At Sletsvig occurs an undoubted ancient moraine, exactly like that at Mosshuus, being composed of huge angular blocks mixed with clayey matter. As it lies opposite a side valley, which here comes in from the west, it may have been a product of that valley; though I am inclined to regard it rather as the accumulation left by the glacier of the Logan vale after it had shrunk up to this point. On the inner side, looking up the main valley, there is a bed of sand, evidently laid down by water, and which it seems allowable to regard as the memorial of a time when this moraine served as a barrier, confining the waters of the river in the form of a lake. In this part of the valley there is a system of irrigation extensively practised by means of wooden troughs laid down along the hill-sides. The cheapness of the material makes it of course highly available. On my journey to-day I met few persons of any kind: amongst these were children offering little platefuls of the wild strawberry for sale. A couple of skillings for a plateful was evidently received as a great prize. Owing apparently to a change in the stratification, the valley makes a rectangular bend at _Viig_--a word, by the way, expressive of a _bend_, being identical with Wick, which so often occurs in Britain in names of places signifying a bay. The Viig station, which is a superior one, is said to contain in its walls some of the timbers of the house in which St Olaf was born--a fact strange if true, seeing that this saint, who was a king of Norway, lived in the tenth century.
