Beneath the Arctic ice last week for a several-weeks stay was the second U.S. submarine in eight days to take the short route to the North Pole: the nuclear-powered Skate. The first, Nautilus, ducked under the Pacific and emerged six days later in the Atlantic, mostly to prove it could be done. The Skate, skippered by young (37) Commander James Calvert, has popped up several times in ice gaps -within missile range of Russia.

The margin for error at the rendezvous point is about 30 minutes, and the slightest miscalculation...

Recent price rises in steel and other raw materials, said the report, were encouraged by the Mideast crisis, and might prove to be transitory. In one case they had already proved so; custom smelters of copper, who fortnight ago raised their prices ½? to 27? a lb., last week cut their prices back to 26½?. But steel showed no sign of retreat, as steel price hikes spread to 65% of the industry...
