Holroyd was proud of his big dynamo, and expatiated upon its size and power to Azuma-zi until heaven knows what odd currents of thought that and the incessant whirling and shindy set up within the curly black cranium. He would explain in the most graphic manner the dozen or so ways in which a man might be killed by it, and once he gave Azuma-zi a shock as a sample of its quality.
The product of the heat is mechanical motion in the engine. The product of the mechanical motion is electricity in the dynamo. The product of the electric current in the lamp is light-waves in the ether.
Hammer tells a characteristic anecdote of Edison: "A careless boy passing through the station whistling a tune and swinging carelessly a hammer in his hand, rapped a carboy of sulphuric acid which happened to be on the floor above a 'Jumbo' dynamo. The blow broke the glass carboy, and the acid ran down upon the field magnets of the dynamo, destroying the windings of one of the twelve magnets.
But now the slender form and slender shadow of the scientific manager replaced the sturdy outline of Holroyd travelling up and down the lane of light upon the vibrating floor under the straps between the engines and the dynamos. "Have I not served my Lord?" said Azuma-zi inaudibly, from his shadow, and the note of the great dynamo rang out full and clear.
The propellers turned so fast that I could not see the blades turned with that strong, steady, fierce droning buzz that can be heard a long distance and which is a thrilling sound to hear. Norton reached over and attached the little dynamo, at the same time setting the gyroscope at its proper angle and starting it.
The dynamo was buzzing finely. A few splashes of rain fell on him, and he clothed himself in oilskins and rubber boots to watch out the gale, choosing to remain aft where his footsteps over her might reassure the seasick girl below instead of the bridge, where he would have placed himself under normal conditions.
His proposition was derided in the technical press of the period, both at home and abroad. As public opinion can be best illustrated by actual quotation, we shall present a characteristic instance. In the Scientific American of October 18, 1879, there appeared an illustrated article by Mr. Upton on Edison's dynamo machine, in which Edison's views and claims were set forth.
"By the Lord!" cried the lawyer, moved in spite of his preoccupations by the story of danger the other had been relating, "I should think it would turn your hair white every time a dynamo's installed. How did you feel when the fly-wheel broke?" "The fly-wheel isn't on the dynamo, of course," corrected Paul, "so I don't feel responsible for it in a business way, and that's everything.
It was winking and twinkling, and Jack knew that his father was trying to call them. He sent out some flashes by starting the dynamo going and pressing a key devised for the purpose. This, he knew, would cause a similar light attached to his father's apparatus to flash a reply. This done he waited a second and then adjusted the receivers to his ears. "What's the matter?" came his father's voice.
"That is good and strong." "Yes. The wires have no ground-connection outside of the cave. They go out from the positive brush of the dynamo; there is a ground-connection through the negative brush; the other ends of the wire return to the cave, and each is grounded independently." "No, no, that won't do!" "Why?" "It's too expensive uses up force for nothing.
