7 world. Every ship. every amateur
station, on any wave length-the
wireless world is open to me here."
That's it," cried Glenn. Let me
go with you"
NO. Doctor, put him up where
he can get over this quick. I'll need
you, boy, tomorrow, need you bad
/ ly. Get in shape"
Glenn obeyed with, for him, good
grace and in a moment. with the
full story, Garrick and Dick were
/ speeding to Rock Ledge. Broad
casting by the police-for stolen
cars-missing peopIe-all sorts of
] crimes-is getting to be a greater
| success every day." cried Garrick,
/ trying to pump enthusiasm into the
crushed Dick and with success
| Guy, I'm dub. In my own line,
/ too. Never thought of the Rock
/ Ledge broadcasting station. OF
! course. XYXZ can do it,"
There were no formalities neces-
/ sary at the Radio Central for a com
! bination like Garrick and Dick, who
was a constant frequenter of the
place.
They soon found themselves in
small room, quite plain except for
the draceries that were artistically
arranged to hide the bare walls
There were a few plants and flow
ers about, also. At one end stood
beautiful piano of the reproducing
variety. Some of the best known
artists hai il reality played on ii;
all had played on it through the
perforated paper rolls. There were
monographs of all the standard
weIl-known makes and on the other
side an automatic organ.
A small table with a silk-shaded
lamp added a touch of nominees
and there were a few, not many,
deep easy chairs.
But the most important piece of
furniture which interested Garrick
more than anything else, as the at
tendant conducted them in, was the
cabinet containing little lamps and
plenty of switches and wiring, COM
priSing what Is known as the modu-
lating equipment. 1t was a wooden
framework covered with copper
screening to prevent the delicate
apparatus from being disturbed by
electrical and magnetic influences
within the room itself. Various con- |
ductors connecting up the cabinet |
and the transmitter were sheathed |
in beautiful, bright an neat woven !
copper sleeves or tubes for the |
same reason.
There's the little trasmitter,
mounted on that portable stand" ,
transmitter, proper, is located in a |
little room under the roof overhead. |
There are a couple of operators, for /
it contains all the elements of actual |
transmission When this studio is
to broadcast it is connected by this
switch over here with the radio
station upstairs. Here's wire
telephone to it, too"
Garrick hardly needed to be told.
He had seen it once before, the
radio telephone transmitter which
of a cabinet closed in by
iron grill work to prevent damage
to the delicate vacuum tubes, five
of them for the normal operation.
At the extreme end of a long oper-
ating desk or table was the trans
mitter. On the table were ordinary
telephone instruments, radio appa-
ratuS, a receiving set with ampli-
fers, telephone head sets and a loud
speaking device by which the oper-
ators could hear the speech or
music rendered downstairs. only
here actuated by the long distance
receiving set
Now, here's teh phoetron the
dish basin some people call it."
pointed out the attendant, who had
been looking at his watch and
to determine when would
De the best time to broadcast the
alarm Garrick had impressed ON
lis mind.
Garrick looked curiously at the
little hole in a cylinder dangling
rom an adjustable stand in front

The minutes seemed eternity to
Dick. Would it never be possible
or GarriCk to soar on wings of
wireless to the succor of Ruth and
IRA?
. 'AlI set?" The attendant called.

The attendant nodded to Garrick '

Slowly and distinctly Garrick /.
