absolutely black.

'A horror of this great darkness came on me. The cold, that smote
to my marrow, and the pain I felt in breathing, overcame me. I
shivered, and a deadly nausea seized me. Then like a red-hot bow
in the sky appeared the edge of the sun. I got off the machine to
recover myself. I felt giddy and incapable of facing the return
journey. As I stood sick and confused I saw again the moving thing
upon the shoal--there was no mistake now that it was a moving
thing--against the red water of the sea. It was a round thing, the
size of a football perhaps, or, it may be, bigger, and tentacles
trailed down from it; it seemed black against the weltering
blood-red water, and it was hopping fitfully about. Then I felt I
was fainting. But a terrible dread of lying helpless in that remote
and awful twilight sustained me while I clambered upon the saddle.

'So I came back. For a long time I must have been insensible upon
the machine. The blinking succession of the days and nights was
resumed, the sun got golden again, the sky blue. I breathed with
greater freedom. The fluctuating contours of the land ebbed and
flowed. The hands spun backward upon the dials. At last I saw again
the dim shadows of houses, the evidences of decadent humanity.
These, too, changed and passed, and others came. Presently, when the
million dial was at zero, I slackened speed. I began to recognize
our own petty and familiar architecture, the thousands hand ran back
to the starting-point, the night and day flapped slower and slower.
Then the old walls of the laboratory came round me. Very gently,
now, I slowed the mechanism down.

'I saw one little thing that seemed odd to me. I think I have told
you that when I set out, before my velocity became very high, Mrs.
Watchett had walked across the room, travelling, as it seemed to me,
like a rocket. As I returned, I passed again across that minute when
she traversed the laboratory. But now her every motion appeared to
be the exact inversion of her previous ones. The door at the lower
end opened, and she glided quietly up the laboratory, back foremost,
and disappeared behind the door by which she had previously entered.
Just before that I seemed to see Hillyer for a moment; but he passed
like a flash.

'Then I stopped the machine, and saw about me again the old familiar
laboratory, my tools, my appliances just as I had left them. I got
off the thing very shakily, and sat down upon my ben
