One thing was certain, however: he had inherited from his mother, whom all men agreed had been mortal, the dangerous qualities of vanity and ambition. And the longer he lived the more vain and ambitious did he become, until at last he always carried a mirror of polished steel round his neck, into which he constantly looked in order to see the reflection of his handsome face.

And he would not attend to the country people who came to seek his help, unless they bowed themselves humbly before him and spoke to him as if he were a King.

I say that the country people sought his help, for he spent his time, or appeared to spend it, in collecting herbs and simples on the hillsides, which he carried home with him to his dark abode, and distilled medicines and potions from them, which he sold to his neighbours at wondrous high prices.

He was also the possessor of a wonderful leathern-covered book, clasped with clasps of brass, over which he would pore for hours together, and out of which he would tell the simple Islanders their fortunes, if they would.

For they feared the book almost as much as they feared Snorro himself, for it was whispered that it had once belonged to Odin, and they crossed themselves for protection as they named the mighty Enchanter.

But all the time they never guessed the real reason why Snorro chose to live in the Dwarfie Stone.

I will tell you why he did so. Not very far from the Stone there was a curious hill, shaped exactly like a wart. It was known as the Wart Hill of Hoy, and men said that somewhere in the side of it was hidden a wonderful carbuncle, which, when it was found, would bestow on its finder marvellous magic gifts—Health, Wealth, and Happiness. Everything, in fact, that a human being could desire.

And the curious thing about this carbuncle was, that it was said that it could be seen at certain times, if only the people who were looking for it were at the right spot at the right moment.

Now Snorro had made up his mind that he would find this wonderful stone, so, while he pretended to spend all his time in reading his great book or distilling medicines from his herbs, he was really keeping a keen look-out during his wanderings, noting every tuft of grass or piece of rock under which it might be hidden. And at night, when everyone else was asleep, he would creep out, with pickaxe and spade, to turn over the rocks or dig over the turf, in the hope of finding the long-sought-for treasure underneath them.

He was always accompanied on these occasions by an enormous grey-headed Raven, who lived in the cave along with him, and who was his bosom friend and companion. The Islanders feared this bird of ill omen as much, perhaps, as they feared its Master; for, although they went to consult Snorro in all their difficulties and perplexities, and bought medicines and love-potions from him, they always looked upon him with a certain dread, feeling that there was something weird and uncanny about him.
