SECURITY OF SIGNAL MESSAGES
Telegrams and telephone messages
Mention has already been made of the danger of the leakage of
important information through Arab employees of the Posts and Telegraphs

control under Martial Law might minimise the risks, but they cannot be
eradicated altogether unless a very large staff is available. Certain
palliatives can however be applied, and the following were adopted in
Palestine
The installation of "monitors" in civil exchanges.
