Of the Strange People not much is known, even at Mio, though it is sure they come there. It seems they are shy indeed, more’s the pity. They come through the blue air, or across the mysterious paths of the sea. Their footprints are never, never seen upon the wet beach, for they tread too lightly. But sometimes in their dancing they sweep their robes upon the sand and leave it ribbed and ruffled; so, often enough, it may be seen at Mio.
