The Mackinac Mission never succeeded in financially supporting itself and, in the late 1830s, its functions were undermined by the decline of the upper Great Lakes fur trade. In 1837,
Michigan Territory was admitted to the Union as a state, and the Ferry family moved to what was to become
Grand Haven. The Mackinac mission complex was abandoned. The decline of the fur trade was caused by "civilization" and the increasing immigration of settlers and
homesteaders into Michigan. For many decades in the early and mid-19th century, Mackinac Island was a key junction point for the short-run lake
steamboats of the day. Many immigrants to
Lake Michigan changed boats at Mackinac Island, and needed places to stay during their stopovers. In 1849 Edward Franks bought the unused Mission House, added a third story to the two-story structure, and reopened it as a hotel/
boarding house. He did not change the structure's name. After the Civil War, pleasure travel increased in northern Michigan, and the Mission House readapted itself as a somewhat spartan excursion resort. As the 20th century began, however, the aging building was increasingly ill-adapted to provide a comfortable experience to travelers. The
Great Depression dealt the Mission House a blow from which it could not recover. The hotel, still operated by the Franks family, closed in 1939. ==Moral Re-Armament and living space==
