MULL, the largest island of the Inner Hebrides, Argyllshire, Scotland. Pop. (1921) 3,389. It is bounded on the west and south by the Atlantic, on the north and north-east by the Sound of Mull, and on the east and south-east by the Firth of Lorne. Its greatest length is 27 m., and its greatest breadth 20 m. The coast is deeply indented, and there are several freshwater lakes. The principal mountains are Ben More (3,185 ft.), Ben Buy and Ben Creach. In the basaltic cliffs near Carsaig are numerous arches and caverns. Sheep and cattle are raised, and barley, oats and potatoes grown. Owing to the damp climate the island is better suited for grazing than for cultivation. Granite is quarried. The fishing and shoot ing attract many sportsmen. There are several ancient castles, the principal being those of Duart and Aros. Close to the former is a lighthouse erected in memory of William Black, the novelist (d. 1898). About midway between Mull and Lismore is the Lady rock, visible at low water, on which, in 1523, Lachlan Maclean of Duart exposed his wife, a daughter of the second earl of Argyll, expecting that she would be drowned by the flowing tide. She
was, however, saved by her clansfolk and her husband was after wards slain by her brother. Tobermory ("the Well of Mary," so called from a spring of local celebrity), which rises from a pic turesque bay, is the only town (pop. 85o). Founded in 1788 as a station for fishing-boats, it has a harbour and considerable local trade. It is also a summer resort, with communication by steamer with Oban and Glasgow. Off the north-western shore of Mull, separated by a narrow strait, lie the inhabited islands of Ulva, m. long and 21 m. broad, and Gometra. Little Colonsay lies about 2 m. south of Ulva. Farther west is the small group of the Treshnish Isles.
