To the south of the Firth of L^rne there extends another chain of islands,formed, like the neighbouring coast, of Silurian rocks. This chain includes. NOETHEEN SCOTLAND. 353 Jura—or rather Diura ; that is, Stag Island *—and Islay, the one covered withlofty mountains rising to a height of 2,566 feet, the other the most fertile andbest cultivated of the Hebrides, and rich in metals. The narrow sound whichseparates these islands from the peninsula of Kintyre is navigable, but owing toits swift tidal currents it is dangerous to small vessels. Two of these currentsmeet between Jura and the small island of Searba, producing a tide of doubleheight. The passage of this strait is attended with peril when the tide changes,more especially if the wind blows in a direction contrary to its current andtowards the rocks. At such times no vessel would venture to approach thisfearful race, which the Gaels very appropriately call Coirebhreacain, orCorryvrekan ; that is, Caldron of the Sea. The velocity of the current isvariously estimated at 10 or 13 miles, f Of all the currents in the seas of Scotlandthat of Coirebhreacain is most dreaded ; in it
