METALS

SUMMARY. It thus appears that, as regards iron, copper, lead, 

 and antimony, the present actual output from mines within 

 the empire is not sufficient to supply the needs of the empire, 

 but that there are undeveloped resources in these metals, 

 which are more than sufficient to make us self-supporting. 



With regard to asbestos, graphite, cobalt, manganese, 

 nickel, tungsten, zinc, and tin, the empire's production is 

 sufficient for its needs, while in the case of tin and gold we 

 not only produce sufficient for ourselves, but actually supply 

 60 per cent, of the whole world's needs.
