times follow his quarry into the buih.
ing. In that case the white and pinL
confetti tells the story. The paper fray.
ments are entirely inconspicuous, and
as for chalk marks, they are not noticed
by any one. Many a detective chaIk
mark has been taken for the idle prank
of some strolling boy. The color Of III.
chalk differs with the days of the week
with some operatives. The person WIN
last follows up the marks does what h.
can with a wet handkerchief to oblit.
crate them, and by standing with
his back to the wall for a moment \.
can do so very deity without arousinv
the slightest attention on the part Of
passers-by.
When the chalk mark is missing the
second or relay sleuth is convinced that
his predecessor on the case or the pres.
ent incumbent of the case is in the block.
He walks back after making certain
that he did not take car at that point
which would be revealed by the confetti
on the ground. If the object and tho
trailer are in the block they will be soon
seen or flock of confetti will show near
the entrance.
These means are not always availa.
BILE, especially since the advent of the
automobile. Yet the turns of the road
can be easily determined if both the Oh.
ject and the trailer use machines.
This difficulty has been overcome BY
the fact that few licensed chauffeur
dare to refuse the cooperation with the
police and none of the out-of.town
drivers can be long unknown 20 authori.
ties. If the object drives his own car
he is automatically traced by his license
and the garage arrangements that de.
mand registration of every foreign car.
Yet if the object drives his own car
about town all day the only way in
which he can be observed is by trailing
or preceding in another.
With the small piece of mirror used
as periscope the cleverest men precede
instead of follow their objects. In stree!
cars, for instance, the trailer often sits
in front of the object and observes his
motions with the little piece of glass
The apparent adjusting of pair Of
spectacles or the twirling of mustache
will enable the trailer to observe the per.
son sitting behind, when the small mir.
ror is concealed in the palm of the hand
Few persons believe that a person
walking ahead or sitting in front Of
them are following" them, and many
are thrown completely off their guard |
Another important factor is the tele |
phone espionage. Few secret messages
can now be sent by suspected person F.
through the hotel telephones. Every
word is usually recorded by Shorthand
operators that are let in on the line and
even the scraps of torn paper from the
waste baskets of the rooms of suspected
guests are pasted together on trans
parent paper and turned over to the
police. Names in hat bands, taIon
labels in clothes and other detals
are observed and reported, and woe b
to the one who registers under q di1er
ent name than that Of the labels In Oh
coat. n
Where there is the slightest inconw
;ty there will be the most strenuous H I
tenn of espionage until the suspect
either in the tolls or the authorities |"
satisfied that he or she is harmless.
