Our readers can seefor themselves at a glance how manifold has been the increase. The convention of 1887 was called together by President J. FrankMorrison, at the Parker House on August 9, and the list of thosein attendance revives memories of men who did valuable work inthe development of the industry, and have passed away. Mr. Mor-rison, in his address, called attention to the development of the al-. Brush Lighting Plant, Ferdinand Street, Boston, 1887.

It is sharply within the memory of veterans who attendedthe Boston convention seventeen years ago that the impressivefeature of that afifair was the large exhibit made of direct-currentmotors, although singularly enough these were designed for arclighting circuits, to be operated in series, rather than for the incan-descent circuits to be operated in parallel, as virtually all motorsare to-day. The same year, 1887, was a landmark also as being thetime when Tesla came to the front and changed the whole aspect ofthings with his polyphase inventions and motors. In connection with the visit to Boston the Electrical World andEngineer of that day presented to its readers an elaborate wood cutengraving which we are emboldened here to repr
