The road from Alfheim to Svartheim is not as long as you would be apt to imagine. Indeed, it is possible for a careless person to wander from one region to another without being at once aware of it. Skirnir, having the key in his hand, took the direct way. The entrance-gate stands at the opening of a dim mountain-cave. Skirnir left his horse without, and entered; the air was heavy, moist, and warm, and it required the keenest glances of Skirnir's keen eyes to see his way. Innumerable narrow, winding paths, all leading downwards, opened themselves before him. As he followed the widest, a faint clinking sound of hammers met his ear, and, looking round, he saw groups of little men at work on every side. Some were wheeling small wheelbarrows full of lumps of shining metal along the ledges of the rock; some, with elfin pickaxes and spades, were digging ore from the mountain-side; some, herded together in little caves, were busy kindling fires, or working with tiny hammers on small anvils. As he continued his downward path the last remnant of daylight faded away; but he was not in total darkness, for now he perceived that each worker carried on his head a lantern, in which burned a pale, dancing light. Skirnir knew that each light was a Will-o'-the-wisp, which the dwarf who carried it had caught and imprisoned to light him in his work during the day, and which he must restore to the earth at night. For many miles Skirnir wandered on lower and lower. On every side of him lay countless heaps of treasure--gold, silver, diamonds, rubies, emeralds--which the cunning workers stowed away silently in their dark hiding-places. At length he came to the very middle of the mountain, where the rocky roof rose to an immense height, and where he found himself in a brilliantly-lighted palace. Here, in truth, were hung all the lights in the world, which, on dark, moonless nights, are carried out by dwarfs to deceive the eyes of men. Corpse-lights, Will-o'-the-wisps, the sparks from glow-worms' tails, the light in fire-flies' wings--these, carefully hung up in tiers round and round the hall, illuminated the palace with a cold blue light, and revealed to Skirnir's eyes the grotesque and hideous shapes of the tiny beings around him. Hump-backed, cunning-eyed, open-mouthed, they stood round, laughing, and whispering, and pointing with shrivelled fingers. One among them, a little taller than the rest, who sat on a golden seat thickly set with diamonds, appeared to be a kind of chief among them, and to him Skirnir addressed his message.
