Attention Mariners Mariners are particularly request- ed to immediately notify the nearest superintendent of lighthouses, direct, of any defects or misplacement ob- served in an aid to navigation. Mes- sages may be sent by radio or tele- graph, collect, to the superintendent of lighthouses at Buffalo, Detroit, Sault Ste. Marie and Milwaukee. Such co-operation will materially assist in the prompt remedy of de- fects, and in the effective mainte- nance by the lighthouse service of its aid to navigation on the Great Lakes and connecting waters. House Flags and Stacks William A. Faber, Cleveland, has prepared, in their true colors, copies of the house flags and stack insignia of vessels of the Great Lakes, both American and Canadian. Some 40 or more of these, printed in colors, have been used with an accompanying. ar- ticle headed ‘‘Heraldry of the Lakes” in the Detroit News for July 15. A special article by Mr. Faber with illustrations of a large number of house flags and stack markings of Great Lakes vessels is to appear in the Cleve- land Plain Dealer’s Sunday edition, July 29. The illustrations used in both ar- ticles are part of a complete set cov- ering 80 steamship companies of the Great Lakes.
