From Memphis Edison went to Louisville. Here he remained for about two years. It was while he was there that he perfected the peculiar vertical style of writing which has since been his characteristic style. He says of this form of writing, an example of which is given above: "I developed this style in Louisville while taking press reports. My wire was connected to the 'blind' side of a repeater at Cincinnati, so that if I missed a word or sentence, or if the wire worked badly, I could not break in and get the last words, because the Cincinnati man had no instrument by which he could hear me. I had to take what came. When I got the job the cable across the Ohio River at Covington, connecting with the line to Louisville, had a variable leak in it, which caused the strength of the signaling current to make violent fluctuations. I obviated this by using several relays, each with a different adjustment, working several sounders all connected with one sounding-plate. The clatter was bad, but I could read it with fair ease. When, in addition to this infernal leak, the wires north to Cleveland worked badly it required a large amount of imagination to get the sense of what was being sent. An imagination requires an appreciable time for its exercise, and as the stuff was coming at the rate of thirty-five to forty words a minute, it was very difficult to write down what was coming and imagine what wasn't coming. Hence it was necessary to become a very rapid writer, so I started to find the fastest style. I found that the vertical style, with each letter separate and without any flourishes, was the most rapid, and that, the smaller the letter, the greater the rapidity. As I took on an average from eight to fifteen columns of news report every day, it did not take long to perfect this method." The telegraph offices of those early days were very crude as compared with the equipments of modern times. The apparatus was generally in a very poor condition, and the wiring was of a haphazard kind. The conditions during the time of the Civil War all tended to demoralization, both of operators and apparatus.
