the north coast of Africa in various parts of the Atlas Mountains 

 in Algeria, Tunis, and Morocco ; in large part they are of Bessemer 

 grade. The production of these fields amounted in 1913 to close 

 on 2 million tons, of which three-quarters of a million went to 

 England. The principal producers are Benisaf, Zaccar, and Timezrit 

 in Algeria, Djerissa in Tunis, and Riff in Morocco. It is estimated 

 that the output can be increased by half a million tons or more a 

 year by completing the railway from the port of Bona to the Ouenza 

 and Bou Kadra mines, which are in Algeria near the Tunisian 

 border, and about 120 kilometres from the coast. The reserves for 

 North Africa have been estimated at from 100 to 150 million tons. 



Scandinavia. 



Swedish iron has long been celebrated for its purity and general 

 excellence. The low-phosphorus ore used in its manufacture is in 

 the main magnetite, and comes from a number of old mines in 

 southern Sweden, among which may be mentioned the celebrated 

 Dannemora and Persberg mines. It is smelted locally with charcoal 

 and the reserves are comparatively small. In central Sweden there 

 are some large haematite deposits, as, for example, those of 

 Grangesberg and Norberg, which yield ore averaging 60 per cent 

 iron and high in phosphorus. The reserves are estimated at about 

 100 million tons. 



The main resources of Sweden are in Lappland. Great deposits 

 of iron-ore occur there, mainly magnetite and, as a rule, 

 high in phosphorus, although a trifling proportion is of acid 

 Bessemer grade. The largest and most celebrated ore bodies are 

 those of Kiirunavaara and Gellivare, the former (together with 

 Luossavaara) being credited with a reserve of 738 million tons, 

 and the latter (including KokullskuUe) with 265 million. Both ore- 

 bodies were formerly worked on the open-cast system, but under- 

 ground mining has recently been substituted at Gellivare. They 

 are owned by the Trafikaktiebolag Grangesberg - Oxelosund of 

 Stockholm, and the ores are sold by this Company on a basis of 60 per 

 cent iron, as received, the following grades being distinguished by 

 the phosphorus content : — 



The output is limited by law to 1,300,000 tons per annum for 

 Gellivare, and 5 million per annum for Kiruna. 



The shipping ports are Narvik, on the Atlantic coast, and Lulea, on 

 the Baltic. The former is open all the year round. Before the War
