else. As it was done yesterday the strong probability was
that we should find the words in yesterday's issue."

"So far as I can follow you, then, Mr. Holmes," said Sir Henry
Baskerville, "someone cut out this message with a scissors--"

"Nail-scissors," said Holmes. "You can see that it was a very
short-bladed scissors, since the cutter had to take two snips over 'keep
away.'"

"That is so. Someone, then, cut out the message with a pair of
short-bladed scissors, pasted it with paste--"

"Gum," said Holmes.

"With gum on to the paper. But I want to know why the word 'moor' should
have been written?"

"Because he could not find it in print. The other words were all simple
and might be found in any issue, but 'moor' would be less common."

"Why, of course, that would explain it. Have you read anything else in
this message, Mr. Holmes?"

"There are one or two indications, and yet the utmost pains have been
taken to remove all clues. The address, you observe is printed in rough
characters. But the Times is a paper which is seldom found in any hands
but those of the highly educated. We may take it, therefore, that
the letter was composed by an educated man who wished to pose as an
uneducated one, and his effort to conceal his own writing suggests that
that writing might be known, or come to be known, by you. Again, you
will observe that the words are not gummed on in an accurate line, but
that some are much higher than others. 'Life,' for example is quite out
of its proper place. That may point to carelessness or it may point to
agitation and hurry upon the part of the cutter. On the whole I incline
to the latter view, since the matter was evidently important, and it
is unlikely that the composer of such a letter would be careless. If he
were in a hurry it opens up the interesting question why he should be
in a hurry, since any letter posted up to early morning would reach
Sir Henry before he would leave his hotel. Did the composer fear an
interruption--and from whom?"

"We are coming now rather into the region of guesswork," said Dr.
Mortimer.

"Say, rather, into the region where we balance probabilities and choose
the most likely. It is the scientific use of the imagination, but we
have always some material basis on which to start our speculation. Now,
you would call it a guess, no doubt, but I am almost certain that this
address has been written in a hotel."

"How in the world can you say that?"

"If you
