I've said it twice already, maybe the third time will sink in.

Over the next few days, several hundred messages were exchanged, but those arriving in Newfoundland became almost impossible to decipher - just a jumbled mess of dots and dashes. There was a serious problem with the cable and it was getting worse. Well, the 1858 cable was never fully repaired, and the end finally came when British engineer Wildman Whitehouse mistakenly believed that by increasing the signal voltage he could force the messages through to Newfoundland. The cable simply stopped working altogether.
At the time, increasing voltage by using more powerful batteries made sense. Most experts believed electric current flowed through a cable, like a fluid in a pipe. Increasing the voltage was the equivalent of increasing the pressure in the system - forcing the current through to the other end. But the telegraph was actually carrying pulses, or ripples of currents along the cable, not a continuous stream. . . .
By studying the effectiveness of underwater cabling, scientists were beginning to understand that electric current didn't always flow like water, but was also creating invisible electromagnetic waves, or ripples.
