The port, which has regular communication with all the Norwegian coast towns - Hull, Newcastle, Hamburg, &c. - carries on an extensive trade in timber, oil, fish, copper, &c. The industries include shipbuilding, sawmilling, wood-pulp and fish-curing works and machine shops.
A great development has also taken place in Ontario and the eastern provinces, through the use of spruce and other trees, long considered comparatively useless, in the manufacture of wood-pulp for paper-making.
At Skutskar at the mouth of the Dal river are wood-pulp and saw mills, dealing with the large quantities of timber floated down the river; and there are large wood-yards in the suburb of Bomhus.
In the town and district are numerous saw-mills, planing, cotton-spinning and flour-mills, factories for wood-pulp and domestic commodities, also a copper mine (at Omdal).
In northern New England and Canada it is largely manufactured into wood-pulp; it is occasionally used in turnery and for wooden-ware.
