Samuel F.B. Morse; his letters and journals
A two-volume edition of Samuel F. B. Morse's letters and journals, assembled by his son Edward Lind Morse and published by Houghton Mifflin in Boston and New York in 1914 for general and historical readers. Halftone photographs record early telegraph apparatus in close-up—wire-wound coils, gear trains, relay armatures, wooden frames and stretcher-bar assemblies—giving designers isolated machine parts in high-contrast grey against plain paper, usable as silhouettes or cutout diagrams.
