MoreExcerpt from Manual for the Solution of Military CiphersThe capture of messengers is no longer the only means available to the enemy for gaining information as to the plans of a commander.

All radio messages sent out can be copied at hostile stations within radio range. If the enemy can get a fine wire within one hundred feet of a buzzer line or within thirty feet of a telegraph line, the message can be copied by induction. Messages passing over commercial telegraph lines, and even over military lines, .

Can be copied by spies in the offices. On telegraph lines of a permanent nature it is possible to install high speed automatic sending and receiving machines and thus prevent surreptitious copy ing of messages, but nothing but a secure cipher will serve with other means of communication.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
