Abstract
FASTER telegraphic communication is expected in this day of increasing speed of transportation; and speed must be accomplished with accuracy and the highest degree of service continuity. In order to meet these service demands electrically-operated devices in great variety, including belt-type message conveyer and pneumatic tubes in the larger offices, are finding their way into telegraphic service in ever-increasing quantities. Thus it is that the power plant is more than ever the heart of the system and every means must be provided to maintain an absolutely unfailing supply of electric energy.
