Some ancient stone crosses are yet standing near this ancient pile [i.e. the ruins of Iona Abbey], with inscriptions no longer intelligible. Previous to the Reformation, there existed 860 of various sizes and beautiful workmanship. Many of which, were carried away to adorn the streets of distant towns and villages; and in Cowal, there is a popular tradition, that a great number of crosses and tomb-stones were sunk in Loch Fyne opposite to Strachur, where, if we believe the fishermen of that place, they are still to be seen at low water.
