One could get lost. In my 10 minutes of avoiding work that I spent researching this, it’s certainly obvious that the development of rail lines and telegraph lines were intimately linked. And the interconnection of systems and building of trans-border lines seems like a rich research topic. And both phenomenon grew so quickly, with the first commercial electric telegraph 1846, and widespread networks by 1860. Looks like they started figuring out undersea cables about 10 minutes after commercial telegraphs became a thing!</span></div><p class="MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span style="color: rgb(31, 73, 125);" class=""> </span></p><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">Did you see this in WorldCat?</span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">Map of the submarine telegraph between America & Europe, with its various communications on the two continents.</span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">Groom, Thomas & Co. 1856 (there’s several variations)</span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class=""> Note the ‘with its various communication on the two continents” subtitle.</span></div><p class="MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span style="color: rgb(31, 73, 125);" class=""> </span></p><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">And this:</span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; text-indent: 0.5in;" class=""><span style="color: rgb(31, 73, 125);" class=""><a href="https://www.loc.gov/resource/g3201p.ct000465/" style="color: rgb(149, 79, 114); text-decoration: underline;" class="">https://www.loc.gov/resource/g3201p.ct000465/</a></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">but it would be difficult to trust the map of Europe I suppose – it seems pretty sketchy from a data point of view.</span></div><p class="MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span style="color: rgb(31, 73, 125);" class=""> </span></p><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">And what constitutes cross-border in 1850s – 60s Europe? <span class="Apple-converted-space"> </span></span></div><p class="MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span style="color: rgb(31, 73, 125);" class=""> </span></p><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">Finally: here is a page out of an 1891 Stielers hand-Atlas:</span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class=""> <span class="Apple-converted-space"> </span><a href="https://commons.wikimedia.org/wiki/File:1891_Telegraph_Lines.jpg" style="color: rgb(149, 79, 114); text-decoration: underline;" class="">https://commons.wikimedia.org/wiki/File:1891_Telegraph_Lines.jpg</a></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">1891 being a little too late perhaps?
