The seamen died of scurvy, and it was two hundred years before they found out how to stay alive on salted food, by drinking lime juice. Safe from scurvy, they reached the gate of the passage at Lancaster Sound, but there the winter caught them, so that their ships were squashed in driving ice, and the men died of cold and hunger. Then the explorers got ships too strong to be crushed; they copied the dress of the Eskimo to keep them warm; and they carried food enough to last for years. Deeper and deeper they forced their way into the Arctic, but now they neared the magnetic pole where the compass is useless, in belts of drifting fog darker than midnight. Still they dared to go on, but the inner channels of the Arctic were found to be frozen until the autumn gales broke up the ice-fields, leaving barely six weeks for navigation before the winter frosts. At that rate the three-thousand-mile passage would take three years. Besides, the ship must carry a deck load of sledge dogs with their food, so that the men might escape overland in case they were cast away. Only a big ship could carry the supplies, but once again the seamen dared to try. And now came the last test to break men’s hearts--the sea lane proved to be so foul with shoals and rocks that no large vessel could possibly squeeze through. At last, after three hundred years, the British seamen had to own defeat. Our explorers had mapped the entire route, but no ship could make the passage because it was impossible to raise money for the venture. Why should we want to get through this useless channel? Because it was the test for perfect manhood free from all care for money, utterly unselfish, of the highest intellect, patience, endurance and the last possible extremity of valor. And where the English failed a Norseman, Nordenskjöld made the Northeast passage round the coast of Asia. Still nobody dared to broach the Northwest passage round America, until a young Norse seaman solved the riddle. Where no ship could cross the shoals it might be possible with a fishing boat drawing only six feet of water. But she could not carry five years’ supplies for men and dogs. Science came to the rescue with foods that would pack into a tenth part of their proper bulk, and as to the dog food, one might risk a deck load big as a haystack, to be thrown off if the weather got too heavy. Still, how could a fishing boat carry twenty men for the different expert jobs? Seven men might be discovered each an expert in three or four different trades; the captain serving as the astronomer and doctor, the cook as a naturalist and seaman. So Roald Amundsen got Doctor Nansen’s help, and that great explorer was backed by the king. Help came from all parts of Scandinavia, and a little from Great Britain.
