firth is commonly considered
to begin, to Ailsa Craig, where it ends, the fairway measures 64 m. Its
width varies from 1 m. at Dumbarton to 37 m. from Girvan to the Mull of
Kintyre. The depth varies from a low-tide minimum of 22 ft. in the
navigable channel at Dumbarton to nearly 100 fathoms in the Sound of
Bute and at other points. The Cumbraes, Bute and Arran are the principal
islands in its waters. The sea lochs all lie on the Highland shore, and
comprise Gare Loch, Loch Long, Loch Goil, Holy Loch, Loch Striven, Loch
Riddon and Loch Fyne. The only rivers of any importance feeding the
Firth are the Ayrshire streams, of which the chief are the Garnock,
Irvine, Ayr, Doon and Girvan. The tide ascends above Glasgow, where its
farther rise is barred by a weir. The head-ports are Glasgow, Port
Glasgow, Greenock, Ardrossan, Irvine, Troon, Ayr and Campbeltown. In
addition to harbour lights, beacons on rocks, and light-ships, there are
lighthouses on Ailsa Craig, Sanda, Davaar, Pladda, Holy Isle, and Little
Cumbrae, and at Turnberry Point, Cloch Point and Toward Point. The
health and holiday resorts on the lochs, islands and mainland coast are
numerous.

CLYDEBANK, a police burgh of Dumbartonshire, Scotland, on the right bank
of the Clyde, 6 m. from Glasgow. Pop. (1891) 10,014; (1901) 21,591.
There are stations at Yoker, Clydebank, Kilbowie and Dalmuir, all
comprised within the burgh since 1886, served by both the North British
and the Caledonian railways. In 1875 the district was almost purely
rural, but since that date flourishing industries have been planted in
the different parts. At Clydebank are large shipbuilding yards and
engineering works; at Yoker there is some shipbuilding and a distillery;
at Kilbowie the Singer Manufacturing Company have an immense factory,
covering nearly 50 acres and giving employment to many thousands of
operatives; at Dalmuir are the building and repairing yards of the Clyde
Navigation Trust. The important Rothesay Dock, under this trust, was
opened by the prince and princess of Wales in April 1907. The
municipality owns a fine town hall and buildings. Part of the parish
extends across the Clyde into the shire of Renfrew.
