"Which train?" he asked me sourly. "You've missed three already."

"I'm waiting for a special train, officer."

"Then please go and wait in the bar, Mr. Cornell."

"Okay. I'm sorry I caused you any trouble, but I've a bit of a personal problem. It isn't illegal."

"Anything that involves taking a perceptive dig at the U.S. Mail is illegal," said the policeman. "Personal or not, it's out. So either you stop digging or else."

I left. There was no sense in arguing with the cop. I'd just end up short. So I went to the bar and I found out why he'd recommended it. It was in a faintly-dead area, hazy enough to prevent me from taking a squint at the baggage section. I had a couple of fast ones, but I couldn't stand the suspense of not knowing when my letter might take off without me.

Since I'd also pushed my loitering-luck I gave up. The only thing I could hope for was that the sealed forwarding address had been made out at that little town near the Harrisons and hadn't been moved. So I went and took a train that carried no mail.

It made my life hard. I had to wander around that tank town for hours, keeping a blanket-watch on the post office for either the income or the outgo of my precious hunk of mail. I caught some hard eyes from the local yokels but eventually I discovered that my luck was with me.

A fast train whiffled through the town and they baggage-hooked a mailbag off the car at about a hundred and fifty per. I found out that the next stop of that train was Albany. I'd have been out of luck if I'd hoped to ride with the bag.

Then came another period of haunting that d.i.n.ky post office (I've mentioned before that it was in a dead area, so I couldn't watch the insides, only the exits) until at long last I perceived my favorite bit of mail emerging in another bag. It was carted to the railroad station and hung up on another pick-up hook. I bought a ticket back to New York and sat on a bench near the hook, probing into the bag as hard as my sense of perception could dig.

I cursed the whole world. The bag was merely labelled "Forwarding Mail"

in letters that could be seen at ninety feet. My own letter, of course, I could read very well, to every dotted 'i' and crossed 't' and the st.i.tching in Catherine's little kerchief. But I could not make out the address printed on the form that was pasted across the front of the letter itself.

As I sat there trying to probe that sealed address, a fast train came along and scooped the bag off the hook.

I caught the next train. I swore and I squirmed and I groaned because that train stopped at every wide spot in the road, paused to take on milk, swap cars, and generally tried to see how long it could take to make a run of some forty miles. This was Fate. Naturally, any train that stopped at my rattle burg would also stop at every other point along the road where some pioneer had stopped to toss a beer bottle off of his covered wagon.

At long last I returned to Pennsylvania Station just in time to perceive my letter being loaded on a conveyor for LaGuardia.

Then the same d.a.m.ned policeman collared me.

"This is it," he said.

"Now see here, officer. I--"

"Will you come quietly, Mr. Cornell? Or shall I put the big arm on you?"

"For what?"

"You've been violating the 'Disclosure' section of the Federal Communications Act, and I know it."

"Now look, officer, I said this was not illegal."

"I'm not an idiot, Cornell!" I noted uncomfortably that he had dropped the formal address. "You have been trailing a specific piece of mail with the express purpose of finding out where it is going. Since its destination is a sealed forwarding address, your attempt to determine this destination is a violation of the act." He eyed me coldly as if to dare me to deny it. "Now," he finished, "Shall I read you chapter and verse?"

He had me cold. The 'Disclosure' Act was an old ruling that any transmission must not be used for the benefit of any handler. When Rhine came along, 'Disclosure' Act was extended to everything.

"Look officer, it's my girl," hoping that would make a difference.

"I know that," he told me flatly. "Which is why I'm not running you in.

I'm just telling you to lay off. Your girl went away and left you a sealed forwarding address. Maybe she doesn't want to see you again."

"She's sick," I said.

"Maybe her family thinks you made her sick. Now stop it and go away. And if I ever find you trying to dig the mail again, you'll dig iron bars.

Now scat!"

He urged me towards the outside of the station like a sheep-dog hazing his flock. I took a cab to LaGuardia, even though it was not as fast as the subway. I was glad to be out of his presence.

I connected with my letter again at LaGuardia. It was being loaded aboard a DC-16 headed for Chicago, Denver, Los Angeles, Hawaii, and Manila. I didn't know how far it was going so I bought a ticket for the route with my travel card and I got aboard just ahead of the closing door.

My bit of mail was in the compartment below me, and in the hour travel time to Chicago, I found out that Chicago was the destination for the mailbag, although the superscript on the letter was still hazy.

I followed the bag off the plane at Chicago and stopped long enough to cancel the rest of my ticket. There was no use wasting the money for the unused fare from Chicago to Manila. I rode into the city in a combination bus-truck less than six feet from my little point-of-interest. During the ride I managed to dig the superscript.

It forwarded the letter to Ladysmith, Wisconsin, and from there to a rural route that I couldn't understand although I got the number.

Then I went back to Midway Airport and found to my disgust that the Chicago Airport did not have a bar. I dug into this oddity for a moment until I found out that the Chicago Airport was built on Public School Property and that according to law, they couldn't sell anything harder than soda pop within three hundred feet of public school property, no matter who rented it. So I dawdled in the bar across Cicero Avenue until plane time, and took an old propeller-driven Convair to Eau Claire on a daisy-clipping ride that stopped at every wide spot on the course. From Eau Claire the mail bag took off in the antediluvian Convair but I took off by train because the bag was scheduled to be dropped by guided glider into Ladysmith.

At Ladysmith I rented a car, checked the rural routes, and took off about the same time as my significant hunk of mail.

Nine miles from Ladysmith is a flagstop called Bruce, and not far from Bruce there is a body of water slightly larger than a duck pond called Caley Lake.

A backroad, decorated with ornamental metal signs, led me from Bruce, Wisconsin, to Caley Lake, where the road signs showed a missing spoke.

I turned in, feeling like Ferdinand Magellan must have felt when he finally made his pa.s.sage through the Strait to discover the open sea that lay beyond the New World. I had done a fine job of tailing and I wanted someone to pin a leather medal on me. The side road wound in and out for a few hundred yards, and then I saw Phillip Harrison.

He was poking a long tool into the guts of an automatic pump, built to lift water from a deep well into a water tower about forty feet tall. He did not notice my arrival until I stopped my rented car beside him and said:

"Being a mechanical engineer and an esper, Phil, I can tell you that you have a--"

"A worn gasket seal," he said. "It doesn't take an esper engineer to figure it out. How the heck did you find us?"

"Out in your mailbox there is a letter," I told him. "I came with it."

He eyed me humorously. "How much postage did you cost? Or did you come second cla.s.s mail?"

I was not sure that I cared for the inference, but Phillip was kidding me by the half-smile on his face. I asked, "Phil, please tell me--what is going on?"

His half-smile faded. He shook his head unhappily as he said, "Why can't you leave well-enough alone?"

My feelings welled up and I blew my scalp. "Let well enough alone?" I roared. "I'm pushed from pillar to post by everybody. You steal my girl.

I'm in hokus with the cops, and then you tell me that I'm to stay--"

"Up the proverbial estuary lacking the customary means of locomotion,"

he finished with a smile.

I couldn't see the humor in it. "Yeah," I drawled humorlessly.
