DESCRIPTION OF THE AMER ELECTR

Explore the technology that powered one of the earliest electric telegraphs, linking Washington and Baltimore, with clear explanations and detailed illustrations.

This nonfiction volume presents the science behind the electro magnetic telegraph, including how a battery, galvanic fluid, and an electro magnet work together to send messages. It explains the setup of the wires, the clock-driven recording mechanism, and the practical steps used to operate the system. The book is illustrated with fourteen wood engravings that bring the concepts to life.

• How the battery and galvanic reactions generate the signaling current


• Construction and function of the electro magnet as the system’s core


• How the clock work and writing mechanism record transmitted messages


• Ways circuits and conductors are arranged for distant communication

Ideal for readers curious about early electrical communication and the hands‑on explanations of 19th‑century telegraphy.
