that any stranger could have been there. Then he suggested that his
tailor might have called, and she agreed that it was so. But when an
hour or two later he interviewed his tailor, he, on his part, said he
had not been near the place. Graves consequently deduced that he was
being followed.

The knowledge that you are being watched, and you don't know by whom,
gives, I can assure you, a very jumpy feeling--especially when you
know you are guilty.

I can speak feelingly from more than one experience of it, since I
have myself been employed on this form of scouting in peace time.


OFFICER AGENTS.

It is generally difficult to find ordinary spies who are also
sufficiently imbued with technical knowledge to be of use in gaining
naval or military details. Consequently officers are often employed
to obtain such information in peace time as well as in the theatre of
action in war.

But with them, and especially with those of Germany, it is not easy to
find men who are sufficiently good actors, or who can disguise their
appearance so well as to evade suspicion. Very many of these have
visited our shores during the past few years, but they have generally
been noticed, watched, and followed, and from the line taken by
them in their reconnaissance it has been easy to deduce the kind of
operations contemplated in their plans.
