RAILROAD WIRELESS IN CANADA
(from 'The Wireless Age", July 1916)
It has been announced in a newspaper that wireless
telegraph will be used instead of the old poles and wire
by the new Canadian government railway which is to connect
Hudson Bay with the Canadian Northern at Le Pas, Manitoba.
The chain of wireless stations has already been constructed
between Port Nelson and Hudson Straits.
5,073 STATIONS IN THE U.S.
(from "The Wireless Age", June, 1916)
The Bureau of Navigation, Department of Commerce,
has issued the 1915 edition of "Radio Stations of the
United States." This list shows that there are now
5,073 wireless stations in the United States, an increase
of 1,139 since 1914. They are classified as follows:
Government and commercial land stations, 224;
Government and commercial ship stations, 895;
Special land stations, 118;

If anyone is reading this who knows the Manitoban with
initials A.D., who resided in Middlechurch, Manitoba,
and sent in the following questions which were published
in "The Wireless Age" of May, 1916 - let the family have
a copy.....(and supply us with A.D.'s full name)
Ques.-- (1) Is the discharge from a transformer with a
secondary potential of 25,000 volts as dangerous as a current
of that voltage direct from a generator? if not, why not?
Ans.-- (1) With similar frequencies, the effect would
be identical in either case; both being considered dangerous
to human life. We have never heard of a generator that gave a
potential of 25,000 volts direct from the armature.
Ques.-- (2) Is it possible to use a telephone induction
coil or a medical coil for wireless transmission? Which of the
two would be better?
Ans.-- (2) If the secondary potential of the coil is
sufficient to give a spark discharge, it can be used as a radio
transmitter. The one giving the highest voltage should be
employed. Special information concerning the diagram of
connections, etc. is given in the book "How to Conduct a
Radio Club."
Note: The book mentioned above had 128 pages, 116 illustrations,
and was written by E. E. Bucher. Contents were thus:
"Describing Parliamentary Procedure indoor and outdoor experi-
ments, 5,000-mile Receiving Set and many other features."
The price was 50c postpaid (or $1.75 with one year's Wireless Age).

On March 1, 1916, the following letter was sent by U.S. President
Woodrow Wilson to the National Amateur Wireless Association (Pres.
Guglielmo Marconi):
"THE WHITE HOUSE
WASHINGTON
The organization of the amateur radio operators
of this country under the direction and control of
representative American civil, military, and naval
officials, would undoubtedly be a valuable asset to
the nation, as it is only through the agency of such
organized bodies that maximum efficiency can be ob-
tained. The value of such an organization in co-
ordinating the activities of a large number of
specially qualified young men along carefully planned
lines will be of great benefit not only in an educa-
tional way to the young men themselves, but also to
the country at large when the necessity for their
employment, individually or as an organization, may
develop.
(signed) Woodrow Wilson
Note: On the National Advisory Board of Vice Presidents of the
National Amateur Wireless Association, we find the name of
HIRAM PERCY MAXIM, President, American Radio Relay League.
