The American Electro Magnetic Telegraph With the Reports of Congress, and a Description of All Telegraphs Known, Employing Electricity or Galvanism

This volume offers a thorough tour of the first American electromagnetic telegraph, laying out every essential piece of the system—from the galvanic battery and the wire to the electro‑magnet and the operating lever. Clear, step‑by‑step illustrations show how the circuits were built and how messages were coded on a simple alphabet of dots and dashes. The author’s concise explanations make the physics behind the instant transmission of letters accessible to a modern ear.

Interwoven with the technical sections are the original reports and correspondence that shaped the project—letters from Samuel F. B. Morse, Treasury memoranda, and congressional hearings that reveal the political drive to knit the nation together with wires. Detailed accounts of experiments, such as a 100‑pair Grove battery spanning 160 miles, illustrate the daring ambition of 1840s engineers. Listening to this narrative gives a vivid sense of the optimism and ingenuity that sparked the age of instant communication.
