To be near the sea—their chief source of food—the early settlers made their homes close to the shore, where also they generally found the soil better than further inland. Accordingly most of the houses and crofts are situated along the coast, and in particular at the heads of voes, where often townships and villages have been formed. One striking feature is the bold contrast between the green cultivated township and the dark background of moor or hill, sharply marked off from each other by the ancient “toon” dykes. Still more noticeable are the large tracts of permanent pasture, where one may still see the ruins of cottages, once the homes of crofters who were evicted to make room for sheep. The principal fuel in the islands is peat, the cutting of which, carried on for centuries, ever since the time of Torf Einar, who is said to have taught the natives the use of “turf” for burning, has denuded the surface, and left it blacker than it otherwise would be. That, and the practice of “scalping” turf for roofing purposes, have laid bare great stretches of what might have been fairly good pasture ground. The proportion of arable land is very small compared with the whole land surface of the islands. For this reason Shetland has never figured as an agricultural county; and other causes may be mentioned, such as divided attention between the two branches of industry—fishing and crofting; indifferent soil; variable climate; antiquated methods of cultivation; and want of markets for agricultural produce. Being far removed from the centres of commerce, and having few natural resources in themselves, the islands are almost entirely lacking in manufactures. Fishing and farming are the chief industrial pursuits, while the rearing of native sheep, ponies and cattle form a considerable part of the rural economy. Along with every croft or holding goes the right of common pasturage in the hills and moors, called “scattald.” Crofts would be of little value without this common grazing, which is a remnant of the old Norse odal system of land tenure, and is peculiar to the islands of Shetland and Orkney. The word _scattald_ is from _scat_, a payment, akin to _scot_ in “scot and lot.” 3. Size. Position. Boundaries
