, it is traditional to carry a stone up from the bottom of a hill to place on a cairn at its top. In such a fashion, cairns would grow ever larger. An old Scottish Gaelic blessing is , "I'll put a stone on your stone". In Highland folklore it is recounted that before Highland clans fought in a battle, each man would place a stone in a pile.
