PETTY OFFICERS' RATING MARKS.

All petty officers wear a rating device on the sleeve of the outer
garment above the elbow. If they belong to the starboard watch the mark
will be sewed on the right sleeve; if the port, on the left.

The petty officers' device always has a spread eagle above it. The
specialty mark indicating to which department he belongs is just below
in the angle formed by the chevrons. The chevrons indicate the class.
Three chevrons, first class; two, second class, and so on. The chief
petty officers have an arch of the same cloth connecting the two ends
of the top chevron.
