Being a retired army officer was a political advantage in vote-getting among the more conservative and well-to-do citizens, and his record was O.K. for the other side of the fence. I'm not primarily concerned with vote-getting; what I liked about him was that, though he was liberal, he was tough-minded, which most liberals aren't. Most liberals believe that water runs downhill, but, praise God, it'll never reach the bottom.
Manning was not like that. He could see a logical necessity and act on it, no matter how unpleasant it might be.

We were in Manning's suite in the House Office Building, taking a little blow from that stormy first session of the Seventy-eighth Congress and trying to catch up on a mountain of correspondence, when the War Department called. Manning answered it himself.
I had to overhear, but then I was his secretary. "Yes," he said, "speaking. Very well, put him on. Oh . . . hello, General . . . Fine, thanks. Yourself?" Then there was a long silence. Presently, Manning said, "But I can't do that, General, I've got this job to take care of. . . . What's that? . . . Yes, who is to do my committee work and represent my district? . . . I think so." He glanced at his wrist watch. "I'll be right over."
He put down the phone, turned to me, and said, "Get your hat, John. We are going over to the War Department."
"So?" I said, complying.
"Yes," he said with a worried look, "the Chief of Staff thinks I ought to go back to duty." He set off at a brisk walk, with me hanging back to try to force him not to strain his bum heart. "It's impossible, of course." We grabbed a taxi from the stand in front of the office building and headed for the Department.
But it was possible, and Manning agreed to it, after the Chief of Staff presented his case. Manning had to be convinced, for there is no way on earth for anyone, even the President himself, to order a congressman to leave his post, even though he happens to be a member of the military service, too.
The Chief of Staff had anticipated the political difficulty and had been forehanded enough to have already dug up an opposition congressman with whom to pair Manning's vote for the duration of the emergency. This other congressman, the Honorable Joseph T. Brigham, was a reserve officer who wanted to go to duty himself—or was willing to; I never found out which. Being from the opposite political party, his vote in the House of Representatives could be permanently paired against Manning's and neither party would lose by the arrangement.
There was talk of leaving me in Washington to handle the political details of Manning's office, but Manning decided against it, judging that his other secretary could do that, and announced that I must go along as his adjutant. The Chief of Staff demurred, but Manning was in a position to insist, and the Chief had to give in.
A chief of staff can get things done in a hurry if he wants to. I was sworn in as a temporary officer before we left the building; before the day was out I was at the bank, signing a note to pay for the sloppy service uniforms the Army had adopted and to buy a dress uniform with a beautiful shiny belt—a dress outfit which, as it turned out, I was never to need.

We drove over into Maryland the next day and Manning took charge of the Federal nuclear research laboratory, known officially by the hush-hush title of War Department Special Defense Project No. 347. I didn't know a lot about physics and nothing about modern atomic physics, aside from the stuff you read in the Sunday supplements. Later, I picked up a smattering, mostly wrong, I suppose, from associating with the heavyweights with whom the laboratory was staffed.
Colonel Manning had taken an Army p.g. course at Massachusetts Tech and had received a master of science degree for a brilliant thesis on the mathematical theories of atomic structure. That was why the Army had to have him for this job. But that had been some years before; atomic theory had turned several cartwheels in the meantime; he admitted to me that he had to bone like the very devil to try to catch up to the point where he could begin to understand what his highbrow charges were talking about in their reports.
I think he overstated the degree of his ignorance; there was certainly no one else in the United States who could have done the job. It required a man who could direct and suggest research in a highly esoteric field, but who saw the problem from the standpoint of urgent military necessity. Left to themselves, the physicists would have reveled in the intellectual luxury of an unlimited research expense account, but, while they undoubtedly would have made major advances in human knowledge, they might never have developed anything of military usefulness, or the military possibilities of a discovery might be missed for years.
It's like this: It takes a smart dog to hunt birds, but it takes a hunter behind him to keep him from wasting time chasing rabbits. And the hunter needs to know nearly as much as the dog.
No derogatory reference to the scientists is intended—by no means! We had all the genius in the field that the United States could produce, men from Chicago, Columbia, Cornell, M.I.T., Cal Tech, Berkeley, every radiation laboratory in the country, as well as a couple of broad-A boys lent to us by the British. And they had every facility that ingenuity could think up and money could build. The five-hundred-ton cyclotron which had originally been intended for the University of California was there, and was already obsolete in the face of the new gadgets these brains had thought up, asked for, and been given. Canada supplied us with all the uranium we asked for—tons of the treacherous stuff—from Great Bear Lake, up near the Yukon, and the fractional-residues technique of separating uranium isotope 235 from the commoner isotope 238 had already been worked out, by the same team from Chicago that had worked up the earlier expensive mass spectrograph method.
Someone in the United States government had realized the terrific potentialities of uranium 235 quite early and, as far back as the summer of 1940, had rounded up every atomic research man in the country and had sworn them to silence. Atomic power, if ever developed, was planned to be a government monopoly, at least till the war was over. It might turn out to be the most incredibly powerful explosive ever dreamed of, and it might be the source of equally incredible power. In any case, with Hitler talking about secret weapons and shouting hoarse insults at democracies, the government planned to keep any new discoveries very close to the vest.
