Across Colgrave Sound lies Fetlar, one of the most fertile of the islands. It is elevated towards the north-east, where Vord Hill rises 521 feet. Hereabout the coast is precipitous and very imposing. The principal openings are Tresta Wick in the South and Gruting Wick in the east. Brough Lodge is a calling-place for steamers. [Illustration: Muckle Flugga Lighthouse (Most northerly part of the British Isles)] Unst is the most northerly part of the British Isles. In the south is the harbour of Uyea, east of which is Muness with Muness Castle. The principal harbour in Unst is Balta Sound, completely protected by the islands of Balta and Huney. Further north is Haroldswick, named after Harold Fairhair of Norway, who landed here on his expedition against his rebellious subjects. After passing the sandy bay of Norwick and rounding Holm of Skaw, we reach the northern extremity of Unst. The heights of Saxa Vord and Hermaness hem in the entrance to Burrafirth. Rising from a group of rocks, about a mile to seaward, is the Flugga, with a fine lighthouse, which shows a fixed light, with white and red sectors. From Hermaness to Blue Mull Sound, the west of Unst is bold and rocky, with only one inlet of importance, Lunda Wick. 8. Round the Coast—(_b_) Along the West from Fethaland to Fitful Head A mile or two off the point of Fethaland are the Ramna Stacks, huge rocks like giant sentinels guarding the northern extremity of the Mainland. From this point to the isle of Uyea, and onwards to Ronas Voe, the chief feature of the coast is the high and rugged granite cliffs, which gradually increase in height till the voe is reached. This fine natural harbour, lying round the base of Ronas Hill, forms, with Urafirth on the opposite side, an extensive peninsula to the westward. The coast line of the peninsula is rugged and much indented, with wonderful caves and subterranean passages, wrought out by the action of the sea, the Grind of the Navir and the Holes of Scradda being the most remarkable. Off the south coast lie the famous Dore Holm with its natural arch, and the Drongs, resembling a ship under sail. Hillswick, in Urafirth, is the terminal port of call for steamers on the west side, and forms a convenient centre for the many fine trout-fishing lochs in the neighbourhood.
