An explorer named Fridtjof Nansen was lost with one companion in the Arctic wastes. By miscalculation they ran out of all their supplies. They ate their dogs, the dog's harnesses, the whale oil for their lamps. Nansen's companion gave up and lay down to die. But Nansen did not give up. He told himself, "I can take one step more." As he plodded heavily through the bitter cold, step after step, suddenly across an ice hill he stumbled upon an American expedition that had been sent out to find him.
