But after an hour or so of pacing up and down the room and of batting out his brains, he finally gave up and let the answer out.
He was quite calm when he rolled up his sleeve and opened up the box. And he was a matter-of-fact physician when he lifted out the pad and slapped it on his arm.
But his hand was shaking when he rolled down the sleeve so Janet wouldn't see the pad and ask a lot of questions about what had happened to his arm.
Tomorrow all over the world outside Millville, people would line up before the clinic doors, with their sleeves rolled up and ready. The lines, most likely, would move at a steady clip, for there was little to it. Each person would pass before a doctor and the doctor would slap a pad onto his or her arm and the next person would step up.
All over the world, thought Doc, in every cranny of it, in every little village; none would be overlooked. Even the poor, he thought, for there would be no charge.
And one could put his finger on a certain date and say:
"This was the day in history when disease came to an end."
For the pads not only would kill the present ailments, but would guard against them in the future.
And every twenty years the great ships out of space would come, carrying other cargoes of the pads and there would be another Vaccination Day. But not so many then — only the younger generation. For once a person had been vaccinated, there was no further need of it. Vaccinated once and you were set for life.
Doc tapped his foot quietly on the floor of the porch to keep the rocker going. It was pleasant here, he thought. And tomorrow it would be pleasant in the entire world. Tomorrow the fear would have been largely filtered out of human life. After tomorrow, short of accident or violence, men could look forward confidently to living out their normal lifetimes. And, more to the point, perhaps, completely healthy lifetimes.
The night was quiet, for the children finally had gone in, giving up their play. And he was tired. Finally, he thought, he could admit that he was tired. There was now, after many years, no treason in saying he was tired.
Inside the house he heard the muffled purring of the phone and the sound of it broke the rhythm of his rocking, brought him forward to the chair's edge.
Janet's feet made soft sounds as they moved toward the phone and he thrilled to the gentleness of her voice as she answered it.
Now, in just a minute, she would call him and he'd get up and go inside.
But she didn't call him. Her voice went on talking.
He settled back into the chair.
He'd forgotten once again.
The phone no longer was an enemy. It no longer haunted.
For Millville had been the first. The fear had already been lifted here. Millville had been the guinea pig, the pilot project.
Martha Anderson had been the first of them and after her Ted Carson, whose lung had been suspicious, and after him the Jurgen's baby when it came down with pneumonia. And a couple of dozen others until all the pads were gone.
And the alien had come back.
And the alien had said — what was it he had said?
"Don't think of us as benefactors nor as supermen. We are neither one. Think of me if you will, as the man across the street."
And it had been. Doc told himself, a reaching by the alien for an understanding, an attempt to translate this thing that they were doing into a common idiom.
And had there been any understanding — any depth of understanding? Doc doubted that there had been.
Although, he recalled, the aliens had been basically very much like humans. They could even joke.
There had been one joking thing the original alien had said that had stuck inside his mind. And it had been a sort of silly thing, silly on the face of it, but it had bothered him.
The screen door banged behind Janet as she came out on the porch. She sat down in the glider.
"That was Martha Anderson," she said.
Doc chuckled to himself. Martha lived just five doors up the street and she and Janet saw one another a dozen times a day yet Martha had to phone.
"What did Martha want?" he asked.
Janet laughed. "She wanted help with rolls."
"You mean her famous rolls?"
"Yes. She couldn't remember for the life of her, how much yeast she used."
Doc chortled softly. "And those are the ones, I suppose, she wins all the prizes on at the county fair."
Janet said, crisply: "It's not so funny as you make it, Jason. It's easy to forget a thing like that. She does a lot of baking."
"Yes, I suppose you're right." said Doc.
He should be getting in, he told himself, and start reading in the journal. And yet he didn't want to. It was so pleasant sitting here — just sitting. It had been a long time since he could do much sitting.
And it was all right with him, of course, because he was getting old and close to worn out, but it wouldn't be all right with a younger doctor, one who still owed for his education and was just starting out. There was talk in the United Nations of urging all the legislative bodies to consider medical subsidies to keep the doctors going. For there still was need of them. Even with all diseases vanished, there still was need of them. It wouldn't do to let their ranks thin out, for there would be time and time again when they would be badly needed.
He'd been listening to the footsteps for quite a while, coming down the street, and now all at once they were turning in the gate.
He sat up straighter in his chair.
Maybe it was a patient, knowing he'd be home, coming in to see him.
"Why," said Janet, considerably surprised, "it is Mr. Gilbert."
It was Con Gilbert, sure enough.
"Good evening, Doc," said Con. "Good evening, Miz Kelly."
"Good evening," Janet said, getting up to go.
"No use of you to leave," Con said to her.
"I have some things to do," she told him. "I was just getting ready to go in."
Con came up the steps and sat down on the glider.
"Nice evening," he declared.
"It is all of that," said Doc.
"Nicest spring I've ever seen," said Con, working his way around to what he had to say.
"I was thinking that," said Doc. "It seems to me the lilacs never smelled so good before."
"Doc," said Con, "I figure I owe you quite a bit of money."
"You owe me some," said Doc.
"You got an idea how much it might be?"
"Not the faintest," Doc told him. "I never bothered to keep track of it."
"Figured it was a waste of time," said Con. "Figured I would never pay it."
"Something like that," Doc agreed.
"Been doctoring with you for a right long time," said Con.
"That's right, Con."
"I got three hundred here. You figure that might do it?"
"Let's put it this way. Con," said Doc. "I'd settle for a whole lot less."
"I guess, then, that sort of makes us even. Seems to me three hundred might be close to fair."
"If you say so," said Doc.
Con dug out his billfold, extracted a wad of bills and handed them across. Doc took them and folded them and stuffed them in his pocket.
"Thank you, Con," he said.
And suddenly he had a funny feeling, as if there were something he should know, as if there were something that he should be able to just reach out and grab.
But he couldn't, no matter how he tried, figure what it was.
Con got up and shuffled across the porch, heading for the steps.
"Be seeing you around," he said.
Doc jerked himself back to reality.
"Sure, Con. Be seeing you around. And thanks."
He sat in the chair, not rocking, and listened to Con going down the walk and out the gate and then down the street until there was only silence.
And if he ever was going to get at it, he'd have to go in now and start reading in the journal.
Although, more than likely, it was all damn foolishness. He'd probably never again need to know a thing out of any medic journal.
