All this was, as I have said, theoretical, and it was mighty lucky for Graham Bell that it was, for had his harmonic telegraph been a well behaved apparatus that always did what its parent wanted it to do, the speaking telephone might never have emerged from a certain marvelous conception, that had even then been surging back of Bell’s high forehead for two or three years. What that conception was, I soon learned, for he couldn’t help speaking about it, although his friends tried to hush it up. They didn’t like to have him get the reputation of being visionary, or—something worse. To go on with my story; after Mr. Farmer’s peace-making machines were finished, I made half a dozen pairs of the harmonic instruments for Bell. He was surprised, when he tried them, to find that they didn’t work as well as he expected. The cynical Watson wasn’t at all surprised for he had never seen anything electrical yet that worked at first the way the inventor thought it would. Bell wasn’t discouraged in the least and a long course of experiments followed which gave me a steady job that winter and brought me into close contact with a wonderful personality that did more to mould my life rightly than anything else that ever came into it. I became mightily tired of those “whiners” that winter. I called them by that name, perhaps, as an inadequate expression of my disgust with their persistent perversity, the struggle with which soon began to take all the joy out of my young life, not being endowed with the power of Macbeth’s weird sisters to “Look into the seeds of time, And say which grain will grow and which will not.” Let me say here, that I have always had a feeling of respect for Elisha Gray, who, a few years later, made that harmonic telegraph work, and vibrate well-behaved messages, that would go where they were sent without fooling with every receiver on the line. Most of Bell’s early experimenting on the harmonic telegraph was done in Salem, at the home of Mrs. George Sanders, where he resided for several years, having charge of the instruction of her deaf nephew. The present Y. M. C. A. building is on the site of that house. I would occasionally work with Bell there, but most of his experimenting in which I took part was done in Boston. Bell’s Theory of Transmitting Speech Mr. Bell was very apt to do his experimenting at night, for he was busy during the day at the Boston University, where he was Professor of Vocal Physiology, especially teaching his father’s system of visible speech, by which a deaf mute might learn to talk—quite significant of what Bell was soon to do in making mute metal talk. For this reason I would often remain at the shop during the evening to help him test some improvement he had had me make on the instruments.
