Argillite carvings (circa 1841) of sea captains by the Haida Indians of Queen Charlotte Islands, British Columbia, stand before a model of the Vincennes, the flagship for the U.S. Exploring Expedition of 1838-42. The dissemination of new information on whaling and sealing grounds proved a boon to New England's whaling industry, shown above in action in an 1835 sketch by Cornelius B. Hulsart.
