Radio Grips Them Hard.
The most important event Of the op-
ening night was the showing of e. F.
Glavin's wi. eless controlled automobile.
Mr.. Glavn lives in Tuckahoe and has
been tinkering with radio apparatus
| ever since before the war He advised
| people last night to steer clear of radio
unless they wanted it to take hold of
| them with the relentless strength Of an
obsession.
"You can't think about anything else,
once you get started with radio" said
\ Mr.. Glavin.
i Mr. Glavin's automobile Is shaped like
a torpedo. 1t Is feet inches long and
weighs l50 pounds. 1t Is run by a stor-
i age battery. 1t is controlled by elec-
| trical devices and each movement of
the car is ordered by a separate cleo
| trio current. The different switches are
! operated by radio. 1t is on the same
/ principle as the wireless controlled tor
| pedo. 1t has nine different circuits for
controlling the reverse. forward. left.
| right and other movements. and is oper-
/ ated by 1856 meter wave length.
/ space was cleared through the
| crowd when Mr.. Glavin began his DEM
| onstraton. He stood at the radio ap-
paratus and backed the car out of its
| small garage, ran 1t across the floor.
turning 1t around. and then put IL back
into the garage. He will demonstrate 1t
again this afternoon inside a roped
| square which he is going to put up to
keep the people back.
/ Recalls Farmers Dreams.
| When he was asked about the practf-
| cal peace time uses of his radio con-
trolled automobile. Mr.. Glavin said he
| couldn't see much use OF IL at all. unless
! 1t could be developed sufficiently to
] enable farmers In the level country to
| control their farm implements. There
Is dream-merely dream--of an era
when the farmers of the middle West
will sit on their front porches controlling
their tractors and other farm imple-
ments by wireless. The idea, as Mr.
Glavin pointed out, has many imagina-
tive possibilities.
| Army was one of the fifty exhibitors.
| The army exhibition was in charge of
| Charles McBrearty. a radio engineer.
who said that the army radio stations
established throughout the country had
cut down telephone and telegraph bills
to point where they are "joke."
| There also was a combination radio
receiving set and phonograph. This in
strument Is said to be revolutionizing
| the motion picture theaters In some
parts OF the country. The management
! Of a theater. with one of these instru-
mcnts. can give his patrons all the
radio concerts, and then when the con-
certs are ended he can turn on the
phonograph.
Applicants for radio operators licenses
will be examined free OF charge by
United States inspectors. The show will
be open again from this afternoon
until midnight. W. G. White OF the
