"'Don't you recollect how you danced with the mermaids?' he asked.
"'I don't know what you mean,' said the bride. 'I think that you must have dreamed a strange dream last night.'
"If I show you your seal skin, you'll probably believe me!' laughed the fisherman, promptly turning the boat toward the islet. They stepped ashore and he brought the seal skin out from under the stone where he had hidden it.
"But the instant the bride set eyes on the seal skin she grasped it and drew it over her head. It snuggled close to her—as if there was life in it—and immediately she threw herself into the stream.
"The bridegroom saw her swim away and plunged into the water after her; but he could not catch up to her. When he saw that he couldn't stop her in any other way, in his grief he seized his spear and hurled it. He aimed better than he had intended, for the poor mermaid gave a piercing shriek and disappeared in the depths.
"The fisherman stood on the strand waiting for her to appear again. He observed that the water around him began to take on a soft sheen, a beauty that he had never seen before. It shimmered in pink and white, like the colour-play on the inside of sea shells.
"As the glittering water lapped the shores, the fisherman thought that they too were transformed. They began to blossom and waft their perfumes. A soft sheen spread over them and they also took on a beauty which they had never possessed before.
"He understood how all this had come to pass. For it is thus with mermaids: one who beholds them must needs find them more beautiful than any one else, and the mermaid's blood being mixed with the water that bathed the shores, her beauty was transferred to both. All who saw them must love them and yearn for them. This was their legacy from the mermaid."
When the stately old gentleman had got thus far in his narrative he turned to Clement and looked at him. Clement nodded reverently but made no comment, as he did not wish to cause a break in the story.
"Now you must bear this in mind, Clement," the old gentleman continued, with a roguish glint in his eyes. "From that time on people emigrated to the islands. At first only fishermen and peasants settled there, but others, too, were attracted to them. One day the king and his earl sailed up the stream. They started at once to talk of these islands, having observed they were so situated that every vessel that sailed toward Lake Mälar had to pass them. The earl suggested that there ought to be a lock put on the channel which could be opened or closed at will, to let in merchant vessels and shut out pirates.
