I got over the counter to a table behind a wire-gauze, and, like a numb fool, went over the Morse alphabet in my mind before touching the transmitting key, though I knew no code-words, and there, big enough to be seen, was the ABC dial, and who was to answer my message I did not ask myself: for habit was still strong upon me, and my mind refused to reason from what I saw to what I did not see; but the moment I touched the key, and peered greedily at the galvanometer-needle at my right, I saw that it did not move, for no current was passing; and with a kind of fright, I was up, leapt, and got away from the place, though there was a great number of telegrams about the receiver which, if I had been in my senses, I would have stopped and read.
One fact, however, should ever be kept in mind: Whatever may be the extent of the superstructure of electrical science, it is all built upon the foundation of electro-magnetic induction laid by Michael Faraday. The little "magnetic spark" he first produced, and the trembling of his galvanometer-needle, were but signals of the birth of the giant of the century.
