earth, in the midst of Midgard, that middle earth which we hear of in early English poetry, the abode of gods and men. Bound that earth, which was fenced in against the attacks of ancient and inveterate foes by a natural fortification of hills, flowed the great sea in a ring, and beyond that sea was Utgard, the outlying world, the abode of Frost Giants, and Monsters, those old-natural powers who had been dispossessed by Odin and the Æsir when the new order of the universe arose, and between whom and the new gods a feud as inveterate as that cherished by the Titans against Jupiter was necessarily kept alive. It is true indeed that this feud was broken by intervals of truce during which the Æsir and the Giants visit each other, and appear on more or less friendly terms, but the true relation between them was war; pretty much as the Norseman was at war with all the rest of the world. Nor was this struggle between two rival races or powers confined to the gods in Asgard alone. Just as their ancient foes were the Giants of Frost and Snow, so between the race of men and the race of Trolls was there a perpetual feud. As the gods were men magnified and exaggerated, so were the Trolls diminished Frost Giants; far superior to man in strength and stature, but inferior to man in wit and invention. Like the Frost Giants, they inhabit the rough and rugged places of the earth, and, historically speaking, in all probability represent the old aboriginal races who retired into the mountainous fastnesses of the land, and whose strength was exaggerated, because the intercourse between the races was small. In almost every respect they stand in the same relations to men as the Frost Giants stand to the Gods.
