I took it, glanced at the screwed-up digits, stuck it into my pocket. Wexroth lit his pipe.

"And you really don't know what he wants of me?" I said.

He pushed his chair back into its proper position, then seated himself.

"I have no idea."

"Well," I said, "I feel better for having hit you, anyway. I'll see you in court."

I turned to go.

"I do not believe anyone has ever sought an order directing a university to rescind his degree," he said. "It should be interesting. In the meantime, I cannot say that I am unhappy to see an end to your dronehood."

"Save the celebration," I said. "I haven't finished yet."

"You and the Flying Dutchman," he muttered just before I slammed the door.

I had descended into an alleyway, up the block and around the corner from Merimee's place. Minutes later I was in a taxi and headed uptown. I got out at a clothing store, went in and bought a coat. It was chilly and I had left my jacket behind. From there, I walked to the hall. I had plenty of time and I wanted to determine, if possible, whether I was being followed.

I spent almost an hour in that big room where they kept the Rhennius machine. I wondered whether my other visit there had made the morning news. No matter. I paid attention to the movements of the viewers, to the positions of the four guards-there had only been two before-to the distances to the several entrances, to everything. I could not tell whether a new grille was yet in place on the other side of one of the overhead windows. Not that it really mattered. I had no intention of trying the same trick a second time. I was after something fast and different.

Musing, I went out to locate a sandwich and a beer, the latter for the benefit of any telepaths in the neighborhood. While I was about it, I kept checking and decided that I was not, at the moment, the subject of conspicuous scrutiny. I found a place, entered, ordered, settled down to eating and thought.

The idea hit me at the same time as a blast of cold air let in by a prospective diner. I rejected it immediately and continued with my beef and brew. But I could not come up with anything better.

So I resurrected it, cleaned it up and looked at it from every angle I could think of. Not much of an inspiration, but I was afraid it would have to do.

I figured the whole thing out, then realized that it might not work because of a side effect of the process itself. I beat back a moment's frustration, then started in again at the beginning. It wobbled on the brink of the ridiculous, the little things I had to cover because of something so minor.

I journeyed to the bus station and purchased a ticket home. I put it in my coat pocket. I bought a magazine and some chewing gum, had them put in a bag, disposed of the magazine, chewed the gum, kept the bag. Then I went looking for a bank, found one, went in and changed all my money into one-dollar bills, which I stuffed into the bag-one hundred fifteen in all.

Making my way back to the neighborhood of the hall, I searched out a restaurant with a coat-checking operation, left my coat and slipped back outside again. I used the wad of chewing gum to affix the coat receipt to the underside of a bench on which I sat for a while. Then I smoked a final cigarette and headed back for the hall, the bag of money in one hand, a single dollar bill palmed in the other.

Inside, I moved slowly, waiting for the crowd to achieve the proper density and distribution, rechecking my remembrance of air drafts on the opening and closing of the outer doors. I decided on the best position for the enterprise and worked my way toward it. By that time I had torn the bag down one side and was holding it together.

Around five minutes later the situation struck me as being about as close to ideal as it was likely to get. The crowd was effectively dense and the guards sufficiently distant. I listened to the by then standard "But what does it do?" and "They're not really certain," with an occasional "It's some kind of reversing thing. They're studying it" thrown in, until there was both a sharp draft and an appropriately large individual nearby.

I gave the guy an elbow in the ribs and a bit of a push. He, in turn, gave me a sample of Middle English-most people seem to think it is an Anglo-Saxonism, but I once looked it up in connection with a linguistics course-and he returned my shove.

I exaggerated my reaction, staggering back and bumping into another man while seeing to it that the bag came apart with a grand flourish high above my head.

"My money!" I screamed, springing forward then and leaping the guardrail. "My money!"

I ignored the murmurs, the shouts and the sudden scrambling that occurred behind me. I had triggered the alarm also, but the fact was not especially material at the moment. I was onto the platform and racing about it toward the place where the belt entered the central unit. I hoped that it was able to bear my weight.

I countered a bellowed "Get down from there!" with a couple of repetitions of "My money!" as I threw myself flat on the belt with what I hoped appeared a good dollar-chasing gesture, and I was borne surely and smoothly into the tunnel of the mobilaton

A tiny tingling sensation swept me from head to foot as I passed through the thing, and I experienced a momentary blurring of vision. This did not prevent my unfolding the dollar I had palmed, however, so that I emerged clenching it on high. I immediately rolled from the belt and, despite a wave of dizziness, jumped down from the platform and rushed back toward the crowd, trying to seem as if I still pursued my errant money, though none was then in sight.

"My money ... " I said as I climbed back over the rail and dropped to all fours.

"Here's some," an honest soul remarked, thrusting a fistful of bills down before my face.

ENO by ENO, a number of others were handed to me. Fortunately, the anticipation of this effect had been part of my earlier meditations, so that my reversed face showed no signs of surprise as I rose and thanked them. The only bill that looked normal to me was the one I had carried in my hand.

"Did you go through that thing?" a man asked.

"No. I went around behind it."

"Sure looked like you went through."

"No. I didn't."

As I accepted money and pretended to look for more, I did a rapid scan of the entire hall. The less honest folks with a few of my dollars in their pockets were heading out the doors, which were now in positions opposite those they had occupied when I had entered. But for this, too, had I prepared myself-at least intellectually. Now, though, I wondered. If was emotionally disconcerting, seeing the whole hall in reverse like that. And those departing were getting out without difficulty, for the guards were otherwise occupied: two were stuck in the crowd and two were collecting bills. I debated making a run for it.

At first, I had been all set to brazen it out with the guards or anyone else involved, matching nastiness or officiousness with a greater obnoxiousness over my missing money and an insistence that I had gone around rather than through the device. I had decided that I could stick to that format and sit out any consequences. After all, I did not believe that I had done anything grossly illegal- and no matter what happened, they could not take back the reversal.

Instead, they were nice about it. One of them got the alarm shut off and another shouted at everyone to turn in any money they had recovered as they departed the hall. Then two of them moved to cover the doors again, and the one who had done the hollering sought me with his eyes, found me and raised his voice once more: "Are you all right?"

"Yes," I said,

"I'm all right. But my money-"

"We're getting it! We're getting it!"

He plowed his way through to my side, laid his hand on my shoulder. I hastily pocketed the one bill that looked normal to me.
