Muck
island of the Small Isles, in Scotland, United Kingdom
Muck is one of the Small Isles off the west coast of Scotland. It's the smallest of the four inhabited Isles, about 2½ miles east-west by a mile north-south, and has no shop, church or even a letter-box. It's low-lying and its east is fertile, with a range of accommodation, so in summer its resident population of 40 is doubled; its west is rugged, with rough grazing. Muck is owned by the MacEwen family, who've lived and farmed here for a century. Back in 1785 the owner hated being called "Lord of Muck" and tried to persuade Johnson & Boswell that it was "Monk". The name probably means pigs (Gaelic mouach) but is now thought to refer to porpoises, "sea-pigs", which abound in these waters.
