ward the television art in its present
state. In addition the commission has
refused to sanction televiSion'S step
ping out" of the laboratory to offer its
services for sponsored, or paid-for, pro-
grams of an advertising nature. The
commissions contention Is that licenses
to operate in the bands Of short waves
reserved for television, each 100 kilo-
cycles wide, are granted for expert
mental operation only.
40 Countries Ratify Agreement.
There are today about 20 television
transmitterS ION the air" for scheduled
operations.
one by one the nations of the earth
are proclaiming their adherence to the
International Radiotelegraph Conven-
ton, drawn UP and signed by represent
ativeS of about 80 countries in Wash
ington in 1927. The Department OF
State, repository of the treaty by rea-
,, son of the fact that the United States
was host to the conference, announces
that ratifications have been deposited
by 40 countries.
The International Radiotelegraph Con-
vention regulates the international uses
of radio setting aside the wave lengths
that shall be used for various types Of
service and otherwise prescribing inter-
national uSages. The conferences which
brought about the treaty were held in
Washington and were presided over by
Herbert Hoover who was chairman OF
the American delegation.
Another such conference is scheduled
to be held in Madrid in 1882. and by
that time it is expected that the legis-
latures of all the signatory nations will
have ratified the action of their delega-
lions to the Washington conference.
Meanwhile the ratification Of Latin
American countries are notably lacking,
only Mexico, Chile and Venezuela hav-
ing deposited theirs.
The United States Senate was first
to ratify, on october g. 1928. Within
three weeks the Canadian Parliament
from Norway, Netherlands, Dutch East
Indies, Surinas, Curacao, Denmark,
Belgium, Belgian Kongo, mandate ter
ritory of Ruana- Urundi, Great Britain,
! Austria, British India, Irish Free State

| Gulf of Guinea Colony, Morocco tex

Libanais Territories. Estonia, Mexico
Australia, Siam, Bulgaria, Portugal, Por-

STA, Chile, Greece, Liberia and China.
Russia Adheres Voluntarily.
In addition notices of adherence have
been received by the Department OF
! State from Latvia, Iceland and the
Free City of Danzig. Practically every
nation on earth using radio is believed
to be adhering to the terms of the
treaty on account of the international
ramif1cations of radio. Even Russia
| despite the fact that it was not invited
to participate in the conference, in view
| OF the absence OF diplomatic relations
with the host Government, is under
stood to be adhering voluntarily.
| Slower than many other major cities
| in getting its police radio system under
way, New York City, nevertheless, is
making ambitious plans for the use OF
radio in crime detection and pursuit
Not only does the New York Police De-
partment propose to transmit instruc-
tions to squad cars via radio, which is
| the chief use OF radio in police work
today, but it intends to employ its sys-
tenn to broadcast instructions to New
Ycrk's recently established unit of sky
| police.
Instructions to aviators by radio is
/ nothing new, but the use of radio by
! flying policemen has not been under
taken elsewhere, for the simple reason
that few, If any, other cities have police
aviation units. The scheme is perfectly
feasible and will undoubtedly be sane
toned by the Federal Radio Commission
when requests are made for special wave
, lengths for the purpose.
| In the meantime, while New York is
| tagging in the actual construction of a
| police radio network, systems have been
! established or are being established in
such cities as Chicago, Detroit, st.
Louis. Cleveland Washington, San
| Miami.
