Turned around, ignoring me as I buttoned my vest. From his pocket removed an object and held it up for my inspection. Surprised to see a common fountain pen.
“If I touch this pen to your hand — hand, please! — what do you feel?”
Extended hand, palm up. He pressed end of pen lightly into skin of my palm.
“I feel a pressure — the pressure of the pen. The pressure of an object.”
“Very good. And you would say, would you not, that the skin is adapted to feel things in that way — to identify objects by the sense of touch. But this pen of ours is a rather large, coarse object. Consider a finer object — this, for example.”
From another pocket: a single dark bristle. Might have come from a paintbrush.
“Your hand, please. Concentrate your attention. I press here — yes? — and here — yes? — and here — no? No? Precisely. And this is a somewhat coarse bristle. If we took a very fine bristle, you would discover even more clearly that only certain spots on the skin give the sensation of touch. We have mapped out these centers of touch and are now able to replicate several combinations with some success.”
He reached over to cylinders and picked one up, looking at it as he continued. “It is a long and difficult process. We are at the very beginning.” Turning cylinder slowly in his hand. “The key lies here, in this hollow beechwood tube — the haptogram. You see? The surface is covered with hard wax. Look. You can see the ridges and grooves. They control the flow of current. As the haptogram rotates, the wax pushes against this row of nickel rods: up here. Yes? This is clear? Each rod in turn operates a small rheostat — here — which controls the current. You understand? The current drives the corresponding coil in the glove, thereby moving the pin against the skin. Come here.”
He set down cylinder and stepped over to torso. Unfastened back. Carefully pulled away a strip of lining.
“These little devices beneath the brass caps — you see them? Each one is a miniature electromagnet. Look closely. You see the wire coil? There. Inside the coil is a tiny iron cylinder — the core — which is insulated with a sleeve of celluloid. The core moves as the current passes through the coil. To the end of each core is attached a thin rod, which in turn is attached to the lining by a fastener that you can see — here, and here, and all along the lining. Ah, those rods!”
He shook his head. “A headache. They have to be very light, but also stiff. We have tried boar’s bristle — a mistake! — zinc, too soft; steel, too heavy. We have tried whalebone and ivory. These are bamboo.”
Sighing. “It is all very ingenious — and very unsatisfactory. The haptograms can activate sequences of no more than six seconds. The pattern then repeats. And it is all so very … clumsy. What we need is a different approach to the wax cylinder, a more elegant solution to the problem of the overall design.”
Pause — glance at sheet-draped object. Seemed to fall into thought. “There is much work to do.” Slowly reached into pocket, removed ring of keys. Stared at keys thoughtfully. “We know nothing. Absolutely nothing.” Slowly running his thumb along a key. Imagined he was going to press tip of key into my palm — my skin tingling with an expected touch — but as he stepped toward door I understood that our session was over.
NOVEMBER 7. Last night the Wizard shut himself up in Room 12: seven o’clock to three in the morning. Rumor has it he is still refining the automatic adjustment for phonograph cylinder. Hell-bent on defeating the graphophone. Rival machine produces a less clear sound but has great practical advantage of not requiring the wax cylinder to be shaved down and adjusted after each playing. The Wizard throws himself onto cot for two hours, no more. In the day, strides from room to room on second floor, quick, jovial, shrewd-eyed, a little snappish, a sudden edge of mockery. A university man and you don’t know how to mix cement? What do they teach you? The quick sketch: fixed gaze, slight tilt of head. Try this. How about that? Acid stains on his fingers. The Phonograph Works, the electrical lab, the Photographic Building. Alone in a back room in chemical lab, quick visit to Box, up to Room 5, over to 12. The improved phonograph, moving photograph, haptograph. Miniature phonograph for speaking doll. Ink for the blind, artificial ivory. A machine for extracting butter directly from milk. In metallurgical lab, Building 5, examines the rock crushers, proposes refinements in electromagnetic separators. A joke in the courtyard: the Wizard is devising a machine to do his sleeping for him.
I think of nothing but the haptograph.
NOVEMBER 12. Not a word. Nothing.
NOVEMBER 14. Haptograph will do for skin what phonograph does for ear, kinetoscope for eye. Understood. But is comparison accurate? Like phonograph, haptograph can imitate sensations in real world: a machine of mimicry. Unlike phonograph, haptograph can create new sensations, never experienced before. The upward-flowing ripple. Any combinations of touch-spots possible. Why does this thought flood my mind with excitement?
NOVEMBER 17. Still nothing. Have they forgotten me?
NOVEMBER 20. Today at a little past two, Earnshaw entered library. Saw him hesitate for a moment and look about quickly — the Wizard long gone, only Grady from chemical lab in room, up on second gallery — before heading over to my desk. Handed me a book he had borrowed some weeks before: a study of the dry gelatin process in making photographic plates. Earnshaw’s appetite for the technical minutiae of photography insatiable. And yet: has never owned a camera and unlike most of the men appears to have no desire to take photographs. Have often teased him about this passion of his, evidently entirely mental. He once said in reply that he carries two cameras with him at all times: his eyes.
Touché.
“A lot of excitement out there,” I said. Sweeping my hand vaguely in direction of Photographic Building. “I hear they’re getting smooth motions at sixteen frames a second.”
He laughed — a little uncomfortably, I thought. “Sixteen? Impossible. They’ve never done it under forty. Besides, I heard just the opposite. Jerky motions. Same old trouble: sprocket a little off. This is for you.”
He reached inside jacket and swept his arm toward me. Abrupt, a little awkward. In his hand: a sealed white envelope.
I took envelope while studying his face. “From you?”
“From”—here he lowered his voice—“Kistenmacher.” Shrugged. “He asked me to deliver it.”
“Do you know what it is?”
“I don’t read other people’s mail!”
“Of course not. But you might know anyway.”
“How should — I know you’ve been down there.”
“You saw me?”
“He told me.”
“Told you?”
“That you’d been there too.”
“Too!”
Looked at me. “You think you’re the only one?”
“I think our friend likes secrets.” I reached for brass letter-opener. Slipped it under flap.
“I’ll be going,” Earnshaw said, nodding sharply and turning away. Halfway to door when I slit open envelope with a sound of tearing cloth.
“Oh there you are, Earnshaw.” A voice at the door.
Message read: “Eight o’clock tomorrow night. Kmacher.”
