Above tho hubub. inside now. we
could hear loud gong sounding In

through the passageways. Shouts

were off now. with a good start

of Montrose and every other town
about US were being informed OF the
escape. They were required by the
law to render all possible assistance.
and. as the country boasted several In
claire. an attempt to escape was not an
unusual occurrence.
The post road by which we had como
was therefore impossible. and Kennedy
swung up into the country. in the hope
of throwing Off pursuit long enough
to give US better chance.
Take the wheel. Walter" he NUT
tered. "Tll tell you what turns to
make. We must get to the state line
Of New York without being stopped.
We can beat almost any car. But that
is not enough. telephone message

the car as Kennedy climbed over the

Mrs. Cranston was sitting. he hastily
adjusted the peculiar apparatus.
Sounds at night are very hard to

tinued to watch the instrument before
him.
What is It? I whispered.
"A phonometer." he replied. 'It was
invented to measure the intensity of
SOUND. But 1t Is much moro valuable
as an instrument that tells with pre-
cfsion from what direction a sound
comes. 1t needs only a small dry bat
terry and can be carried around easily.
The sound enters the two horns OF the
phonometer. is focused at the neck and
strikes on delicate diaphragm, behind
which is a needle. The diaphragm vi

at right angles to the direction from

l lift my head, I am looking straight
toward the source of the sound. I can
tell its direction to a few degrees"
l looked through it myself to see how
sound was visualized by light.
Hush cautioned Kennedy.
Down on the main road We could see
a car pass along slowly in the direction
of Montrose. from which we had come.
Without the phonometer to warn US, IL
must inevitably have met US and block
ed our escape over the road ahead.
The danger passed. on we sped. Five
minutes. l calculated. and We should
cross the state line to New York and
safety.
We had been going along nicely when,
Bang" came a loud report back of US.

We climbed out of the car and had
the shoe Off in short order.
.Look," cried Janet Cranston, In q
frightened voice, from the back of the
car.
The light of the phonometer had
flashed up. A car was following us.

us over to the very edge of the road.
