But the veritable Pixydom lies south of the Tamar. In Cornwall, that stretch of deserted moors furrowed on either side by little river-valleys, that rocky promontory which seems to belong more to the kingdom of the sea than to England, the Celtic imagination has rioted at will. There were giants in the land in bygone days, for the wanderer among those strangely sculptured crags of granite, slate, and serpentine chances at every turn on a Giant's Cradle or a Giant's Chair, Giant's Spoon, Giant's Bowl, Giant's Key, Giant's Hat, Giant's Table, Giant's Well, Giant's Pulpit, Giant's Grave. Cornishmen have heard the music and seen the fairy dances, spied on fairy banquets, and peeped in on fairy funerals. The Small People have been gay and kindly neighbours, sometimes whisking away a neglected baby and returning the little mortal all pink and clean, wrapped in leaves and blossoms, "as sweet as a nut." These are the spirits of Druids, or of other early Cornwall folk, who, as heathen, may not go to heaven, but are too innocent for hell. So they are suffered to live on in their old happy haunts, but ever dwindling and dwindling, till it is to be feared that bye and bye, what with all the children growing stupid over schoolbooks, and all the poets writing realistic novels, the Small People will twinkle out of sight. The Spriggans, lurking about the cairns and cromlechs, where they keep guard over buried treasures, could better be spared. They are such thievish and mischievous trolls, with such extraordinary strength in their ugly bits of bodies, it is more likely they are the diminished ghosts of the old giants. The Piskies are nearly as bad, as any bewildered traveller who has been Pisky-led into a bog would testify. The only sure protection against their tricks is to wear your garments inside out. Many a Cornish farmer has found a fine young horse all sweated and spent in the morning, his mane knotted into fairy stirrups showing plainly how some score of the Piskies had been riding him over night. And many a Cornish miner, deep down in the earth, has felt his hair rise on his head as he heard the _tap_, _tap_, _tap_ of the Knockers, souls of long-imprisoned Jews sent here by Roman emperors to work the tin-mines of Cornwall. The Brownies, who used to be so helpful about the house, have grown shy of late and can be depended on for assistance only when the bees are swarming. Then the housewife beats on a tin pan, calling at the top of her voice: "Brownie! Brownie!" till she sees that he has heard her and is persuading the bees to settle. Offended mermaids have choked up Cornish harbours and buried sea-coast villages under sand. If you doubt it, go and look at the little church of St. Piran--the miners' saint, who came sailing from Ireland on a millstone and discovered the Cornish tin--the church that for seven centuries was hidden under the sands and then, as the restless winds sifted and searched them, rose again to human sight.
