in Sweden is made by means of the basic processes. Most of the ores 
rich in phosphorus are exported to Germany and England. The export 
in 1905 amounted to 3:3 M.T. 
Also most of the ores in the province of the south coast of Norway 
are rich in phosphorus. 3 
C. Lean Ores.—Though low-grade ores are met with in all ore dis- 
tricts, it is chiefly in the ore provinces of Northern Norway and of Syd- 
Varanger that it is predominating. Owing to the low percentage of iron, 
the ore must be subject to magnetic concentration before being smelted. 
This class of ore has not yet been utilised for the home manufacture 
either in Sweden or in Norway. Preparations are going on for exporting 
it on a large scale, not only from Dunderland, but also from the ore-fields 
of Ofoten, Salangen, and Syd-Varanger. The ores of Dunderland contain 
about 38 per cent. of iron, mostly as hematite ; the percentage of phos- 
phorus is on an average 0-2. Through magnetic concentration it will be 
possible to reduce the phosphorus very considerably, and to export a 
briquetted ore containing about 65 per cent. of iron and only 0-016 per 
cent. to 0:026 per cent. of phosphorus. 
For meeting the demand of iron ore in the western part of Europe 
this source of ore will in the next year without doubt become of very 
great importance.

I will conclude with a few words about the ore politics of Sweden, 
which has caused some alarm in the countries in demand of iron ores. 
In respect to abundant iron ore supplies, the Scandinavian Peninsula has 
been richly provided by Nature, but at the same time the lack of fuel 
makes it difficult to utilise the ores for the home industry. Owing to 
that, an export of iron ore has arisen during the last twenty years, but it 
was always the aim of the Government and of the leading parties of the 
Riksdag to confine this export within certain limits. Thus, when in the 
year 1898 the railway from Gellivare to the port of Narvik was to be 
built for the purpose of opening up the ore province of Norrbotten, and 
prtting the largest ore deposit of Sweden in communication with a port 
o1 the Atlantic coast, the necessary means were voted by the Riksdag 
only on the condition that the ore exported on this railway, vid the port
