    Working the transatlantic cables
    From: Paul Hirose
    Date: 2003 May 25, 22:20 -0700

    Submarine cables and telegraphic longitude determinations have been
    discussed here, so this online book may be of interest. It's Frank L.
    Pope's "Modern Practice of the Electric Telegraph", 1881. Mostly it's
    about U.S. overland telegraphy, but the appendix has significant
    detail on undersea cable operations.
    
    There are also data on propagation speed observed in conjunction with
    telegraphic longitude determinations.
    
    By the way, the text was not transcribed to machine readable form by
    scanning or OCR. In a heroic effort, the whole book was hand typed.
    (All illustrations were scanned and are available here too.)
