ed use by telegraph companies, press as
sociations, and railroads. The printing
telegraph consists essentially Of a send
ing instrument, equipped with a key
board similar to that of typewriter,
electrically connected with a receiving
instrument in such manner that the
latter automatically reproduces what is
typewriter on the sending instrument.
Without the printing telegraph it would
have been difficult or impossible to han
die the increased telegraph business dur
ing the great war.
Train Dispatching By Telephone.
A special feature Of the report, relat
ing to train dispatching, is of some in
terest. The first installation Of tele
phone and selector equipment for train
dispatching was completed on the lines
of the New York Central railroad in Oc-
tober, 1907, The use of the telephone
for this purpose has increased rapidly.
The report shows, for 1917, los lines en-
ploying this method Of train dispatehing,
as against AZ in 1902. The mileage of
telephone pole line for train dispatching
purposes was o5,26s, an increase of 67.6
per cent as compared with 1912; and the
mileage of wire was 20l ,662, an increase
Of 55.7 per cent over 1912. The total
line mileage of railroads reporting the
use Of telephones for transmitting train
orders in 1917 amounted to ll0404. 1t
is asserted that not single accident has
resulted from the use of telephones in
train dispatching.
Wireless Telegraph Systems.
All the wireless telegraph systems in
the United States were taken over by
the federal government under authority
Of an executive order issued April 6,
1917, for which reason the figures for
1917 give little indication Of the increase
in commercial wireless telegraph opera
tions during recent years. The systems
reported for 1917 numbered 3, as COM
pared with 4 in 1912 and in 1907 and
the number Of tower stations was 81, as
compared with II in 1912 and III in
1907. The number of messages handled
prior to April was l22,244. No exact
record Of the number transmitted during
the period of government operation il
available, but il is roughly estimated
that 100000 messages were handled be-
tween April 6 and Dec 81, 1917 This
number, added to that already given,
would make total of more than 10000,
representing an increase df approximate
ly So per cent as compared with 1912
and Of l9l per cent over 1907,
The total income and the net inec.L
increased greatly The former aggregat-
ed 81 ,3S5, 060 in 1917, representing a gain
Of l07 per cent over 1912 and Of | 1877
per cent over 1907; and the latter
amounted to 5000 .526, as compared with
net income Of S4,73S in 1912 and a net
deficit Of S53,53s in 1907 The employees
numbered $50, a decrease of 3s.s per
cent from the corresponding number in
1912, but an increase Of 233 per cent over
the number for 1907; and their salaries
and wages aggregated S46l 402, an in
crease Of liz per cent over 1912 and Of
464.3 per cent over 1907
In addition TO the commerca Shore
stations, there were in operation during
the early part Of the year 6,0s0 general
and restricted amateur stations. IS spe-
cial amateur stations, Is experimental
stations, and AZ training schools.
The records of the bureau Of nayiga
tion, Of the navy department, show that
on June 30 1915, there were in operation
1874 commercial shore stations and S3s
commercial ship stations. OF the shore
stations, 81 were in continental United
States, % in Alaska in Hawaii, and
in Porto Rico.
Government Wireless.
The government has erected wireless
plants at various points along the Allan
tic ard Pacific coasts and a. Pearl Har-
bor, Hawaii, and Cavite, in the Philip
pines The government shore stations,
according to the reports Of the bureau Of
navigation numbered 1876 on June 30,
1918, Of which s. were in continental
United States, 20 ia Alaska, 10 in the
Philippine Islands, in the canal zone,
