The position is with the flag or other appliance held vertically, the
signalman directly facing station with which it is desired to
communicate. The "dot" is to the right of sender, embracing an arc of
90 deg., starting with the vertical and returning to it. The "dash" is a
similar motion to left. "Front" is downward directly in front and
instantly returned to vertical; it indicates a pause or conclusion.

For communication between the firing line and the reserve or commander
in rear, the subjoined signals (Signal Corps codes) are prescribed and
should be memorized. In transmission, their concealment from the enemy's
view should be insured.
