BUSINESS. · · The H. W. Johns Manufacturing company will offer an excellent opportunity at the St. Louis convention for the inspection of the H. W. J. system of heating street cars by a fully equipped car, forming part of the exhibit of the American Car company. Sixteen heaters with a regulating switch will constitute the equipment. Other heaters will be exhibited in the company's space not far from the door to the Convention Hall. These will also be in operation. A complete display will be made of the moulded Mica trolley line insulating materials which have proven conspicuous features of previous exhibitions. Especial attention will be called to the Hercules mechanical clip, which was originally a Chicago idea and which has been revived by the Jobns-Pratt company. Vulcabeston for controller and other uses will be shown. The interests of the company will be looked after by H. A. Reeves of the Chicago house, J. H. MacLennan of St. Louis, J. Emory Meek of the New York branch, J. W. Perry of Philadelphia and E. B. Hatch of the Johns-Pratt company of Hartford, Conn. · ·
