MESSAGE BLANKS

[Illustration]

The heading “From” is filled in with the name of the detachment sending the information:  as “Officer’s Patrol, 7th Cav.”  Messages sent on the same day from the same source to the same person are numbered consecutively.  The address is written briefly, thus:  “Commanding officer, Outpost, 1st Brigade,” In the signature the writer’s surname only and rank are given.

This blank is four and a half by six and three quarters-inches, including the margin on the left for binding.  The back is ruled in squares, the side of each square representing 100 yards on a scale of 3 inches to one mile, for use in making simple sketches explanatory of the message.  It is issued by the Signal Corps in blocks of forty with duplicating sheets.  The regulation envelope is three by five and one-fourth inches and is printed as follows:
