. The kinds of the spirits confine, upon every side, with one another, and the boundary lines vanish. Within the circumscription of the Fairy domain, an indeterminable difference appears betwixt the truest Fairies and the Dwarfs. The two sorts, or the two names, are sometimes brought into glaring opposition. Again, like factions made friends, they blend for a time indistinguishably. So, in the Persian belief, the ugly _Dios_, who may represent the Dwarfs of our west, are--under one aspect of the Fable--the implacable _cannibal_ foes--under another,--the loving spouses of the beautiful Peris. Comparing the Fairies of our two former tales, and the Dwarfs of this, the reader will probably see in THOSE, the daintier, the more delicate: in THESE, a little more hardness of nature.
