Iron in the Adirondacks

F OR years American iron and steel industry has received approximately 85 per cent of its ores from the Lake Superior district, of which most has been of sufficiently high iron content to be used directly without processing; but it is generally agreed that the direct-shipping.ore of the Lake Superior district will be exhausted in less than a generation. In 1942 its exhaustion was expected even sooner, perhaps within a decade, since accelerated war demands would require shipment of 100,000,000 tons of ore per year. When such large shipments did not materialize, experts modified their estimates and now expect depletion in the 1960's
