excitement, fever. I don't know what you've got. There's something very
queer about the look of your eyes."

"Come," said I, "you can't put us all to bed, you know. You had better
listen and hear the symptoms in full."

The Doctor shrugged his shoulders, but he listened to me patiently. He
did not believe a word of the story, that was clear; but he heard it all
from beginning to end. "My dear fellow," he said, "the boy told me just
the same. It's an epidemic. When one person falls a victim to this sort
of thing, it's as safe as can be,--there's always two or three."

"Then how do you account for it?" I said.

"Oh, account for it!--that's a different matter; there's no accounting
for the freaks our brains are subject to. If it's delusion, if it's some
trick of the echoes or the winds,--some phonetic disturbance or other--"

"Come with me to-night, and judge for yourself," I said.

Upon this he laughed aloud, then said, "That's not such a bad idea; but
it would ruin me forever if it were known that John Simson was
ghost-hunting."

"There it is," said I; "you dart down on us who are unlearned with your
phonetic disturbances, but you daren't examine what the thing really is
for fear of being laughed at. That's science!"

"It's not science,--it's common-sense," said the Doctor. "The thing has
delusion on the front of it. It is encouraging an unwholesome tendency

shouldn't believe."

"I should have said so yesterday; and I don't want you to be convinced or
to believe," said I. "If you prove it to be a delusion, I shall be very
much obliged to you for one. Come; somebody must go with me."

"You are cool," said the Doctor. "You've disabled this poor fellow of
yours, and made him--on that point--a lunatic for life; and now you want
to disable me. But, for once, I'll do it. To save appearance, if you'll
give me a bed, I'll come over after my last rounds."

It was agreed that I should meet him at the gate, and that we should
visit the scene of last night's occurrences before we came to the house,
so that nobody might be the wiser. It was scarcely possible to hope that
the cause of Bagley's sudden illness should not somehow steal into the
knowledge of the servants at least, and it was better that all should be
done as quietly as possible. The day seemed to me a very long one. I had
to spend a certain part of it with Roland, which was a terrible orde
