Further Achievements of Craig Kennedy Scientific Detective

ing. l found him engrossed in work
at the laboratory.
"Just in time to see whether I'm
right in my guess about the illness OF
Brixton," he remarked, scarcely look
ing up at me.
He had taken flask with rubber
stopper Through one hole in it was
fitted long funnel; through another
ran a glass tube, connecting with a
large U-shaped drying tube filled
with calcium chloride, which in turn
connected with long open tube with
an upturned end.
Into the flask Craig dropped some
pure graduated zinc coated with plat
mum. Then he covered it with dilute
sulphuric acid through the funnel
tube. That forms hydrogen gas" he
explained, (which passes through the
drying tube and the ignition tube.
Wait moment until all the air is
expelled from the tubes"
He lighted a match and touched it
to the open upturned end. The hydro
gen, now escaping freely, was ignited

Next, he took the little piece OF
wallpaper ] had seen him tear off in
the den, scraped off some powder
from it. dissolved it, and poured it
into the funnel tube.
Almost Immediately the pale, blush
flame turned to BLUSH white, and
white fumes were formed In the ig-
milton tube sort of metallic deposit
appeared. Quickly he made one test
after another. | shifted There was an
unmistakable smell of garlic in the
air.
"Arseniureted hydrogen" comment
ed Craig. This is the Marsh test for
arsenic That wallpaper in Brixton's
den has been loaded down with ar

Schweinfurth green, which is aceto-
arsenite of copper Every minute he is
there he is breathing arseniureted hy-
drogen. | thought | knew the smell
the moment I got a Whit of it. Be-
sides, | could tell by the jaundiced
look of his face that he was being
poisoned. His liver was out of order,
and arsenic seems to accumulate in
the liver"
We lost no time in returning again
to Woodrock late that afternoon.
Craig fastened to warn Brixton of
his peril from the contaminated at
mosphere of the den, and at once a
servant was set to work with a
vacuum cleaner.
Carefully Craig reconnoitered the
basement where the eavesdropping
storeroom was situated. Finding it
deserted, he quickly set to work con-
Meeting the two wires of the general
household telephone with what look
ed very much like a seamless iron
tube, perhaps six inches long and
three inches in diameter. Then he
connected the tube also with the pri-
vate wire OF Brixton in a similar man.

This is special repeating coil of
high efficiency" he explained in an
swer to my inquiry. at is absolutely
turns, and everything. I shall run this
third line from the coil into Brixton's
den, and then. if you like, you can
accompany me on a little excursion
down to the village where l am going
to install another similar coil be-
tween the two lines at the local tele-
phone central station opposite the
railroad"
Brixton met us about eight o'clock
that night in his now renovated den.
Kennedy had brought with him a
rectangular box Of oak, in one of the
large faces of which were two square
holes. AS he replaced the black CAM
era-like box OF the detectaphone with
this oak box he remarked: This is
an intercommunicating telephone ar
rangement of the detectaphone. You
see, it is more sensitive than anything
of the sort ever made before. The
arrangement of these little square
holes is such as to make them act as
horns or magnifers of double re-
ceiver. We can all hear at once what
is going on by using this machine"
We had not been waiting long be-
fore a peculiar noise seemed to issue
from the detectaphone. 1t was as
though door had been opened and
shut hastily. Some one had evident
ly entered the storeroom. A voice
called up the railroad station and ask
ed for Michael kronski, Count Wacht-
mann's chauffeur.
at is the voice | heard last night"
exclaimed Brixton. by the Lord
Harry, do you know, it is Janeff. the
engineer who has charge Of the steam
heating, the electric bells. and every
thing of the sort around the place.
My own engineer-I'll land the fell

Kennedy raised his hand. LET us
hear what he has to say remon-
strated Craig calmly. az suppose you
have wondered why didn't just go
down there last night and grab the
fellow. Well, you see now. 1t is my
invariablc rule to get the man high
est up. This fellow is only one tool
Arrest him, and as likely as not we
should allow the big criminal to es-
cape"
Hello, Kronski" came over the
detcctaphone. This is Janeff. How
are things going?"
Wachtmann's chauffeur must have
answered that everything was all
right.
"You knew that they had discover
ed the poisoned wallpaper" asked
Janeff
A long parley followed. Finally,
Janeff repeated what apparently had
been his instructions. Now, let me
see," he said. you want me to stay
here until the last minute sojthat l

it is the nine o'clock train she is due
