role in famine relief. Some landowners also provided a great deal of assistance, according to one history of the region: "MacLeod of Dunvegan bought in food for his people, some eight thousand of them" ... MacLean of Ardgour provided food, and introduced new crops into the area - peas, cabbages and carrots ... Sir James Matheson on Lewis spent £329,000 on improving his lands, hoping to provide a more secure future for his people". The government of Britain provided some assistance, thanks to Sir Charles Trevelyan, who arranged for food distribution at Portree and Tobermory. The British Association for the Relief of Distress in Ireland and the Highlands and Islands of Scotland also helped as did donations received from North America. The blight struck again over the next two years, requiring an extra tax on landowners to help feed the population. The British government began encouraging mass emigration. For those who remained new economic opportunities emerged through the export of cattle, commercial fishing and tourism. During the summer season in the 1860s and 1870s five thousand inhabitants of Lewis could be found in Wick on the mainland of Scotland, employed on the fishing boats and at the quaysides. Nonetheless emigration and military service became the choice of many and the archipelago's populations continued to dwindle throughout the late 19th and 20th centuries. By 2001 the population of North Uist was only 1,271. The work of the Napier Commission and the Congested Districts Board, and the passing of the Crofting Act of 1886 helped, but social unrest continued. In July 1906 grazing land on Vatersay was raided by landless men from Barra and its isles. Lady Gordon Cathcart took legal action against the "raiders" but the visiting judge took the view that she had neglected her duties as a landowner and that "long indifference to the necessities of the cottars had gone far to drive them to exasperation". Millennia of continuous occupation notwithstanding, many of the remoter islands were abandoned — Mingulay in 1912, Hirta in 1930, and in 1942 among them. This process involved a transition from these places being perceived as relatively self-sufficient agricultural economies to a view becoming held by both island residents and outsiders alike that they lacked the essential services of a modern industrial economy. There were gradual economic improvements, among the most visible of which was the replacement of the traditional thatched blackhouse with accommodation
