A calculation has been made by which it appears that, of overland and submarine telegraphs, there are completed and in progress of construction at the present time, the following lengths: United States 33,000 miles overland; South America, 1,500 miles, overland ; Europe, 37,900 miles, overland; India, 5,000 miles, overland. Submarine, Europe and America, 900 miles. Total, 78,350 miles. This aggregate will be increased 1,700 miles by the completion of the Atlantic Telegraph. Of the European and Indian telegraphs, not more than from six to seven thousand miles of the lines commenced are finished, yet the next si" months will probably see them all in operation.
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
