THE IRISH POOKA WAS A HORSE TOO.
Kelpies, who were Scotch, haunted fords and ferries, especially in storms; allured bystanders into the water, or swelled the river so that it broke the roads, and overwhelmed travellers.
Very like them were the Brag, the little Shoopil-tree of the Shetland Islands, and the Nick, who was the Icelandic Nykkur-horse; gamesome deceivers all, who enticed children and others to bestride them, and who were treacherous as a quicksand, every time. And there were many more of the Kelpie kingdom, of whom we can hunt up no clews.
A man who saw a Kelpie gave himself up for lost; for he was sure, by hook or crook, to meet his death by drowning. Kelpie, familiar so far away as China, never stayed in the next-door countries, Ireland or England, long enough to be recognized. They knew nothing of him by sight, nor of the Nix his cousin, nor of anything resembling them. In Ireland lived the merrow; but she was only an amiable mermaid.
WILL-O'-THE-WISP.
The Japanese had a water-dragon called Kappa, "whose office it was to swallow bad boys who went to swim in disobedience to their parents' commands, and at improper times and places." In the River Tees was a green-haired lady named Peg Powler, and in some streams in Lancashire one christened Jenny Greenteeth; two hungry goblins whose only delight was to drown and devour unlucky travellers. But we know already that the water-sprites were more than likely so to behave.
In Provence there is a tale told of seven little boys who went out at night against their grandmother's wishes. A little dark pony came prancing up to them, and the youngest clambered on his sleek back, and after him, the whole seven, one after the other, which was quite a wonderful weight for the wee creature; but his back meanwhile kept growing longer and larger to accommodate them. As they galloped along, the children called such of their playmates as were out of doors, to join them, the obliging nag stretching and stretching until thirty pairs of young legs dangled at his sides! when he made straight for the sea, and plunged in, and drowned them all.
