A Conjecture
Some writers have ventured a conjecture that the dwarfs so often mentioned in the ancient sagas and fairy-tales were real beings, probably the Phœnician miners, who, working the coal, iron, copper, gold, and tin mines of England, Norway, Sweden, etc., took advantage of the simplicity and credulity of the early inhabitants to make them believe that they belonged to a supernatural race and always dwelt underground, in a region which was called Svart-alfa-heim, or the home of the black elves.
