further Achievements of Craig Kennedy Scientific Detective

to search for something apparently
to show them. Every one about them
was busy and, obedient to instruc-
tons from Donnelly, the store detec-
tives were in the background.
Kennedy was leaning forward
watching as intently as the distance
would permit. He reached over and
pressed the button near him.
After minute or TWO, the second
woman left, followed shortly by Mrs.
Willoughby herself. We hurried over
to the counter, and Kennedy seized
the box containing the kimberley
Queen" He examined it carefully.
A flaw in the paste jewel caught his
eye: .
There has been a substitution
here" he cried. See! The paste
Jewel which we used was hawless;
this has a little carbon spot here on
the side"
"One OF my men has been detailed
to follow each OF Them whispered
Donnelly. Shall | order them to
bring Mrs. Willoughby and Annie
Grayson to the superintendent ottice
and have them searched?
No" Craig almost shouted. That
would spoil everything. Don't make
a move until get at the real truth OF
this affair"
The case was becoming more than
nothing left for me to do but to wait
until Kennedy was ready TO accom-
pany DR.. Guthrie to the Willoughby
house. Several times he tried to reach
the doctor by telephone, but it was
not until the middle of the afternoon
that he succeeded.
81 shall be quite busy the rest Of
the afternoon, Walter" remarked
Craig, after he had made his appoint
ment with DR.. Guthrie. "If you will
meet me out at the Willoughbys' at
about eight o'clock, l shall be much
obliged to you"
DR.. Guthrie himself met me at the
door of the beautiful house on Wood
ridge avenue and with hearty hand
shake ushered me into the large room
in the right wing outside of which we
had placed the telegraphone two
nights before. 1t was the library.
We found Kennedy arranging an
instrument in the music room, which
adjoined the library. From what lit
should have said it was, in part at
least, galvanometer, one of those
instruments which register the in
tensity of minute electric currents.
AS nearly as could make out, in this
case the galvanometer was so ar
ranged that its action swung to one
side or the Other a little concave mir
ror hung from a framework which
rested on the table. Directly in front
of it was an electric light, and the re-
Fiction of the light was caught in the
mirror and focused by its concavity
upon a point to one side of the light.
Back of it was long strip of ground
glass and an arrow point, attached
to which was pen which touched a
| roll of paper.
On the large table in the library
itself Kennedy had placed in the CEN
ter a transverse board partition, high
enough so that two people seated
could see each others faces and con-
verse over it. but could not see each
partition were two metal domes
which were fixed to board set on the
table. On the other side, in addition
to space on which he could write,
Kennedy had arranged what looked
like one OF these new miniature NOV
ing-picture apparatuses operated by

be that. for directly in front of it.
hanging on the wall, in plain view of
any one seated on the side of the
table containing the metal domes, was
a large white sheet
The time for the experiment, what
ever its nature might be. had at last ar
rived, and Mr. Guthrie introduced Mr..
and Mrs. Willoughby to us as special
lists whom he had persuaded with
great difficulty to come down from
New York. Mr.. Willoughby he re-
quested to remain outside until after
the tests. She seemed perfectly calm
curiosity at the paraphernalia which
Kennedy had installed in her library.
Kennedy. who was putting some fin
ishing touches on it. was talking in a
low voice to reassure her.
IF you will sit here, please. Mrs
willoughby. and place your hands on
these two brass domes-there. that's
it. This is just a little arrangement
to test your nervous condition. DR.
Guthrie. who understands it. will take
his position outside in the music room
at that other tabl.. Walter. just
switch off that light. please.
Mrs. Willoughby. I may say that in
testing, say. the memory. We psycholo-
gists have recently developed two tests.
the event test, where something is made
to happen before a persons eyes and
later he is asked to describe II, and the
picture test, where a picture is shown
for a certain length of time, after which
the patient is also asked to describe
what was in the picture. I have en-
deavored to combine these two ideas by
using the moving-picture machine which
you see here. l am going to show three
reels of films"
As nearly as could make out Kennedy
his side of the table. As he worked over
the machine. which for the present
served to distract Mrs. willoushby's at
tention from herself. he was asking her a
series Of questions. From my position
I could see that by the light of the ma
chine he was recording both the ques-
tons and the answers. as we'll as the
