This condition of the elements did not last long, however. In the space of an hour all was again in brilliant, almost dazzling, sunshine, the rocks and trees on the mountain slopes sparkling with raindrops, and the air became fresh and cool.
It will be observed, as we sail along, that this district is more thickly wooded than almost any other part of Sogn, many of the mountains being quite covered with the dark foliage of pines, even to their summits.
The real forest trees of Norway are the Scotch fir ("furu"), the spruce ("gran"), and hardy birch. These trees grow all over the country, sometimes in unmixed, continuous forests covering large areas, but, generally speaking, they are associated with oak, elm, and ash, in smaller numbers.
In the eastern and southern parts of the country these trees cover the mountain slopes from the bottom of the valleys up to a height of some 2,500 feet above sea-level; at this elevation they are succeeded by hardy forests of birch up to another 1,000 feet; higher than this the shrubs of the mountain plateau—the dwarf birch—only survive.
Small forests are found near the coast in places where they are protected by islands or promontories from the sea winds, but we must go farther inland, and to the heads of the larger fjords, before we can come across any large extent of forest-covered country. The western part of Norway, however, is not remarkable for its forests in comparison with the eastern districts.
Hedemarken Amt (county) has the largest forest area, while Stavanger Amt has the smallest. Of the timber intended for sale, considerable quantities are sent abroad, chiefly spruce and Scotch fir. Birch is found throughout the country, as a rule in company with other trees, and may be seen brightening up the dark coniferous forests with its silver bark and delicate foliage. There are two species of birch—the lowland or white birch, with graceful drooping branches, and the hardy mountain birch, which is rather darker in colour and more stunted in form. It is only in the most northern countries that the "lady of the woods" attains its full beauty. The birch is one of the most useful of trees, the wood being used for a great variety of purposes. The inner bark is used for tanning, and the outer, thicker, bark for the roofs of houses, being placed under the thick covering of turf. The leaves are used as fodder for cattle.
Among other species of trees which grow around the lowland farms and meadows are found the aspen, whose wood is used in the manufacture of matches, the alder, the rowan and hazel, along with the useful ash. The wood of the last-named is largely used in the making of the "lang ski" (snow-shoes).
Timber-felling usually begins in the late autumn. It is an arduous and ofttimes dangerous occupation, and requires hardy and strong men. As the larger forests lie often at a considerable distance from the inhabited districts, many weeks are spent by these woodmen in log huts specially constructed for the purpose in the vicinity of their work.
