The steambarge Monitor foundered 20 miles northeast of Racine in a heavy northeast gale. When the steamer left Pierpoint, MI, it was noticed that the vessel was leaking slightly at the stern pipe. Out in the lake the leak increased until the three pumps could not keep up. The steamer suddenly listed to port, water poured in thru the gangway and went down in 15 minutes. After a desperate struggle, the entire crew and passengers managed to reach the small sixteen foot long boat, and after surviving terrific seas were eventually picked up by the schooner Melitta. An attempt was made to locate the wreck in the hopes it might still be afloat, but there is no record of success.
