The Kelpy of Morphie

In 'Folklore of Scottish Lochs and Springs' (1893), James Mackinlay tells the following tale of a captured water horse. 'A pool in the North Esk, in Forfarshire, called the Ponage or Pontage Pool, was at one time the home of a water-horse. This creature was captured by means of a magical bridle, and kept in captivity for some time. While a prisoner he was employed to carry stones to Morphie, where a castle was then being built. One day the bridle was incautiously removed, and the creature vanished, but not before he ex-claimed;

"Sair back an' sair banes,
Carryin' the Laird o' Morphie's stares; 
The Laird o' Morphie canna thrive 
As lang's the kelpy is alive."

His attempted verse-making seems to have gratified the kelpy, for when he afterwards showed himself in the pool he was frequently heard repeating the rhyme. The fate of the castle was disastrous. At a later date it was entirely demolished, and its site now alone remains.'
