SANDA, an island, in the parish of Southend, district of Cantyre, county of Argyll; containing 11 inhabitants. This is a small island, lying near the outer extremity of the peninsula of Cantyre, and measuring about a mile and a half in length and half a mile in breadth. Its name is of Scandinavian origin, and signifies "sand island." Here is a good natural harbour, but between the island and the main land the sea is extremely turbulent and dangerous, and for two or three months in the year the place cannot be approached by a small boat. Sanda was a common station for the Scandinavian fleets during the contests so long carried on for the possession of Cantyre and the neighbouring islands. There yet exist here the ruins of an old chapel dedicated to St. Columba. On the east side of the island are two islets covered with excellent pasture; and about a league to the south is a dangerous sunken rock, a mile in circumference, called Paterson's rock. See Southend.