Hitler had lost the advantage of a first crack at the secret of uranium through not taking precautions. Dr. Hahn, the first man to break open the uranium atom, was a German. But one of his laboratory assistants had fled Germany to escape a pogrom. She came to this country, and told us about it.
We were searching, there in the laboratory in Maryland, for a way to use U235 in a controlled explosion. We had a vision of a one-ton bomb that would be a whole air raid in itself, a single explosion that would flatten out an entire industrial center. Dr. Ridpath, of Continental Tech, claimed that he could build such a bomb, but that he could not guarantee that it would not explode as soon as it was loaded and as for the force of the explosion—well, he did not believe his own figures; they ran out to too many ciphers.
The problem was, strangely enough, to find an explosive which would be weak enough to blow up only one county at a time, and stable enough to blow up only on request. If we could devise a really practical rocket fuel at the same time, one capable of driving a war rocket at a thousand miles an hour, or more, then we would be in a position to make most anybody say "uncle" to Uncle Sam.
We fiddled around with it all the rest of 1943 and well into 1944. The war in Europe and the troubles in Asia dragged on. After Italy folded up, England was able to release enough ships from her Mediterranean fleet to ease the blockade of the British Isles. With the help of the planes we could now send her regularly and with the additional over-age destroyers we let her have, England hung on somehow, digging in and taking more and more of her essential defense industries underground. Russia shifted her weight from side to side as usual, apparently with the policy of preventing either side from getting a sufficient advantage to bring the war to a successful conclusion. People were
beginning to speak of "permanent war."

I was killing time in the administrative office, trying to improve my typing—a lot of Manning's reports had to be typed by me personally—when the orderly on duty stepped in and announced Dr. Karst. I flipped the interoffice communicator. "Dr. Karst is here, chief. Can you see her?"
"Yes," he answered, through his end.
I told the orderly to show her in.
Estelle Karst was quite a remarkable old girl and, I suppose, the first woman ever to hold a commission in the Corps of Engineers. She was an M.D. as well as an Sc.D. and reminded me of the teacher I had had in fourth grade. I guess that was why I always stood up instinctively when she came into the room—I was afraid she might look at me and sniff. It couldn't have been her rank; we didn't bother much with rank.
She was dressed in white coveralls and a shop apron and had simply thrown a hooded cape over herself to come through the snow. I said, "Good morning, ma'am," and led her into Manning's office.
The Colonel greeted her with the urbanity that had made him such a success with women's clubs, seated her, and offered her a cigarette.
"I'm glad to see you, Major," he said. "I've been intending to drop around to your shop."
I knew what he was getting at; Dr. Karst's work had been primarily physiomedical; he wanted her to change the direction of her research to something more productive in a military sense.
"Don't call me 'major,'" she said tartly.
"Sorry, Doctor—"
"I came on business, and must get right back. And I presume you are a busy man, too. Colonel Manning, I need some help."
"That's what we are here for."
"Good. I've run into some snags in my research. I think that one of the men in Dr. Ridpath's department could help me, but Dr. Ridpath doesn't seem disposed to be cooperative."
"So? Well, I hardly like to go over the head of a departmental chief, but tell me about it; perhaps we can arrange it. Whom do you want?"
"I need Dr. Obre."
"The spectroscopist. Hm-m-m. I can understand Dr. Ridpath's reluctance, Dr. Karst, and I'm disposed to agree with him. After all, the high-explosives research is really our main show around here."
She bristled and I thought she was going to make him stay in after school at the very least. "Colonel Manning, do you realize the importance of artificial radioactives to modern medicine?"
"Why, I believe I do. Nevertheless, Doctor, our primary mission is to perfect a weapon which will serve as a safeguard to the whole country in time of war—"
She sniffed and went into action. "Weapons—fiddlesticks! Isn't there a medical corps in the Army? Isn't it more important to know how to heal men than to know how to blow them to bits? Colonel Manning, you're not a fit man to have charge of this project! You're a . . . you're a, a warmonger, that's what you are!"
I felt my ears turning red, but Manning never budged. He could have raised Cain with her, confined her to her quarters, maybe even have court-martialed her, but Manning isn't like that. He told me once that every time a man is court-martialed, it is a sure sign that some senior officer hasn't measured up to his job.
"I am sorry you feel that way, Doctor," he said mildly, "and I agree that my technical knowledge isn't what it might be. And, believe me, I do wish that healing were all we had to worry about. In any case, I have not refused your request. Let's walk over to your laboratory and see what the problem is. Likely there is some arrangement that can be made which will satisfy everybody."
He was already up and getting out his greatcoat. Her set mouth relaxed a trifle and she answered, "Very well. I'm sorry I spoke as I did."
"Not at all," he replied. "These are worrying times. Come along, John."
I trailed after them, stopping in the outer office to get my own coat and to stuff my notebook in a pocket.
