And so on and on and on, thousands of bits for each photo.
At the far end of the relay, a computer would with the greatest of ease turn the combinations of 1s and 0s back into shades of light and dark and produce photo-replications. Then something similar to Jan’s suggestion would be used. Our TP would indeed transmit the whole image of the photo to a specially-trained TP at the Luna City Observatory, who would compare the image against the replication and carefully make any necessary corrections. Finally the whole giboo could be assembled into a duplicate of the original three-dimensional photo and handed over to the astronomers, who could at last begin their work. What a cosmic headache! More to the point: what a cosmic expense! Ron looked a little grim as he began his task, but the rest of us, having no hint of the immensity of it, were in high spirits. We trotted to and fro between the scanner and Ron, bringing him his pages of gray printout with their interminable Is and Os, and he sat there, getting paler and thinner and more poetic-looking by the minute, boosting the data into the TP net. Meanwhile Jan and Saul were already at work making a two-dimensional breakdown of the second photo we planned to transmit, the close-up of the white dwarf and its stellar neighbors.
Ron didn’t collapse until the third day. We non-TPs talk a lot about the soaring wonder of roving the galaxy with your mind. What we overlook, I guess, is the terrible strain of it. And the fact that drudgery is drudgery, with or without TP.
Ron gave. He worked maximum hours, two hours on, two hours off, four shifts a day; and during the rest shifts he seemed impatient to get back to transmitting. God knows why. He had become as involved in the project as we were, but there couldn’t have been much thrill for him in sitting in the corner going 0000011100000 for eight hours a day.
The strain showed on him. He sweated a lot, and his tattoo scars mysteriously became more visible, glowing against his sunken cheeks. Why a quiet, reserved lad like that had ever let a Virangonian needle artist go to work on him is beyond me. The tattoos were wildly obscene, too — according to the Virangonian notion of obscenity. That’s what Mirrik said. Someday I’d like to know why Virangonians consider mouths obscene, because that’s what Ron had on his cheeks: two big toothy tattooed mouths.
We could see him caving in hour by hour, and we tried to be good to him, to help him relax. Mirrik told stories, and Steen Steen did a pretty fair juggling act, and Jan took him for a walk and came back looking a little flushed and rumpled. I wasn’t too happy about that, but I told myself it was All For The Cause. By the second day Ron’s data-transmission speed was about two thirds what it had been at the start, and the next day it was even slower. And he was nowhere near the midpoint of the job. On his fourth shift of the third day he stopped suddenly, looked around the laboratory, blinked, and said, “What time is it? Does anyone know the time? My watch won’t tell me. I’ve asked it, but it won’t tell.”
Then he stood up and, as though all his bones had suddenly been pulled from his body, crumpled and dropped.
The base medic said it was simply exhaustion, ordered Ron not to do any TP work for a week, and hauled him away for a few days of deepsleep recuperation. There were two other TPs available on Higby V: Marge Hotchkiss and a gloomy Israeli named Nach-man Ben-Dov. Since the communications net had to stay open for messages around the clock, this presented certain problems of scheduling. With Ron temporarily out of the hookup, Hotchkiss and Ben-Dov were required to put in twelve Earthnorm hours each day simply handling routine switching and transmitting assignments. That was four hours a day more than the supposed maximum for TP work, and left neither of them any time at all for us. Since they had already been working overtime for the three days that Ron had been transmitting full-time from our lab, neither of them took kindly to an extension of their duties. Particularly dear Marge.
Dr. Schein pulled some strings and we managed to work out a deal. First, it was agreed that the TP staff on Higby III, where some patchy farming settlements have been founded lately, would intercept all incoming messages bound for Higby V. These would be relayed from III to V by ordinary radio transmission; we undertook to pay the extra cost of this. That took about half the burden off the local TP staff. The military people were willing — grudgingly — to defer most outgoing messages until Ron got better, which also helped. The two TPs would still have to be on call four hours a day apiece for normal duties. But that left each one of them four hours a day for us.
We didn’t want any more collapses, though. We decided on a pattern whereby Ben-Dov would come out to the lab and transmit for us for two two-hour shifts, while Marge was sleeping. Then somebody would drive him back into town and get Marge, who’d come out and do two two-hour shifts while Ben-Dov was handling the ordinary stuff at the communications office. Then Ben-Dov would get some sleep and Marge would go back to put in her four hours of office work. That gave us the four daily shifts we had been getting out of Ron, and still left the two TPs time to handle their real work without burning out. Our transmission times were different now, though. Ron had preferred to do his transmitting in one sixteen-hour burst, two hours on and two hours off for the full four shifts, followed by eight hours of exhausted sleep. But Marge and Ben-Dov didn’t work that way. They kept shifting their sleep periods around, now knocking out in the evening, now in the middle of the day; they might put in eight hours of TP (four work, four rest) after breakfast and then eight more (four work, four rest) after dinner, with a nap in between. With sleepdrugs it’s no trick to arrange your slumber pattern to suit your whims, of course, and you know all about the odd living habits of the TP tribe. It made life weird for us, though, since somebody had to be around to assist the TP, bring snacks, correlate the computer printouts, and so forth. We tried to maintain a normal digging schedule at the site — yes, we’re still digging through all this — and yet have somebody available to hold the TP’s hand no matter what hour.
Pilazinool, who needs one hour of sleep out of every twenty-four, did much more than his share of this work. Too bad, for his gifts were needed elsewhere.
We did manage to get most of the data transmitted. Marge was no joy to have around the lab, and even less fun to drive back and forth from town — I made a point of avoiding that assignment — but I’ll give her credit: she’s got superb TP stamina. She’d come in, pick up the data sheets, start sending, and hum along on the dreary job faster than Ron ever did, and with less apparent effort. I suspect she could have volunteered for overtime work and not suffered for it. But of course the idea never entered her head.
Ben-Dov was an odd one: about fifty years old, graying, paunchy, always needing a shave, not at all displaying the conqueror-of-the-desert image that most Israelis try to project. Yet behind his sloppiness he was made of iron. We talked a little; he said that until the age of thirty he had never even been outside of Israel, though he moved around a lot inside the country; he grew up in Cairo, studied in Tel-Aviv and Damascus, and drifted around to Amman, Jerusalem, Haifa, Alexandria, Baghdad, and the other important Israeli cities. Then he got the urge to travel and signed up for TP duty at the Ben-Gurion Kibbutz on Mars. Like a lot of other TPs he’s kept on wandering, getting farther and farther from Earth with each change of post, but always volunteering for bleak, desolate planets like Higby V.
