"I worked feverishly. I think I must have worked myself into a sort of frenzy, a sort of madness. I never mingled with people, and I became bitter and despondent. One day my nerves broke down. I smashed everything in my laboratory, all my models, all my apparatus, and I burned the plans and papers I had labored over for years.
"My physician told me that I must rest and recuperate. He told me I must interest myself again in daily life, in people and inanimate things. So I went away. For the next few years I traveled. I tore myself away from everything scientific and plunged into the business of living. Almost overnight I became an adventurer, tasting sensations with the same ardor I had once given to my work. I went back to art, to painting and literature and music. I was a connoisseur of wines and of foods and of women. I was an experimenter with life.
"Little by little, though, the zest of that passed away. I grew tired of my dilettantism. And eventually I found that, even while I had been moving about the world and experiencing its curious values, my mind had been grappling quietly, subconsciously, with my old problem. The change in my life had given me the wider outlook, the keener understanding necessary to the accomplishment of my task. In the end, I went back to it again with renewed vigor. With greater power, too, and greater sanity."
Melbourne paused here. Sensing his need, I brought him a highball, and one for myself. He tasted it with a quizzical expression.
"They call this whisky nowadays!" he observed absently, with quiet irony. I wanted to hear the rest of his account.
"Go on with your story, sir," I begged him.
"The rest is simple enough—but it's the meat of the narrative. You see, I had to revise the way I was going about my work, and I went at it at a new angle. By this time wireless telegraphy was being widely developed, and there were many features of it that appealed to me. With the knowledge I had gained during my first feverish years of experiment, however, I was able to go far beyond what has been done in recent times with radio.
"I used a system differing in many respects from that of the commercial radio. We haven't time now to go into all that—I can tell you later, and it involves much that is highly technical and still secret. It is sufficient if I explain that my object was to evolve and fuse methods for doing with each of the senses what radio does with sound. Telephotography was the simplest problem—the others required an almost superhuman amount of labor.
"But my biggest job was to combine them. And, to do that, I had to use knowledge I had gained not only in the laboratory but in my wanderings about the earth—not only in the colleges and salons of Europe and America, but in the bazaars and temples of India, Egypt, China. I had to unite the lore of ancient and modern civilizations, and I created a new factor in electrical science. I suppose the simplest and most intelligible name for it would be mental telepathy. But it is more than that, and basically it is as simple and material as your own motion pictures."