By the time we had trudged through mushy snow the eighth of a mile to her lab they were talking about gardening!
Manning acknowledged the sentry's challenge with a wave of his hand and we entered the building. He started casually on into the inner lab, but Karst stopped him. "Armor first, Colonel."
We had trouble finding overshoes that would fit over Manning's boots, which he persisted in wearing, despite the new uniform regulations, and he wanted to omit the foot protection, but Karst would not hear of it. She called in a couple of her assistants who made jury-rigged moccasins out of some soft-lead sheeting.
The helmets were different from those used in the explosives lab, being fitted with inhalers. "What's this?" inquired Manning.
"Radioactive dust guard," she said. "It's absolutely essential."
We threaded a lead-lined meander and arrived at the workroom door which she opened by combination. I blinked at the sudden bright illumination and noticed the air was filled with little shiny motes.
"Hm-m-m—it is dusty," agreed Manning. "Isn't there some way of controlling that?" His voice sounded muffled from behind the dust mask.
"The last stage has to be exposed to air," explained Karst. "The hood gets most of it. We could control it, but it would mean a quite expensive new installation."
"No trouble about that. We're not on a budget, you know. It must be very annoying to have to work in a mask like this."
"It is," acknowledged Karst. "The kind of gear it would take would enable us to work without body armor, too. That would be a comfort."
I suddenly had a picture of the kind of thing these researchers put up with. I am a fair-sized man, yet I found that armor heavy to carry around. Estelle Karst was a small woman, yet she was willing to work maybe fourteen hours, day after day, in an outfit which was about as comfortable as a diving suit. But she had not complained.
Not all the heroes are in the headlines. These radiation experts not only ran the chance of cancer and nasty radioaction burns, but the men stood a chance of damaging their germ plasm and then having their wives present them with something horrid in the way of offspring—no chin, for example, and long hairy ears. Nevertheless, they went right ahead and never seemed to get irritated unless something held up their work.
Dr. Karst was past the age when she would be likely to be concerned personally about progeny, but the principle applies.
I wandered around, looking at the unlikely apparatus she used to get her results, fascinated as always by my failure to recognize much that reminded me of the physics laboratory I had known when I was an undergraduate, and being careful not to touch anything. Karst started explaining to Manning what she was doing and why, but I knew that it was useless for me to try to follow that technical stuff. If Manning wanted notes, he would dictate them. My attention was caught by a big boxlike contraption in one corner of the room. It had a hopperlike gadget on one side and I could hear a sound from it like the whirring of a fan with a background of running water. It intrigued me.
I moved back to the neighborhood of Dr. Karst and the Colonel and heard her saying, "The problem amounts to this, Colonel: I am getting a much more highly radioactive end product than I want, but there is considerable variation in the half-life of otherwise equivalent samples. That suggests to me that I am using a mixture of isotopes, but I haven't been able to prove it. And frankly, I do not know enough about that end of the field to be sure of sufficient refinement in my methods. I need Dr. Obre's help on that."
I think those were her words, but I may not be doing her justice, not being a physicist. I understood the part about "half-life." All radioactive materials keep right on radiating until they turn into something else, which takes theoretically forever. As a matter of practice their periods, or "lives," are described in terms of how long it takes the original radiation to drop to one-half strength. That time is called a "half-life" and each radioactive isotope of an element has its own specific characteristic half-lifetime.
One of the staff—I forget which one—told me once that any form of matter can be considered as radioactive in some degree; it's a question of intensity and period, or half
-life.
"I'll talk to Dr. Ridpath," Manning answered her, "and see what can be arranged. In the meantime you might draw up plans for what you want to reequip your laboratory."
"Thank you, Colonel."
I could see that Manning was about ready to leave, having pacified her; I was still curious about the big box that gave out the odd noises.
"May I ask what that is, Doctor?"
"Oh, that? That's an air conditioner."
"Odd-looking one. I've never seen one like it."
"It's not to condition the air of this room. It's to remove the radioactive dust before the exhaust air goes outdoors. We wash the dust out of the foul air."
"Where does the water go?"
"Down the drain. Out into the bay eventually, I suppose."
I tried to snap my fingers, which was impossible because of the lead mittens. "That accounts for it, Colonel!"
"Accounts for what?"
"Accounts for those accusing notes we've been getting from the Bureau of Fisheries. This poisonous dust is being carried out into Chesapeake Bay and is killing the fish."
Manning turned to Karst. "Do you think that possible, Doctor?"
I could see her brows draw together through the window in her helmet. "I hadn't thought about it," she admitted. "I'd have to do some figuring on the possible concentrations before I could give you a definite answer. But it is possible—yes. However," she added anxiously, "it would be simple enough to divert this drain to a sink hole of some sort."
"Hm-m-m—yes." He did not say anything for some minutes, simply stood there, looking at the box.
Presently he said, "This dust is pretty lethal?"
"Quite lethal, Colonel." There was another long silence.
At last I gathered he had made up his mind about something for he said decisively, "I am going to see to it that you get Obre's assistance, Doctor—"
