demonstrated the benefits to those forced to make a new start after eviction. The provision of new accommodation for cleared tenants was often part of a planned piece of social engineering; a large example of this was the Sutherland Clearances, in which farming tenants in the interior were moved to crofts in coastal regions. The intent was that the land allotted to them would not be enough to provide all of their needs, and they would need to seek employment in industries like fishing or as seasonal itinerant farm labourers. The loss of status from tenant farmer to crofter was one of the reasons for the resentment of the Clearances. The planned acts of social engineering needed investment. This money often originated from fortunes earned outside Scotland, whether from the great wealth of Sir James Matheson (the second son of a Sutherland tacksman, who returned from the Far East with a spectacular fortune), the more ordinary profits from Empire of other returning Scots, or Lowland or English industrialists attracted by lower land values in the Highlands. Large amounts of capital were used to start industrial and commercial enterprises or build infrastructure like roads, bridges and harbours, but the return on this capital was very low by contemporary standards. This wasted investment is described by Eric Richards as "a loss to the national economy to be set beside any gains to be tallied." Some of this expenditure was used to build new towns, such as Bettyhill, which received tenants cleared from Strathnaver. This displacement has been compared to the movement of Glaswegians to Castlemilk in the 1950s—with a similar distance from the original settlement and a comparable level of overall failure of the project to produce the anticipated social benefits. In the second phase of the clearances, when population reduction was the primary intention, the actions of landlords can be viewed as the crudest type of social engineering with a very limited understanding of the likely consequences. Failure of the kelp industry The kelp trade was badly affected by the end of the Napoleonic Wars in 1815 and had collapsed totally by 1820. Kelp (or seaweed) was harvested from the seashore at low tide, dried and burnt to yield an alkali extract used in the manufacture of soap and glass. It was a very labour-intensive industry. Production had steadily grown from the 1730s to a peak level in 1810, and was
