In making D, J, K, P, T, and V, the arm in the vertical position should be brought exactly in front of the body by carrying the shoulder in almost under the chin, twisting the elbow in until it is directly before the eyes, and the forearm held in the vertical position with the palm to the rear. When so done there is no possibility of this position being mistaken for any other.
"Manila Milkman" may be sent without changing the position of the right hand. In making I, be sure to twist body well to the right in order that the left arm may be seen in the upper slanting position to the right. City and similar words may be so made.
D may be made with either hand.
Be sure how next letter is made before moving hands. Make no false motions.
Acquire accuracy; then try for speed.
"CHOP-CHOP." The "chop-chop" signal is made by placing both arms at the right horizontal (that is, by bringing the left arm up to the position of the right arm as in the figure for letter "B"), and then moving each up and down, several times, in opposite direction, making a cutting motion.
END OF WORD. After each word the "Interval" signal is made.
END OF SENTENCE. After each sentence the chop signal is made twice.
END OF MESSAGE. At the end of a message the chop signal is made three times.
ERROR. Signal "A" several times quickly, followed by interval; then repeat the word.
