Norwegian ore deposits are very considerable, and the iron pyrites and iron ore mines have a productive capacity far in excess of the present output. A great amount of capital has been sunk in these mines and important technical improve- ments have been effected, with the result that Norwegian mines may now be said to be tech- nically up to date. NITROGEN Norsk Hydro — Elektrisk Kveelstoffaktieselskab (Norsk Hydro) has its power and manufacturing plants, stocks, and harbour works in the county of Telemark. The company has so far developed hydro-electric energy corresponding to an annual productive capacity of 100 000 tons of pure nitrogen. By a further reconstruction of the works for ammonia synthesis this capacity can be substan- tially increased without the necessity of further power development. At the Rjukan, Notodden, and 96
