An Eskimo just in from a journey of nearly 400 miles appeared at Etah, a bleak native settlement far up on the west coast of Greenland, on May 7 of last year, bearing a letter. The message was written by Dr. Frederick A. Cook of Brooklyn. It was dated March 17, 1908. It came from the Arctic Ocean and contained the news that Dr. Cook was on his way to the North Pole.
