"But Brett," I said, "there are one or two things I want to ask you.
About your return voyage--for instance----"
It was mid-afternoon. Brett, thoroughly rested, was wholly himself
again. Quiet, composed and smiling, but very determined; even a little
grim. And I think he was a bit ashamed of the sudden, almost querulous
way in which he had terminated his narrative and left us there in the
observation room at dawn. He had had his sleep now; and had been alone
for an hour with his father. Martt and Frannie had been called to them;
I--an outsider--was not asked, or wanted. What took place there behind
the closed door of the study, it was not for me to ask. But when they
came out I knew that Brett had won. A questionable victory, for old Dr.
Gryce was visibly broken; Frannie--pale and upon the verge of tears;
and Martt for a time a trifle sullen; resentful that he was to be left
behind. I think it hurt Brett--this fear he was bringing upon those
he loved. But he was very determined; convinced that it was the right
thing for him to do.
"I start back tonight, Frank," he told me soberly as he emerged from
the study.
"Oh," I said. "For how long will you be gone this time?"
He hesitated. A look, which even now my memory fails to interpret,
came to him. Then he smiled. "I don't know. But remember, Frank, I can
return--with only those limitations the Almighty enforces--I can return
to any point of earth-Time I wish. As you will live it--well, I shall
aim to return here within a month."
It was then I asked him about the return voyage he and Martt had just
made. "Brett, I've been wondering--did our aural ray guide you back?"
"Yes," he said. "On the voyage back, the first thing I did was to put
the vehicle back through Time to a chosen instant at which I wished
to arrive here on earth. When that was done, I held that instant
always. We could not see the aural ray going out--when we looked
back for it--for two reasons. One: Our Time had run far into earth's
Future, and the ray was non-existent. The other: Even had we taken the
proper Time-point, we were outrunning the light-rays themselves. In
space, I mean, the aural ray left earth only with the speed of light.
Our velocity exceeded that. You see? But on the return voyage we
encountered the ray as we came in. A mere flash over the sky; but its
characteristic color-bands guided us."
What he said about outrunning the light-rays made me think of the
myrdoscope, the image of that girl--which they had received here on
earth before the voyage--that image had crossed a space 5,000,000
light-years in extent. But when I mentioned it, he explained:
"The myrdal rays are not light, Frank, but only akin to it. Their
velocity--why, light beside them is a laggard. We have no way of
computing the velocity of the myrdal rays. But over a finite distance
such as five million light-years--for practical purposes it is
instantaneous. . .
"I wanted to tell you--I was confused last night--I meant to explain
that coming back I used quite a different method from the outward trip.
I chanced a disturbance of some of those outlying starry universes,
and when we left the Inner Surface, I made the vehicle larger instead
of smaller. The void of Space shrank until about us the universes were
clustered like little patches of mist--tiny areas of glowing star-dust.
I saw our own, with its spectrum of the aural ray, quite readily. And
had reached it with a voyage of a few hours--and then reduced our size."
"And your Time," I said. "Brett, I didn't see the vehicle until it was
almost entering the earth's atmosphere. And--just for an instant--it
seemed not solid, but like a vague gray ghost. Then suddenly it
materialized."
He smiled and nodded. "Yes. That was when I took the earth's normal
Time-rate."
The family joined us; we said no more. And that night Brett left us
for his solitary voyage. I would not set down here in detail those
last good-byes. Emotion repressed--it was what was not said that held
a pathos I shall never forget. An outward attempt at lightness. Martt
laughed, "Give my love to Leela." And Frannie said, "You tell her I'm
jealous because she's so beautiful."
Just before Brett closed the door of the vehicle, Dr. Gryce spoke--the
only thing he had said for an hour past.
"You'll be sure to come back, Brett? Within the month, lad?"
"Oh, yes. Yes, Father dear."
"Well--good-bye. . ."
Good-bye! I can think of no sadder word for human tongue to frame.
