No single Arctic expedition of his generation added so greatly to the knowledge of the world as did that of Kane's. In ethnology it contributed the first full account of the northernmost inhabitants of the world, the Etah Esquimaux; in natural history it supplied extensive and interesting information as to the flora and fauna of extreme western Greenland, especially valuable from its isolation by the surrounding inland ice; in physical sciences the magnetic, meteorological, tidal, and glacier observations were extremely valuable contributions; in geography it extended to a higher northerly point than ever before a knowledge of polar lands, and it opened up a practical and safe route for Arctic exploration which has been more persistently and successfully extended poleward than any other. Of Kane's conduct under the exceptionally prolonged and adverse circumstances attendant on his second Arctic voyage, it is to be said that he displayed the characteristics of a high and noble character. Considerate of his subordinates, assiduous in performing his multifarious duties as commander, studying ever to alleviate the mental and physical ailments of his crew, and always unsparing of himself whenever exposure to danger, hardships, or privations promised definite results. It is not astonishing that these qualities won and charmed all his associates, equals or subordinates, and that they followed him unhesitatingly into the perils and dangers that Kane's enthusiastic and optimistic nature led him to brave, with the belief that to will was to do. The career of Kane cannot be more beautifully and truthfully summarized than was done in the funeral sermon over his bier: "He has traversed the planet in its most inaccessible places; has gathered here and there a laurel from every walk of physical research in which he strayed; has gone into the thick of perilous adventure, abstracting in the spirit of philosophy, yet seeing in the spirit of poesy; has returned to invest the very story of his escape with the charms of literature and art, and dying at length in the morning of his fame, is now lamented with mingled affection and pride by his country and the world."
