Of an accident. The climatic conditions 90 not
IN any way interfere with the accuracy OL INC

loss of time and expense which. under the present
system, invariably follow severe storm
The originator Of the system says that one OF the
very material points in which his system uIHeI8
from the MarcOni Is the absence OF the coheEeE
used by MaTconi to pick up the eIecUlc waves, ll %
found that there is a great deal OF atmospheric
electricity I'm California which would aHect tne
coherer the same as electric impulse sent OUT
from a sending station. For that reason the
coberer was discarded. and after TWO HOhtls
labor device was perfected that oyercame the
atnnospherc disturbance. 1t is IN the nature oL
YER, sensitive receiver which responds much more
quickly to every impulse than did the coherer'

ton calculated to double this speed
The equipment Of each station consists OF an en-
p-re and dynamo. induction coil Morse Key spark
halls or terminals. and mast The dynamo plays
its mart and the current is opened ana closeu
through the induction coil by the manipulation OF
the sending key by the operator who transmits
,ts message through the ether in the same manner

and the dash being carried through space, and re-

" a Sener who is in charge of the station AZ
Catalina Island, was for seventeen years teiesEap
onarator and train dispatcher for the Pennsyl-
,,ania Railroad Mr.. Sener was asked IL the sys-
tenn had been perfected to that extent where aoso-
IutA secrecy can be assured In the sending or
messages He replied that such a contingency had
been provided for by system of tuning the instru-
ments ITO read a wireless message an outslde
station would have to be in exact tune or Ylora-
tory unison with our stations the same mo-
ment" he said, land can change the tune
of our instruments every second If We desire II
will be seen that it would be very difficult matter
for an outside party to pick up one OF our mes
saEes."
Mr. sener saws that climatic changes appear TO
have no noticeable effect the wireless, except
that while rain descends dense fog prevails the
messages come more clearly. This would seem
a dispensation OF Providence" ne says, "as one
will readily recognize the great Importance Of such

lying points where ships in heavy fog might
