H. W. JOHNS MANUFACTURING COMPANY, New York, showed a very interesting exhibit of some of their electrical specialties, among which were a new arc lamp hanger and the "Toggle clamp" insulator. Their electrotherm heating pad and H. W. J. street car heaters were shown in operation on the hotel circuits. The simplicity of operating and the method of regulating the temperature by a simple switch interested a large number of persons. Samples and descriptive circulars were freely distributed. The exhibit was in charge of Mr. W. F. D. Crane.
