The emigration from 1848 to 1852,saw the majority sail to Montreal on board the Barlow, Charlotte, Birman, Onyx and Conrad. In 1849, 600 people left Tiree for Canada. Many of the emigrants were offered grants but the Campbell Duke wielded his big stick and admitted himself to 40 of these evictions. There are still twelve traditional thatched buildings on Tiree, the highest concentration in Scotland. Their design and style of thatching is unique, partly dressed stones laid without mortar in a double wall. Between the two skins is a layer of sand. Walls are six feet thick, deep inset windows and one door. The roof trusses are set onto the inside wall and water runs off the roof, down between the two layers of stone. The material for thatching is muran (grass) which grows on the beach dunes. The muran is laid loose, new thatch applied over the old every two years. Traditionally it was held down with an elaborate design of rope with stone weights, chicken wire or fishing nets are now used. If you seek peace, space and pure air, Tiree has it all, sky and sea stretch from horizon to horizon, no woodland and only three sizeable hills on a flat landscape, the only sound isthe waves lapping on the white sand beaches. The island – believe it or not – is one of the sunniest places in Britain, with a warm Gulf Stream, winter temperatures are generally higher than on the mainland. To the eas, the mountains of Mull stand out, Rhum and Skye, in the south Jura, in the north Uist, lie waiting your inspection.
