CHAPTER IV.

THE FIELD MESSAGE.

_Definition._--The term "field message" is applied to all messages sent

over field lines of information. All field messages for transmission

over field lines of information by electrical or visual means should be

plainly written by the sender on the blank forms in the United States

Army Field Message Book. The practice of verbally delivering telegrams

to enlisted men for transmission should invariably be discouraged.

"In framing telegrams, all words not important to the sense will be

omitted. The last name of the officer addressed, or his title, and the

last name of the sender are generally sufficient." (Paragraph 1198,

Army Regulations.)

_The blank form._--The United States Army Field Message Book issued

by the Signal Corps is 4-5/8 inches wide by 6¾ inches long, and

contains 40 message blanks with duplicate tissue sheets and two sheets

of carbon paper.

The message is written on the yellow sheet, which can be torn out for

delivery. The carbon sheet is attached to the book, and contrary to the

custom in most carbon duplicating books, is placed _under_ the tissue

sheet when a message is being written. When not being used, the carbon

sheet should invariably be kept in the back of the book. When the upper

carbon sheet has become worn out, it should be torn out and the second

carbon sheet used instead. The blank form is shown in figure 16. The

back of the blank is ruled in squares and provided with scales for use

in making sketches.

FIG. 16.]

_Writing the message._--In writing the message the name of the sending

detachment should appear after the heading "from" on the upper line,

as "from Headquarters 1st Brigade," while the location of the sender

should appear on the second line after the heading "at." The heading

"hour" on the third line should show the hour the message was _written_

and not the hour the message was transmitted. The heading "received" at

the bottom of the page is filled in by the addressee and shows the time

of the receipt of the message by him.

INSTRUCTIONS TO OPERATORS.

_Use of message blank._--The field message blank will be used for field

messages both sent and received.

_Duties of sending operators._--The _sending_ operator will enter the

time when the message is handed him for transmission in the left-hand

corner at the bottom of the blank opposite the word "Received." He will

enter in the proper places, at the head of the blank, the number of

the message, the call letter of his station, with his personal signal,

the check (number of words or groups of cipher contained in message,

counting address and signature), and, after "OK" has been received, he

will enter the time the message was sent, and the call letter of the

receiving station, with the personal signal of the receiving operator.

_Order of transmission._--To transmit a message, the operator will

send: (1) The number of message and call letter of his station; (2) his

personal signal; (3) the check; (4) "fm" followed by name of sending

detachment; (5) "at" followed by location of sending detachment and

date; (6) "Ho" followed by hour (a. m. or p. m.) message was written;

(7) address in full; (8) period, (· · -- -- · ·); (9) body of message;

(10) "sig" (signature follows); (11) signature.

_Duties of receiving operators._--The _receiving_ operator will add to

the message received, the month, date, and year, and omit the "sig,"

"fm," and "at," and, after satisfying himself that the check and number

of words correspond will give "OK" followed by the call letter of his

station and his own personal signal. He will then enter in the proper

places, at the head of the blank, the call letter of his own station,

with his personal signal and the time the message was received.

_Communications confidential._--Communications transmitted by telegraph

or signals are always confidential and will only be revealed to those

officially entitled to receive them.

_Checking the message._--In preparing the "check" of the message, all

words and figures written in the address, body of the message, and the

signature will be counted.

In counting the check of a message, all words, whether in plain

English, code, or cipher, pronounceable or unpronounceable, or initial

letters, will be counted each as one word. The abbreviations for the

names of places, cities, towns, villages, States, Territories, and

Provinces, will be counted as if written in full. In the names of

towns, counties, countries, or States, all of the words will be counted.

Abbreviations of weights and measures in common use, and cardinal

points of the compass, will be counted each as one word.

To prevent liability to error, numbers and amounts should be written in

words, and when not so written, the receiving operator will request

that it be done. If the writer declines to write the amounts in words,

the message will be accepted as written, and each figure will be

counted as one word.

Figures, decimal points, and bars of division, and letters will be

counted each separately as one word.

In ordinal numbers, the affixes, st, d, nd, rd, and th, will each be

counted as one word.

In transmitting the telegram shown in figure 16, the following would be

sent by the operator:
