Communication technology in action - cables which span the Atlantic and a "siphon recorder".
Story about high speed communication cables which span the Atlantic.
A "siphon recorder" is featured. C/U of the machinery which includes a wire leaving a trace on paper which spools through. The zig zag line is transcribed by expert operators on typewriters. Shot of man typing with other men looking over his shoulder. C/U of his hands as he types. C/U of the tape. As the man types, the tape is pulled through a machine and ends up in a big pile on the floor. Weird.
Interesting example of men doing clerical style work - man typing.
