THE ELECTRICAL EXHIBITION held at Madison Square Garden, New York, during the month of May, showed such progress over the one held at the Grand Central Palace two years previously, particularly in features of general interest and in its instructional departments, there being more than a score of the latter. That the public appreciated the efforts made to entertain them was shown by an attendance under remarkably adverse weather conditions that probably no other show could have obtained.



The puncture proof qualities of porcelain goods manufactured by the firm of R. Thomas & Sons' Company, East Liverpool, Ohio, was most comprehensively displayed by a series of tests with a potential of 60,000 volts, alternating current. For this purpose a Westinghouse testing transformer was used. The results obtained show that the Boch insulator manufactured by the concern has an enormous potential resisting ability. A great variety of porcelain insulators and other electrical fittings were shown, and the attendance at the booth was always large when tests with the 60,000-volt transformer were in progress.
