USLHT Dahlia
The United States Lighthouse Tender "Dahlia" was a lighthouse tender serving on the Great Lakes. The first Great Lakes tender to be specifically built for that purpose, she was built in 1874 by Neafie & Levy and placed into commission at Detroit, Michigan. The ship was refitted in 1881, and again in 1891. On 5 November 1907 while docked at Milwaukee she was struck by receiving $450 in damage. On 5 May 1909 she was sold to E. W. Seymour, of Chicago, and rebuilt as passenger and freight carrier, and rechristened "Flora M. Hill" on 12 May 1910 , under which name she served as a ferry between Chicago and Green Bay. The ship became stuck in heavy ice on 11 March 1912, while attempting to enter Chicago Harbor; after her passengers were unloaded, she was allowed to sink to the bottom, where her remains were seen as a shipping hazard and dynamited.
