growing wider and wider as the expert

has stations in operation at the following
points: Cape Elizabeth. Me-; Portsmouth

Trying All Systems.
The Navy Department is experimenting
with all systems, Marconrs only, excepted.
It has never been able to do business with
him. He offered to equip all of the ships
and stations desired for the sum of 500 600
a year. on condition that his system should
be used exclusively, but the Secretary of
the Navy refused to consider such a prop
osition. Marconis system is used by the
British and Italian navies to the exclusion
of all others, and has a monopoly in
Italy. Great Britain, however, will grant
a. license to any company. 1t will not toll
crate a monopoly. Marconf has nearly all
>the transatlantic liners except the Ger
mans, which are equipped with Telefunken
instruments. Marconi has established
shore stations to communicate with his
ships, but they will not receive messages
sent by any other system.
Our government gave Marconi permission
to equip the two lightships that guard
Nantucket shoals, and the New York Her
aid Company was permitted to use the
lighthouse on Nantucket island; but these
privileges were withdrawn because the OPP
orators refused to receive any but Marconi
messages. The weather bureau now occu-
pies those points with it's instruments.
The navy is dealing with four companies
so as to get the best from all; and the off,
GERS of the equipment bureau say that each
system has its special merit and advan-
tages. The American De Forrest Wireless
Telegraph Company has the largest num-
Der of stations and is the only one which
does commercial business Mr. De For
rest, the inventor, installed a large sta
ton at the st. Louis exposition, which was
visited by hundreds of thousands of people
His company has stations at Portland, Me-
New Haven Manhattan Beach, AZ Broad
way, New York city; Cleveland, Chicago,
st. Louis, Denver, Cape Hatteras, Savan-
nah, Key West, Havana, New Orleans Gal
weston and other points along the coasts,
and has contracts with companies owning
coasting steamers to convey messages to
and from. their vessels while at sea. The
and the Gulf ports can talk with his en-
ployers at any time.
The second system belongs to the Ma
tfonal Electric Signal Company and was
invented by Mr.. r. A. Fessenden, a we'll
known electrical engineer, who has been
associated with the Edison and Westing-
house companies; was professor at Pur-
due University; was connected with the
weather bureau; and has written a great
deal about electrical subjects
The Internal Telegraph Construction
Company has system invented by an
electrician named Shoemaker, who was for
merly with the De Forrest Company.
Operating German System.
Our government is also operating with a
German system invented by Professor Slaby
of Charlottenburg and Count Arco of Ber-
lin. These gentlemen came out ahead in
a series of tests conducted by the Navy De-
partment in 1908, and the government pur-
chased several sets of their wireless appa-
ratus which was the first installed upon
American ships. Slaby and Arco after
ward consolidated with the Braun Company
of Berlin, and have since merged with the
General Electric Company of Germany
Their system Is now called 'Telefunken,"
and has been in use by the Russians during
the war. 1t is also used in the German
navy and very generally throughout the
world.
The outfit at Chefoo. which was pulled
down and confiscated by the Chinese gov
eminent at the demand OF Japan, belong
ed to the Slaby-Arco Company.
England, Germany. France and Italy are
also investigating and experimenting with
wireless telegraphy but they are tied to
certain systems and cannot go outside.
the United States has contracts giving ex-
elusive RIGHTS to cortain cOupauiea. and are
