Edison's amusing description of his experience in shipping the dynamo to Paris when built may appropriately be given here: "I built a very large dynamo with the engine directly connected, which I intended for the Paris Exposition of 1881. It was one or two sizes larger than those I had previously built. I had only a very short period in which to get it ready and put it on a steamer to reach the Exposition in time. After the machine was completed we found the voltage was too low. I had to devise a way of raising the voltage without changing the machine, which I did by adding extra magnets. After this was done, we tested the machine, and the crank-shaft of the engine broke and flew clear across the shop. By working night and day a new crank-shaft was put in, and we only had three days left from that time to get it on board the steamer; and had also to run a test. So we made arrangements with the Tammany leader, and through him with the police, to clear the street--one of the New York crosstown streets--and line it with policemen, as we proposed to make a quick passage, and didn't know how much time it would take. About four hours before the steamer had to get it, the machine was shut down after the test, and a schedule was made out in advance of what each man had to do. Sixty men were put on top of the dynamo to get it ready, and each man had written orders as to what he was to perform. We got it all taken apart and put on trucks and started off. They drove the horses with a fire-bell in front of them to the French pier, the policemen lining the streets. Fifty men were ready to help the stevedores get it on the steamer--and we were one hour ahead of time."
